If There Is a Problem This section offers suggestions to help get your computer and spectrum analyzer working as a system. The test programs provided in this chapter let you know if the connection between the computer and the spectrum analyzer interconnection is working properly.
2 Writing a Program What You’ll Learn in This Chapter This chapter introduces spectrum analyzer programming. The first section of this chapter, “Writing Your First Program, n helps you write your first spectrum analyzer program and introduces programming fundamentals.
Writing Your First Program When the spectrum analyzer has been connected to a computer via HP-IB or RS-232 interface, the computer can be used to send instructions to the spectrum analyzer. These instructions tell the spectrum analyzer such things as frequency span, resolution bandwidth, and sweep mode.
Finally, in line 60, we end the program with the END command. (If you forget to include the END command, the computer will give an error message.) Enter the program lines, press (RUN) on the computer, and watch the spectrum analyzer display as it completes each instruction.
Modifying the Program Remote operation of the spectrum analyzer is similar to manual operation. Remote measurements are executed by commands that correspond to front-panel keys and softkeys. The first chapter in the spectrum analyzer operating manual shows you how to make a simple measurement using the calibration signal.
When a certain measurement is repeated often, a computer program can save time. In addition, the computer is less likely to make an error than an operator manually entering the same instructions from the front panel. Program Example for the RS-232 Interface First, we set the center frequency to 300 MHz.
Enhancing the Program with Variables In the last program, specific center frequency and span values were set. By modifying the program, we can cause different values to be set each time the program is run.
Program Example for the RS-232 Interface In the following program, the apostrophe (‘) allows the words that follow to be ignored by the computer. Thus, they serve as comments in the program.
Getting Information from the Spectrum Analyzer The first part of this chapter demonstrated techniques for setting spectrum analyzer parameters. This section demonstrates a technique for getting information out of the spectrum analyzer.
Finally, we print the values on the computer screen: "THE SIGNAL PEAK IS . . . dBm AT . . . MHz" Before we end the program, we return the spectrum analyzer to continuous-sweep mode and local control.
Programming Guidelines 1. Perform the measurement manually, keeping track of the sequence of functions used. 2. In the written program, execute an instrument preset (IP) and set single-sweep mode (SNGLS) before setting other spectrum analyzer functions.
3 Programming Xbpics What You’ll Learn in This Chapter This chapter contains the following advanced programming techniques and topics. n An example of moving and saving trace data from the spectrum analyzer into the computer. n An example of how spectrum analyzer states are saved with the computer, then returned to the spectrum analyzer.
Controlling Trace Data with a Computer Using sample programs, this section shows you how to read trace data and store the data with your computer. Reading Trace Data The following program, which has been annotated with comments, reads a trace from the spectrum analyzer and stores the trace data in a variable.
Program Example for the RS-232 Interface 10 'File = 232PROG5 20 OPEN "COMl:9600,N,8,1" AS #l 30 'create a 401-point trace array 40 DIM TRCA(401) 50 PRINT #1 "IP.
Saving Trace Data The trace data in the previous program can be stored on a computer disk by making three program modifications. 10 !FILE: "IBPROGG" 20 !create a 401 point trace array: 30 RE.
Program Example for the RS-232 Interface 10 'File = 232PROG6 20 OPEN "COMl:9600,N,8,1" AS #l 30 'create a 401-point trace array 40 DIM TRCA(401) 50 PRINT #l,"IP;" 60 &apo.
Reading Trace Data from a Computer Disk If we want to return trace data to the spectrum analyzer for later viewing, we must work the “saving” process in reverse. The following program reads a trace previously stored on a computer disk and stores the trace in an array variable.
Saving and Recalling Instrument States The spectrum analyzer’s control settings (or its “state”) can be saved with a computer and retrieved later to streamline test sequences or repeat manual measurements. Control settings can be stored in one of eight state registers in the spectrum analyzer, in computer memory, or on a computer disk.
Program Example for the HP-IB Interface 10 !FILE: "IBPROG8" 20 !define 202 character string: 30 DIM Learn_string$[202] 40 !create 401-point array to store trace: 50 INTEGER Trace,a(l:401) 60.
The HP-IB version stores the trace in the variable called Trace-a(*). The state of the spectrum analyzer is stored in the variable Learn-string& These two variables are then saved in a file called STATE.
Program Example for the RS-232 Interface 10 'File = 232PROG8 20 OPEN "COMl:9600,N,8,1" AS #I 30 'Define 202-character string 40 DIM LEARN$(202) 50 'Create 802-character string.

Different Formats for Trace Data Transfers Two different ways to format trace data using the TDF command were introduced earlier in this chapter (TDF P and TDF B).
Example of Using the P Format This example sends trace datatothe computer and backtothe spectrum analyzer using P format. Note The spectrum analyzer mustbeinthelog amplitude scale to use the TDF P format. 1 REAL Trace_data(l:401) Declare an array for trace data.
B Format The B format allows you to receive or send trace data in a binary format. The B format provides the fastest data transfer and requires the least amount of memory to store data. Each data point is transferred in binary as two 8-bit bytes. The data points are in the internal representation of measurement units (0 to 8000).
The following programming converts binary data to dBm. 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 ! 859X binary data to real numbers Sa=718 ASSIGN (OSa,bin TO Sa;FO.
A-Block Format The A-block format is similar to binary format in that each data point is sent as two 8-bit bytes (this, too, is in the internal representation of measurement data). A-block format also transfers a four-byte header before the 401 points of trace data.
I-Block Format Note The I-block format is not recommended for use with the RS-232 interface (Option 043). The I-block format transfers data points as two 8-bit bytes in the internal representation of measurement data. In addition to transferring trace data, I-block format also transfers the characters I‘#” and “I”.
M Format The M format is for sending trace data only. It formats the trace data in the internal format used by the spectrum analyzer, also known as measurement units. Refer to Figure 3-1. The displayed amplitude of each element falls on one of 8000 vertical points with 8000 equal to the reference level.
Index Number 1 ‘Ihble 3-1. Measurement Units Description A number within the range of 8161 to 32,767 measurement units is obtainable with trace math operations only. The area from 8000 (reference level) to 8160 (1.6 dB above reference level) represents the amount a trace element’s amplitude can exceed the top graticule and still be valid.
‘Ihble 3-2. Summary of the Trace Data Formats Trace Data Format TDF P TDF B TDF A TDF I TDF M Description Real Number Format Binary Format A-Block Data Format I-Block Data Format Measurement Data Format Remarks Spectrum analyzer must be in log scale to use TDF P.
4 Creating and Using Downloadable Programs What You’ll Learn in This Chapter This chapter provides fundamental information about downloadable programs (DLPs). This chapter contains the following sections: w Creating a DLP. n Executing a DLP n Storing DLPs on a RAM card.
Creating a DLP This section contains information about how to create a DLI? This section contains the following procedures: w Use a user-defined function within a DLP.
‘lb Use a User-Defined Function within a DLP A user-defined function is created by using the FUNCDEF command. 1. Begin the user-defined function definition by using the FUNCDEF command, the label (function name) for the function you are creating, a comma, and then a delimiter.
To Use a User-Defined Variable within a DLP User-defined variables are variables that you create with the VARDEF or ACTDEF commands. User-defined variables remain in spectrum analyzer memory and retain their values until redefined, disposed of, or altered by MOV or math commands.
To Use a User-Defined Trace within a DLP Like variables, you should define user-defined traces outside of functions. User-defined traces retain their values until redefined, disposed of, or altered by the MOV command or a math command. User-defined traces are global in scope.
To Enter Values into a DLP To allow the spectrum analyzer user to enter a value into a user-defined variable with the analyzer front-panel keys use the active function definition command (ACTDEF).
To Create a Modular DLP A modular DLP is a DLP that is made up of several user-defined functions. Within a modular DLP, there may be a main FUNCDEF which calls subordinate FUNCDEFs. A subordinate FUNCDEF is a user-defined function that usually performs only one task, and is called by another FUNCDEF.
File name Date and author's name Program Description Define variable Define trace DefineFUNCDEF DefineFUNCDEF DeAneFUNCDEF DefineFUNCDEF DeEneFUNCEDEF Define Main FUNCDEF 10 !File name: EXAMPLE 2.
Executing a DLP This section contains information about how to execute a DLP This section contains the following procedures: n Execute the DLP by using a softkey. H Execute the DLP within a program. To Execute a DIP by Using a Softkey There are two ways to execute a DLP.
Storing DLPs on a RAM Card If the spectrum analyzer has a memory card reader installed in it, you can store the DLP on a RAM card, and, at a later time, load the DLP into analyzer memory from the RAM card.
To Load DLPs from a Memory Card into Analyzer Memory Once a DLP has been stored on a RAM card, it can be loaded back into spectrum analyzer memory when desired. DLPs remain in spectrum analyzer memory until disposed of with the DISPOSE command, ERASE command, or ERASE DLP MEM.
Determining the Amount of Memory Needed for a DLP FUNCDEFs, user-defined variables, user-defined traces, on event commands (for example, ONSRQ, ONEOS, and TRMATH), and user-defined softkeys all consume some amount of spectrum analyzer memory.
3. Determine the number of records on the RAM card that are in use. The number of records stored on the RAM card can be determined by cataloging the card, finding the starting record address for the last catalog entry, adding the number of records used for the last catalog entry to the starting record address, and then subtracting one.
‘lb Delete a DIP from Spectrum Analyzer Memory w Use the DISPOSE command to delete the DLP item from spectrum analyzer memory. A FUNCDEF can be deleted from analyzer memory remotely by using the DISPOSE command. The DISPOSE command can also be used to remove softkey functions, user-defined variables, and user-defined traces.
Using the DLP Editor The DLP editor functions allow you to create or modify a DLP with only an external keyboard connected to the spectrum analyzer (an external controller is not required). This section contains the following procedures: n Connect the external keyboard to the spectrum analyzer.
‘Ib Access the DLP Editor . Press (SAVE) or (RECALL), then INTERNAL CARD (so that INTERNAL is underlined), Catalog Internal , CATALOG ALL, and then Editor. Press IPause) on the external keyboard. Editor or m accesses the DLP editor. There are some differences between using Editor and IPause) however.
To Create a DLP 1* Press HEW EDIT, NEW EDIT to enter an individual DLP item (FUNCDEF, VARDEF, or TRDEF) into the buffer of the DLP editor. 2. Use the external keyboard keys to enter the DLP item. Because you are not using an external computer, the spectrum analyzer commands are entered without an OUTPUT or PRINT statement preceding them.
lb Modify the DLP 1. If necessary, press m to reenter the DLP editor. 2. If the DLP is not displayed, press EDIT LAST to display the previous contents of the DLP editor.
‘lb Modify a Catalog Item 1. 2. 3. 4. 5. 6. Press (‘1 or m, then INTERNAL CARD (so that INTERNAL is underlined). Press Catalog Internal , CATALOG ALL , and then Editor. (You can use one of the other catalog softkeys instead of CATALOG ALL . For example, you could press CATALOG DLP if you wanted only the DLPs cataloged.
DLP Programming Guidelines This section contains some suggestions that can make it easier to write a DLP, read and understand the DLP code, and find problems in a DLP. lb Make the DLP More Readable Here are a few suggestions which help make any program, including a DLP, more readable: n Write short program lines.
If a DLP causes the spectrum analyzer not to respond normally (for example, the spectrum analyzer seems to be in an infinite loop or an error message is displayed), try one or all of the following suggestions: n Press [PRESET]. n Press I-), More I of 3 , ERASE DLP MEM , ERASE DLP ME!! .
