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. The second section, “Getting Information from the Spectrum Analyzer, n show[...]

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. If a properly selected sequence of instructio[...]

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. Program Example for the RS-232 Interface 10 'File = 232PROGl 20 OPEN &[...]

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. We can add instructions to[...]

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. The CF command corresponds to the center freq[...]

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 HP-IB Interface In the following program, the exclamation point (!) allows the words that follow to be ignored by the co[...]

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. 10 ‘File = 232PROG3 20 OPEN "COMl:9600,N,8,1" AS #1 30 PRINT #l,"IP;" 40 PRINT #l,"SNGLS;TS;" 50 'Ask for the center fre[...]

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. For example, in the second program of this chapter, we placed a marker at the highest peak of a trace and the valu[...]

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. Program Example for the RS-232 Interface 10 'File = 232PROG4 20 OPEN "COMl:9600,N,8,1" AS #l 30 PRINT #l,"IP;" 40 &[...]

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. Use variables for function values. List variables at the beginning of the program, 4. Activat[...]

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. Program Example for the HP-IB Interface 10 !FILE: "IBPROG7"[...]

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. The fi[...]

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). This section describes all the available trace data formats. The HP 8590 Series spectrum analyzer provides five formats for trace data transfers: real number (P) format, binary (B) forma[...]

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. 10 OUTPUT 718;"IP;CF 300MHZ;SP 20MHZ;SNGLS;TS;" Zzke a measurement sweep. 20 [...]

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). Unlike the A-block[...]

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;FORMAT OFF INTEGER Trace-a(l:401) OUTPUT Sa;"AUNITS DBM;" OUTPUT Sa*"RL?*" ENTER Sa;Ref-Ik PRINT Ref-lev OUTPUT Sa;"TDF B;TRA?;[...]

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. These bytes are the ASCII character “f’, “A”, and two-byte number represent[...]

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”. These characters indicate[...]

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. For log scale data, each point is equal to 0.[...]

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. The a[...]

‘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. See line 10 of the example. Use unique names (unique from the analyzer[...]

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. Turning the spectrum analyzer off, then on or pressing @iZK) will res[...]

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. Unlike user-defined variables, the elements of user-defined traces are of[...]
