Using CONFigure with a Math Operation
The following example uses CONFigure with the dBm math operation.
The CONFigure command gives you a little more programming
flexibility than the MEASure? command. This allows you to
“incrementally” change the multimeter’s configuration. The example is
shown in BASIC and QuickBASIC (see next page).
10 DIM Rdgs(1:5)
20 ASSIGN @Dmm TO 722
30 CLEAR 7 ! Clear GPIB and dmm
40 OUTPUT @Dmm; "*RST" ! Reset dmm
50 OUTPUT @Dmm; "*CLS" ! Clear dmm status registers
60 OUTPUT @Dmm; "CALC:DBM:REF 50" ! 50 ohm reference resistance
70 OUTPUT @Dmm; "CONF:VOLT:AC 1,0.001" ! Set dmm to 1 amp ac range
80 OUTPUT @Dmm; "DET:BAND 200" ! Select 200 Hz (fast) ac filter
90 OUTPUT @Dmm; "TRIG:COUN 5" ! Dmm will accept 5 triggers
100 OUTPUT @Dmm; "TRIG:SOUR IMM" ! Trigger source is IMMediate
110 OUTPUT @Dmm; "CALC:FUNC DBM" ! Select dBm function
120 OUTPUT @Dmm; "CALC:STAT ON" ! Enable math
130 OUTPUT @Dmm; "READ?" ! Take readings; send to output buffer
140 ENTER @Dmm; Rdgs(*)
150 PRINT USING "K,/"; Rdgs(*)
160 END
