Using CONFigure with a Math Operation

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 HP BASIC and QuickBASIC (see next page).
HP-IB Operation Using HP BASIC
10 DIM Rdgs(1:5)
20 ASSIGN @Dmm TO 722
30 CLEAR 7
40 OUTPUT @Dmm; "*RST"
50 OUTPUT @Dmm; "*CLS"
60 OUTPUT @Dmm; "CALC:DBM:REF 50"
70 OUTPUT @Dmm; "CONF:VOLT:AC 1,0.001" ! Set dmm to 1 amp ac range
80 OUTPUT @Dmm; "DET:BAND 200"
90 OUTPUT @Dmm; "TRIG:COUN 5"
100 OUTPUT @Dmm; "TRIG:SOUR IMM"
110 OUTPUT @Dmm; "CALC:FUNC DBM"
120 OUTPUT @Dmm; "CALC:STAT ON"
130 OUTPUT @Dmm; "READ?"
140 ENTER @Dmm; Rdgs(*)
150 PRINT USING "K,/"; Rdgs(*)
160 END
