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
