Agilent E8462A Scanning Voltmeter Application Examples 121 Chapter 4
Note: When the multimeter buffer fills, measurements are suspended until
readings are read from the buffer (by the computer) to make space available.
Voltage
Measurements
Line 90 initiates a DC voltage measurement.
2-Wire Ohms
Measurements
To make 2-wire measurements, change line 90 in the voltage measurement
example to read:
90 OUTPUT 70903;"MEAS:RES? (@100:131)"
4-Wire Ohms
Measurements
To make 4-wire measurements, change line 90 in the voltage measurement
example to read:
90 OUTPUT 70903;"MEAS:FRES? (@100:131)"
(NOTE: 4-wire channels are made by pairing banks 0 and 2, banks 1 and 3,
banks 4 and 6 and banks 5 and 7. Two lines from each bank will
automatically be paired to form the 4-wire channel)
10 !Dimension a computer array to store readings.
20 DIM Rdgs(1:32)
30 !Clear and reset the scanning voltmeter (voltmeter & multiplexer) .
40 !See Figure 4-1 for module addresses.
50 CLEAR 70903
60 OUTPUT 70903;"*RST"
70 !Configure the multimeter for DCV measurements and
80 !specify the channel list to scan (channels 00 through 31).
90 OUTPUT 70903;"MEAS:VOLT:DC? (@100:131)"
100 !Enter and display measured readings. Note: The number of
110 !channels in the scan list must equal the number of elements in
120 !the array Rdgs to use Rdgs(*).
130 ENTER 70903;Rdgs(*)
140 PRINT Rdgs(*)
150 END
