E1412A Multimeter Application Examples Keysight E1412A Multimeter Application Information
SAMP:COUN 10
Set sample count to 10 per trigger.
INIT
Puts multimeter in wait-for-trigger state. EXTernal triggers occur
here to initiate measurements. Measurements are stored in
multimeter internal memory.
FETC?
Transfer measurements from the multimeter internal memory to the
output buffer and retrieve them with the computer.

Enter reading into computer.
Comments
–
You must provide a TTL external trigger signal to the E1412A front panel
“Trig” input BNC. Measurements are triggered by low pulses of this signal.
Each trigger results in 10 readings.
–
The CONFigure command configures the multimeter for the function
specified. This CONFigure command specifies a range parameter of 18
(expected input is 18V; the multimeter sets a range to accommodate that
input which will be 100V). It does not initiate the measurement.
– Trigger source ( TRIG:SOUR ) is set for an external trigger. A trigger count
( TRIG:COUN ) of 3 is set; the multimeter will accept three external triggers.
–
The sample count ( SAMP:COUN ) is set for 10 samples per trigger.
–
The INITiate command puts the multimeter in the wait-for-trigger state.
The trigger source is an “ EXTernal ” hardware trigger. You provide this
trigger and input it on the “Ext Trig” BNC connector which initiates the
measurement process. This will cause the multimeter to make
30 measurements; 10 samples for each of three triggers.
–
The FETCh? command causes the readings to be transferred to the output
buffer and you must provide the I/O construct to retrieve the readings and
enter them into the computer.

Maximizing Measurement Speed (no trigger delay, short integration time)
*RST
Reset the multimeter.
CONF:VOLT:DC 18
Configure for dc volts, expected input = 18V.
