Waveform Capture Commands
Waveform capture commands may be used to retrieve time domain voltage and current waveform
captures similar to those of a digital oscilloscope.
Query Format
FETCH:WAVEform:VOLTage#?
Description
Returns time domain data for voltage on selected phase #. # = 1, 2 or
3. Returns a string of <nr2> type numbers, comma delimited. Only a
single waveform may be queried in a command.
Note: In UPC Compatibility mode, a total of 512 data points are
returned. In LMX mode, 1024 data points are returned.
Returned Data Format
<nr2>, <nr2>, <nr2>,……, <nr2>
Query Example
FETCH:WAVE:VOLT1?
0.000, 0.0001, 0.0003…., 0.000
Query Format
FETCH[:WAVEform]:VLL#?
Description
Returns time domain data for voltage on selected Line to Line voltage
#. # = 1, 2 or 3. Returns a string of <nr2> type numbers, comma
delimited. Only a single waveform may be queried in a command.
Note: In UPC Compatibility mode, a total of 512 data points are
returned. In LMX mode, 1024 data points are returned.
Returned Data Format
<nr2>, <nr2>, <nr2>,……, <nr2>
Query Example
FETCH:WAVE:VLL1?
0.000, 0.0001, 0.0003…., 0.000
Query Format
FETCH:WAVEform:CURRent#?
Description
Returns time domain data for current on selected phase #. # = 1, 2 or
3. Returns a string of <nr2> type numbers, comma delimited. Only a
single waveform may be queried in a command.
Note: In UPC Compatibility mode, a total of 512 data points are
returned. In LMX mode, 1024 data points are returned.
Returned Data Format
<nr2>, <nr2>, <nr2>,……, <nr2>
Query Example
FETCH:WAVE:CURR?
0.000, 0.0001, 0.0003…., 0.000
Query Format
FETCH:WAVEform:INFO?
Description
Returns the output measurement frequency, date and time of
capture for the last waveform data fetched.
Returned Data Format
<nr2>, <dd/mm/yyyy>, <hh:mm:ss>
Query Example
FETCH:WAVE:INFO?
400.000, “05/21/2018”, “14:34:20”
