If optional parameter All is applied, return actual voltage of all channels;
If no optional parameter is applied, return actual voltage of current channel.
Unit
V
Example
MEAS?
FETC?
MEASure[:SCALar]:POWer[:DC]?
FETCh:POWer[:DC]?
These two commands are used to read the output power of power supply.
Command syntax
MEASure[:SCALar]:POWer[:DC]? <nr>
FETCh:POWer[:DC]? <nr>
Optional parameter :
CH1|CH2|CH3|ALL
Returns
If optional parameter CH1|CH2|CH3 is applied to specify measure channel,
return actual power of the specified channel;
If optional parameter All is applied, return actual power of all channels;
If no optional parameter is applied, return actual power of current channel.
Unit
W
Example
MEAS:POW?
FETC:POW?
Note: Both fetch and measure instructions can read various parameters. The
difference is that fetch reads the last measured value, and measure reads the
re-measured value. fetch is faster and measure is more accurate.
