FETCh:ACCuracy?
Queries the accuracy of the last measurement.
The R&S LCX returns the accuracy of the impedance (δ|Z|) in percent, and the phase
angle (δΘ) in degrees.
If an invalid value is returned, the instrument reports error code -230.
Return values:
<Magnitude Accuracy
Percentage>
Selects the magnitude accuracy.
<Phase Accuracy
Degree>
Selects the phase accurracy.
Example: See Example "Querying measurement values" on page 205.
Usage: Query only
Manual operation: See "<measurement accuracy>" on page 73
FETCh:CURRent:DC?
Applies to DC measurements only.
Queries the DC current measurement value of the last measurment.
If an invalid value is returned, the instrument reports error code -230.
Return values:
<DC Current
Measurement Value>
Default unit: A
Example: See Example "Querying measurement values" on page 205.
Usage: Query only
FETCh:CURRent[:AC]?
Applies to AC measurements.
Queries the AC current measurement value of the last measurement.
If an invalid value is returned, the instrument reports error code -230.

FETCh:VOLTage:TRANsformer[:PRIMary]?
Queries the recently measured primary transformer voltage value.
If an invalid value is returned, the instrument reports error code -230.
Return values:
<Primary Voltage
Measurement Value>
Default unit: V
Example: See Example "Querying measurement values" on page 205.

Example: See Example "Querying measurement values" on page 205.
Usage: Query only
FETCh[:TYPE]? [<Measurement Type Pair>]
Queries the recently measured values for the specified measurement pair.
Without specifying the measurement pair, the instrument returns the values of the pri-
mary measurement pair.
If an invalid value is returned, the instrument reports error code -230.
