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.
Usage: Query only
FETCh:VOLTage[:AC]?
Queries the most recent AC voltage measurement value.
If an invalid value is returned, the instrument reports error code -230.
Return values:
<AC Voltage
Measurement Value>
Default unit: V
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.
Query parameters:
<Measurement Type
Pair>
DEFault | CPD | CPQ | CPG | CPRP | CSD | CSQ | CSRS |
LPD | LPQ | LPG | LPRP | LSD | LSQ | LSRS | RX | RPB | RDC |
MTD | NTD | ZTD | ZTR | GB | YTD | YTR
Return values:
<Primary
Measurement Value>
Selects the first measurement parameter.
<Secondary
Measurement Value>
Selects the second measurement parameter.
Example: See Example "Acquiring measurement readings" on page 205.
Usage: Query only

Example: Selecting the measurement function and setting the impedance range
The example represents the remote control commands for the measurement functions.
// *************************************************
// Select the measurement function by setting
// the type of component sample.
// Select the parameters to be measured,
// e.g., parallel inductance, dissipation
FUNCtion:MEASurement:TYPE L //impedance
FUNCtion:IMPedance[:TYPE][:PRIMary] LPD
FUNCtion:IMPedance:TYPE:SECondary ZTD
// *************************************************
// Activate automatic selection of the measurement function
FUNCtion:MEASurement:AUToselect
// *************************************************
// Activate automatic range selection
FUNCtion:IMPedance:RANGe:AUTO 1
// *************************************************
// Set the impedance and DC resistance ranges manually
FUNCtion:IMPedance:RANGe:AUTO 0
FUNCtion:IMPedance:RANGe[:VALue] 10E6 // 10KOhm
// *************************************************
// Query the measurement type and ranges
FUNCtion:IMPedance:RANGe:AUTO?

FUNCtion:IMPedance:RANGe[:VALue]?
// Response: 10E6
// *************************************************
// Lock the selected measurement range
FUNCtion:IMPedance:RANGe:HOLD ON
FUNCtion:IMPedance:RANGe:HOLD?
// Response: 1
// *************************************************
// Set source impedance to LowZ mode,
// i.e. set the output impedance 10 Ohm
FUNCtion:IMPedance:SOURce LOW
// *************************************************
// Query the output impedance setting
FUNCtion:IMPedance:SOURce?
// Response: 'LOW'
// *************************************************
// Set the transformer turn ratio range
