Measurement function
Queries the measured data without starting the measurement operation.
If FETC? is sent without making a measurement in advance, an SCPI error (-230,“Data corrupt or stale”) occurs, because there is no valid measured data. Be sure to use this command with the INIT command.
The second level node can be [SCALar] or ARRay.
Replace <meter_fn> with the required measurement function.
Command
FETCh[:SCALar][:<meter_fn>]? [<expected_value>]
FETCh:ARRay[:<meter_fn>]? [<expected_value>]
Parameter
<expected_value> can be omitted, specifies the expected measured data value. If specified explicitly, an appropriate range is selected. If omitted or DEF is specified, auto range is selected.
Response
Returns the measured data in the NR3 form in response to FETC?.
Returns the measured data in the NR3, NR3... form in response to FETC:ARR?.
Queries the measured data after starting a new measurement operation. READ? is equivalent to combining the INIT command and FETC? query.
The second level node can be [SCALar] or ARRay.
Replace <meter_fn> with the required measurement function.
Command
READ[:SCALar][:<meter_fn>]? [<expected_value>]
READ:ARRay[:<meter_fn>]? [<expected_value>]
Parameter
<expected_value> can be omitted, specifies the expected measured data value. If specified explicitly, an appropriate range is selected. If omitted or DEF is specified, auto range is selected.
Response
Returns the measured data in the NR3 form in response to READ?.
Returns the measured data in the NR3, NR3... form in response to READ:ARR?.
Resets a portion of the settings to default, starts the measurement operation, and queries the measured data. MEAS? is equivalent to combining the ABOR, FUNC, CONF command and FETC? query.
The second level node can be [SCALar] or ARRay.
Replace <meter_fn> with the required measurement function.
Command
MEASure[:SCALar]:<meter_fn>? [<expected_value>]
MEASure:ARRay:<meter_fn>? [<expected_value>]
Parameter
<expected_value> can be omitted, specifies the expected measured data value. If specified explicitly, an appropriate range is selected. If omitted or DEF is specified, auto range is selected.
Response
Returns the measured data in the NR3 form in response to MEAS:<meter_fn>?.
Returns the measured data in the NR3, NR3... form in response to MEAS:ARR:<meter_fn>?.
Sets the default unit of the phase angle.
The unit specified by this command is the default unit for the response obtained by the FETC:IMP:PHAS, READ:IMP:PHAS, and MEAS:IMP:PHAS queries.
Command
UNIT:ANGLe {DEG|RAD}
UNIT:ANGLe?
Parameter
Value: | DEG | Set to degree (default) |
RAD | Set to radian |
Table shows the setting that is specified when *RST or *RCL is sent.
Response
Returns the default unit in the CHAR form in response to UNIT:ANGL?.
