Measurement function

FETC/ FETC:ARR

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?.


READ/ READ: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?.


MEAS/ MEAS: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>?.


UNIT:ANGL

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?.
