Measurement operation

FETC / FETC:ARR

FETC? 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.

If <meter_fn> is not specified, the value set in the previous FETC?, READ?, or MEAS:<meter_fn>? command is used.

The second level node can be [SCALar] or ARRay.

Command

FETCh[:SCALar][:<meter_fn>]?

FETCh:ARRay[:<meter_fn>]?

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.

If <meter_fn> is not specified, the value set in the previous FETC?, READ?, or MEAS:<meter_fn>? command is used.

The second level node can be [SCALar] or ARRay.

Command

READ[:SCALar][:<meter_fn>]?

READ:ARRay[:<meter_fn>]?

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:<meter_fn> / MEAS:ARR:<meter_fn>

Resets a portion of the settings to default, starts the measurement operation, and queries the measured data.

The second level node can be [SCALar] or ARRay.

Command

MEASure[:SCALar]:<meter_fn>?

MEASure:ARRay:<meter_fn>?

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>?.
