Queries the measured current (A) Each command is different in the following ways.
- FETC? does not wait for the measurement to finish. It queries the most recent measured value when the command is received. If there is no measured value, the measured value is queried after waiting for the completion of a single measurement. If TRIG:ACQ:SOUR is set to BUS, an error is returned.
- READ? starts a new measurement and queries the measured value after waiting for the completion of a single measurement. If TRIG:ACQ:SOUR is set to IMM, measurement starts immediately. If set to BUS, an error is returned. If set to any other value, measurement starts after a trigger is applied.
- MEAS? starts a new measurement after resetting (equivalent to *RST) the settings listed in “Setting Measurement Conditions,” and queries a single measured value.
Returns the current (A) in NR3 format in response to the FETC:CURR?, READ:CURR?, or MEAS:CURR? query.
