Querying measured values
DATA:R?, FETC?, READ?, and MEAS? are used to query the measurement results. Each command is different in the following ways.
- DATA:R? queries measured values in chronological order. The queried measurement values are deleted from the data logger.
- 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.

| FETC:ETIM? READ:ETIM? MEAS:ETIM? |
Queries the elapsed time (s) at a single point |
| FETC:POW? READ:POW? MEAS:POW? |
Queries the power (W) at a single point |
| FETC:VOLT? READ:VOLT? MEAS:VOLT? |

Setting Measuring Conditions
| TRIG:ACQ:COUN | Sets the number of times measurement values are to be recorded |
|---|---|
| TRIG:ACQ:DEL | Sets the delay time for applying measurement triggers |
| TRIG:ACQ:INT:STAT | Sets whether to measure at intervals when TRIG:ACQ:COUN is 2 or higher |
| TRIG:ACQ:INT:TIME | Sets the measurement interval time when TRIG:ACQ:INT:STAT is set to ON |
| TRIG:ACQ:SOUR | Sets the measurement trigger source |
| SENS:APER | Sets the measurement time |
