How to Measure Fast

Examples:

–Get one measurement: FETCh?

–Get 100 measurements:

FETCh:ARRay?￿100

￿ The number of measurements is defined by the setting of the ARM and TRIG counters. The ARM counter can be set directly by the :CONF and :MEAS commands. The :FETCh:ARRay? query pa- rameter only decides how many measurement results to read out.

READ?

This command simply means to start a measurement or measurement sequence and read data.

This query is identical to:

ABORt;INITiate;FETCh?

This means that the counter starts a mea- surement ( single or array) after it has aborted any previous measurements. It also returns the result.

Examples:

–Start one measurement and fetch result:

READ?

–Start measurements and fetch 100 results:

READ:ARRay?￿100

MEASure?

This query is identical to:

CONFigure;READ?

This means that the command sets up the counter and starts a measurement/mea- surement sequence.

Examples:

–Make a frequency measurement:

MEAS:FREQ?

–Make 100 frequency measurements:

MEAS:ARRay:FREQ?￿(100)

–Make 100 frequency measurements on the A-channel:

MEAS:ARRay:FREQ? (100),(@1)

–Make 100 frequency measurements on the A-channel. The expected frequency to be measured is 10MHz with a resolution of 1 Hz.

MEAS:ARRay:FREQ?

(100),10e6,1,(@1)

MEAS:MEM1?, MEAS:MEM? 10

Memory Recall, Measure and Fetch Result

This command is only for PM6681. Use it when you want to measure several pa- rameters fast, i.e., switch quickly be- tween measurement functions.

MEAS:MEM1? recalls the contents of memory 1 and reads out the result, MEAS:MEM2? recalls the contents of memory two and reads out the result etc.

The equivalent command sequence is

*RCL1;READ?

The allowed range for <N> is 1 to 9. Use the somewhat slower MEAS:MEM- ory?￿N command if you must use mem- ories 10 to 19.
