8-88 Command Reference
:READ?
Read one Result
The read function performs new measurements and reads out a measuring result
without reprogramming the counter. Using the :READ? query in conjunction with
the :CONFigure command gives you a measure capability where you can fine tune
the measurement.
If the counter is set up to do an array of measurements, :READ? makes all the
measurements in the array, stores the results in the output buffer, and fetches the
first measuring result. Use FETCh? to fetch other measuring results from the out
-
put buffer. The :READ? query is identical to :ABORt;:INITiate;:FETCh?
Returned format: <data>¿
The format of the returned data is determined by the format commands :FORMat
and FORMat:FIXed.
Example:
SEND®
:CONF:FREQ;:INP:FILT 8 ON;:READ?
This example configures the counter to make a standard frequency measurement
with the 100 kHz filter on. The counter is triggered, and data from the measure
-
ment are read out with the :READ? query.
SEND® :READ?
This makes a new measurement and fetches the result without changing the pro-
gramming of the counter.
Type of command: Aborts all previous measurement commands if *WAI is not used. See
page 8-142.
Complies with standards: SCPI 1991.0, confirmed.
