82 Digitizer Command Reference
•
Reset (*RST) condition: TIMer source with 0.0000013 second sampling
SAMPle:SOURce? command queries the present source setting for the sample
signal. The returned string is either HOLD, TIMer, TTLT0-7 or EXT.
SAMPle:TIMer <interval> | MIN | MAX command sets the time interval for
each sample event when the sample source is TIMer. Measurements are made on the
input signal at this rate. This interval is common to all channels for sample source
TIMer.

Name
interval
** See SENSe:ROSC:EXT:FREQ <freq> command
•
The sample interval specified by the period parameter must be a multiple of
the reference oscillator period. The specified time, if not a correct multiple of
the reference oscillator period, will be rounded to the nearest value that can be
attained. For SAMPle:SOURce INTernal, if not a correct multiple of 1E-7, it
will be rounded to the nearest value that can be attained by the internal clock.
•
Executable when initiated: No
•
Coupled command: Yes, the value is changed to the nearest possible value if
an external reference is specified.
Reset (*RST) condition: 0.0000013 (1.3 µS)

SAMPle:TIMer? [MIN | MAX] command queries the sample interval when the
sample source is TIMer.
SAMPle;SOURce command. TTL sources may conflict
with the output subsystem. Specifying a TTL source will
force the output to be disabled. See OUTPut command.
