Example
See the SUB example on the preceding page.
SWEEP
The SWEEP command specifies the effective_interval between samples (readings
and the total number of samples taken per trigger event [most measurement
functions] or per trigger arm event (sub-sampling only).
Syntax
SWEEP [effective_interval] [,#_samples]
effective_interval
For sub-sampling (SSAC or SSDC), this parameter specifies the spacing of
samples in the reconstructed waveform (see
measurement functions, this parameter specifies the actual time interval from one
sample to the next. For sub-sampling, the valid range of this parameter is 10E-9
to 6000 seconds with 10 ns increments; for all other measurement functions the
range is (1/maximum reading rate) to 6000 seconds in 100 ns increments.
Power-on effective_interval = 100E-9
Default effective_interval = 20 µs
#_samples
Specifies the number of samples to be taken. The valid range for this parameter is
1 to 1.67E+7.
Power-on #_samples = 1024
Default #_samples = 1024

and the TIMER command. The SWEEP and NRDGS are interchangeable; the
multimeter uses whichever command was executed last in the programming.
Executing the SWEEP command automatically sets the sample event to
TIMER. In the power-on, RESET, or PRESET state, the multimeter uses the
