SUB name
Subprogram. Stores a series of commands as a
subprogram and assigns the subprogram name.
name: A subprogram name may contain up to 10
characters. The name can be alpha,
alphanumeric, or an integer in the range of 0 to
127.
Power-on name = none.
Default name = none: parameter required.
SUBEND
Subprogram End. Signals the end of a
subprogram.
SWEEP [effective_interval][,#_samples]
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).
effective_interval: For sub-sampling (SSAC or
SSDC), this parameter specifies the spacing or
samples in the reconstructed waveform. For all
other 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: for all
other measurement functions the range is (1/
maximum reading rate) to 6000 seconds.
Power-on effective_interval = 100E-9
Default effective_interval = 20 μs
