7 Analog Modules Sampler
224 System Reference, January 2001
The timing generator contains the delay counter and delay
vernier. By using them, the timing generator controls the
delay time from when the trigger signal arrives to when
waveform measurement starts.
When you use two channels simultaneously, the sampling
period, start timing, and stop timing of measurement are
the same for the two channels because the timing gener-
ator and trigger input pins are shared.
Sequencer and Waveform Memory
The sequencer controls the storage of sampled and digi-
tized data into the waveform memory. The conditions for
storing digitized data are specified in the sequence
program that is contained in the sequence memory. The
following conditions can be specified in the sequence
program:
• Number of initial discard points
• Waveform memory area where digitized data is stored
• Averaging times
• Sequence instruction that specifies if the measurement
is halted after the sequence on the current line is
completed (HALT instruction) or continued to the next
line (NOP instruction)
When you use two channels simultaneously, the sequence
program is shared between two channels.
