VXI ECLTrg Functions
Input Functions
- reference frequency in trigger source in (i.e. the
waveform clock) start arm in (enables waveform
clock)
Output Functions
- marker bits stored with arbitrary waveforms
- reference frequency
- waveform clock
- a pulse indicating each waveform repetition
- a level change at the start and the end of each burst
of waveform repetitions
- frequency change
- phase change
VXI TTLTrg Functions
Input Functions
- trigger source (i.e., the waveform clock)
- waveform clock gate/FSK Input
- start arm (enables waveform clock)
- waveform clock stop (causes the current waveform
repetition to be the last)
- sweep arm (starts sweep or frequency list)
- sweep trigger (go to next point in sweep or
frequency list)
Output Functions
- none
