Fluke Wavetek-Datron 395 - Pulse Train

Sync Out
Use the knob or keypad to enter the "program" value. For pulse periods <655 !ts, the
delay is programmable between -600
flS and +600 !ts. For pulse periods >655 !ts, the
width is programmable between -99.9% and +99.9%
of the pulse period. The screen
dispIays the actual delay value which may be different from the programmed value
based on the overall pulse parameters.
Press F4, "exit," to return to the Standard Waveformscreen. The "next" key, F8, returns
to the Pulse Period screen.
4.4.12.12 Pulse Train
A pulse train can contain up to ten pulses. Bach pulse (index) can have its own rise/fall
time, delay/width, and pulse level. Position
of the pulses in the pattern are determined
by their delay and not the index numberbecause the pulse pattern is relative to the Sync
signal.
l'rom the Standard Waveform screen, select "pulse train" to generale a
puls~ Ilain setup
via "pulse train setup
