Stepped Delay Mode
The stepped delay mode automatically increments or decrements the pulse delay 1 value according to step
delay parameters. Stepped delay mode is only available when the triggering commands
PTG3
(delayed) or
PTG5
(triggered with delay) are specified. The
SD1
command turns on the stepped delay mode. The pulse delay 1
start time can be set using the
SDS
parameter entry command; the delay 1 stop time can be set using the
SDE
parameter entry command. Use the
SDD
parameter entry command to set the step size and the
SDL
parameter
entry command to set the dwell-time-per-step. The
SD0
command turns off the stepped delay mode.
Programming Notes:
Use the
PTR
and
PTF
commands in conjunction with the pulse trigger commands
PTG2
(gated),
PTG4
(triggered), and
PTG5
(triggered with delay) to specify whether the pulse generator is triggered by the rising or
falling edge of the external trigger pulse.
External Pulse Modulation Function
The
XP
command turns on the external pulse modulation function. The
PO
(or
SW0
) command turns off the
pulse modulation function.
