ENTRY DESCRIPTION
higher than 200,000 are displayed as a floating point number
(2E+05). The display has insufficient characters to display the
entire mantissa so entering values above 2E+05 from the
keyboard is not recommended.
TRIG SOURCE Indicates the trigger source for transient system. Available
trigger sources are:
IMM Immediate mode. The transient is started from
the front panel using the ENTER key.
BUS Bus mode. The transient system is started by a
bus command or a group execute trigger (GET).
EXT External mode. The transient system is started
by a user-provided external TTL trigger signal
on TRIGGER IN.
TRAN STEP Indicates the transient system execution mode. Available
modes are:
AUTO When triggered, the transient system will
automatically execute each list point
sequentially without waiting for a trigger
between list points. This execution is paced by
the dwell time set for each data point.
ONCE When triggered, the transient system will
execute the first list point and wait for a new
trigger once the dwell time expires. This allows
triggered execution of each step in the transient
list.
List parameters:
VOLT Step # Voltage set point
VSLEW Step # Voltage slew rate in V/s
FREQ Step # Frequency set point
FSLEW Step # Frequency slew rate in Hz/s
DWELL Step # Dwell time in seconds.
Range is 0.001 to 900000
TTLT Step # ON: Generates an output trigger pulse at
this list step.
OFF:
No output trigger.
The output trigger is available on the TRIG OUT
on the rear panel. (Aux I/O DB9 connector).
