B.35 [SOURce:]LIST:TRIGger COMMAND
LIST:TRIG
Syntax: Short Form: LIST:TRIG
Long Form: LIST:TRIGger
where:
= programmed current (Amps) for current list, or programmed voltage (Volts) for voltage list.
Description: Similar to LIST:VOLT or LIST:CURR, except also allows Output Off flag of External Protection Port to be
used to trigger an external device. In addition to setting the output to the specified (for duration estab-
lished by LIST:SET:TRIG), causes the Output Off flag transistor (EXT_E, pin 5, and EXT_C, pin 6, of the External
Protection port) to be set to the state (on or off) for the duration set by the LIST:SET:TRIG command.
If the trigger duration is not established by the LIST:SET:TRIG command, a -221 “Settings conflict” error results.
This command must be preceded by LIST:CURR or LIST:VOLT command, otherwise a -221 “Settings conflict” error
results. The entries on the dwell list must match the values on the current or voltage list, otherwise a -226 “Lists Not
Same Length” error results. (See Figure B-2B.)
B.34.1 [SOURce:]LIST:WAIT:HIGH COMMAND
LIST:WAIT:HIGH
Syntax: Short Form: LIST:WAIT:HIGH value
Long Form: LIST:WAIT:HIGH value
where:
= programmed current (Amps) for current list, or programmed voltage (Volts) for voltage list.
Description: Waits for the trigger input to go high before advancing to next step. When the command is executed the out-
put is immediately set to the . Pins 1 (GND) and 3 of the Trigger Port are used as the input trigger. If the
trigger input is high (TTL logic 1 or open circuit) and a wait time has been established by LIST:SET:WAIT, the step
is immediately skipped. If the trigger input is low (TTL logic 0 or short-circuit), the unit will proceed to the next step
when either a) the trigger input goes high or b) the wait time expires (non-zero wait values only), whichever comes
first. If the wait time is 0, the unit must wait until the trigger input goes high before proceeding to the next step.
In all cases, the trigger input must be high or low for at least 4 milliseconds to be considered stable. This 4 millisec-
ond delay provides a noise filter to insure only a level causes the output change.
This command must be preceded by LIST:CURR or LIST:VOLT command, otherwise a -221 “Settings Conflict”
error results. The entries of the dwell list must match the values in the current or voltage list, otherwise a -236 “Lists
Unbalanced” error results. (See Figures B-2A and B-2B.)
B.34.2 [SOURce:]LIST:WAIT:LEDGe COMMAND
LIST:WAIT:LEDG
Syntax: Short Form: LIST:WAIT:LEDG value
Long Form: LIST:WAIT:LEDGe value
where:
= programmed current (Amps) for current list, or programmed voltage (Volts) for voltage list.
Description: Waits for the leading edge of the trigger input to go low before proceeding to the next step. If the trigger
input is already low, the signal must go high then low for the leading edge to be accepted. When the command is
executed the output is immediately set to the . Pins 1 (GND) and 3 of the Trigger Port are used as the input
trigger. If the trigger input goes from high to low (TTL logic 0 or short-circuit) and a wait time has been established
by LIST:SET:WAIT, the unit will proceed to the next step when either a) the trigger input goes low or b) the wait time
expires (non-zero wait values only), whichever comes first. If the wait time is 0, the unit must wait until the trigger
input goes from high to low before proceeding to the next step.
This command must be preceded by LIST:CURR or LIST:VOLT command, otherwise a -221 “Settings Conflict”
error results. The entries of the dwell list must match the values in the current or voltage list, otherwise a -236 “Lists
Unbalanced” error results. (See Figure B-2C.)
