Trigger and List Control Keys
The Trigger Control key controls output transient triggers. The List key controls the generation of output
lists. A list can contain up to 100 points, each of which can specify an output change (or transient). Refer
to Chapter 4 of the Programming Guide for more information about programming triggers and lists.
Press this key to access the trigger control menu list.
Display Command Function
INIT:IMMED Initiate the transient trigger sequence immediately.
INIT:CONT <char> Set continuous trigger initiation (ON or OFF).
TRIG:SOUR <char> Select transient trigger source (BUS, EXT, TTLT or
IMM).
DELAY <value> Set trigger delay in seconds.
ABORT Abort all trigger sequences.
SYNC:SOUR <char> Select trigger sync source (PHASE or IMM).
SYNC:PHASE <value> Set synchronous phase reference angle in degrees.

Display Command Function
COUNT <value> Specifies the number of times a list repeats.
DWEL:<index> <value> List of output dwell times.
FREQ:<index> <value> List of output frequencies.
FSLW:<index> <value> List of output frequency slew rates
IPK:<index> <value> List of output peak current limits.
OFFS:<index> <value> List of dc output voltages.
OSLW:<index> <value> Dc offset voltage slew rate list
PHASE:<index> <value> List of output voltage phase angles.
SHAP:<index> <char> List of output waveform shapes.

(SINE, SQUARE or CSIN) CSIN = clipped sine wave
STEP<char> Response of list to triggers (ONCE or AUTO).
TTLT:<index> <value> List of Trigger Out pulses (0=no pulse; 1=pulse).
VOLT:<index> <value> List of ac output voltages.
VSLW:<index> <value> List of output voltage slew rates.
Notes:

User-defined waveshapes will also appear in this list when created.
value = a numeric value
char = a character string parameter
index = a numeric value that represents a list point from 0 to 99

and scroll through the desired list points. EOL is displayed when the
end of the list is reached. When a value is edited, pressing automatically
advances to the next list point.
Pressing truncates or clears the list at the
presently displayed list point.
