3.6.2 MODE Key
Selects the output mode: CONT (Continuous), TRIG (Triggered), GATE (Gated), and BRST (Burst).
To select the output mode, press MODE, then press the function key that corresponds to the desired Mode menu
option, as shown:
Mode Menu
F1: CONT - (Continuous) - Selects continuous output.
F2: TRIG/BRST - (Triggered) - Triggers one output cycle of the selected waveform for each trigger event.
- (Burst) - Triggers output N cycles for each trigger event, where N ranges from 2 to 999,999.
F3: GATE - (Gated) - Triggers output cycles as long as the trigger source asserts the gate signal.
F4: PHASE - (not available in PULSE and ARB mode) Selects the start phase of the signal in non-continuous
modes. The range is from -360
˚ to +360˚, with a 0.1˚ resolution. In PHASE mode F2: SET-ZERO
sets the phase reference to zero when few instruments are connected to the same external reference
and need to be synchronized with different phase relations.
After selecting the TRIG , GATE or BURST menu, the trigger source menu is available:
Trigger Menu
F1: MAN - Selects manual as the trigger source. To trigger the waveform generator,
press this MAN TRIG again.
F2: INT - Selects the internal trigger generator as the trigger source. Change the
internal trigger rate displayed with the rotary input knob.
F3: EXT - Selects the external trigger signal as the trigger source. The trigger source
is supplied through the TRIG IN connector.
F4: NBRST - Selects the number of burst pulses to be output with each trigger. The N can be changed from 2 to
999,999.
