User Manual 3162A/B
Using The Instrument 3-22
gate signal is de-asserted, the output completes the last cycle and resumes
position at a DC level equal to the last point of the waveform.
Gated mode operates on standard waveforms, arbitrary waveforms, and on
sequences of waveforms. Observe the limitations of the gating signal as listed
in the specification section of this manual. To place the Model 3162B in Gated
mode, use the following commands:
INIT:CONT OFF
TRIGger:GATE {OFF | ON}
The default state for the Gated mode is OFF. Turning Gated mode ON
automatically turns Burst mode off.
The query:
TRIGger:GATE?
queries the gate state and returns "0" (OFF) or "1" (ON).
Burst Mode
Burst mode is very similar to Triggered mode with the exception that only one
trigger signal is needed to generate a counted number of output waveforms.
In Burst mode, the output remains at a DC level as long as the TRIG IN signal
from the front panel remains inactive. The trigger input is sensitive to either the
rising edge or the falling edge. Each time a transition at the trigger input
occurs, the Model 3162B generates the number of output cycles that have
been programmed in the burst count parameter. At the end of the burst, the
output resumes position at a DC level equal to the last point of the waveform.
The burst count is programmable from 1 to 10
6
. The default burst value is 1.
Burst mode operates on standard waveforms and arbitrary waveforms. Note
that the Model 3162B cannot operate in Sequence and Burst modes
simultaneously. Observe the limitations of the trigger signal as listed in the
specification section of this manual. To place the Model 3162B in Burst mode,
use the following commands:
INITitiate:CONTinuous OFF
TRIGger:BURSt ON
TRIGger:COUNt <counts>
INIT:CONT OFF places the Model 3162B in a non-continuous mode.
TRIG:BURS ON turns the burst function on. The TRIG:COUN specifies the
number of waveforms output after a qualified trigger signal. To ensure proper
operation, enable Burst mode after setting up the burst parameters. When
Burst mode is enabled, previously programmed trigger or gate modes turn off
automatically.
