Using The Instrument 3-21

Figure 3-5, WaveCAD Control Panel for Trigger Mode

Triggered Mode

In Triggered 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 a rising edge or a falling edge. Each time a transition at the trigger input
occurs, the Model 3162B generates one complete output waveform.  At the end
of the output cycle, the output resumes position at a DC level equal to the last
point of the waveform.

The Triggered mode operates on standard waveforms and arbitrary waveforms.
Observe the limitations of the trigger signal as listed in the specification section
of this manual. Note that the Model 3162B is limited to trigger frequencies of
18.75 MHz or less. To place the Model 3162B in Triggered mode, use the
following command:

INITitiate:CONTinuous {OFF | ON}

OFF places the instrument in Triggered mode. ON restores continuous
operation.

The query:

INITitiate:CONTinuous?

queries the instrument operating mode parameter and returns "0" (OFF) or "1"
(ON).

Gated Mode

The Model 3162B can be set to operate in Gated mode only after the
INIT:CONT OFF command has been received. The output remains at a DC level
as long as the TRIG IN signal from the front panel remains inactive. The gating
signal can be programmed to be either active high or active low. Each time the
proper level is present at the trigger input connector, the Model 3162B
generates output waveforms as long as the gate signal is present.  When the
