Using The Instrument 3-20
The query:
PULSe:TRANsition?
queries the pulse rise time setting and returns a value in percent.
The command:
PULSe:WIDTh <value>
sets the pulse width as a percentage of the pulse period. For example, if the
pulse period is 100 ms, 20% pulse width equals 20 ms. Pulse width is
measured between the two turning points on the top of the pulse.
The query:
PULSe:WIDTh?
queries the pulse width setting and returns a value in percent.
The command:
PULSe:TRANsition:TRAiling <value>
sets the pulse fall time as a percentage of the pulse period. For example, if the
pulse period is 100 ms, 15% fall time equals 15 ms. Pulse fall time is
measured between the two turning points of the second transition.
The query:
PULSe:TRANsition:TRAiling?
queries the pulse fall time setting and returns a value in percent.
Selecting an
Operating Mode
The Model 3162B offers four operating modes: Continuous, Triggered, Gated
and Burst. The selected waveform is repeated continuously when the
instrument is set to operate in continuous mode. In this mode, the Model
3162B does not require a trigger source to stimulate output cycles. The default
operating mode of the instrument is continuous.
Triggered, Gated, and Burst modes require an external signal to initiate output
cycles. Information on how to trigger gate output a burst of waveforms is given
in the following paragraphs. The WaveCAD Trigger control panel (shown below)
shows a high-level example of selecting the trigger mode.
