The soft front panel looks for one or more PXIe-1209 Dual Pulse Generators in the
system. If it finds exactly one, it will display the main panel and start executing as
shown below. If it finds none, then it will ask if you want to run the program in
demonstration mode. If it finds more than one, it will display a list of those found
and let you choose the one you want to communicate with.
Once the instrument has been found and selected, the main panel will be
displayed. It will appear as shown below:
Figure 5-2, RI1209e Main Panel
The PXIe-1209 instrument consists of two independent pulse generators. You can
select which one is being accessed by selecting the “Active PGEN” switch in the
middle of the right hand-side of the main panel.
In order to generate a pulse, you must set the high and low amplitude, the pulse
width, and pulse frequency. You must then push the “Enable” and “Run” buttons.
You may also generate a pulse quickly by clicking on the “Quick Setup” button on
the lower left-hand side of the main panel.
The main panel provides the selection for one of the four main operating modes
provided by the pulse generator:

Single Pulse or Pulse Pair – a single pulse or pulse pair is generated for each
trigger received.

Continuous Cycle – a continuous stream of pulses is generated once a trigger
is received

Burst Count Mode – a set of N pulses is generated for each trigger received.
The number of pulses (burst count) may be set

Follow Trigger – if the voltage input for the selected trigger is below the
programmed threshold voltage, the output will be at the low amplitude voltage.
If the voltage input for the selected trigger is above the programmed threshold
voltage, the output will be at the high amplitude voltage.
