Waveforms The Waveform group is used for selecting between waveform types.
Operating Modes The Operating Modes group is used for selecting the active trigger
SYNC Output The SYNC Output group controls SYNC parameters and enables or

The functional groups in the Main Panel are explained below.
The PXA125 provides three types of waveforms: Standard, Arbitrary
and Sequenced. Pressing one of these buttons will cause two
reactions: 1) The PXA125 will change the output waveform to the
selected option and 2) Another panel, associated with the selected
waveform type will be invoked and brought to the front. The default
waveform type is Standard. Therefore, the opening screen has this
panel behind the Main Panel. If you want to change standard
waveform parameters, you can either click on the standard waveform
panel, or select this panel from the Panels bar.
mode for the instrument. You can select between continuous,
triggered, gated and burst modes. There is no additional panel
associated with the continuous mode, but if you press one of the
other operating mode options, the PXA125 will be updated with the
new trigger option and the Trigger Panel will pop up, allowing
adjustments of trigger parameters.
disables the SYNC output. The SYNC output is enabled when the
State button is ON. The SYNC Width and Position parameters will
affect the PXA125 when the BIT validator is selected. In LCOM mode,
the width and the position will have no affect on the SYNC output.
function of the TTLTrig lines is very similar to the SYNC output. Every
time the generator outputs a cycle, it generates a pulse from its front
panel SYNC output connector. The same SYNC signal can be placed
on one of the TTLTrig lines and can be used for triggering other
instruments that have TTLTrig line capabilities. Enable one or more of
these lines by pressing the appropriate buttons
The SYNC parameters have direct effect on the
TTLTrig line thus, by changing SYNC position, or
width you are automatically assigning the same
parameters to the backplane trigger lines.
Output The Output group is used for controlling the output state of the
PXA125. The button toggles the output ON and OFF.
Besides the grouped buttons and parameters, there are three other
