mode for the instrument. You can select between continuous, trig-
gered, gated and burst modes. There is no additional panel associ-
ated with continuous mode. If you press one of the other operating
mode options, the 3155 will be updated with the new trigger option
and the Trigger Panel will pop up, allowing adjustments of trigger pa-
rameters.
The SYNC Output group controls SYNC parameters and enables or
disables the SYNC output. The SYNC output is enabled when the
State button is ON. The SYNC Width and Position parameters affect
the 3155 when the BIT validator is selected. In LCOM mode, the
width and the position will have no affect on the SYNC output.
The TTLTrig lines are available on a backplane (P2) connector, The
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 a 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.
The Output group is used for controlling the output state of the 3155.
The button toggles the output ON and OFF.
Besides the grouped buttons and parameters, there are three other
buttons on the right top corner of the panel. These buttons provide
access to the Utility and Modulation Panels. Also, if you press the
Exit button, the program will terminate.
