Width This menu item allows you to view and modify the width of the pulse that
appears at the RF out-put connector when an appropriate triggering signal is applied
to the rear-panel PULSE IN/PM TRIG IN connector.
NOTE: The same width parameter setting gets used for all three internal pulse
modulation modes (continuous, triggered, and gated); it is not set and stored
separately for each of these modes.
Sync Out Delay Determines the amount of delay that occurs between the leading edge
of the video pulse at the PULSE OUT connector and the leading edge of the sync pulse
at the PM SYNC OUT connector.
Trigger Polarity Allows you to view and choose the edge of the TTL pulsed input signal
applied to the PULSE IN/PM TRIG IN connector that is used to trigger an RF pulse at
the RF output connector. Determines whether the rising edge or falling edge of the
pulse at the PULSE IN/ PM TRIG IN connector will trigger an RF pulse at the output.
The available selections are:
Rising Edge
Falling Edge
