H Impedance. This menu item sets the external trigger (gate) source input
impedance to either 50 W or 1 MW. Press the Impedance button in the side
menu to select this item.
Use the Sync menu item to select the timing with which the sync signal is
generated to either the Start or End of the waveform or sequence. Each time the
Sync button is pressed, the selection toggles between Start and End. This
setting is the same for CH1 and CH2.
The sync signals have a pulse width of 100 ns and a level of 1.2 V with a 50 W
terminator. These signals are output from the front panel CH1 SYNC output
connector and the rear panel CH2 SYNC OUT connector (Option 02).
H Start. In each operating mode, the sync signal is generated when the trigger
or gate signal is generated. However, In Cont mode, the sync signal can not
be set to Start.
H End. In each operating mode, the sync signal is generated at the end of the
waveform or sequence waveform. In Burst mode, the sync signal is
generated at the end of the burst count.
NOTE. When the Sync setting is switched from Start to End, the sync output is
generated.
