•
TRIG CH x This selection is used for the five channel option to determine
whether the trigger comes out of channel 1 or channel 5.
•
TIMEDIV This selection is used to cycle through the settings. “OFF” shuts off
the external trigger and disables the skew function. “/1” allows the trigger to
appear on every 10th pulse. “/100” allows the trigger to appear on each pulse.
“/10” allows the trigger to appear on every 100th pulse. Note that skew only
works with the “/1” selection.
•
MODE Indicates you are in “pulse” mode. Use the softkey to change modes and
open menus for other oscilloscope calibration modes.

If you have the 5-channel option, the following describes each item in the TRIG menu:
•
TRIG CH Allows you to select either Channel 5 (C5) or Channel 1 (C1) as the
external trigger channel, with C5 being the default. When you select one channel as
an external trigger, the other channel becomes a source.
•
TIMEDIV Allows you to select the trigger settings, with ”off” being the default.
When the trigger is on, the instrument does not allow the signal output and trigger
output to be on the same output. If you change the external trigger from C5 to C1 and
select a trigger setting other than “off,” the Calibrator automatically changes the
source from C1 to C2. This change prevents a conflict between the external trigger
and the source.
If you change the external trigger from C1 to C5 and select a trigger setting other
than “off,” the Calibrator automatically changes the source from C5 to C1.
