Initial S/W Revision Prior to A.02.00
Gate Source
The menus under the Gate Source key are the same as those under the Trigger key, with the exception that
neither Free Run nor Video are available as Gate Source selections. However, a different SCPI command
is used to select the Gate Source (see table below) because you may independently set the Gate Source
and the Trigger Source.
Any changes to the settings in the setup menus under each Gate Source selection key (for example:
Trigger Level, Trigger Delay, etc.) also affect the corresponding settings under the Trigger menu keys. The
SCPI commands used for these are the same for Trigger and Gate, since there is only one setting which
affects both Gate and Trigger. Example: to set the Trigger Level for External 1 you use the command
:TRIG:EXT1:LEV regardless of whether you are using External 1 as a Trigger Source or a Gate Source.

Dependencies In some models, there is no second External input. In these models, the External 2 key is blanked and
the EXTernal2 parameter will generate a “Hardware missing; Not available for this model number”
error.
