Explanation  AUTO: select "Auto" trigger mode. At this point, the RF signal generator meets
the trigger condition at any time and will start the pulse modulation once the
pulse modulation function is turned on.
 EXTernal: select "Ext" trigger mode. At this point, the RF signal generator
receives the external trigger signal input from the [TRIGGER IN] connector at
the rear panel. The instrument starts a pulse modulation each time a TTL pulse
with the specified polarity is received. To specify the polarity of the TTL pulse,
use the
[:SOURce]:PULM:TRIGger:EXTernal:SLOPe command to select "Pos" or
"Neg".
 EGATe: select "Ext Gate" trigger mode. At this point, the RF signal generator
receives the external gated signal input from the [TRIGGER IN] connector at
the rear panel. The instrument starts a pulse modulation within the valid level
range each time a gated signal with the specified polarity is received. To specify
the polarity of the external gated signal, use the
[:SOURce]:PULM:TRIGger:EXTernal:GATE:POLarity command to select
"Normal" or "Inverse".
 KEY: select "Key" trigger mode. At this point, the instrument starts a pulse
modulation each time Key Trig is pressed.
 BUS: select "Bus" trigger mode. At this point, the instrument starts a pulse
modulation each time the
*TRG or :TRIGger:PULSe[:IMMediate] command is
sent.
 When the modulation source is set to "Ext", this command is invalid.
Return Format
The query returns the trigger mode of pulse modulation. For example, EGAT.
Example :PULM:TRIG:MODE EGAT
