Setting Narrow Pulse Mode
For carrier frequency measurements with ‘on durations’ (Figure 5-6) less than
10
µ
s, narrow pulse mode must be set using the command:
[SENSe:]FREQuency:BURSt:GATE:NARRow {OFF|ON}
[SENSe:]FREQuency:BURSt:GATE:NARRow?
(query form)
ON
- enables narrow pulse mode for ‘on durations’ less than 10
µ
s. Automatic
gate set up (
SENSe:FREQuency:BURSt:GATE:AUTO ON
) is always used
when narrow mode is enabled.
OFF
- disables narrow pulse mode. For ‘on durations’ greater than 20
µ
s, nar-
row pulse mode must be disabled.
Following a reset (
*RST
) or instrument preset (
SYSTem:PRESet
or
Preset
key), narrow pulse mode is disabled.
