Setting Narrow Pulse Mode
For carrier frequency measurements with ‘on durations’ (Figure 5-6) less than
10 µs, 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 µs. 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 µs, nar-
row pulse mode must be disabled.
Following a reset (*RST) or instrument preset (SYSTem:PRESet or Preset
key), narrow pulse mode is disabled.
