:ACQuisition :APERture

￿«<Decimal value > MINMAX»

Set the Measurement Time

Sets the gate time for one measurement.

Parameters: <decimal value> is 0.8E–6, 1.6E–6, 3.2E–6, 6.4E–6, or 12.8E–6 and 50E–6 to 400s.

MIN gives 800 ns and MAX gives 400 s.

Measurement Times of 800 ns to 12.8 ￿s work in :FREQ:CW, FREQ:BURST, :FREQ:PRF, ￿ :FREQ:RAT and :PERiod. If one of these short times is selected when the counter makes other measurements, it will use 50 ￿s.

￿If you want to switch between Average and Single measurements, use the :AV- ERage:STATe ￿ ONOFF in the Sense Subsystem.

When Single is selected and an array measurement is done, the Measurement Time, set by :Acquisition:APERture, sets the time between the measure- ments in the array. This means that if you want a very high speed, you must set :AVER:STATE ￿ OFF and :ACQ:APER ￿ MIN.

:ACQuisition :APERture

￿«<Decimal value > MIN MAX»

Set the Measurement Time

Sets the gate time for one measurement.

Measurement Times of 80 to 1280 ns work in :FREQ:CW, FREQ:BURST, :FREQ:PRF, ￿ :FREQ:RAT and :PERiod. If one of these short times is selected when the counter makes other measurements, it will use 5 ￿s.

￿If you want to switch between Average and Single measurements, use the :AV- ERage:STATe￿ ONOFF in the Sense Subsystem.

When Single is selected and an array measurement is done, the Measurement Time, set by :Acquisition:APERture, sets the time between the measure- ments in the array. This means that if you want a very high speed, you must set :AVER:STATE ￿ OFF and :ACQ:APER ￿ MIN.

Parameters: <decimal value> is 80, 160, 320, 640, 1280 ns and 20 ￿s to 400 s. MIN gives 80 ns and MAX gives 400 s.
