HPE6432_SetSettlingTime
ViStatus HPE6432_SetSettlingTime (ViSession
instrumentHandle, ViReal64 settlingTime);
Purpose
This function sets the settling time.
Settling time is the period of time the synthesizer waits, following the
switch/blanking time, before producing a Trig Out trigger or a Sync Out
trigger.
This time is in addition to the switch/blanking time. A “settled signal”
implies that the frequency and amplitude that was requested of the
hardware is close but not exact. Typically a “frequency only” change
settled to within a few kHz of the desired frequency takes about 200 us.
This is a combination of the 150 us switch/blanking time and 50 us of
settling time; long switch/blanking time is 350 us.
Changing the 10 dB step attenuator (Option 1E1) adds 20 ms to the
switch/blanking time. The switch/blanking time takes place even when
RF blanking is disabled. RF blanking is enabled when the 10 dB step
attenuator is changed.
After a signal is settled, the synthesizer will accept another Trig In.
However, the synthesizer will not step to the next point in the frequency
list until after waiting the specified dwell time.
Settling time specifies the time between the hardware being set up and
the point in time that the synthesizer generates a Sync Out trigger.
Settling time is used every time a new frequency or power is set up in
the synthesizer.
Factory Preset Value: 50 us
Parameter List
instrumentHandle
Variable Type ViSession
This is the ViSession handle that is obtained from the Initialize
function. The instrumentHandle identifies a particular instrument
session.
settlingTime
Variable Type ViReal64
This parameter specifies the time to allow for output settling.
Range: 0.5 x 10-6 seconds to 32.7675 x 10-3 seconds
