8-62 Command Reference
:MEASure :FREQuency :PRF?
[8 [<exp. val.>[,<res.>]][,<(@«1|2|3|4»)>]]
Pulse Repetition Frequency
Measures the PRF (Pulse Repetition Frequency) of a burst signal.The burst dura
-
tion must be less than 50% of the pulse repetition frequency (PRF).
+
It is better to set up the measurement with the [:SENS]:FUNC “:FREQ:PRF”
command when measuring pulse repetition frequency. This command will allow
you to set a suitable sync delay with the :FREQuency:BURSt:SYNC:PERiod
command.
How to measure bursts is described in detail in the Operators Manual.
Parameters: <exp. val.> is the expected PRF, <res.> is the required resolution.
<(@«1|2|3|4»)> is the measurement channel:
(@1) means input A
(@2) means input B
(@3) means input C (RF-input option)
(@4) means input E (Rear panel arming input)
If you omit the channel, the instrument measures on input A (@1).
The <expected value> and <resolution> are used to calculate the Measurement
Time ([:SENSe]:ACQuisition:APERture). The Sync. Delay is always 10 ms
(default value)
Complies with standards: SCPI 1992.0, confirmed.
