Hi everyone,
This may be a rookie question... I am trying to measure phase noise using Timelab and
Agilent 53230a but I get a "This plot contains xDEV/phase/frequency data only -- no
phase noise or AM noise records". I tried the following settings and other
variations but still get the same result. Can someone point me to how to measure PN with
a 53230a? Thank you very much for your time.
In Time Lab
Measurement: Phase noise
Acquire from HP 53220A/53230a at specified IP address
Data Type: Time Interval (also tried Frequency)
Input Frequency:10e6
Scale Factor 1.0
Bin Density 29
Bin Threshold: 4
Trace History:1
Trace Duration: 10 min
On the Counter
Period
Auto (also tried Continuous)
Have to break it to you, you can't make phase-noise measurements using
TimeLab that way. You either have to have a TimePod or similar to get
the phase-noise record.
The 53230A will just provide you with time-records. You want to use the
time-interval measurement for that.
Cheers,
Magnus
