Hi Magnus...
 
 
Appreciate any help!
 
I participate in the ARRL Frequency Measuring Test,
and I would like to automate the measuring process.
 
I have two frequencies, A and B...
 
A is a GPS locked HP 3336B set to 455,000.000 Hz
 
I use the 3336B instead of the 455,000Hz BFO
signal from my GPS locked Racal receiver so
that I can measure AM stations without the
annoying beat note.  ;-)
 
B is an IF signal which should appear between
455,000.000Hz and 455,001.000 Hz
 
I would like the 5372A to calculate the B minus A
delta, over a manually started and automatically
stopped measurement period of 110 seconds.
 
I would like a delta resolution of 0.001Hz to be
developed by the box.
 
Now, there will be doppler.  I want the box
to analyze and give me a best statistical guess
for the B minus A delta.
 
BTW the B minus A delta will be added to the
frequency of my Racal receiver to give me the
best "guess" as to the correct frequency of the
target signal.
 
The Racal reads out to the Hz, and I am able to
accurately determine if the Racal is tuned above
or below the "target" frequency.
 
I will be tuned below the "target" and within
1 Hz of the "target."
 
I assume I will be in the one frequency mode.
 
Can the box give me the desired resolution?
 
What sampling period would be the best to use?
 
What statistical result would I use as my delta?
 
Appreciate your help.  My head is spinning whenever I
get into the operating manual!
 
TNX...
