Dear distinguished guests of the forum,
reference to the 8902A specifications especially the FM/PM
and AM accuracy published in the document , i would be
obliged if anyone here can point out the differences in the
said specs compared to the ones published by some accredited
calibration labs using the same instruments.
example , the Freq Modulation accuracy(as stated in the
8902A spec sheet) is given as +2% of reading + 1 digit at
freqs ranges 250kHz - 10MHz at rates 20 Hz -10kHz at
deviation less than 40kHz peak.
But Agilent in its scope
states it at 0.024FM +10Hz peak?
But using the same
instruments , the accuracy should be 2% + 1 digit ,agreed?
Can i rewrite the accuracy as 0.02FM + 10 Hz peak?
How about Amplitude Modulation accuracy then?
specs state +2% of reading + 1 digit at freq range 150kHz
-10MHz at rates 50Hz - 10kHz and depths 5%-99% but again
Agilent scope states it at 0.025 AM + 0.14 %......
it not be 0.02AM + 0.1% only?
I hope someone can help
explain this difference?
