Description
The HP 37717C Jitter Receiver performance is verified using a special internal
instrument calibration routine. This routine is automatic and tests all parameters
except Hit Count and Demodulated Jitter Output.
Hit Count is tested by connecting PDH Signal Out to PDH Signal In with the
transmitted jitter amplitude just exceeding the receiver Hit Threshold and a check
made to ensure the Hit count is within the modulation frequency accuracy limits.
The Demodulated Jitter Output is verified for accuracy by measuring the amplitude
on an oscilloscope.
