General Information
Specifications
The HP 37717C must be connected
back to back in order to perform a
calibration cycle before making a Jitter
Transfer measurement.
The HP 37717C must have been
switched on for 1 hour before starting a
calibration cycle.
The climatic conditions must remain
stable from switch-on to end of
measurement.
It is recommended that the maximum
test period (start of calibration to end of
measurement) does not exceed 90
minutes.
Test Period = Delay Time + Dwell
Time + 5 Seconds X Number of Points
X 2 (Calibration + Measurement).

Meets ITU O.171 Table 4.
These ranges cover the measurements
range specified in O.171, Table3/O.171.
Note that the receiver will be able to
handle transients of up to 24UI(peak)
without losing lock, although the
measurement will be out of range.
On Losing Lock the Jitter Loss LED is
illuminated. If Lock is maintained but
the measurement is out of range then a
Status Message "Jitter Out of Range" is
displayed on the Status Line.
