Measuring Jitter
Measuring Jitter
Description: PDH Jitter and PDH error measurements are made simultaneously
when a PDH jitter measurement option is fitted. The measurements are
made on the normal input to the PDH receiver and the interface
selections are the normal PDH Receiver selections.
SDH/SONET Jitter and SDH/SONET error measurements are isolated
individual measurements. The jitter measurement is made on an SDH/
SONET input to the Jitter module.
Cumulative and Short Term results of Jitter Amplitude and Jitter Hits
are provided on the display.
Graph and Text results for Jitter Transfer and Jitter Tolerance are also
provided.
HOW TO: 1 If measuring Jitter on a PDH signal, set up the receive PDH interface
for the error measurements. See “Setting PDH Receive Interface”
page 18 and the receive Jitter interface for jitter range threshold and
filters, see“Setting Jitter Receive Interface” page 23.
2 If measuring Jitter on an SDH/SONET signal, set up the receive Jitter
interface. See “Setting Jitter Receive Interface” page 23.
