Making Measurements
Measuring Jitter Transfer
HOW TO: Perform Jitter Transfer Calibration
N OT E The CALIBRATION should always be carried out with LEVEL
selected on the display.
1 If DSn Jitter Transfer is required, set up the DSn transmit and receive
interfaces, the receive jitter interface and connect DSn IN to DSn OUT.
See “Setting DSn Transmit Interface” page 2, “Setting DSn Receive
Interface” page 15 and “Setting Jitter Receive Interface” page 18.
2 If OC-3, OC-12 or OC-48 Optical Jitter Transfer is required, set up the
SONET transmit and receive interfaces, the receive jitter interface
and connect the OUT port of the Optical module to the IN port of the
Optical module. See “Setting SONET Transmit Interface” page 4,
“Setting SONET Receive Interface” page 17 and “Setting Jitter
Receive Interface” page 18.
C AU T I O N If OC-3/12/48 SONET Jitter Transfer is required, a 15 dB attenuator
must be connected between the IN and OUT ports of the Optical module.
3 If you wish to measure STS-3 electrical jitter transfer, connect IN port
to OUT port on the SONET module.
