Making Measurements
Measuring Jitter Transfer
Perform Jitter Transfer Calibration
The CALIBRATION should always be carried out with LEVEL |
TERMINATE selected on the RECEIVE JITTER display. |
1If 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.
2If 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.
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.
3If you wish to measure STS-3 electrical jitter transfer, connect IN port to OUT port on the SONET module.
