E.3.3 Setting example of Test Conditions - Data Bitrate -
This section describes an example procedure for setting Output Bitrate.
The Bitrate settings apply to the PPG/ED linked to the MUX/DEMUX.
Table E.3.3-1 Setting example of Output Bitrate
Remote Commands Explanation of Commands
:UENT:ID 1;:MOD:ID 3
:OUTP:DATA:BITR 28.0
Wait 10000 ms.
*
Sets the remote command destination to PPG.
Sets the PPG output bit rate to 25G (56G for MUX
output).
Up to 10 seconds are required for the system clock
to stabilize and for completion of phase adjustment
of the Data and Clock input to the MUX.
*: Wait- indicates the recommended wait time for sending the
command. This command is not supported by the MP1800A.
E.3.4 Setting example of Test Conditions - Jitter Input-
This section describes an example procedure for setting Jitter Input.
The recommended Jitter Input setting varies depending on the
measurement conditions.
For Eye Diagram, Eye Margin, and Bathtub measurement:

Send the following remote commands when the MU181500B Jitter
Module is installed.

Remote Commands Explanation of Commands
:USB:ID 7
:MUX:DATA:JINP OFF
:USB:ID 11
:DEM:CLOC:JINP OFF
:DEM:CLOC:BAND QUAT
:UENT:ID 1;:MOD:ID 6
:OUTP:AUX:REFC 1
Sets the remote command destination to MUX.
Sets MUX Jitter Input to OFF.
Sets the remote command destination to DEMUX.
Sets DEMUX Jitter Input to OFF.
Sets DEMUX Clock Input to Quarter Rate.*
The DEMUX Ext Clk Input and Jitter Module
Reference Clock Output must be connected using a
coaxial cable.
Sets the remote command destination to Jitter
Module.
Sets Reference Clock to 1/1 clock output.
*: Sets the argument as shown below depending on the measurement
bit rate.
60 Gbps < Bitrate ≤ 64 Gbps 1/8 Clock Rate(EIGH)
