3.8 Chassis Clock
MPA units with the new SCM-210 module can be configured for a variety of Internal and
External clock in/out references, to support the RJ-45
CLK-A In/Out port or the SMA
CLK-B In/Out port.
The Chassis Clock function is used to configure the timing source for all test ports in the
chassis to the specified External-clock or an Internal-clock, with various clock-out options.
Also, each test port in the chassis can independently use a recovered/looped timing mode.
By default, the transmitted signals default to an Internal clock.
To set the chassis clock:
1. Connect an External clock reference to either the SCM-210’s RJ-48 or SMA Clock
In/Out Ports.
2. Remotely log into to the MPA’s IP Address with the Remote Client software.
3. Select the System tab and choose Misc .
