MPA units that have the revised MCH module can be configured for a variety of Internal
and External clock in/out references, via the Clock in/out port.
The second revision MCH cards have been available since October 2015, and have
an RJ-48 connector labeled Clock , as well as a CLK status LED.
The Chassis Clock setting is used to configure the timing source for all test ports in the
MPA chassis to the specified External-clock or to the Internal-clock, with various clock-
out options. Also, each test port in the chassis can independently use a
recovered/looped timing mode.
If the selected External clock option is not available, then the transmitted signals
default to the Internal-clock.
To set the chassis clock:
1. Both the
Processor’s
IP Address and the
MCH’s
IP Address must be known,
and properly configured if the system is connected to a corporate network.
a. See Configuring the MCH's Ethernet Port for more information.
2.
Connect an External clock reference to the MCH module’s RJ-48
Clock port.
3. Select System and choose Misc .
4. Select the MCH IP Address
button and enter MCH’s IP Address.
a.
This setting does not change the MCH’s IP Address. This is simply an
input used to tell the processor what the MCH’s IP Address is.
b. Changes to the Chassis Clock setting are sent to the MCH module via the
Ethernet connection.
