The Microsemi SyncServer S650 GPS Receiver has an IP address set to
192.92.92.2. This allows temporary access to the GPS Receiver Web
Interface by connecting a Ethernet cable between the GPS Receiver rear
panel Port 1 to the Ethernet port on the System side panel used by the UUT
PMU. Access Username is admin and the Password is Microsemi. Do not
change the Username or Password from these default settings. For further
information on the GPS Receiver Web Interface, refer to the GPS Receiver
Operator manual. Any changes to the GPS Receiver configuration might
result in the instrument no longer working correctly in the System.

6135A/PMU System Timing Unit

The 6135A/PMU System Timing Unit (the Timing Unit) is the timing and modulation
control device in the Calibration System. This device is connected to the Server PC, the
6135A System, the GPS Receiver, and the UUT (see Figure 1-3).
When you run a test, the PMUCal Software sends test parameters to the Server PC. The
Server PC then transmits test parameters to the Timing Unit. The Timing Unit uses the
UTC time signal from the GPS Receiver to precisely control the 6135A System output
frequency, voltage, and current to the UUT.
The UUT is directly connected to the outputs on the Input/Output Panel as shown in
Table 1-8.
