4.1
Self-Test
When power is applied, it takes several minutes for the computer within the MPC to boot up. It takes
up to 15 minutes for the internal OCXO to warm up to a point where the frequency is stable enough to
track satellites.
up to 15 minutes for the internal OCXO to warm up to a point where the frequency is stable enough to
track satellites.
Once powered and stable, the MPC performs the first phase of self-test functions. If no problems are
detected, the STATUS LED on the front of the MPC will glow green. You can monitor the MPC using
the VFD panel Status menu and/or RXSTATUS log. Self-test status of the internal GPSCard can be
examined via the self-status word in the RANGE and RXSTATUS data logs, refer to Volume 2 of the
OEM4 Users’ Guide.
