Preliminary Test Setup
If you have not connected the GPS antenna to the Receiver, perform
the following preliminary procedure in this section.
If you have already connected the GPS antenna to the Receiver, go to
the next subsection titled “Test 1: 10 MHz Frequency Accuracy and
1 PPS Jitter (Locked to GPS).”
1 Connect the antenna system to the rear-panel ANTENNA Type-N
connector of the Receiver as described in the instructions given in the
section titled “Preparing the GPS Receiver for Use” in Chapter 1, of the
58503B/59551A Getting Started Guide.
NOTE Do not apply power to the Receiver unless a fully operational antenna
system is connected to the ANTENNA input connector. Power applied
with no antenna input or a non-functioning antenna will initiate an
extended search process that may increase time to reach GPS lock. You
can halt the extended search by disconnecting and reconnecting
(cycling) the external supply voltage to the Receiver (you may need to
leave power disconnected for greater than five seconds).
2 Connect the Receiver to a suitable power source. (If needed, refer to the
subsection titled “To Connect Power” in Chapter 1 of the
58503B/59551A Getting Started Guide.)
3 The Receiver will perform a self-test of internal components. Verify
that after 15 seconds the Power indicator illuminates and the Alarm
indicator is off. This ensures that all internal components and
connections are functioning.
