Verification
1 Connect a terminal or computer (set to 9600 baud, 8 data bits, 1 stop
bit, and no parity and no pace) to the rear-panel PORT 1. If you need
assistance in setting the serial parameters, refer to the Getting Started
guide.
2 Press the Return key on the terminal.
Verify that either a SCPI > or E-xxx> prompt is returned. The xxx can
be any number for this test. If E-xxx> is returned, send the *CLS
command to clear the error.
3 Type :SYSTEM:STATUS?, then press Enter (or Return) key.
The terminal screen displays the Receiver Status screen, which is a
complete status report of the Receiver. Without a GPS antenna, most
data will be blank or indicating that the instrument is in “Power-Up”
mode. The FFOM = 3 in the upper right corner indicates that the
Receiver is in power-up mode and frequency outputs are invalid. At
this point, the data at the bottom of the screen lists the results of all
internal self-tests. The HEALTH MONITOR, SelfTest, Int Pwr,
Oven Pwr, OCXO, EFC, and GPS Rcv should all show OK.
4 From the terminal keyboard, type
:PTIME:TCODE? and press Return.
