GPS Option Verification (Option 31)

The following test verifies the operation of the GPS option in the model MS2723B or MS2724B
Spectrum Master.
Required Equipment:
• Spectrum Master: MS2723B or MS2724B
• GPS Antenna, Anritsu 2000-1410
• Anritsu MG3692x Synthesized Signal Generator
• Frequency Reference Symmetricom Rubisource T&M
Setup Procedure:
1. Connect the GPS antenna to the GPS Antenna connector on the MS2723B or MS2724B.
If no fixed GPS antenna is available, the Anritsu 2000-1410 GPS antenna can be used for this test.
Note Ensure that the Anritsu 2000-1410 GPS antenna is in a direct line-of-sight relationship to the
satellites or that the antenna is placed outside with no obstructions.
2. Press the Shift key and then the System (8) key.
3. Press the GPS soft key, then press the GPS On/Off soft key to turn the GPS On.
4. When the GPS fix is acquired, the GPS indicator at the top of the LCD display turns green. The latitude
and the longitude are displayed next to the GPS indicator.
5. After about three minutes, the Reference Source indicator in the lower left-hand corner of the LCD
display will change to GPS High Accuracy.
6. If the GPS fix is acquired using the Anritsu 2000-1410 GPS antenna outside, then bringing the
instrument inside will cause a loss of satellite tracking. A red cross will appear on the green GPS
indicator, and the Reference Source indicator will change to Int Hi Accy.
The following test can be used to verify frequency accuracy to a lesser specification.
