Option Verification 4-5 Option 31, GPS Verification
S3xxE MM PN: 10580-00253 Rev. J 4-7
2. Verify that the S3xxE is in the Power Meter mode and preset the unit.
3. Set the S3xxE span to 3MHz.
4. Set the S3xxE center frequency to 50 MHz.
5. Adjust the MG3692A/B power so that the power meter sensor B matches the sensor B value shown in the
Table A-18.
6. Record the reading on the S3xxE display in Table A-19, “Option 29, Internal Power Meter Accuracy
Verification” on page A-14.
7. Repeat Step 4 to Step 6 for the next test power level in Table A-19.
8. Repeat Step 4 to Step 6 for the next test frequency in Table A-19.
4-5 Option 31, GPS Verification
This test verifies the GPS option on the S3xxE Site Master is functional.
Frequency Accuracy Verification (Only for models S332E and S362E)
The test in this section verifies the Spectrum Analyzer Frequency Accuracy with GPS, Option 31, of the S332E
and S362E in Spectrum Analyzer mode.
Equipment Required
• Anritsu MG3692X Synthesized Signal Source
• 10 MHz Reference Standard
• Anritsu 34RKNF50 50 ohm Adapter
• Anritsu 15NN50-1.5C RF Coaxial Cable
• Anritsu 2000-1528-R GPS Antenna
Procedure
1. Connect the GPS antenna to the GPS Antenna connector on the S332E or S362E. On the S332E or S362E,
change the mode to Spectrum Analyzer and preset the unit.
2. Press the Shift key and then the System 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 will turn green.
5. The latitude and the longitude will also be displayed next to the GPS indicator.
6. Wait for about three minutes after the Reference Source indicator in the lower left hand corner of the
LCD display has changed to GPS High Accuracy.
Note
If a fixed GPS antenna is not available, the Anritsu 2000-1528-R GPS antenna can be used for this
test.
Confirm that the Anritsu 2000-1528-R GPS antenna is in direct line-of-sight relationship to the
satellites by placing the antenna outside without any obstructions.
Note
If GPS fix is acquired using the Anritsu 2000-1528-R GPS antenna placed outside, bringing the
instrument inside will lose 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 will verify frequency
accuracy to a lesser specification.
