Performance Tests
Test 9 - AM Noise and Spurs (RF)
2. Measure and record the DUT power
Make sure the AM detector is connected to the DUT’s output, and that the
HP 3561A is connected to the detector’s output via a Tee connector.
Figure 14-14
Tee Connector Diagram for HP 3561A
Record the DC voltage measured across the AM detector’s output with the
HP 3561A as described in 1 on the previous page.
3. Set up the calibration source
•
Frequency: 1.2 GHz
•
Power: +10 dBm
•
Modulation: OFF
4. Measure and adjust the calibration source power
Connect the AM detector to the calibration source’s output. Adjust the
calibration source’s output power until the voltage measured on the HP
3561A is within ±5% of the DC voltage measured with the detector
connected to the DUT.
