Performing Acceptance Test Procedures

Test 2. AM Accuracy

Description This test is used to verify that AM modulation is working correctly.

The Agilent E6432A microwave synthesizer is configured for linear AM and

a spectrum analyzer is used to measure sidebands. The AM output of the

Racal 3153 arbitrary waveform generator drives the Agilent E6432A

microwave synthesizer AM input. The test is performed at carrier

frequencies of 10 MHz and 20 GHz, with AM depth of 100%, and an

AM rate of 10 kHz.

Equipment Required • Agilent E7501A arbitrary analog signal developer

• Agilent 8563E spectrum analyzer

Equipment Setup

NOTE

All test equipment requires a 30 minute warm-up period to ensure warranted

performance. Both the Agilent E7501A arbitrary analog signal developer

and the Agilent 8563E spectrum analyzer need to be connected to a common

10 MHz reference.

When using the Agilent E7501A arbitrary analog signal developer, ensure

that Reference is set to External; the Reference can be selected from the RF

Source Control view.

Step 1. Use a high frequency 3.5 mm cable to connect the Agilent E7501A arbitrary

analog signal developer output to the input of the Agilent 8563E

spectrum analyzer.
