Agilent E7501A Getting Started 2-11
Test 4. Pulse Modulation Level Accuracy
Description The Agilent E6432A microwave synthesizer and the Agilent E7501A
arbitrary analog signal developer is configured for pulse modulation. A
spectrum analyzer is used in zero span to measure the amplitude of the pulse
envelope. This measured value is compared to the CW amplitude with pulse
modulation turned off. Depending on the model of spectrum analyzer used,
the Pulse Repetition Frequency (PRF) may need to be decreased to measure
the pulse.
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.
