Installation

Test 2. AM Accuracy

Description

The E6432A microwave synthesizer is configured for linear AM and a

spectrum analyzer is used to measure sidebands. An external function

generator drives the E6432A AM input. The test is performed at carrier

frequencies of 10 MHz and 20 GHz with AM depths of 10% and 90%.

Two AM rates are tested at 1 kHz and 100 kHz.

Required Test Equipment

• 33120A function generator

• 8563E spectrum analyzer

•BNC tee

• BNC 50-ohm load

Equipment Setup

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

warranted performance. The E6432A microwave synthesizer must be

connected to an external 10 MHz reference. Ensure that external

10 MHz reference is selected in the Configuration Dialog Box.

7. Connect a BNC tee to the E6432A microwave synthesizer AM input.

8. Connect a 50-ohm load to one port of the BNC tee.

9. Using a BNC cable, connect the 33120A function generator output to

the other port of the BNC tee.

NOTE The E6432A microwave synthesizer AM input impedance is 2 kilohm

and the 33120A requires a 50-ohm load; therefore, a BNC tee and

50-ohm load are used.

10.Use a high frequency 3.5 mm cable to connect the E6432A

microwave synthesizer output to the input of the 8563E spectrum

analyzer.
