Understanding the Tests

clock signal. The option does not have GPIB control so the program cannot verify that the option is operational.

Test A: RF Analyzer Equipment Required
Pulse Demodulation	HP/Agilent 8657A/B Signal Generator
	HP/Agilent 8116A Pulse Generator
	Theory of the Test
	The Pulse generator drives the signal generator to generate Pulsed RF signals at
	various frequencies. The UUT demodulates these signals and the internal
	oscilloscope measures the rise and fall time of the demodulated waveform. This test
	verifies the demodulator rise and fall time specifications.

Things To Check In Case Of Problems

•The oscilloscope measurement functions are used to measure the 10% to 90% rise and fall time. If the demodulated waveform has significant video feedthrough or the oscilloscope cannot trigger the measurements properly, an incorrect measurement may result.

Test B: Spectrum Analyzer (Option 006 only)

Equipment Required

HP/Agilent 8657A/B Signal Generator

Theory of the Test

The signal generator is used to stimulate the UUT spectrum analyzer at various frequencies. At each frequency, the spectrum analyzer is tuned to measure its own image and spurious responses. The level of the signal generator is set to various levels to determine the spectrum analyzer’s log-linearity.

Things To Check In Case Of Problems

•The absolute accuracy of the signal generator causes a significant measurement uncertainty in the log linearity measurements. A more accurate measurement is to reduce the signal level using a precision attenuator. This is an acceptable secondary manual test if the UUT fails the automated test.
