Verifying Performance
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
Pulse Demodulation
Equipment Required
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.
