IF Amplitude Ripple (Option B7J) Performance Test
NOTE: This test is to be performed on PSA analyzers with Option B7J only.
This test is a functional test. The IF Amplitude Ripple is measured in order to meet the
EVM specification listed for various Digital Comms personalities. In this test, a CW
signal of fixed amplitude is applied through a power splitter to the input of the PSA and to
a power meter. With the PSA center frequency set to the CW value set by the source, the
source amplitude is adjusted to a reference level, as indicated by the power meter.
The source frequency is then changed to a series of offset frequencies within the span of
interest. At each offset frequency, the source amplitude is adjusted to maintain a constant
reading from the power meter. The amplitude at each offset frequency is measured by the
PSA. The difference between the amplitude at an offset frequency and the amplitude at the
reference frequency is the IF Amplitude Ripple.
