BBIQ Input Frequency Response (Option BBA only)

BBIQ Input Frequency Response
(Option BBA only)
Test Limits
Frequency Range
250 kHz to 10 MHz (Standard)
250 kHz to 25 MHz (Option B25)
250 kHz to 40 MHz (Option S40 or SU1)
This procedure tests the amplitude response of each of the BBIQ inputs versus
frequency. For each input, a reference measurement is made at 250 kHz and
then subsequent measurements are made at several frequencies up to the
maximum IQ bandwidth. The amplitude difference between the measurement
at 250 kHz and subsequent frequencies is calculated and compared to the test
limit.
