To set up the anti-alias filter test
Performance Test only
This test verifies that the Agilent 89410A meets its dynamic range
specification for alias responses. In this test, the 89410A measures the ability
of the low pass anti-alias filter to reject frequencies caused by aliasing. Alias
frequencies occur when the difference of the input signal frequency and the
89410A’s sample rate both fall within the frequency range of interest. Using a
synthesizer/level generator, a signal known to cause an alias frequency is
connected to the 89410A. The 89410A then measures the alias frequency to
determine how well the alias frequency was rejected. This test checks eight
alias frequencies (the ‘’Performance Test Record’’ at the end of this chapter
lists the alias frequencies).
