Test Limits
The frequency response test, with preamplifier on, measures the signal
analyzer’s amplitude error as a function of the tuned frequency. Measurements
are made ranging from 50 MHz to the maximum frequency range of the
preamp. The signal source amplitude is measured with a power meter to
eliminate error due to source flatness. The measured value is normalized to
50 MHz.
