Frequency Response (Flatness), Preamp On

Test Limits
100 kHz to 3.6 GHz
> 3.6 GHz to 8.4 GHz
> 8.4 GHz to 13.6 GHz
> 13.6 GHz to 26.5 GHz
> 26.5 GHz to 34.5 GHz
> 34.5 GHz to 50 GHz
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.
