Frequency Response (Flatness), Preamp On

Test Limits
Frequency Range
100 kHz to 3.0 GHz
> 3.0 GHz to 7.5 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.
