Frequency Response (Flatness), Preamp On
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.
Frequency Range Limit Relative to 50 MHz
100 kHz to 3.6 GHz ±2.0 dB
> 3.6 GHz to 8.4 GHz ±3.0 dB
> 8.4 GHz to 13.6 GHz ±3.5 dB
> 13.6 GHz to 26.5 GHz ±4.0 dB
> 26.5 GHz to 34.5 GHz ±4.5 dB
> 34.5 GHz to 44 GHz ±6.0 dB
