Freq Resp 100 kHz to 3 GHz Preamp Off Performance Test

This test applies to the following models:

Frequency Response (aka. Flatness) is defined as the amplitude deviation from the reference amplitude at 50 MHz. The complete analyzer Frequency Response is measured with the following tests depending on options:

A “buried power sensor” technique is used to characterize the tracking error of a power splitter in order to avoid the relatively large specified tracking error. This technique reduces the measurement uncertainty to verify the frequency-response specification for the 100 kHz to 3 GHz range. The buried sensor calibration is valid for four hours.
