Median Gain and Frequency Response Flatness

Specifications (at 25 °C ±5 °C)
Median gain over 300 kHz to 1 GHz
Frequency response flatness (relative to med ian gain)
300 kHz to 1 GHz
1 GHz to 3 GHz
Description
This test procedure performs a response calibration on the analyzer and then
measures the gain of the probe over frequency. Maximum and minimum gains in
two different frequency bands are used to determine the probe performance.
Procedure
1 Preset the analyzer using the [PRESET] hardkey.
2 Set the frequency sweep range for 300 kHz to 3 GHz.
3 Set the analyzer for a transmission (S21) measurement.
