In the following setups, cables are designated as solid lines and direct connections are designated as dashed lines.
CXA — N9000A/B with Option C75
This test measures the amplitude error of the analyzer’s 75 ohm input from the reference amplitude at 50 MHz, as a function of frequency.
A “buried power sensor” technique is used to characterize the 5.7 dB loss due to the external minimum loss pad and 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 1 MHz to 1.5 GHz range. The buried sensor calibration is valid for four hours.
The related adjustment for this functional test is Frequency Response (Option C75).
