Abs Amp Accy EMI Rcvr Mode 9 kHz to 50 MHz Performance Test

This test applies to the following models:

This test measures the absolute amplitude accuracy versus frequency in EMI Receiver Mode: Discrete (Stepped) Scan. The complete absolute amplitude accuracy in EMI Receiver Mode: Discrete (Stepped) Scan is measured with several tests.

The options of the DUT will determine which tests are run from the list below:

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. The buried sensor calibration is valid for four hours. A 10 dB fixed attenuator is placed between the DUT and the power splitter to improve the match.
