This topic page applies to the E5071C and E5072A using the Normal Variant test plan.
This test checks the dynamic accuracy of the ENA at 1 MHz. The dynamic accuracy is tested at 1 MHz for each receiver port from –60 dBm to 0 dBm in 10 dB steps for E5071C, and from –100 dBm to 0 dBm in 10 dB steps for E5072A using step attenuators.
For E5071C, the following footnote will be added to the measurement report to explain why the test does not test points below –60 dBm:
Dynamic Accuracy of a receiver consists of three regions: Compression, Linear, and Noise & Crosstalk. Measurements below –60 dBm are simply measuring noise variability in the Noise & Crosstalk region rather than the true linearity of the receiver! Since the receiver is linear by design at these lower levels, there is no need to measure linearity below this threshold. Making measurements above this threshold and below the compression region are sufficient to warrant linearity performance of a receiver.

Due to the complexity of the ENA family of analyzers, only a single representative model will be shown. |
