3. DYNAMIC ACCURACY - 1 MHz
Description
This test checks the dynamic accuracy of the E5071C at 1 MHz. The dynamic
accuracy is tested at 1 MHz for each receiver port at 0, -10, -20, -30, -40, -50,
-60 using step attenuators. The following footnote will be added to the
measurement report to explain why the test does not test points below
-60dBm:
Dynamic Accuracy of a receiver consists of three regions: Compression, Linear,
and Noise & Crosstalk. Measurements below -60dBm 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.
Test equipment
Test Equipment (DSG)
1
1. The DSG (Device Substitution Group) is listed below the equipment description, if
applicable. These devices are required to be mapped in TME to execute a test.
DSGs require either GPIB communication or are important for dynamic measure-
ment uncertainty calculations. N/A refers to required equipment that is not mapped
as DSGs in TME.
