Performance Checks 8712ET/ES and 8714ET/ES
Test Port Input RF Network Analyzers
1-66 Service Guide
Table 1-9 Test Port Input (continued)
1. The System Dynamic Range is calculated as the difference between
the receiver noise floor and the minimum of either the source maxi-
mum output (maximum power setting minus output power level
accuracy) or the receiver maximum input. System Dynamic Range
applies to transmission measurements only, since reflection measure-
ments are limited by directivity. The System Dynamic Range for
8714ET/ES 75 analyzers is not a specification for frequencies
>2 GHz; it is a characteristic. For the 8712ES/8714ES, external
broadband detectors will provide more dynamic range than the inter-
nal broadband detectors.
2. Option 1E1 adds a 60 dB step attenuator to the 8712ET/8714ET.
