Performance Checks 8712ET/ES and 8714ET/ES
Test Port Input RF Network Analyzers

Table 1-9 Test Port Input (continued)
1. Noise floor is defined as the RMS value of the trace (in linear
format) for a transmission measurement in CW Frequency
mode, with the RF connectors terminated in loads, output
power set to 0 dBm, and no averaging. The noise floor specifi-
cations and typicals for narrowband detection measurements
assume that an isolation calibration has been performed
using an average factor of 16. For the 8712ES/8714ES, exter-
nal broadband detectors will provide a lower noise floor than
the internal broadband detectors.
