System Dynamic Range
is defined as the difference between the available power from Port 1 incident on Port 2 in a through line connection and
the noise floor.

The graphs give measurement uncertainty after 12-Term vector error correction. The errors are worst case contributions of residual directivity,
load and source match, frequency response, isolation, network analyzer dynamic accuracy, and connector repeatability.

NOTES: 1. Specifications between the stated frequencies are to be linearly interpolated as typical values.
2. RMS values – compensated for loss in available source power from test port cable connected between Port 1 and Port 2.
3. The specifications for Test Port Characteristics apply when the VNA Universal Test Port Adapters are connected, with or without
phase equal insertables, to the test set ports and calibrated with the appropriate calibration kit at 23°C ±3°C using the SOLT
calibration method with a sliding load to achieve 12-term error correction. (90 min. warm-up time is recommended.)
