Effective system data
This data is valid between +18 °C and +28 °C, provided the temperature has not varied by more than 1 °C after calibration. The data is
based on a measurement bandwidth of 10 Hz and system error calibration with an R&S
® ZV-Z270 calibration kit. Frequency points,
measurement bandwidth and sweep time have to be identical for measurement and calibration (no interpolation allowed).
