10 Rohde & Schwarz R&S ® ZNB Vector Network Analyzer
Measurement accuracy of the R&S ® ZNB20
This data is valid between +18 °C and +28 °C, provided the temperature has not varied by more than 1 °C after calibration. Validity of
the data is conditional on the use of an R&S ® ZV-Z235 calibration kit. This calibration kit is used to achieve the effective system data
specified below. Frequency points, measurement bandwidth and sweep time have to be identical for measurement and calibration
(no interpolation allowed).
Accuracy of transmission measurements
100 kHz to 1 MHz +5 dB to –35 dB < 0.05 dB or < 0.5°
–35 dB to –50 dB < 0.1 dB or < 1°
–50 dB to –60 dB < 0.3 dB or < 5°
1 MHz to 10 GHz +5 dB to –35 dB < 0.05 dB or < 0.5°
–35 dB to –50 dB < 0.06 dB or < 0.6°
–50 dB to –60 dB < 0.1 dB or < 1°
10 GHz to 20 GHz +5 dB to –35 dB < 0.05 dB or < 0.5°
–35 dB to –50 dB < 0.08 dB or < 0.8°
–50 dB to –60 dB < 0.15 dB or < 1.5°
Specifications are based on a matched DUT, a measurement bandwidth of 10 Hz and a nominal source power of –10 dBm.
