1. Reduced backreflection accuracy in the last 10 dB of range based on termination effectiveness. Depending
on the measurement setup, measurements with lower levels are possible at reduced accuracy.
2. User-calibration supported.
3. For a typical application, add ±0.4 dB for readings between -60 and -67 dB. Add ±0.8 dB for readings
between - 67 and -72 dB. Add ±1.5 dB for readings between -72 and -75 dB.
4. Following the user-calibration procedure at the recommended interval. For simple reflections, such as flat-
end connectors.
5. Add ±0.1 dB between -70 and -80 dBm.
6. Immediately after performing a dark measurement.
7. Add ±0.1 dB between 0 to 3 dBm and between -35 and -40 dBm.
