High Level Noise
Measured at 1 kHz IF bandwidth, at default power, with either full reflects or through transmission. RMS. Characteristic performance on MS4645B and
MS4647B with either Option 051, 061, or 062. High level noise magnitude may be degraded to 20 mdB RMS (typical) at particular frequencies due to
receiver residuals.
Noise Floor
Measured at 10 Hz IF Bandwidth with no averaging, and at –10 dBm port power. RMS, no leakage correction applied. Measurement made with a through
line connection, with its effects compensated for. Performance at a
x
and b
x
loops is characteristic.
