Displayed average noise level
Preamp off Reference level ≤ –50 dBm
100 kHz < fc ≤ 1 MHz < –90 dBm
1 MHz < fc ≤ 10 MHz < –110 dBm
10 MHz < fc ≤ 1.5 GHz < –124 dBm < –121 dBm when option IBC or XDM is installed
1.5 GHz < fc ≤ 3 GHz < –117 dBm < –113 dBm when option IBC or XDM is installed

Level measurement error ± 1.5 dB (excluding input VSWR mismatch) 20 to 30 °C, peak detector, preamplifier off,
input signal 0 dBm to –50 dBm, 20 dB input
attenuation, frequency > 1 MHz, auto sweep time,
RBW = 1 kHz, VBW = 1 kHz, trace average on to
reduce noise
± 0.5 dB, Typical
Reference level
Setting range –100 to +20 dBm Steps of 1 dB
Setting resolution
Log scale 0.1 dB
Linear scale 1% of reference level
Accuracy 0 Because reference level affects only the display
not the measurement, it causes no additional
error in measurement results from trace data
