Display Scale Switching Uncertainty
Switching between Linear and Log 0 dBa

a. Because Log/Lin and Log Scale Switching affect only the display, not the measurement, they

cause no additional error in measurement results from trace data or markers.

Log-Linear Fidelity (relative to the
reference condition of −25 dBm input
through the 10 dB attenuation, or
−35 dBm at the input mixer)
Input mixer leveldLinearity
−80 dBm ≤ ML ≤ −10 dBm ±0.15 dB
ML < −80 dBm ±0.25 dB
Relative FidelityeApplies for mixer leveld range from −10
to −80 dBm, mechanical attenuator only,
preamp off, and dither on.
