Accuracy

Instrumentation
Absolute: ±0.02 dB (Logarithmic) or ±0.5% (Linear). (Refer to the power
sensor linearity specification in your power sensor manual to assess
overall system accuracy.)
Relative: ±0.04 dB (Logarithmic) or ±1.0% (Linear). (Refer to the power
sensor linearity specification in your power sensor manual to assess
overall system accuracy.)
Zero Set (digital settability of zero): Power sensor dependent (refer to
Table 1-1). For Agilent E-series power sensors, this specification applies
when zeroing is performed with the sensor input disconnected from the
POWER REF.
