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 5- 1). For Agilent E- Series, 8480 Series and N8480 Series power
sensors, this specification applies when zeroing is performed with the
sensor input disconnected from the POWER REF.
