28 E4416A/E4417A Power Meters Service Guide
Instrument Accuracy (Average Path) Test
Specification
Description
The power meter accuracy is verified for various power inputs. There are two
different methods described in this section that can be used to perform this
test. One of these methods has a higher measurement uncertainty value
associated with it.
Test Procedure 1
Equipment
• Range calibrator: Agilent 11683A.
• Power sensor cable: Agilent E9288A.
Electrical Characteristics Performance Limits (maximum)
Accuracy ±0.5% or 0.02 dB
*
* This performance limit does not include the corresponding sensor power linearity specification.
The measurement uncertainty of this test procedure is relatively high at power levels of
30 μW and below, as it uses a standard 11683A Range Calibrator. As such, this test
procedure should be used for indication only.
