2 Performance Tests
38 Keysight 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: Keysight 11683A.
– Power sensor cable: Keysight E9288A.
Electrical Characteristics Performance Limits (maximum)
Accuracy
±0.5% or 0.02 dB
[a]
[a] 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.
