Instrument Accuracy Test
Specification
Accuracy
1. This performance limit does not include the corresponding sensor power
linearity specification.
Description
The power meter accuracy is verified for various power inputs. There are
two different methods described here that can be used to perform this test,
although one of these methods has a relatively high measurement
uncertainty values associated with it.
Test Procedure 1
Note
Equipment
Agilent E4418B/E4419B Service Guide
Electrical Characteristics
The measurement uncertainty of this test procedure is relatively
high at power levels of 30uW and below, as it uses a standard
11683A Range Calibrator. As such, this test procedure should be
used for indication only.
