Test 5: Power Meter Reference Level

Two methods for verifying the level of the Power Meter reference signal are
provided in this section. Both methods provide acceptable results, and either one
can be used.

Power Meter Reference Level: Method 1

Equipment Required
Keysight E4418B Power Meter
Keysight 8481A Power Sensor
Keysight 11730A Power Sensor Cable (supplied with 53147A/48A/49A)
– To ensure that the test results are valid, the Keysight 53147A/48A/49A and

to stabilize.
one level removed from NIST (National Institute of Standards and
Technology). If the E4418B Power Meter's calibration is more than one level
removed from NIST, the test results will be invalid.
