Test 5: Power Meter Reference Level

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
Agilent E4418B Power Meter
Agilent 8481A Power Sensor
Agilent 11730A Power Sensor Cable (supplied with 53147A/48A/49A)
• To ensure that the test results are valid, the Agilent 53147A/48A/49A
and the test equipment should be powered on for at least 30 minutes
prior to beginning the tests. This allows the internal temperatures of
the equipment to stabilize.
• The calibration of the Agilent E4418B Power Meter must be no more
than 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.
• This test is appropriate for the Agilent 53147A, 53148A, and 53149A.
Connect the Agilent 11730A Power Sensor Cable to the Agilent 8481A
Power Sensor (see Figure 1-8).
