Power Reference Oscillator Level Adjustment

Two methods for calibrating the level of the Power Meter reference signal are
provided in this section. Both methods provide acceptable results, and either one
can be used.
Method 1
Equipment Required
Keysight E4418B Power Meter
Keysight 8481A Power Sensor
Keysight 11730A Power Sensor Cable (supplied with 53147A/148A/149A)

test equipment should be powered on for at least 30 minutes prior to
beginning the calibration procedure. This allows the internal temperatures of
the equipment 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.
