2 Connect an Keysight 10503 series cable between the Keysight E9635A adapter
3 Set the Keysight 53150A/51A/52A Frequency Counter to measure frequency
4 Turn on the Keysight 53147A/48A/49A's internal power reference oscillator:
The reference oscillator is normally off. It is turned on automatically during
NOTE
calibration and then turned back off when calibration is complete. Setting PWR
REF in the 53147A/148A/149A's menu to ON turns the power reference
oscillator on, and it remains on until the PWR REF menu setting is returned to
OFF. When you calibrate the Power Meter with PWR REF set to ON, the power
reference oscillator remains on after calibration is complete.
