Power linearity performance verification

The power linearity performance verification measures the relative linearity error
of the E-Series E9320 power sensor. All measurements are performed at 50 MHz.
The reference power level for the linearity measurement is 0 dBm for the E9321A,
E9322A, E9323A, E9325A, E9326A, and E9327A models.
This performance verification requires the following equipment:
– signal generator (N5182A)
– reference sensor (E4412A)
– power meter (E4416/7A)
– power splitter (11667A)
– amplifier
– step attenuators (8494H and 8496H)
– attenuator/switch driver (11713B)

Procedure
1 Turn on the signal generator and power meter (with the reference sensor
2 Zero and calibrate both the DUT and reference sensor.
3 Connect the power splitter (11667A) to the RF output of the signal generator
