Figure 2-3 Power Linearity Performance Verification Equipment Setup - Keysight Technologies 8481A Operating And Service Manual

– power splitter (11667A-Option 001)
– amplifier
– step attenuators (8494H and 8496H)
– attenuator/switch driver (11713B)
– 50 MHz, 30 dBm attenuator pad (11708A)
Procedure
1 Turn on the signal generator and power meter. Connect the DUT (848xA) to
2 Zero and calibrate the DUT using the reference sensor with the power meter.
3 Connect the power splitter (11667A option 001) to the RF output of the signal
