Adjustments and Correction Constants
RF Output Power Correction Constants (Test 47)
RF Output Power Correction Constants (Test 47)
This procedure adjusts several correction constants that can improve the output power
level accuracy of the internal source. They are related to the power level, power slope,
power slope offset, and the ALC roll-off factors among others.
Analyzer warmup time: 30 minutes.
Required Equipment and Tools
Procedure
1. If you just completed “Sampler Magnitude and Phase Correction Constants (Test 53),”
start at step 8 in this procedure.
2. Press .
3. Press . The default power meter
address is 13. Refer to the power meter manual as required to observe or change its
GPIB address.
4. Press to toggle between the HP/Agilent 438A/437 and 436A
power meters. Choose the appropriate model number. (Use the 438A/437 selection if the
power meter is an E4419B or E4418B.)
NOTE If you are using the 438A power meter, connect the 8482A power sensor to
channel A, and the 8481A power sensor to channel B.
