5. Set each of the rf signal generators to provide a power level of –22 dBm
and turn RF On.
a. Set the first generator output frequency to 2.1295 GHz, and the second
generator output frequency to 2.1305 GHz.
b. Set the RSA5100B Function to Normal (Setup > Settings > Traces >
Function > Normal).
c. Set the RSA5100B Center frequency to 2.1295 GHz. Press the Peak key
on the Markers control bar. Adjust the first generator output level for a
marker reading of –25.0 dBm. Record this as carrier #1.
d. Set the RSA5100B Center frequency to 2.1305 GHz. Press the Peak key
on the Markers control bar. Adjust the second generator output level for a
marker reading of –25.0. This is carrier amplitude #2.
6. Set the RSA5100B Function to Averaging (Setup > Settings > Traces >
Function>Avg(VRMS)).
7. Set the RTSA center frequency to 2.1285 GHz. After averaging has
completed, press the Peak key on the Markers control bar and read the
amplitude level of the signal displayed at the center of the screen. Record
this as TOI #1.
8. Set the RTSA center frequency to 2.1315 GHz. After averaging has
completed, press the Peak key on the Markers control bar and read the
amplitude level of the signal displayed at the center of the screen. Record
this as TOI #2.
9. Calculate the Third Order Intermodulation Distortion (TOI) using the
following procedure. Record the results in the test record.
a. Record the maximum reading from step 7 or step 8.
b. Record the minimum reading from step 5 c or step 5 d.
c. Calculate the TOI using this equation:
TOI = step a – step b

Path
1. Terminate the RSA5100B RF Input with a 50 Ω terminator.
2. Reset the RSA5100B to factory defaults: select Setup > Preset (Main).
3. Select Tools > Alignments and sel
ect Align Now.
4. Set the RSA5100B:
