Power level check (high RF power)
The IF OVERLOAD running error message is normal when obtaining these
graphs. A power level of +10 dBm will over drive the 8510XF so you can
see the intermodulation leveling differences. The graphs Figures 5-7 through
5-10 were obtained with the following settings:
1. Factory preset
2. Shorts connected to Ports 1 and 2
3. RF Source leveling: internal (no conversion loss calibration)
4. Disconnect the BNC cable from the millimeter-wave controller ALC
output to the RF Source ALC input.
5. LO Source leveling: system (default)
6. RF Source power: +10 dBm
NOTE Disregard IF OVERLOAD running error message.
