6. Remove the power sensor and connect the TC-3000C to the mixer.
7. Be sure that the measuring receiver is calibrated in Turned RF mode.
8.Set TC-3000C output frequency and level according to the table below. Set the RF
frequency of the HP 8648C to equal the TC-3000C output frequency minus 70MHz.
At all 0dBm level settings, set the readings on the HP 8902A to the ratio reference
for subsequent measurements by pressing “RATIO” key. At each setting, press
“Start” ( F1 ) on the TC-3000C to begin the test.
9. Record the power in the table for each setting.
