14 Press MEAS, INPUT PORTS, B, MENU to start measuring the power delivered to
receiver input B.
15 Press CW FREQ, 300, k/m.
16 Write the marker reading, which appears on the analyzer display, in the

17 Repeat Step 15 and Step 16 for the other CW frequencies listed on the
“Performance Test Record.”
18 For each CW frequency, determine which channel input reading shows the
greatest difference:
•power meter versus R
•power meter versus A
•power meter versus B
Refer to the first line for an example listed in the “Performance Test Record .”
Write the greatest difference in the space provided on the “Performance Test
Record.”
