a. Use Preselector: (unchecked)
b. Frequency: 2 GHz
c. Input power: set to +30 dBm.
d. Bandwidth: set to 40 MHz
e. Time span: 100 µs
f. Trigger - Source: Free Run
g. Sweep - Cont.
9. Connect an RF signal to the M9360A RF IN. Set the source to the following frequency and power:
a. Frequency: 2 GHz
b. Power level: -20 dBm
10. On the
Meas
tab:
a. Step the Input Power down in 10 dB increments to 0 dBm.
b. The path is alright if:
i. The noise floor drops approximately 10 dB each time the Input Power level is decreased.
ii. The attenuator clicks as it switches. The attenuator switches when stepping between the levels
displayed in the table in Step 11.
11. To check all levels, set the following conditions, and set the input power level first to avoid an OVER-
LOAD condition.
