Installation Instructions
Checking Trigger
Create a trigger mask and check that the trigger functions properly.
Equipment needed:
You will need the following equipment to perform this procedure:
H One signal generator
Minimum requirements: Frequency of 1.5 GHz and amplitude of –10 dBm.
H One 50 W N-N cable
1. Prepare for the test:
a. Set the signal generator controls:
Frequency 1.5 GHz. . . . . . . . . . . . . . . . .
Amplitude –10 dBm. . . . . . . . . . . . . . . .
RF output Off. . . . . . . . . . . . . . . . .
NOTE. Turn the RF output off initially.
b. Hook up the generator: Connect the generator output through a 50 W
N-N coaxial cable to the analyzer INPUT. See Figure 9.
