Something else that I should've mentioned: You should NEVER connect any of the newer generators to any radio directly. You need at LEAST a capacitor between the generator output and the device under test. I have HP11509A fuses which connect to the output of the generators so that IF anything get reverse applied to the output, the fuse blows. These things take a 60 milliamp fuse and it's inside of a barrel that's tested flat to 1 Ghz. That's not necessary for what we do here. You could do the same thing in a shielded box with two BNC connectors and the fuse in a fuseholder inside. You get the same protection, it's just not flat impedance wise. Again, no big deal here.
The other thing to keep in mind is that an isolation transformer is a must for AA5 radios. You'll kill a generator REAL QUICK if you don't have one. Don't ask how I know .
