HP 85110A Pulsed RF S-Parameter Test Set, 2 GHz to 20 GHz

The HP 85110A test set is specially configured for operation in pulsed-RF measurement systems. Four 90 dB step attenuators protect each input of the fundamentally-mixed down converter to allow measurement of test devices with output power of 20 W CW. Special test set options are available from .5 to 20 GHz and 2 to 50 GHz.

¹Limited by compression level and system noise floor.  
Noise floor is measured with full two-port error correction, 
1024 averages.
²This maximum power measurement assumes that the 
HP 85110A test set has its internal step attenuators set to 0 dB. 
The test can handle up to 20 W (+43 dBm) or power if the step 
attenuators are activated and an isolator is installed (in the port 
2 real panel link).
