HP 85110L Pulsed-RF S-Parameter Test Set

The HP 85110L 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 50W CW. Special options are available 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 85110L 
test set has its internal step attenuators set to 0 dB.  The 
test can handle up to 50W (+47 dBm) or power if the step attenuators
are activated and proper precautions are taken within the open 
architecture loops.
