HP 85108A Pulsed-RF Network Analyzer System, 2 GHz to 20 GHz

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 85108A Pulsed-RF network analyzer is a factory-integrated system that provides the entire instrument configuration required to make pulsed-RF measurements from 2 to 20 GHz. Specials are available to 50 GHz. Simply add the desired measurement accessories for a complete system. The system is built around the HP 8510C with the pulsed-RF measurement option (Opt 008) already installed. The system also includes the HP 85110A S-parameter test set. An HP 83622B and an HP 83623L synthesized sweeper provide, respectively, the RF and LO signals needed to operate the fundamentally mixed test set.

A factory-integrated system (HP 85108L) is also available for the 45 MHz to 2 GHz frequency range. Custom pulsed bias configurations for high (>100W) and narrow pulses (<1usec) can be integrated into any pulsed-RF system.

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.
