HP 85108L Pulsed-RF Network Analyzer System, 45 MHz to 2 GHz

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 85108L Pulsed-RF network analyzer is a factory-integrated system that provides the entire instrument configuration required to make pulsed-RF measurements from 45 MHz to 2.3 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) and includes two HP 83620B Option H80 synthesizers. The system is optimized for component testing in applications such as cellular, direct broadcast satellite, and VHF/UHF. The HP 85108L has excellent pulsed-RF and CW performance with system dynamic range greater than70 dB when using the sideband detectors and better than 95 dB when using the standard narrowband detectors. 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 panellink.
