VZM-2780P2

M-Band
CPI 900W M-Band TWT System
Compact
Provides 900 watts of power in the 8.0 to 18.0 GHz frequency
band in a compact 19-inch rack-mount multiple drawer
configuration suitable for wideband testing.
Efficient and Reliable
Employs CPI dual-depressed collector helix traveling
wave tubes, increasing efficiency by a nominal 20% over
conventional single collector TWTs, and a power supply
designed with a minimum number of parts for
maximum uptime.
Simple to Operate
Integrated microprocessor control lets the user adjust and
monitor all operating parameters from one easy-to-read local
or remote panel, using straightforward menu-driven commands. Includes a built-in interface and serial bus for
operation from the station computer.
Safety
Conforms to international safety and EMC
compliance standards.
Easy to Maintain
Modular design provides for easy installation and
maintainability in the field.
Worldwide Support
Backed by over 35 years of satellite communications
experience, and CPI’s worldwide 24-hour customer support
network that includes more than 20 regional factory
service centers.
