OV-33

Magnetic - screened type-O backward-wave tubes with magnetic focusing are used in microwave measuring systems.
Low steepness of electronic tuning, low spectral density of amplitude fluctuations' power, wide frequency band provide the usage of the type-O backward-wave tubes in measuring equipment as optimal devices.
Input and output - coaxial.
Cooling - without special cooling.
