Network/Antenna/Spectrum analyzer Field Strength meter Sweep Frequency Generator

Network/Antenna/Spectrum Analyzer Field Strength meter Sweep Frequency Generator

Description:
- This device is mainly used in debugging various active, passive radio frequency devices live, such as the duplexer, electric-wave filter, amplifier, splitter, mixer, test the standing wave of the aerial and present collinear insertion loss. Increase the appropriate externally positioned attenuation pad, can debug the loops of radio frequency of transmitting set, receiver. In some frequency bands, can also carry on field strength measurement, interference finding out, cabinet fault point location and speed factor measurement.
- The instrument antijamming capability is strong, the dynamic range is big, it is convenient and ocular to debug the duplexer, electric-wave filter, aerial, overhaul in the course in base station, can hand-carry, change at any time. The standing wave test of the aerial adopts the tracking receiver, can finish testing under the strong external disturbing condition, especially suitable for broadcasting the TV transmitting antenna, large-scale shortwave antenna test. 901H has very wide power voltage ranges, can take the direct current power supply between 11.5-32V, it is charged that very convenient and vehicle carried.

   This device can be regarded as specialized communication engineers and technicians, broadcast attenbant instrument always on the alert of TV transmitting station. Used for raising homework efficiency, reduce and take and transport the burden, improve engineering quality.
