MEGURO MSG-2050 GPS信号发生器|日本目黑|GPS信号源

品牌：日本目黑 MEGURO

MSG-2050 is a signal generator designed for generating the simulation signal of GPS (Global Positioning System) satellite.

特点

■Frequency stability of internal reference oscillator is less then 5×10-7

■Rapid changing output level and the level range is from -80dBm to -140dBm

■Doppler shift function is not built-in

■The output terminal is DC-cut to able to connect to the powered antenna cable.

■All NAVI data preset by GP-IB line and also RS-232C.

■An automatic Z count increment function is equipped so as to synchronize with real time clock.

■The front panel operation can be programmed by GP-IB and RS-232C.

* The application program is attached.
