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.
