MSG-2051A GPS Signal Generator

The MSG-2051A is a high performance GPS signal generator designed for generating a simulation signal of GPS (Global Positioning System) satellite, and used in combination with a simulator base station for mobile phones, this unit is widely used in R/D, inspection, production, maintenance department of mobile phones terminals.
This unit adopts a reference clock (10MHz) input/output terminal and also 1pps signal input/output (output on option) terminal so as to synchronize a mobile phones with a simulator base station.
All operation can be controlled by GP-IB ,RS-232 and newly added serial interface, USB for simplifying the operation, and the output level can be switched quickly over a range from -80dBm to -149.9dBm.
All NAVI data can be preset by GP-IB,RS-232C and also USB, and a Z-count automatic increment function can be preset.

■	Frequency stability of internal reference oscillator is less than 2×10^-8.
■	Rapid changing output level and the level range is from -80dBm to -149.9dBm (-60dBm to -129.9dBm).
■	Doppler frequency (1.57542GHz ±10kHz) can be set digitally.
■	The output terminal is DC-cut to able to connect to the powered antenna cable.
■	All NAVI data preset by GP-IB and also RS-232C and USB.
■	A Z-count automatic increment function can be preset.
*	The application program is attached.
