MSG-2050A GPS Signal Generator

The MSG-2050A is a GPS signal generator designed for generating a simulation signal of GPS (Global Positioning System) satellite, and this unit can be used for adjustment and inspection of car-navigation system with GPS receivers and relative devices.
All operation can be controlled by GP-IB,RS-232C and newly added serial interface,USB for simplifying the operation, and the output level can be switched quickly over a range from -80dBm to -140dBm.
All NAVI data can be preset by GP-IB, RS-232C and also USB, and a Z- count automatic increment function can be preset.
Since this unit is designed to be compact, lightweight, economical and easy-operation signal generators, it is most suitable for using in production lines.

■	Frequency stability of internal reference oscillator is less than 5×10^-8.
■	Rapid changing output level and the level range is from -80dBm to-140dBm.
■	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-232S USB.
■	A Z-count automatic increment function can be preset.
■	This unit is designed to be compact, light weight and economical suitable for production lines.
*	The application program is attached.
