The most important difference between MGS12 and MGS12i is the difference in power supply, as shown in the figure.
What is the differences between MGS12 and MGS12i
Part Number | MGS12 | MGS12i |
Pass DC port | IN, J1 | IN, J1,J2 |
Power Supply Port | J1 Coaxial feed | J1, J2 Coaxial feed |
Block DC ports | J2 with 200 Ω load |
/
|
Product Feature | DC pass-through at J1 to power an active GNSS antenna connected to the input port, a DC isolation at the J2 port, and a 200 Ω DC load to simulate the DC losses of any receivers connected to this port. | Two output ports are simultaneously energized with DC power, and both output ports power the GNSS antenna at the sametime. |
The GS12-DC is powered by its own power adapter to the antenna, so it does not need to rely on whether the receiver has power supply to work normally. This configuration is suitable for some production lines or R & D centers to test products. The input port is usually connected to a GNSS signal source.
