Description
Technical field
The utility model relates to a kind of signal generator, especially a kind of hand-hold type signal generator.
Background technology
When carrying out Data-Link directional antenna tracking test, need the special waveform signal generating means of convenient movement.Current hand-hold type signal generator both domestic and external only supports that fixed waveform occurs, and does not still possess special waveform generating ability.Normally be installed in kart by airborne equipment in test and realize, which needs man power and material's cost of at substantial, and also has higher requirements to test site.
Summary of the invention
In order to overcome existing airborne signal generation apparatus system complex, mobility poor, high problem is required to test site, the utility model provides a kind of handheld specialized waveform generator, effectively can improve equipment flexibility, reduce test difficulty and cost.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of hand-hold type signal generator, comprise hand-hold type housing 11, be provided with printed circuit board (PCB) 6 in described hand-hold type housing 11, described printed circuit board (PCB) 6 is integrated with baseband module and radio-frequency module, and described baseband module is made up of programmable chip.
Further, described printed circuit board (PCB) 6 is also integrated with power management module, is also provided with rechargeable battery 1 in described hand-hold type housing 11, and described rechargeable battery 1 is charged for printed circuit board (PCB) 6 by rechargeable battery cable 4.
Further, described printed circuit board (PCB) 6 is also integrated with display control module, and described hand-hold type housing 11 surface is provided with liquid crystal display screen 2, and described liquid crystal display screen 2 carries out transfer of data by liquid crystal display screen cable 3 and printed circuit board (PCB) 6.
Further, described hand-hold type housing 11 surface is provided with keyboard 7, and described keyboard 7 is connected to printed circuit board (PCB) 6 by keyboard cable 5.
Compared with prior art, the beneficial effects of the utility model are: baseband module can complete various special waveform generation by rewriting program, and hand-hold type signal generator only needs people's manipulation, easy to use, flexible.The utility model hand-hold type signal generator heavily about 550g, output frequency covers 6.0 ~ 6.6GHz, and output power signal can reach 0dBm, and in 2 hours cruising time, man-machine interface is excellent, simple to operate.Very large help can be provided for antenna tracking test, respond well, be worthy to be popularized.
