The 3600D Cellular Test System offers simplicity of operation with a one touch automated test button, allowing unskilled personnel to run a complete Go/No Go test of a cellular phone. Tests are displayed on a large easy to read LCD display with soft key driven screens that provide a complete summary analysis of analog or digital performance to improve repair and testing times. The display has technician selectable inverse video capability. The 3600D allows for reprogramming channel parameters, base and mobile transmit power levels. Test Set features can be directly loaded into the 3600D via its PC compatible disk drive. Increased flexibility is provided with a cross point switch that controls the input and output of internal generators and filter combinations.
