Abstract

The invention relates to a capacitive touch sensor tester which comprises a DSP, a source program memorizer, a correcting interface, a static random memorizer, a first CPLD and a second CPLD. Signal output and feedback are achieved, the first CPLD is connected with a scanning card control interface, a power-down automatic memorizer and a communication circuit to achieve signal output and feedback, and the second CPLD is respectively connected with a DDS, a programmable amplifying circuit, a programmable I / V conversion circuit, an output selection switch and a digital-to-analog conversion D / A to achieve signal transmission. The DSP sends out measuring signals, signals obtained by measuring a tested object by a scanning card are transmitted to a programmable amplifier to be converted into voltage signals suitable for being measured, a main LFP low-pass circuit converts analog signals into digital signals through an ADC, impedance, inductance values, capacitance and the like with the high activity accuracy are processed through the DSP, testing is efficient and fast, and observation, metering and later analysis are facilitated.
