To meet the need of Beijing Synchrotron Radiation Facility (BSRF) in two-dimensional detectors, a two-dimensional position sensitive X-ray gas electron multiplier(GEM)detector based on PCB strips and anolog readout were designed and constructed. Through the test of two kinds of strip pitchs and based on the system of multi-channel charge sensitive preamplifier and VME buffer-ADC, the spatial resolution of soft X-ray was measured and pretty good spatial resolutions of about 84 μm and 75μm respectively were obtained. The effect of the sum of the voltages applied on the three GEM foils on the spatial resolution was studied and position veracity and linearity of GEM was tested. The principles of GEM based on anode readout and the anolog electronic system were clarified meanwhile.
