In this paper, we introduce a novel time domain correlation based channel sounder that operates at 485 GHz. The channel sounder targets the Y-band ($330 \text{GHz}-500 \text{GHz}$) and covers a center frequency up to 500 GHz. The setup has been validated in the laboratory for conducted and over-the-air measurements. The conducted measurements report a dynamic range of around 80 dB without spurious peaks, and a linear behavior between added attenuation and dynamic range with constant relative noise floor. The over-the-air measurements report a match of the line-of-sight path's propagation length and normalized received power.
