A Hall probe insertion device (ID) measurement system has been developed to characterize the IDs at the Advanced Photon Source (APS). The system uses the latest state-of-the-art field programmable gate array (FPGA) technology to synchronize the position and Hall voltage measurements. Data block first-in-first-out (FIFO) has been implemented to transfer the data from the FPGA to the host computer during measurement. The system is capable of continuous scanning measurements on a full 6 meter bench at 1 ms per data point with the position resolution of 1 micron and Hall voltage precision of 5-1/2 digits.
