The recent upgrade of the Hall probe measurement system at the Magnetic Measurement Facility is reported. The upgrade includes replacement of obsolete hardware and step motors by modern components and servomotors integrated with an encoder, servoamplifier and intelligent controller. Control software for the upgraded system was developed with Visual Basic and integrated with a program for analysis of magnetic data for insertion devices. The upgrade resulted in higher accuracy of the magnetic measurements due to significant reduction of electrical noise.
