This unit

The Keysight/Agilent/HP 9100-4715 is a replacement power transformer engineered for the 3458A Digital Multimeter. This E-core transformer delivers essential voltage conversion and isolation required to maintain the precision measurement integrity of the 3458A platform. Dual shielding and an integrated guarding cage minimize mains noise coupling, establishing clean, isolated power domains that protect sensitive analog circuitry from electromagnetic interference. The transformer mounts on a sturdy metal chassis frame positioned behind the front panel and VFD display, away from analog signal paths. This strategic placement ensures optimal isolation from high-frequency switching noise and field disturbances that could degrade multimeter accuracy.
