TEKTRONIX A6902A Isolator

The A6902A Isolator is a dual-channel, optical-coupled and transformer-coupled voltage isolator that allows safely grounded test instruments to make floating measurements at high sensitivity levels in the presence of large common-mode signals. The unit acts as a buffer between the test instrument and the system under test and extends the range of the test instrument to 1500 V (dc plus peak ac) with the larger industrial probe and 500 V (dc plus peak ac) with the smaller signal probe. Both probes are quickly interchangeable at the cable connectors. The two pairs of probes and output cables are stored in removable side pouches for availability and convenience. Designed for use with any dual-channel scope.
