Test Equipment Description

The Solar 6220-1A Audio Isolation Transformer was especially designed for screen room use in making conducted audio frequency susceptibility tests as required by MIL-STD-461/462 and other EMI specifications.

The transformer may also be used as a pickup device to measure low frequency EMI currents at lower levels than conventional current probes.

In addition, its secondary may be used as an isolating inductor in the power line during transient susceptibility tests. (See Application Note AN622001.)
