A test fixture can be used to house a device or test circuit. The test fixture can be a metal or
nonconductive enclosure, and is typically equipped with a lid and an interlock switch. When properly
used, the output of the 2601B-PULSE will turn off when the lid of the test fixture is opened. The test
circuit is mounted inside the test fixture. When hazardous voltages (>30 V
