The Agilent 3070 / 79000 family uses compressed air to
pressurize air cylinders that actuate fixture pull-down
towers. Pull-down towers are used to pull and hold a
fixture down onto the testhead, enabling contact

Connecting Air to the Testhead
Install compressed air lines using rigid line to a point
near the testhead. An air cutoff valve is recommended

when using Performance Port are the maximum that
could be needed. Some installations might require lower
volumes.
