3.2 Rack Mounting
To facilitate mounting the instrument in a standard 483 mm (19 inch) equipment rack, the 1073A
includes a pair of rack-mounting ears. To install the rack mounting ears:
1. Using a T-25 driver, remove the two screws on one side of the unit. Leave the cover in place.
2. Position one of the rack mounting ears on the side of the unit, so that the rack mounting
flange is at the front of the instrument and extends away from the front panel.
3. Replace the cover screws by routing them through the lower set of holes in the rack-mounting
ear, and back into the threaded holes in the instrument.
4. Repeat the above steps for the opposite rack-mounting ear.
