Inspection and Maintenance

Initial Inspection

When you receive your U2761A, inspect the unit for any obvious damage such as broken terminals or cracks, dents, and scratches on the casing that may occur during shipment. If any damage is found, notify the nearest Agilent Sales Office immediately. The front of this manual contains the warranty information.

Keep the original packaging in case the U2761A has to be returned to Agilent in the future. If you return the U2761A for service, attach a tag identifying the owner and model number. Also include a brief description of the problem.

Electrical Check

The U2761A USB Modular Function/Arbitrary Waveform Generator Service Guide will provide the complete verification and calibration procedures. The procedures will verify to a high level of confidence that the U2761A is operating in accordance with its specifications.

General Maintenance

	N O T E	Any repair that is not covered in your modular product manuals should
	N O T E	only be performed by qualified personnel.
		only be performed by qualified personnel.

		1	Power off your module and remove the power cord and
			I/O cable from your device.
		2	Remove your module from the bumper casing.
		3	Shake off any dirt that may have accumulated on the
			module.
		4	Wipe your module with a dry cloth and install the
			bumper back in place.
