GPIB Logic Levels

The attenuator GPIB lines use standard TTL logic, as follows:

•True = Low = digital ground or 0Vdc to 0.4Vdc

•False = High = open or 2.5Vdc to 5Vdc

All GPIB lines have LOW assertion states. High states are held at 3.0Vdc by pull-ups within the instrument. When a line functions as an input, it requires approximately 3.2mA to pull it low through a closure to digital ground. When a line functions as an output, it can sink up to 48mA in the low state and approximately 0.6mA in the high state.

The GPIB line screens are not isolated from ground.

A.9 Claims and Repackaging

If physical damage is evident or if the instrument does not meet specification when received, notify the carrier and the nearest Agilent Technologies Service Office. The Sales/Service Office will arrange for repair or replacement of the unit without waiting for settlement of the claim against the carrier.

Return Shipments to Agilent Technologies

If the instrument is to be shipped to an Agilent Technologies/ Service Office, attach a tag showing owner, return address, model number and full serial number and the type of service required.

The original shipping carton and packing material may be reusable, but the Agilent Technologies/Service Office will provide information and recommendation on materials to be used if the original packing is no longer available or reusable. General instructions for repacking are as follows:
