Description

High quality low noise passive resistance 1000:1 and 100:1 attenuators

designed for general laboratory work.

The 9766 and 9767 have been designed to complement the 5018, 5025

and 5051 laboratory calibrators by allowing small AC or DC signals with

low noise to be processed from the 2 and 20 volt ranges.

The 9766 attenuator (1000:1 version) allows 10 kΩ input resistance. The

9767 (100:1 version) allows 1 kΩ input. Output resistance is 10 Ω for both.

Connection is made via BNC leads using 4 mm to BNC adaptors. These

are available as individual extras or come as standard with the 9796

premium test lead set for multifunction calibrators.

Both units are housed in a heavy duty die cast case for robustness, with

an air tight seal between the lid and the case body.
