Detailed Description

Purpose

Measure a voltage.

Description

Module RB8509 is a 8-channel 12-bit analog to digital converter (ADC).

The module has eight analog inputs and a trigger input to start a data acquisition. A data acquisition can also be started by a software trigger.

Module RB8509 contains the following parts:

• a channel selector to select one of the eight inputs [ch0..ch7]
• a gain selector to select one of the four gains [1, 2, 4, 8]
• a 12-bit data Analog to Digital Converter

At production time, the ADC is configured for unipolar or bipolar operation and its input voltage range is defined as 10 or 20V.

The following variations of this module are known to exist:

• 8-channel input, no external trigger input
• 4-channel input,

The module's front-panels look as follows.
