RB8510 -- dual 12-bit DAC
Purpose
Generate a unipolar or bipolar voltage.
Description
Module RB8510 is a dual 12-bit Digital to Analog Converter. It contains two 12-bit Digital to Analog Converters (DACs), each connecting to a BNC connector on the front panel. There are no inputs.
Configuration
At production time, each DAC is configured for unipolar or bipolar operation and its output voltage range is defined as 5, 10 or 20V.
The following table shows the volt-per-bit values for the various output voltage ranges.
Voltage range | volt-per-bit bipolar
----------------------+--------------------------
0 .. 5.11875 V | 1.25 mV 0
0 .. 10.2375 V | 2.5 mV 0
0 .. 20.475 V | 5 mV 0
-5.12 .. 5.1175 V | 2.5 mV 1
-10.24 .. 10.235 V | 5 mV 1
For each channel of the DAC module, a separate entry must be made in the Rulbus configuration file.
Default configuration
rb8510_dac12 "name"
{
address = 0xD0,
bipolar = true,
volt_per_bit = 5e-3
}
When the Rulbus configuration file is read, DAC-outputs are set to 0 Volt.
