APPLICOS DRS20 Module
A dual-channel reference source offering ultra high precision and stability
The DRS20 provides a +/-10 V output. The output current can be up to 10 mA and the 4 wire connection provides a 1 µV/mA load regulation. The high precision and stability is achieved by using a temperature controlled voltage reference. All internal nodes are calibrated using a built in 24-bit precision DVM that continuously checks the internal nodes relative to this reference. Therefore the accuracy is only determined by the temperature controlled voltage reference. This ensures a negligible drift when sourcing over a long period of time. The same DVM can be used to measure external voltages with extremely high precision.
The output has a very low noise level. Special attention has been paid to low frequent noise (<10 Hz) since this is very difficult to filter away afterwards. The unit is very suitable as the reference source for data converter testing.
