-The ALM1000 contains two 16 bit 100KSPS analog to digital converters and two 16 bit digital to analog converters. Along with a means to source both voltage and current with the DACs the system can simultaneously measure the current or voltage. These inputs and outputs are often used to measure time varying waveforms as in the [[university:tools:alice-1.0-users-guide|ALICE oscilloscope interface]]. However, there are often times when simple, accurate, DC measurements are required such as in a resistor network. The following Python interface is provided for that purpose. It provides the means to more accurately calibrate the measurements than provided by the factory calibration contained on the ALM1000 board itself.+The ALM1000 contains two 16 bit 100KSPS analog to digital converters and two 16 bit digital to analog converters.

-To demonstrate using the ALM1000 to measure current while sourcing voltage consider the resistor current divider circuit shown in figure E1. We would like to measure the currents flowing in resistors R<sub>S</sub> and R<sub>2</sub> while supplying 5V to R<sub>S</sub>. We will be using R<sub>S</sub> = R<sub>1</sub> = R<sub>2</sub> = 100? for this example.+To demonstrate using the ALM1000 to measure current while sourcing voltage consider the resistor current divider circuit shown in figure E1.
