Simple command structure

The SR245 Computer Interface module is a powerful tool for data acquisition. It provides both an analog and a digital interface between your computer and your experiment.

Analog I/O

The eight analog I/O channels can be designated through software as all inputs, all outputs, or as a combination of inputs and outputs. All channels have 13 bits of resolution over the ±10.24 VDC full-scale range, with 0.05 % accuracy.

Digital I/O

Two front-panel digital I/O bits are provided for use as counters or triggers and can be set or read by the computer. Additionally, an 8-bit input and an 8-bit output port are available (on an internal connector) for your own custom digital interfaces.

RS-232 and GPIB interfaces

Both RS-232 and GPIB interfaces are standard features of the SR245. Simple commands make programming easy from a variety of high level languages all that's necessary is the ability to send and receive ASCII strings. For example, sending "?5" instructs the module to measure the voltage on the 5^th analog input BNC. Other commands allow you to record in the module's 3500 point buffer memory, ramp an analog output at a specified rate (for gate scanning), or read the contents of a digital counter.
