MSXB 082 4-channel signal interface module

A simultaneous sampling product protects your application from ground loops and lets you sample at very high speeds. It is a 4-channel signal interface (SI) module, part number MSXB 082, with four onboard analog-to-digital converters and channel-to-channel isolation. The four analog-to-digital converters on the SI module are synchronized to within a few nanoseconds of each other, and each one can convert an analog signal to a 16-bit data stream at up to 1.25M samples/second. All inputs are differential, and each analog channel is isolated from all the others and from any other system component. You can set the gain of each channel to 1, 2, 5, or 10 in software, and channels can have different gains. The MSXB 082 design allows each of four channels to sample at 1.25M samples per second. Initially the per-channel maximum is reached if only one channel is in use. With two channels in use, the maximum is 1M samples per second; with three, 667k samples per second; and with four, 500k samples per second. Planned upgrades to other system components will allow the new product to sample at full speed—1.25M samples per second per channel—on all channels simultaneously. No changes are required to the product itself.
