National Instruments SC-2040 8 Channel Simultaneously Sampling Differential Amplifier (For MIO-16E Series DAQ Boards) Comes with a manual and what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from National Instruments and may vary slightly due to upgrades, options, or revisions this unit may or may not have. This unit is sold as-is, untested. The Unit's Serial Number Tag Reads: Model Number: SC-2040 Part Number: 182665A-01 Serial Number: AEC46B CE Marked: Yes Description: The SC-2040 is an eight-channel simultaneously sampling differential amplifier for the National Instruments MIO-16E Series DAQ boards. Each channel provides DIP-switch-selectable gain followed by a track-and-hold amplifier. The track-and-hold amplifiers sample all the inputs at the same time, which is useful for preserving interchannel phase relationships. The MIO-16E can trigger the track-and-hold amplifiers, or you can supply an external trigger source. The SC-2040 is a circuit board assembly that is placed on a workbench or mounted in a 19-in. rack. You can configure teh SC-2040 to draw power from the MIO-16E board or from an external +5 V supply. A red LED indicates when the board is powered on. Input signal leads are attached at screw terminals.
