Adaptable to most Signal Amplification Applications

The USBPIA-S1 stand alone USB controllable module provides a single channel high-quality instrumentation amplifier for front-end signal conditioning. It is compatible with all popular A/D converter devices. The custom software control makes the USBPIA-S1 very suitable for automatic gain compensation applications. The USBPIA-S1 is powered by 9 to 12VDC so it can be directly connected to a regulated DC voltage source. For use with unregulated DC power use the optional USBPxx-S1/DCR DC voltage regulator for battery or solar DC power sources from 9 to 30VDC. Alternatively, the included 115-220VAC adapter can be utilized to accomodate wall power anywhere in the world. When programmed from the USB port, the USBPIA-S1 will remember all of the programmed properties between power cycles. Program once and operate as a stand-alone signal conditioner without having to reprogram for every use. This is perfect for turn-key applications. It's easy to connect the USBPIA-S1 into the data collection system. Input and output signals can be routed through BNC connection or by using the detachable screw terminal connectors.


Multi-channel Convenience

USBPIA-S1 software controlled variable gain instrumentation amplifier in a multi channel USBDR-8 mounting platform

For multi-channel convenience populate the USBDR-8 USB and power distribution rack with USBPIA-S1 modules. The USBDR-8 can hold up to 8 modules and can be daisy chained to create very large channel counts with one host computer. Click here to find out more about the USBDR-8.


Connection to the Data Acquisition System

All I/O connections from the USBPIA-S1 are made via two BNC connectors or from the supplied removable screw terminal connectors.


How to Order

The USBPIA-S1 comes complete with everything you need to connect, power, program and quickly integrate it into the data collection system. Please fill out the Request Prices form and we will eMail our price list and complete information about included accessories and the best way to submit a purchase request. Below is a table of part numbers and configuration options. The required filter characteristic must be specified when ordering.

Support Software

Alligator Technologies has developed SystemViewUSBPxx, a Windows based dialog interface to the USBPIA-S1 unit. Just plug any number of USBPIA-S1 units into the USB of the host computer and each unit will be individually recognized. The operating parameters can be changed for each unit or for all attached units with just a couple clicks of the mouse. Set the corner frequency at any value, select the amplifier gain, or even give the USBPIA-S1 a unique name.



Menu-Driven Software

The USBPIA-S1 is supplied with SystemViewUSBPxx for Windows for control of the gain and AC or DC coupling functions.  Pictured is the software control dialog for controlling one or all USBPIA-S1 units connected to the host computer.  The control of the USBPIA-S1 is straight forward and intuitive.  To obtain the gain or coupling use the pull down lists.  Simply click the Program button to send the parameters through the USB to the USBPIA-S1.  In systems where more than one USBPIA-S1 is connected each unit will be represented by an individual channel dialog window cascade from the upper left of the screen. The contents of the dialog will reflect the current configuration of each unit.

SDK for Custom Software Applications

The SystemViewUSBPxx is built on top of a COM(ActiveX) object that can be dropped into any custom application. The COM can be interfaced with LabView, MatLab, C++, VisualBASIC, C# or any other high level language to directly control USBPxx devices. We provide example application software written in C++ that describes this interface in great detail. The SDK is included with the purchase of any USBPxx product.
