Yes, we have customers worldwide.
Our standard x86 software distributions are compiled for Windows 7/8/10, 32 and 64 bit versions, and for Linux 32 and 64 bit versions. The software is built on top of low level drivers supplied by the operating systems. Distributions for Linux ARM based systems are also supplied for several products. See the Downloads page.
User space source code and examples for custom programming is included. SR drivers and GUI apps like DVM and Scope are proprietary. For review and updates, the latest version of the published software is always available for free from our Downloads page. We encourage prospective customers to review the posted software before purchase to see if it is suitable for their applications.
Yes. The software posted on the Downloads page is the complete distribution. It is the software delivered with the product.
Windows x86 distributions are compiled with Microsoft Visual Studio 2010. Linux x86 distributions are compiled with standard GNU gcc. Linux ARM distributions have been compiled with the gcc for the respective SBC platforms.
All hardware devices require low level device drivers. Operating systems like
Windows and Linux protect system security by preventing users from directly
accessesing the low level instructions required by hardware like disk drives.
All access must go through "protected mode" device drivers.
No. SR products now send their data to output pipelines. Users writing
custom programs in various languages and downstream applications should open
the output pipes from one of our acquisition programs, and then process the
data as required. The beauty is no compiling of the core acquistion programs
or "cross language" interfaces are required, and all processing can be
performed in real time. The pipeline is the interface!
The most complete source of product information is our web site along with the
PDF User Manuals. Both have detailed spec tables covering product performance.
You can download the current PDF User manual and support software for any
product from the
page free of charge.
The circuit diagrams required for interfacing to the boards are included with the PDF User Manual for each product. This includes all connector pin outs and analog front end signal conditioning with op amps and passive elements. Diagrams for the internal digital and power supply sections of the boards are not published. Copies of the PDF User Manuals can be downloaded for free from the Downloads page.
Most of our PDF User Manuals have an "Examples" chapter. This is one of the
best places to find application specific notes for a particular product. The
software distributions have a corresponding Examples directory often with
Our standard wall transformer now has a "universal input", which can accept any
power from 110vac to 220vac. However, the plug is a US "two prong"
plug. International customers will need to find an "adapter" changing
their local wall plug to the US two prong style. The adapter can be a simple
wire connection between the two plug styles without causing trouble.
Yes if the wall transformer is unregulated and can supply the VREF-399 with
14.7v at 60ma.
We use lead based solder, and from that viewpoint are not compliant. However,
we believe all SR products belong to ROHS category 9, and are "compliant by
exemption". Given the typical length of service for SR products exceeds 10
years, we have chosen to avoid the lead free tin whiskers problem and stay with
traditional 63/37 tin lead.
