High-Speed Digitizers, AWGs & Digital I/O
East Coast Representative

Spectrum Instrumentation, founded in Germany in 1989, designs and manufactures the most comprehensive line of modular PC-based signal acquisition and generation products available. Their products are used wherever engineers and scientists need to capture or generate electronic signals at rates, resolutions, and continuous throughput levels that standard bench instruments cannot achieve.
The defining characteristic of the Spectrum product line is its modular architecture: over 250 different digitizer and AWG configurations sharing a single driver interface across PCIe, PXIe, and LXI/Ethernet platforms. One software framework, one API, any platform.
ARS Technical Sales Corp serves as the East Coast representative for the full Spectrum Instrumentation product line. All technical inquiries are handled directly by Phil Gregor, who spent the decade prior to founding ARS working with Acqiris and Agilent Technologies data converter products — the direct predecessor category to Spectrum’s current line.

Five years on every product — not a promotional tier, not a registration requirement. Spectrum’s standard warranty is the longest in the digitizer category. For program-critical instrumentation that needs to be supported for the life of a development effort, that commitment is worth evaluating on its own.
Spectrum’s technical support comes directly from the engineering team in Grosshansdorf, Germany — the same engineers who designed the hardware and wrote the firmware. No tiered support system, no call center, no escalation queue. When a question requires a real answer, it comes from the source.
PCIe, PXIe, or LXI/Ethernet — the same SBench 6 software, the same driver API, the same programming model across all 250+ product configurations. Changing platforms or scaling channel count does not require rewriting software. That is not the case with most competing product lines.
Phil spent a decade at Acqiris USA and Agilent Technologies working with the high-speed digitizer product line that directly preceded Spectrum’s current offerings. He is not learning the application space alongside you — he built OEM accounts in radar, lidar, mass spectrometry, and medical imaging using directly comparable hardware before Spectrum’s US presence existed.
