The solution, TekHSI (Tektronix’s high speed interface), functions as a new firmware capability on the Tektronix MSO 4B, 5 and 6 Series models (including B and LP instrument renditions). The abstractions provided in TekHSI make it possible to achieve higher data transfer speeds with easy-to-use implementation and scaling abilities, and TekHSI enables users to capture the highest performance output from an instrument’s physical link, such as ethernet, and transfer data at higher speeds.
Current test and measurement solutions tend to require meticulous code optimisation to achieve high data transfer rates, relying on standard commands for programmable instruments (SCPI) such as curve and curvestream to move data from instrument to computer. This makes it difficult for test and measurement engineers to maximise the bandwidth of the physical link their instruments are shipped with, typically 1 Gbps ethernet.
TekHSI provides an alternative to achieve higher data transfer speeds, with the abstractions provided in TekHSI making it easy to implement, use, and scale.
“Before the launch of TekHSI, our customers had to depend on SCPI curve and curvestream commands for data transfer, and those methods resulted in workflow bottlenecks for test and measurement engineers working with large record length and sample rate waveform files,” explained Gaurav Marmat, Tektronix Product Manager. “TekHSI is based on Google’s modern remote procedure call architecture and is very intuitive to adopt and scale across test automation needs for faster, more efficient data transfer results. It’s an alternative to those complex and slow data transfer options.”
Tektronix TekHSI is available now through a Python library for automation projects, with the TekScope PC version 2.10 also available for user interface-based applications.
