A new year for high frequency!

We enter 2023 with the goal of defeating the chip shortage and expanding our 30 and 40GHz lineup! We are already seeing lead times falling and less out-of-stock components. As always we will continue to polish our software, firmware, and hardware designs, and bring our clients the best possible test equipment user experience!

We at DS Instruments want to wish everyone a happy and successful new year. We will be trying our best to continue to offer as many of our products as possible through the continuing 2022 chip shortage!
