Where to Buy an Oscilloscope

TRIO has been the go to place for many looking at where to buy an oscilloscope. We are the distributor for Keysight Technologies, previously known as Agilent and Hewlett Packard before that. Keysight have a full spectrum of oscilloscopes ranging from hobbyist models through to high-end, high-performance mega scopes!

In Keysight’s own words:

Oscilloscopes from extreme value to extreme performance.

Whether you need the fastest real-time oscilloscope on earth with the highest measurement accuracy anywhere, the only capacitive touch screen oscilloscopes, or something a little more basic, Keysight oscilloscopes outperform in every category. We are working continually to bring you oscilloscopes with breakthrough capabilities that help you solve your toughest measurement challenges. Like you, we’re working on what’s next.

High Speed Bench Multimeter from Siglent

The SIGLENT SDM3055 Bench Multimeter has a powerful measurement test engine, measuring speed up to 150rdgs / s, 1Gb Nand total memory capacity, mass storage instrument settings, historical data, and external U disk external storage. The SDM3055 interfaces include USB Device, USB Host, LAN and GPIB (SDM3055A). It can support VXI11, USBTMC remote control as well as interconnection with National Instruments’ LabVIEW. A SCPI command programming manual is also provided in support of remote control operation programming.It is compatible with mainstream multimeter command sets and uses the compatible language with SCPI for transmission and control. Thus you can convert from your existing test environment easily.
