Tektronix unveiled the 2 Series Mixed Signal Oscilloscope (MSO), reimagining what is possible in test and measurement. The new 2 Series MSO can go seamlessly from the bench to the field and back, enabling workflows previously unimagined on a scope. It is the first portable oscilloscope to offer benchtop performance with a familiar Tektronix user interface. Weighing less than 1.8kgs and 38mm thin, the 2 Series MSO can fit into a small backpack, delivering unmatched performance and portability.

Keysight Technologies announced the new Infiniium 8-channel oscilloscope technology. Keysight's Infiniium EXR-Series Mixed Signal Oscilloscopes include eight models ranging from 500 MHz to 2.5 GHz and either 4 or 8 channels with wide-ranging upgradeability. The EXR-Series' waveform update rate is >200,000 waveforms/sec., allowing it to quickly build eye-diagrams capturing 5.7 Million UIs. Powerful and intuitive, the new oscilloscope series reduces test bench and workflow complexity.

When Ethan Winer found himself in need of an oscilloscope, he turned to the Internet for advice and ended up selecting LabNation’s SmartScope. Described by its makers as “the oscilloscope of the new generation” the device, originally funded by a Kickstarter campaign, is targeted at makers and hobbyists, as well as professional engineers. In his review, Winer explains why this digital oscilloscope, signal generator — analog and digital — and eight-channel logic analyzer from LabNation turned out to be perfect solution for his needs.
