Why your next oscilloscope should be a PC-based, USB scope

In today’s fast-paced engineering environments, flexibility, performance, and portability are more important than ever. Traditional benchtop oscilloscopes have long been the industry standard, but they’re no longer the only option. PC-based USB oscilloscopes, like the powerful and compact PicoScope range, are transforming how professionals approach test and measurement.

Whether you're debugging embedded systems, conducting fieldwork, or scaling automated test setups, a USB oscilloscope offers unmatched advantages in speed, size, and software-driven capability. This article explores the key reasons why your next oscilloscope should be PC-based—from portability and deep memory capture to protocol decoding, automation, and seamless collaboration.

Read on if you want to modernise your test bench, reduce downtime, and future-proof your investment.

Common Power Quality Factors Affecting Transformers

Commercial buildings commonly have a 208/120 V transformer in a delta-wye configuration to feed receptacles. Single-phase, non-linear loads connected to the receptacles produce triple harmonics, which add up in the neutral. When this neutral current reaches the transformer, it is reflected into the delta primary winding, which causes overheating and transformer failures.
