GW Instek GDS-2504HD oscilloscope
Details
The GW Instek GDS-2504HD is a 4-channel, 500MHz digital storage oscilloscope designed for reliable everyday measurements in engineering, service and education environments. Its 12-bit vertical resolution shows you more waveform detail, which pays off when you are looking at small signal changes, ripple, noise and power-related measurements. At 500MHz with 12-bit resolution, this is an unusually affordable way into this bandwidth class. The memory matches it: 500Mpts in total, divided over the active channels, so you keep a long capture window at a high sample rate. That helps when you are tracking down an intermittent fault, checking communication behaviour or analysing a switching power supply over a longer time window.
Across the GDS-2000HD/HG series, tools such as serial bus decoding and FFT analysis take care of the common debugging tasks. You operate all of it on a 10.1" capacitive touchscreen running Android, so you can open documents, PDFs and videos directly on the instrument, and screen recording and web control let you share or follow a measurement remotely. The USB and LAN interfaces cover data transfer and remote control from a PC. In addition, the oscilloscope can be powered over USB-C, so it also runs from a suitable power bank when you take it out of the lab.
