OWON SDS220(S) 200MHz 2CH 1GS/s Series Digital Oscilloscope
The OWON SDS220 is a 200 MHz, 1 GS/s digital storage oscilloscope with 2 channels, ideal for education, labs, and electronics troubleshooting. Compact and lightweight, it offers a 7″ TFT color display, 20M record length, and advanced math/FFT functions for in-depth signal analysis.
The S model (SDS220S) includes a built-in waveform generator, providing standard sine, square, ramp, and pulse outputs up to 25 MHz, plus 16 arbitrary waveforms — making them versatile all-in-one tools for testing, design, and repair.
200 MHz, and the generator for €10 more
The OWON SDS220 tops the SDS200 range: 200 MHz across two independently sampled 1 GS/s channels, with a ≤ 1.75 ns rise time — fast enough to show the real shape of an edge rather than a smoothed impression of it.
It keeps everything that makes the series worth having: a 20 million point record length for long captures you can zoom into afterwards, a 7-inch colour display, 30 automatic measurements, FFT and a 6-digit frequency counter. On this model the “S” version, with its built-in 25 MHz arbitrary waveform generator, costs only €10 more — the cheapest second instrument you will buy this year.
Why the SDS220
More instrument than its size and price suggest: real bandwidth, twenty million points of memory, and an optional signal generator inside the same box.
200 MHz on two 1 GS/s channels
Each channel has its own sampler, so the full 1 GS/s stays available with both channels running — no halving when you turn the second one on. Rise time ≤ 1.75 ns, vertical sensitivity 2 mV to 10 V/div.

Built-in 25 MHz generator (S)
The “S” version adds a 14-bit, 125 MSa/s waveform generator: sine to 25 MHz, square and pulse to 5 MHz, ramp to 1 MHz, plus 160+ arbitrary waveforms — stimulus and measurement from one instrument.

20M record length, 30 measurements
A 20 million point record captures seconds of signal in one sweep; scroll and zoom into it afterwards without re-triggering. 30 automatic measurements, FFT, waveform math and a 6-digit hardware frequency counter do the analysis.
Record length is how many samples the instrument stores per acquisition. Together with the sample rate it sets how long a window you can capture without dropping resolution.
Sample rate and time window trade against each other for a fixed memory. Deep memory is what lets you hold a long sequence at full rate instead of choosing between seeing the whole frame and seeing the edges inside it.
In practice: Capturing a full 20 ms mains cycle while still resolving a 100 ns switching spike inside it needs deep memory; a shallow buffer forces you to pick one or the other.
SCPI & LabVIEW control
A USB Host port on the front takes a memory stick; the USB Device port on the back drives the scope from a PC. SCPI commands (including an :AG subsystem for the generator) plus LabVIEW support, free OWON software and programming demos turn it into the core of an automated setup.
Who it’s for & best applications
With 200 MHz across two independently sampled channels and a 20M record in a 1.1 kg housing, the SDS220 is made for fast digital and embedded work, power-electronics switching edges, RF-adjacent bench work and anyone who would rather not discover a bandwidth limit halfway through a project.

Choose your version
Click a version below and it is selected in the picker at the top of this page — the price and the Add to cart button follow immediately. The “S” version is the same 200 MHz oscilloscope with a 25 MHz arbitrary waveform generator built in: a 14-bit, 125 MSa/s source with sine, square, ramp, pulse and 160+ arbitrary waveforms on its own front-panel BNC. On the SDS220 that costs €10 more — and it comes with the Q9/BNC lead as standard.
Prices shown incl. VAT, exactly as listed in the variant picker above. Both versions share the same 200 MHz bandwidth, two 1 GS/s channels, 20M record length, 7-inch display and connectivity — only the generator differs.

In the box
The SDS220 ships ready to measure — a probe per channel and every cable you need to get started.
The Q9/BNC lead is standard on the SDS220S and an option on the plain SDS220; a padded soft carrying bag is available as an option on both. There is no CD — the PC software is a free download, see the Downloads section below. Box contents subject to final delivery.
Other models in the series
Slower signals and a tighter budget? The SDS215 (150 MHz) and SDS210 (100 MHz) are the same instrument with less bandwidth. Every SDS200 shares the same two independently sampled 1 GS/s channels, 20M record length, 7-inch display, 30 automatic measurements, FFT and 6-digit counter — and every one is available with or without the 25 MHz generator.
