OWON SDS215(S) 150MHz 2CH 1GS/s Series Digital Oscilloscope
The OWON SDS215 is a 150 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 (SDS215S) 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.
150 MHz for what most 100 MHz scopes cost
The OWON SDS215 sits in the middle of the SDS200 range and is the one that makes the arithmetic awkward for its competitors: 150 MHz across two independently sampled 1 GS/s channels, for €20 more than the 100 MHz SDS210 and less than most 100 MHz instruments on the market.
The extra bandwidth shows up as a ≤ 2.4 ns rise time, so fast digital edges keep their shape instead of being rounded off. Behind it sits the same 20 million point record length, 7-inch display, 30 automatic measurements, FFT and 6-digit frequency counter as the rest of the series.
Photographed: SDS220S. All three SDS200 models share one chassis, front panel and display — the SDS215 differs only in bandwidth (150 MHz) and rise time (≤ 2.4 ns).
Why the SDS215
More instrument than its size and price suggest: real bandwidth, twenty million points of memory, and an optional signal generator inside the same box.
150 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 ≤ 2.4 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 150 MHz across two independently sampled channels and a 20M record in a 1.1 kg housing, the SDS215 is made for embedded and microcontroller development, switching supplies, digital logic and any bench where 100 MHz is a little tight but 200 MHz is more than the job needs.
- Electronics design, service & repair benches
- Education & training labs
- Makers who want stimulus and measurement in one box (“S”)
- Compact and mobile benches — 301 × 152 × 70 mm, 1.1 kg
- Automated test over SCPI and LabVIEW
- Signals up to 150 MHz, with a ≤ 2.4 ns rise time
- Long captures you zoom into afterwards, using the 20M record
- Filter, amplifier and sensor testing with the built-in AWG (“S”)
- General electronics, audio & power-supply debugging
- FFT spectrum checks and 6-digit frequency measurement
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 150 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 SDS215 that costs €20 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 150 MHz bandwidth, two 1 GS/s channels, 20M record length, 7-inch display and connectivity — only the generator differs.

In the box
The SDS215 ships ready to measure — a probe per channel and every cable you need to get started.
The Q9/BNC lead is standard on the SDS215S and an option on the plain SDS215; 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.
