The SDS1102 is a slim two channel benchtop digital oscilloscope with 100MHz bandwidth, 1GSa/s real-time sampling, a 10K record length and a 7 inch 800 x 480 colour LCD. It runs from 100V to 240V AC and draws under 15W, and its USB device port supports SCPI and LabVIEW remote control from a PC.
Features and Benefits
- 100MHz bandwidth and 1GSa/s sampling on both channels - enough for most repair, audio, power and microcontroller work.
- 5mV/div to 5V/div sensitivity with 8 bit vertical resolution - small ripple and large logic levels on the same instrument.
- 2ns/div to 1000s/div horizontal scale - from fast edges to slow drifts.
- Edge and video triggering (NTSC, PAL, SECAM) with auto, normal and single modes - stable traces and one-off captures.
- Over 20 automatic measurements plus cursors, waveform maths and FFT - rise time, overshoot, duty and phase delay without manual counting.
- Frequency counter and Lissajous X-Y display - check frequency and phase difference between two signals.
- USB host and device ports - save screens and waveforms to a USB stick or control the scope from a computer.
Applications
- Electronics repair and fault finding on switch mode supplies and amplifiers.
- Teaching labs and student benches.
- Embedded and hobby projects that need a second channel for comparison.
- Production checks where a slim bench footprint helps.
In the box
Oscilloscope, 2 probes with accessories (ground springs, colour rings, insulating tips and adjustment tool), USB cable, mains lead, quick guide and software disc, as pictured.
Note: Maximum input is 400V peak to peak (DC+AC). Use the 10X probe setting for higher signals and connect the probe ground only to the circuit ground reference. This page sells the UK plug version.

A: It draws a voltage against time so you can see the shape, size and timing of a signal. The SDS1102 does this on two channels at up to 100MHz, which suits repair, education and embedded work.. Q: What does an oscilloscope measure? A: Voltage over time, and from that the scope works out values such as Vpp, RMS, frequency, period, rise time, duty cycle and the delay between channels A and B.. Q: How do you use an oscilloscope to measure voltage? A: Connect the probe tip to the signal and the ground clip to circuit ground, set the probe to 1X or 10X to match the probe, then press Autoset and read Vpp or RMS from the measure menu.. Q: Can it connect to a computer? A: Yes. Use the included USB cable on the USB device port; the listing states SCPI and LabVIEW support for remote control.. Q: How do you find frequency on this oscilloscope? A: Use the built-in frequency counter or add frequency from the automatic measurement list. Cursors give the time difference between two points for a manual check..
