Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE11102:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description **For extra-low-voltage circuits only (under 50 V AC or 120 V DC). Not for mains-voltage measurements.** See signals up to 1 MHz on a palm-sized, battery-powered scope that also works as a 10 kHz function generator. It captures at 5 MS/s with Auto, Normal and Single triggering, so it handles repeating analogue waveforms and one-off digital events. You don't need a bench scope to check a PWM output, watch a sensor respond or show what a square wave really looks like. Long-press AUTO and the scope sets the scale and timebase for you and puts the waveform on screen. That makes it a friendly first oscilloscope for students and hobbyists, and a handy spot-checker for low-frequency work. The built-in DDS generator outputs 14 waveforms from 0.1 to 3.3 V, so you can drive a filter, amplifier or input stage and look at the result on the same device. Everything runs from a 1000 mAh rechargeable battery (about 4 hours per charge) with USB-C charging, in a 99 x 68.3 x 19.5 mm body that fits in a toolbox or pocket. Need more bandwidth? The [DSO-510](https://core-electronics.com.au/fnirsi-dso-510-oscilloscope.html) uses the same compact form factor with a 10 MHz / 48 MS/s front end and a 50 kHz generator. ### Features - **Get a readable waveform in seconds** with one-press AUTO, which configures the scale and timebase without manual tuning - **Catch one-off events as well as repeating signals** with Auto, Normal and Single trigger modes on rising or falling edges - **Stimulate and measure with one tool** via the built-in 10 kHz DDS generator, which offers 14 waveforms including sine, square, sawtooth, step and noise - **Measure higher signal amplitudes** using an X10 probe (sold separately), which extends the input range from ±40 V to ±400 V within extra-low-voltage limits - **Work anywhere, no power point needed**, thanks to a 1000 mAh lithium battery with about 4 hours of runtime and USB-C charging - **Read traces clearly** on a 2.8-inch 320 x 240 colour display, with AC/DC coupling ### Specifications | **Property** | **Specification** | |---|---| | Channels | 1 | | Bandwidth | 1 MHz | | Sampling Rate | 5 MS/s (real-time) | | Vertical Sensitivity | 10 mV/Div – 10 V/Div (1-2-5 steps) | | Time Base Range | 500 ns/Div – 20 s/Div (1-2-5 steps) | | Input Voltage Range | ±40 V (80 Vpp) with X1 probe \| ±400 V (800 Vpp) with X10 probe | | Trigger Modes | Auto / Normal / Single | | Trigger Edge | Rising / Falling | | Coupling | AC / DC | | Signal Generator Frequency | 0 – 10 kHz | | Signal Generator Amplitude | 0.1 – 3.3 V | | Duty Cycle | 0 – 100% (rectangular and sawtooth waves) | | Waveforms | 14: sine, rectangular, sawtooth, half-wave, full wave, step, anti-step, noise, exponential rise, exponential fall, DC, multi-tone, sinc pulse, Lorentz | | Display | 2.8-inch TFT LCD, 320 x 240 | | Battery | Built-in 1000 mAh lithium (approx. 4 hours runtime) | | Charging | USB Type-C, 5 V / 1 A | | Languages | English, Chinese, Russian, Japanese, Spanish, Portuguese, German, Korean | | Operating Environment | -5 to 40 °C, ≤80% RH | | Dimensions | 99 x 68.3 x 19.5 mm | | Weight | 100 g | ### What's Included - 1x DSO-153 oscilloscope - 1x alligator clip probe - 1x charging cable - 1x lanyard - 1x user manual ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/C/E/CE11102_ecommerce_1790657293067.jpg)
