Frequently Asked Questions

Which oscilloscope is better for bench use, the FNIRSI 1013D Plus or the FNIRSI 1014D?

For general bench work, I’d pick the FNIRSI 1013D Plus because the touchscreen makes navigating waveforms so much faster than fiddling with buttons. Both scopes share the same 100MHz bandwidth and 1GSa/s sampling rate, so the core performance is identical. The 1013D Plus also gives you a 6000 mAh battery for 4 hours of use, which is a nice bonus if you want to move your scope around the bench without hunting for an outlet.

Does the FNIRSI 1013D Plus have a signal generator built in?

No, it does not. The FNIRSI 1013D Plus is purely an oscilloscope with a touchscreen and no built-in DDS signal generator. If you need a signal generator integrated into your scope, you’ll want the FNIRSI 1014D instead, which gives you 14 function signals with 1Hz step resolution and can store up to 1000 custom chopping signals.

Is the FNIRSI 1014D worth the extra money over the 1013D Plus?

That depends entirely on whether you need a signal generator. The 1014D costs a bit more than the 1013D Plus at current prices, but you’re getting a 2-in-1 device that saves you from buying a separate function generator. If you already own a signal generator or rarely need one, the 1013D Plus is the better value because you get the touchscreen and longer battery life for less money.

Which FNIRSI scope has a better display for reading waveforms?

The FNIRSI 1013D Plus has the better display experience because it uses a capacitive touchscreen with gesture controls for zooming and panning. Both scopes have a 7-inch screen with 800×480 resolution, so the picture quality is the same. The difference is that on the 1013D Plus, you can directly tap and swipe on the waveform, while on the 1014D you have to use cursor measurement and physical buttons.

Can I use the FNIRSI 1013D Plus and 1014D for high-voltage measurements?

Yes, both scopes come with a 100X high voltage probe, and the 1013D Plus has a built-in high-voltage protection module that can tolerate a continuous voltage of up to 400V. That said, I’d still be careful with anything above 100V and always use the included probe properly. Neither scope is designed for mains-level power electronics without proper isolation.

Which oscilloscope is more portable for moving around a workshop?

The FNIRSI 1013D Plus is more portable by a noticeable margin. It weighs 2.31 pounds and has a 6000 mAh battery that lasts 4 hours, so you can easily carry it around your shop without plugging in. The FNIRSI 1014D is heavier at 3.46 pounds and doesn’t list a dedicated battery capacity, making it better suited for staying put on a bench.
