With a 500 kHz analog bandwidth and a real-time sample rate of 10 MSa\/s, it delivers clear waveforms and accurate component testing on the go. The 2.4-inch color TFT display provides crisp visualization, while the built-in rechargeable lithium battery and USB-C charging keep you productive anywhere.\u003c\/p\u003e \u003cp\u003eAs an upgraded successor to the DSO-TC2, the DSO-TC3 enhances capacitance ESR detection, expands the function signal source output, improves bandwidth and sampling rate, and broadens input voltage and diode detection range. These improvements ensure more stable, reliable measurements across a wide range of electronics projects—from quick prototyping to on-site diagnostics. It supports automatic measurement, various trigger modes, and a broad set of tests for diodes, transistors (JFET, IGBT, MOSFET), SCR, TRIAC, capacitors, resistors, and more. It even decodes NEC infrared signals and records temperature and humidity with DHT11 and DS18B20 sensors.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eUse the oscilloscope to quickly visualize waveforms with 500 kHz bandwidth and 10 MSa\/s sampling—great for small circuits and hobby projects.\u003c\/li\u003e \u003cli\u003eTest diodes and transistors, including forward voltage, ESR, and switch characteristics, all in one handheld tool.\u003c\/li\u003e \u003cli\u003eDecode NEC infrared signals and monitor environmental conditions with built-in temperature and humidity sensors for comprehensive circuit testing.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eAnalog bandwidth: 500 kHz\u003c\/li\u003e \u003cli\u003eReal-time sample rate: 10 MSa\/s\u003c\/li\u003e \u003cli\u003eDisplay: 2.4\" TFT color screen\u003c\/li\u003e \u003cli\u003eInput resistance: 1 MΩ\u003c\/li\u003e \u003cli\u003eInput voltage range: 0–40 V\u003c\/li\u003e \u003cli\u003eCoupling: AC \/ DC\u003c\/li\u003e \u003cli\u003eVertical sensitivity (x1): 10 mV – 10 V\u003c\/li\u003e \u003cli\u003eHorizontal time base: 1 µs – 10 s\u003c\/li\u003e \u003cli\u003eTrigger modes: Auto \/ Normal \/ Single\u003c\/li\u003e \u003cli\u003eTrigger types: Rising edge \/ Falling edge\u003c\/li\u003e \u003cli\u003eWaveform Freeze: Yes\u003c\/li\u003e \u003cli\u003eAutomatic measurement: Yes\u003c\/li\u003e \u003cli\u003ePower: Rechargeable lithium battery; Charging via USB-C 5V\u003c\/li\u003e \u003cli\u003eCapacitor range: 25 pF – 100 mF\u003c\/li\u003e \u003cli\u003eResistor range: 0.01 Ω – 50 MΩ\u003c\/li\u003e \u003cli\u003eInductor: 10 µH – 1000 mH\u003c\/li\u003e \u003cli\u003eDiodes: Forward voltage drop \u0026lt; 4.5 V\u003c\/li\u003e \u003cli\u003eMOSFET types: JFET \/ IGBT \/ MOSFET\u003c\/li\u003e \u003cli\u003eSCR: Turn-on voltage \u0026lt; 5 V; gate trigger current \u0026lt; 6 mA\u003c\/li\u003e \u003cli\u003eTRIAC: Turn-on voltage \u0026lt; 5 V; gate trigger current \u0026lt; 6 mA\u003c\/li\u003e \u003cli\u003eDSS\/DS18B20 sensors: DS18B20 0–85°C; DHT11 0–60°C \/ 5–95%\u003c\/li\u003e \u003cli\u003eInfrared remote decoding: NEC protocol\u003c\/li\u003e \u003cli\u003eTest voltage range: 400 V\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eFNIRSI DSO-TC3 handheld 3-in-1 device\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings \/ Reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eDo not exceed the 400 V test voltage range.\u003c\/li\u003e \u003cli\u003eEnsure safe operating conditions; keep the device within 0–40 V input during measurements.\u003c\/li\u003e \u003cli\u003eSelect the appropriate coupling (AC or DC) for accurate signal representation.\u003c\/li\u003e \u003cli\u003eObserve temperature and humidity sensor limits: DHT11 (0–60°C, 5–95%), DS18B20 (0–85°C).\u003c\/li\u003e \u003cli\u003eRecharge only with a proper USB-C 5V charger and undamaged cable.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cp\u003ePlease note: All electronic and mechanical equipment, devices and machines sold to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e","brand":"InterCyprus","offers":[{"title":"DSO-TC3","offer_id":51454663295318,"sku":"1005009212069296-DSO-TC3","price":93.47,"currency_code":"EUR","in_stock":true},{"title":"DSO-TC3 High","offer_id":51454663328086,"sku":"1005009212069296-DSO-TC3 High","price":105.13,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Sea718fedda414509946338159e257adf6.webp?v=1759267183","url":"https:\/\/www.intercyprus.com\/products\/fnirsi-dso-tc3-mini-handheld-digital-oscilloscope-transistor-tester-signal-source-3in1-multifunction-electronic-component-tester","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
