Description
The Dual Channel Analog Oscilloscope, 20 MHz with Probes, also known as a dual-channel laboratory oscilloscope or educational CRO, is designed for observing and comparing electrical waveforms in laboratory and teaching environments. This unit is listed as a double channel analogue oscilloscope with 20 MHz bandwidth, suitable for routine classroom demonstrations, electronics practicals and basic waveform analysis. The oscilloscope includes ALT triggering, TV synchronisation, X-Y mode and 10× sweep magnification as listed, supporting a range of signal observation and measurement activities.
The display is listed as a 6-inch rectangular screen with internal graticule, 8 × 10 divisions, where 1 division = 1 cm. The listed model number is CA620, with accelerating voltage listed as 2 kV for the 20 MHz model. The supplied feature list also references 40 MHz and 50 MHz variants, so users should confirm the selected model before final ordering. The maximum input voltage is listed as 400 V DC + AC peak at 1 kHz. Users must confirm probe rating, input coupling, signal source and safe measurement category before use.
The listed input impedance appears as 1 mΩ ±5%, 25 pF ±5 pF in the supplied data. This should be confirmed before final catalogue upload, as oscilloscope input impedance is commonly specified using megaohm notation. using, operate with damaged probes or connect to circuits beyond the instrument and probe ratings. Internal high voltages may remain hazardous even after power is disconnected.
This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the selected dual-channel analogue oscilloscope with probes only. Signal generator, microphone, microphone plug, additional probes, leads, power supply, calibration certificate, PPE and additional electronics accessories are not included unless specified separately.
LabChoice Australia supplies Analogue Oscilloscopes and electronics teaching equipment for school science laboratories, university teaching laboratories, technical training facilities and general laboratory environments requiring practical waveform display instruments.
