Pico Technology has introduced its PicoScope 3424 PC oscilloscope that features four channels,12-bit resolution, 20 MSa/s-sampling rate and a large 512 k memory buffer. Its USB 2.0 port is easily connected to ancillary equipment to enable rapid display updates. The port also powers the instrument, eliminating the need for an external power supply.

The model 3424 also has a large memory buffer that enables capturing long-duration signals at its top sampling rate of 20 MSa/s. It exhibits 1%-voltage accuracy and 100 ppm time-base accuracy. Time bases from 500 ns/div to 50 s/div and voltage ranges from +/-20 mV to +/-20 V make it suitable for a wide range of applications, including general analog, audio and digital design and repair. With its 12-bit resolution, the oscilloscope produces high-quality waveforms that can be vertically zoomed to reveal even higher levels of detail. This resolution gives the instrument a 72 dB dynamic range, enabling it to detect low-level harmonics when used in spectrum analyzer mode, in applications such as noise and vibration analysis.

The software supplied with the PicoScope 3424, along with its 32-bit Windows driver, supports numerous third-party applications and its oscilloscope, spectrum analyzer and multimeter functions transform virtually any PC into a powerful data logger that can export data to a spreadsheet or display it as a graph, in real time.
