ZET 302 USB oscilloscope. Appearance

Digital  USB oscilloscope ZET 302 is intended for observing high-frequency signals within the range up to 20 MHz. The use of 50 MHz analogous-digital converter and equivalent sampling mode increases the effective frequency up to 50 Msample/sec.

The operation is performed using the special software environment, ZETSCOPE, which simulates work with a desktop oscilloscope. Signals mathematical processing allows to observe the signal spectrum and assess signal parameters: average value, root-mean square value, peak value, peak-to-peak, signal frequency, period duration. Additional vertical and horizontal cursors facilitate the task of signal individual parameters measurement: build-up time, fall time.

Main Functions

of the ZET 302 USB Oscilloscopes


Over 20 parameters of the electric signal

Cursor Measurements

Determining a cursor coordinate value


work results to a file


Performing mathematical operations with signals


Viewing of signal shape and spectrum


Synchronous data retrieval

Flow Diagram

of the ZET 302 USB Oscilloscope

Two independent inputs are connected to controlled amplifiers. Signal passes through the amplifiers to the two-channel AD converter.

The digital signal processor reads the digitized data from the AD converters and stores those in the internal memory for subsequent transmission to the USB controller.
