Adopt ARM Cortex-M3 processor (STM32), and include a 2.4-inch color TFT display screen.With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
Upgrade version of DSO311 and the test performance is more stable.Used for secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.
With Auto/Normal/Single trigger modes, easy to capture the moment waveform.Available rising or falling edge trigger and it runs faster than DSO138 & a good handle of data.
Observable previous waveform before trigger(negative delay).Can freeze waveform display at any time(HOLD function).
The SMD has been soldered, more suitable for electronic beginner.TFT controller recognition function with cool black case, which makes it convenient to use in teaching and testing..
