Lab Scope / Meter 2-channel Bandwidth 3MHz Sample Rate: Up to 6 million samples/sec Scale range 0-100mV to 0-400V Sweep rate 50 microseconds to 20 seconds (5 min in GMM mode)

It’s slow but it’s an oscilloscope. It graphs electrical measurements over time. They sold CRT scopes on carts for years and years.

Maybe you should move the goalposts and demand FFT or higher bandwidth.
