About this product
This listing covers four models of the Rigol DHO800 series, sold from the Rigol flagship store, and the whole purchase decision is the model choice. The naming logic is public product specification: the last two digits give channels and bandwidth — DHO802 is 2 channels at 70 MHz, DHO804 is 4 channels at 70 MHz, DHO812 is 2 channels at 100 MHz, DHO814 is 4 channels at 100 MHz, and all four are 12-bit high-resolution scopes, which is the series' headline feature versus older 8-bit entry scopes. Pick channels by what you debug: 2 channels cover most microcontroller and power-supply checks; 4 channels let you watch input, clock, output and control line together. Pick bandwidth by your fastest signal: for serial buses like UART, I2C, SPI below 10 MHz a 70 MHz unit is ample; if you touch faster edges, take the 100 MHz models. Two things to confirm with the seller: the displayed price applies to which exact model (four models in one listing usually means per-model pricing), and which probes are in the box.
