Rigol DHO1204U oscilloscope
Details
The Rigol DHO1204U is a 4-channel oscilloscope and the 200MHz bandwidth model in the DHO1000U series. Whereas many oscilloscopes use an 8-bit vertical resolution, this product comes with a 12-bit resolution to reduce quantization uncertainty and in turn improve signal fidelity and analysis capabilities. This can even be increased to 16-bit in high-resolution mode, enabling even higher detection of variations in incoming signals.
This product features a large 10.1" touchscreen, 8GB of internal memory and a high capture rate. With UltraAcquire mode it is possible to increase the capture rate up to 500,000 wfms/s. Multiple interface options include USB 3.0 ports (2x in the front and 1x in the back), LAN, HDMI, Pass/Fail and Trigger Out. LAN web control is also supported which allows for the operation interface to be displayed in a web browser.
The oscilloscope offers extensive measurement and analysis possibilities. Up to 500,000 frames with data can be recorded and played for extensive analysis. In addition, the product has a very low noise floor, making measurements on very small signals possible and resulting in cleaner signals.
Please note, the images are of the DHO1204 model. Other 4CH models have a similar layout.
