Summary of EEVblog 1503 - Rigol HDO4000 12bit Oscilloscope TEARDOWN

00:00:00 - 00:25:00

The video deconstructs the Rigol HDO4000 oscilloscope, revealing its various components and discussing their quality. The author notes that the noise front end is not as good as one would expect for a product at this price point, but that the HCL 1000 series oscilloscope, which is scheduled to be released soon, should be much cheaper due to its lower bandwidth.

• 00:00:00 The Rigol HDO4000 12-bit oscilloscope is very powerful, but it is very loud and whiny. The front end is made up of many high-end components, and it is easy to upgrade the fans. The Die-Cast case is beautiful.
• 00:05:00 The video details the installation of the Rigol HDO4000 12-bit oscilloscope. The front end is made up of identical boards, each with a heat sink and polyswitch protection. The main processor is a Xilinx RT8847 or 4471.
• 00:10:00 The Rigol HDO4000 12-bit oscilloscope is broken down into its various components, including the front end, Asic, and relay. The front end uses Japanese Fujitsu relays, which are superior in terms of contact spring for high frequency characteristics.
• 00:15:00 The Rigol HDO4000 12-bit oscilloscope was deconstructed, revealing that it has two differential pairs of outputs for signal handling. The high-power front end is a 272-op-amp precision dual op-amp, and the sample-per-second ADC is a Centaur chipset.
• 00:20:00 The Rigol HDO4000 12bit oscilloscope is being dissected in this video, focusing on its power supply, CPU, and touch screen. The rock chip used in the oscilloscope is from an older generation, and there are two buttons on the board that are not marked. It is unknown what they do.
• 00:25:00 In this video, the author takes apart the Rigol HDO4000 oscilloscope, noting that the noise front end is not as good as one would expect for a product at this price point. He also notes that the HCL 1000 series oscilloscope, which is scheduled to be released soon, should be much cheaper due to its lower bandwidth.
