OP is a beginner... --- End quote --- The probes supplied with the DHO800 are clearly labelled: Saying 10x300=3000 is a mathematical fact. Nobody was asking about measuring 3000V, nobody was saying it was OK to do so. |

This divides the voltage by 10 inside the probe. ie. With 10V input, only 1V will arrive at the 'scope. --- Quote from: mkosett on November 28, 2023, 05:03:20 am ---Is the 1054Z more resistant to getting destroyed than the dho800? --- End quote --- Both are 300V rated. With 10x probe it takes 3000V to overload it. --- Quote from: mkosett on November 28, 2023, 05:03:20 am ---And what about repairability, which is better self repairable than the other? --- End quote --- Neither are very repairable. The thing most likely to fail is the power supply. The DHO800 uses an external USB-C for power supply and can run off suitable phone chargers, etc. You can even use a USB powerbank to power it from battery. --- End quote --- This statement is totally irresponsible, especially when responding to someone that identifies as a beginner, and likely and open door for liability!! The PV3150 probes provided with the DHO824 are rated Cat II for 300V at 10X, and 150V at 1X as are most generic scope probes!! Only specialized scope probes rated for higher voltage should be applied beyond the 150/300V ratings, this is quite dangerous lethal territory!! Hope folks recognize this, and also recognize the source of such dangerous misinformation :-- |
| Mechatrommer:
he (that statement) is correct though if using specialized probe rated for 3KV at 1/10X... but not for your normal joe rigol probe. |

Since I have been looking at 800 up through 2000 series, the DHO804 is bare minimum to buy, you can then "upgrade" it to the 814. Also limited to 100MHz spec, -3db should be somewhere near 180MHz. Albeit single shared ADC. As for mixed signal, sorry just have to comment on it, the SDS1104X-E is on sale now and comes with digi bundle SDS1000X-E-FG and SDS1000X-E-16LA for $475. This SDS can also be "upgraded" to 200MHz. Dual ADC. Each has their own learning curve and are different, but nothing drastic. |
