--- Quote from: E-Design on November 25, 2019, 10:24:30 pm ---There is an internal signal path difference based on selection 10M or Auto. --- End quote --- Can you reveal the details? What is the difference? What is the input impedance in Auto mode? Does the device have the ability to work with an input impedance of 1 GΩ for the ranges 100V and 1000V ??? |

New firmware 1.7.0. Trying to write a large contiguous buffer (8 000 000 samples) at a time: Settings: Digi V + [Freq=1MHz] + [Aperture=1mks] + [count = 8,000,000] When time-critical processes are not implemented on the hardware, but are given to programmers, it’s a disaster :( When the product is more than 5 years old. But he still cannot do a simple operation - write a buffer of a given size with a given frequency. But on the screen you can run the watch and other toys. :palm: |

For 1000V, the cutoff frequency is 17.5 kHz. --- End quote --- I figured out different cutoff frequencies for 100V and 1000V 17.5 kHz available for: 1000 V + 10 MΩ 1000 V + Auto 100 V + 10 MΩ 7.5 kHz becomes at a combination of parameters 100 V + Auto Why, when choosing the input resistance Auto for the range of 100 V, the strip changes I do not know. This is some kind of mystery. I tried to measure the input impedance for Auto and for 10 MΩ = 10 MΩ without changes. Something inside limits the band. |
