Yes, I’ll just trust the AI to help me fuck around with grid voltage levels.
With google search results becoming so poor, I guess I need to look into kagi or duck-duck. Pain in my dick, motherless goatfucking, horsehit-happy asshole, corporate varmints gotta fuck it all up for more profit. I’m tired, yo.
I asked Andi at least it suggest to contrast it by yourself in the mencioned sources after the summary
Rigol DS1202Z-E Maximum Input Voltage
The Rigol DS1202Z-E has a maximum input voltage of ±400 V (DC + peak AC) at the 1 MΩ input impedance setting, according to the EEVblog forum, which references the official Rigol performance verification procedure manual.
Note that this is a DC-plus-peak rating. At higher frequencies, input voltage limits typically derate, so the ±400 V figure applies at low frequencies. The EEVblog thread specifically discusses this frequency derating question, making it the most relevant source for anyone probing near the limits.
The DS1202Z-E is a 200 MHz, 2-channel oscilloscope on Rigol’s DS1000Z UltraVision platform, per Rigol NA. It includes deep memory, serial decode, and FFT.
For the full derating curve and exact specs at higher frequencies, the EEVblog forum thread is the best starting point, though the site was returning a CAPTCHA at time of search. Consulting the official Rigol DS1202Z-E datasheet or performance verification manual directly will give the authoritative derating table.
