Tho what does irk me is that the X3000 has the same buttons on the front panel as the 6000 but they are in different locations. This often results with me hovering my finger in front of the wrong part of the front panel as i frustratingly look for the button i want to press. Oh and having a LED for AC BW 50Ohm next to the channel would be nice to have like it was on the 6000 (Seen lots of confused coworkers due to AC or BW limit being on without them knowing). --- End quote --- LOL that sounds familiar... I personally miss the most physical LED for trigger event. To the point that I connected a low power LED and resistor to trig out and sticking it out in the front. --- End quote --- I like that idea. Creative! :) |

Are you blind man? 8) --- End quote --- [ personal insults by tv84 deleted ] now you come to a 1-year old thread to call another one "blind"? --- End quote --- Seriously? Please tell me if your think they look the same: |

I obviously can't share numbers, but the AFR/MTBF is easily 2x better than a lot of our other gear. --- End quote --- The PSU actually looks nice. https://youtu.be/9KcOQsVxtoU?t=475 --- End quote --- Also, people think of Aishi capacitors as low grade, but they are one of the best non-Japanese capacitor manufacturers there. On a well designed flyback SMPS the ripple current through those output capacitors will be small, as the switching frequency is quite high nowadays (likely 150kHz or above) |

It's been quiet on the threat for a while, but as this seems the most general threat on the Keysight InfiniiVision 1200 X-Series and EDUX1052A/G oscilloscopes, let me post some question... When using the FFT mode, the manual (Fourth edition, September 2021, p. 61) explains: * FFT units will be displayed in dBV when channel units is set to Volts and channel impedance is set to 1 MΩ. * FFT units will be displayed in dBm when channel units is set to Volts and channel impedance is set to 50Ω. The issue is that the channel impedance on this scope cannot be set to 50Ω. Is this an error in the manual (and this piece of text was copied from a more sophisticated Keysight scope)? PS some of my other oscilloscopes allow dBm display in FFT mode and thereby either assume there is an external 50Ω load (Rohde & Schwarz RTB2004), or allow you to set the value of the external load (Siglent SDS2000X Plus). But on the DSOX, I cannot get it to display dBm at all (and if I would, it's not clear what impedance it is assuming). |
