There's no example in the manual and I never could really think of a situation where it would be useful. (Obviously it is useful, or it wouldn't be a feature!) --- End quote --- It allows capturing only the relevant parts of a signal around the trigger points and usually produces a much higher waveform acquisition rate without the disadvantages of DPO mode. |

To my surprise - the voice control on the Keysight scope is an awesome feature that I use all the time. When my hands are delicately trying to probe two tiny points - the voice control can save my ass. Start, stop, scaling, and more. Super handy and works with a normal voice and all the fans on my bench going full blast too. I would give up touch screen before voice control. |

Can't remember what the waveform rate was for the original but I believe it was somewhere in the 250k wfms/s region. The important bit however was that it was not just one large number at a specific setting (as with InstaVu/DPO), it reached high update rates in almost any setting. --- End quote --- Hmmm - you need to be more specific regarding wfrms/s because when dave reviewed an older HP 54622 (2000 vintage) with MegaZoom it says something about 25 million vectors per second ??? Go to 8:40 where dave tests the actual update rate - a measily 520 wfrms/s at best :-- |

To some degree, this is a matter of personal preference, but it also depends on the waveform. · You will probably operate the oscilloscope most often with vectors on. Having vectors on slows the display of the oscilloscope, thus works better for slower sweep speeds, peak detect, or average displays, and signals with stable triggers. · Having vectors off works better for fast sweep speeds, normal displays, or unstable triggers. Complex analog signals like video and eye diagrams show more intensity information with vectors off. Turn vectors off when the maximum display rate is required, or when highly complex or multi-valued waveforms are displayed. --- End quote --- |

Did the modification removing R1064 and 4 caps , but no difference with the banner |
