| KS MSOX3000T push for 50% trigger strange behavior/bug |
| (1/1) |
| electr_peter:
Pushing trigger level knob for "Push for 50%" functionality works a bit strange on Keysight MSOX3000T. With only one channel enabled and in auto run mode, pushing trigger knob results in momentary turn on of all analog channels (channel buttons light up briefly), momentary display all analog traces on screen, momentary drop in sample rate (due to all channels enabled) and finally 50% trigger setting for enabled channel. Other channels remain turned-off, turn-on is only for a brief moment. Is this expected behavior or a bug? User manual states 50% action is valid only for displayed channels --- Quote ---You can push the Trigger Level knob to set the level of all displayed analog channels to the waveform's 50% value. If AC coupling is used, pushing the Trigger Level knob sets the trigger level to about 0V. --- End quote --- |

Have you done a Default on the chance some hidden settings made it behave this way ? To be fair you should state the firmware version installed. |

Yes that is how it works.. Why, I have no idea. It doesn't matter though, because it is quick and does it's job. |

FW version 7.55.20220718 (released on 2022-07-29). Same behavior was noticed after "Default Setup", also with various analog channel combinations. Not every time other channel traces are shown on screen, but left side axis goes through other colors every time. This is not a bug IMO. It seems that "Push For 50%" functionality is a subset of "Auto Scale" functionality. Presumably you want the scope to setup itself based on input signals, so "Push For 50%" configures all analog channels triggers to middle of the waveform (so that if trigger source is changed, scope still triggers), irrespective if other channels are turned on or off. KS manual should read: --- Quote ---You can push the Trigger Level knob to preset the level of all analog channels to the waveform's 50% value. --- End quote --- |

My MSOX4000 does the same. So this seems to be a normal behavior for these Keysight scopes. |
