Re: More human oriented axis values

Thanks, I'm looking forward to the change. I need to say that for the first time when I added the cursors I couldn't find the measured frequency because the table with columns "time 1", "time 2", and "delta" does not contain it. It is placed at the right bottom. It's quite confusing for me as a newb...

Re: No way to align filtered signal segments

The 80 mV would help on signals with the peaks but not without them. I haven't tried an advanced trigger yet, but I will check this out for sure. Do you think that the digital trigger/alignment point is a bad idea? The aim is to align the edge in the visible signal on the screen, not in the invisibl...

Re: Math channel not visible

Yes, I changed the color (the pink one), but could find an alpha channel value input to set it transparent.
And the math channel is not visible since it is overpainted by the original signal from channel A.
Is it a bug?

Math channel not visible

Hello, I added a LowPass filter. I wanted it to be shown on top of the original signal, but it wasn't visible at all. See the picture. math_channel_overpainted.png The aim is to display the original signal (grayed / semi-transparently) and the emphasized math signal on top of that. Well, it doesn't ...

More human oriented axis values

Hello, Is it possible to display more human oriented y-axis values? I mean for instance 0 mV, 5 mV, 10mV etc. instead of the -0.366, 4.633, etc. I think the zero axis should be always there. Now it's quite confusing to find the middle and value units quickly. They change all the time :-( no_zero.png

No way to align filtered signal segments

Hello, I measured a signal on 2207B. noisy_signal.png It was very noisy, so I activated 10 kHz filtering. It turned into a clear signal, very nice feature! However, after that the trigger became useless since the trigger captures the signal before the filtering. See the picture. The trigger point is...

Re: 2 probes differs

The model is 2207B. Yes, that's in the 3% accuracy on DC values. I thought the channels should be somehow hw calibrated to be the same in the DC offset. I can manually fix that by "Axis Scalling Offset" set to "-0,30 %" in the probe B settings. So is creating a custom probe with DC offset set and al...

Re: First touch - vertical zoom and spectrum

1. How could I overlook that :-) Thanks! 2. What do you mean by FFT bin? Is it the sampling buffer? How is the FFT calculated actually? Is it just from the displayed sampling buffer or from all the buffers? If I want to just see any frequencies in an unknown signal, what is the best way to display t...

2 probes differs

Hi,
I measure the same signal with the same probes but the signal differs in a vertical offset.
Is it correct to set the "Axis Scalling Offset" to "-0,30 %" on channel B to fix it for ever or is there another preferred way? It is normal that the channels differ?

First touch - vertical zoom and spectrum

Hello, I've measured dc voltage after 3.3V regulator with PicoScope 2207B. I wanted to zoom just the area around 3.3V out to fullscreen, but didn't find out how. It was possible just horizontally. The zoom does not work vertically. Why? So I switched to AC mode. I wanted to see the frequencies prese...
