This “beauty” appeared on my desk today. Just testing & playing with it. I used the arb sig-gen of a PicoScope 2204A for generating a unpleasant test-signal. Trying to trigger on it was “interesting” :-)
The sender was the current CEO of LeCroy, Thomas H. Reslewic. I’m glad they have finally taken action. I was offered a full refund. I hope they will also look into all the WaveAce 224 issues I’ve documented so far … Continue reading
This is a ‘close relative’ to the ‘eternal boot screen’. It is also caused by the all-mighty triggering system, which governs the whole oscilloscope – even when it shouldn’t. One of the most annoying things is that this can block … Continue reading
Will it ever end? How many bugs are there still to be discovered… A word of warning: there will be some strong language in the post. If anybody affiliated with Lecroy should read this, please feel offended – not as … Continue reading
Another quirk. I seem to have a talent to upset this device. Showing a signal that isn’t there should not happen though.
Automatic cursors are supposed to show what and where stuff is measured on a waveform when automatic measurements are used. This is pretty useful, if it works as expected. Suffice to say that it doesn’t always do that – unfortunately.
Got the ‘pulse-trigger’ to trigger. This time I don’t care if the set pulse-length is actually accurate, I just wanted it to trigger on the ‘thing’ and it did. Fine – happy happy joy joy! Then I felt like moving … Continue reading
I managed to damage the alligator clip on one of my probe’s ground cables. It was probably a bad one and it fatigued. I replaced the alligator clip with one I found in a box. During this procedure it turned … Continue reading
Where art thou? This time I have discovered issues that are trigger-related, but more suitably filed under “general displaying issues”. Still using the “1.01.01.18R2” firmware. Just have a look at the video. No more words…
Oh boy, this thing can’t even count correctly… or since when is 7 = 9 ? Pulse-Trigger: I call that a bug.
To see what of the trigger system of the WaveAce 224 works and doesn’t work (as I expect it), I’ve made a little device, which shall from now one be called DSO-T.
This is the first post regarding the Lecroy WaveAce 224 DSO. As it currently seems I have material for at least a few short posts. Currently I’m having issues with one important knob and the triggering system.
I was having problems with the “led ring” boards. Their internal oscillators were not ticking with the same speed and required constant re-syncing. I tried to improve the situation by recalibrating by adjusting the OSCCAL registers. Recalibration can be done … Continue reading
Maybe you remember my last post about the Jyetech oscilloscope and it’s weird behaviour. Not all of them are strange, as the free replacement DIY KIT I received from them works fine. At that time I suspected a sick ATmega64 … Continue reading
The symptoms since a firmware upgrade (and downgrades, re-upgrades…): strange characters on the display for SEC/DIV system freezes +/- buttons are ignored (but still work physically) the ADC chip doesn’t get a CLK signal during a freeze My theory: The … Continue reading
I bought the DIY KIT at seeedstudio recently, as I needed to feed my soldering obsession. Here are some images of the KIT coming right out of the box: I had to use my milling machine, because the front panel … Continue reading
