Martyn, Thanks for clarifying the specification of the Pico USB cable. Email to support will follow shortly. Regards, Martin. (p.s. regarding spamhaus blacklist. As discussed in another thread posts are accepted after cycles of Preview/Submit but it typically takes me 5-6 attempts. I am in that cycl...

Hello RAF96, I am hoping you still get alerts from the Pico forum. I too am trying to understand grounding in the operation of Picscope and USB. You say; "I am acutely aware of the Pico warnings about parallel grounds when a 2408 is also attached to the same PC by USB". Can you tell me where to find...

Benno,
Thanks very much for testing your cables.

Regards,
Martin.

USB Cable Does the shielding of the USB cable play a significant part in the operation of the Pico oscilloscope? In the PicoScope 2000 Series Quick Start Guide it says; "CAUTION To prevent measurement errors caused by poor grounding, always use the high-quality USB cable supplied with the oscillosc...

Thanks Benno,

I have taken two lessons from this.

1. As you say, always check before connecting anything.
2. Although USB is a mature technology you do not know what you are getting. I now regard every USB hub as a 'black box'. You do not know what is inside.

An update. How could Picoscope affect the PC (NUC) monitor? The monitor (BENQ) itself has a 4 port USB hub, to which my keyboard and mouse are connected. The monitor USB is connected to NUC USB. Picoscope connected to NUC. Arduino UNO auto reset Even though there is now no potential difference betwe...

New user encountered a problem. I have a work-around but would like advice. I am using a Picoscope 2204A to examine a signal on a shield mounted on an Arduino UNO. In use the Arduino is connected to and powered from a Raspberry Pi by USB cable. I am running Picosope on a separate Intel NUC, 'scope t...
