USB Oscilloscope Connection
Posted: April 5th, 2022, 11:24 pm
I have purchased 7055-D to use with a USB power Oscilloscope (PicoScope 4262). I am struggling to get the Oscilloscope to function and want to know if there is a check-list of options to try? The Oscilloscope appears in device manager when plugged directly into laptop, but doesn't appear when plugged in via 7055-D. There is some flashing on the light of the 7055-D but not sure what exactly the flashing is to correlate with 7055-D data sheet. The laptop is a Dell Precision 7510 and I believe all the USB ports are USB 3.0.
1) I believe the PicoScope 4262 is USB 2.0 powered and therefore the power is limited to 500mA, this should mean the 7055-D should be able to power without aux power supply?
2) Would any aux power supply be sufficient to try for secondary aux power options, if this worked do you have a recommendation of low output noise power supply?
3) Would using a USB C to the USB 3 type B connector make any difference?
4) Does the Laptop need to be plugged in for the correct voltage stability on output?
I am happy to have any other suggestions too.
