Hi,
I was wondering whether a 5243A (or 5244A) running with 2 input channels at 125MS/s could be powered up with a single USB ? I am hoping that the higher power requirements (1A or more) may only be required for the highest sampling rates and # channels. Thx

Would you have some specs on the current consumption though vs load on the scope ? The digitizer is meant to be included with a system that has other requirements and we can't really guess our way around. It would be better to have a sense of the current draw beforehand.
• The sampling Rate (higher sampling rate will draw more power),
• The signal you are putting into the device,
• voltage source to the USB (The lower the voltage supply the higher the current draw will be),
• If the device is waiting for a trigger and
• The resolution settings.
Unfortunately we do not know how much this will vary the power draw.
While it would be possible to carry out tests, and work out the power draw, the number of combinations for a single scope model, and the number of models we have in our range, would make this impractical.
But if you can post here or email support@picotech.com with the settings you would be looking to use and the signal you would like measure I would be able to test the 5243A (or 5244A).
• 5243b, sampling Rate: 125 MS/s, 15 bits res.
• 2 inputs: one on ~ 2V range, one on 50mV Range,
• voltage source (if enough current available) : USB: 5V (PC)
• Waiting for triggers coming in at 512 Hz. # samples on each channel to acquire for each received trigger: min 800 ; max 6000.
• acquisition type: buffered: all triggers acquired to internal buffer first, then transferred to PC.
• # triggers: min 500, max 4000
