R&S RTB2004 front USB 5V power output?

(1/5) > >>

gdr771:
Does anyone know how much power the front USB connector on a RTB2004 can output?  I have a usb-powered Micsig DP10013 differential probe that seems to draw 90mA at 5V (according to a cheap USB meter), but it keeps resetting every second unless I power it directly from a wall adapter.  (I was also not able to power a keyboard or mouse from the front connector, so I'd like to know if this is a fault or expected.)  Thanks!

tooki:
The user manual expressly claims USB keyboards and mice are supported (though the datasheet does not).

Hydron:
Mine lets me power two of them at the same time, but you have to plug them in sequentially otherwise the inrush trips the scope

Rydda:
I usually have a usb rf dongle ( which seems to draw <10mA) on the front panel with no problems. A Micsig DP1007 (which draws 240 mA) also works OK.

langwadt:
if it is USB you should be guaranteed atleast 100mA
