I know that Voltage tool can drive up to 50mA. However, I could not locate any documentation on current drive capability of Wavegen tool. If variable DC voltage is applied through Wavegen tool, what current it can drive without degrading its output voltage? Any help in this regard would be highly appreciated.
The final output driver for the AWG channels is the AD8067 amplifier configured in
the inverting mode with an 11 K feedback resistor and a 1 K input resistor.

Which has a link to the detailed data sheet. The spec table should provide any
performance data you need for your specific conditions.
