Looking for recommendations on power supply with current meter to profile power consumption

<***>

Hi!

I’m designing an IoT device and I need to characterize its power consumption.

I would like to provide power and measure it through the same device and be able to log the device’s current for certain amount of time to then analyze the behavior at the different states that the system operates in.

The sleep current is in the 5-10uA range and the max current I am expecting is of peaks of 250mA when transmitting.

We currently have an old 34410A DMM but we are trying to get something newer and that would both supply and measure for ease of setup.

Ideally it would be not too expensive (max $600) but any recommendation is appreciated.

Thanks
