Quite an expensive thing. What does it have that is missing from, for example, a HP/Agilent/Keysight 66319B or 66319D?
Commander_Spock:
unsure my answer is correct but we have several project related to  iot related stuff where power is one of the critical point. imagine an equipment where a singel cell battery should be enough for 5 to 10 years of operation.
we are not interested in how this battery is behaving but we are interested to know how our equipment use power provided by this power source. we need to know that when we do "this" on our equipment we eat "this" power from our power source... with this info our goal is to change our software to use less power...
for example imagine a small drone that look like a jelly fish, it do not swim (required too much energy) but it only follow sea current for years in the open sea, measuring pollution and collect data at different location and depth... every x hours it send some data wirelesly...
this is one of the iot "object" (internet of things) project we are investigating. imagine the same with same sensor but at a fixed location each miles in each rivers of the world ?   
Put this "object" every quarter miles in each street of your city (diretly in the road concrete) and until battery last it will send useful data for years...

here the need is to check that our application software running in this "object" cpu is cleverly designed to minimize power consumption in order to decrease cost of ownership/operation (this object cost wont change but if it can be used twice longer total cost of ownership will be twice smaller)

alll of this kind of "object" will use always less than 5v ...

all this show that yes we need to buy something like the qoitech solution (or something equivalent) but their software is not answering our need at all and a labview/mathlab driver is the minimum required for our automatic tests scenarios where labview/mathlab send a signal to our "object" simulating an evevnt or a measure on a sensor and our software in the object cpu wake up and process this info then go back to sleep.... during all this the qoitech can measure the power comsumption... with these info we can estimate the battery expected life and we know if we are good or need to find better solution that eat less power... yes these test will run 24/7 with various scenario all defined in labview/mathlab that is coordonating everything on this tested

now if somebody has a better idea for our testbed i will be very happy to listen
glarsson:
Have you looked at a used 66319? This is exactly what this thing is designed to do. It can even simulate a battery with configurable internal impedance and can also sink current to simulate rechargeable batteries.
Commander_Spock:
will take a deeper look but its almost  7 times more expensive than qoitech and keysight website announce it is not available in europ due to rohs compliance issues with european regulations
glarsson:
That's why I wrote "used". It can't be sold new due to RoHS.

It's an old model but there aren't many alternatives. The Otii appeard as a cheaper option but with a subscription.
