Thank you. That's interesting. Ignoring the warmup time, which would be a small fraction of 48 hours, if one assumes 30 mA for 48 hours, that's 1440 mA hr. So 15 x 1.2 V Nickel Metal Hydride AA cells would easily do that, as they are available up to about 2400 mA hr. It means it is practical put a 3458A reference board in a box, and ship it to someone else for measuring whilst keeping is powered up in transit.
