It seems to be remarkably low currents. Are you sure that you had your DMM set to measure AC current?

But then, you should observe that if you measure current and voltage and just multiply the numbers, then you don't get the active power which is measured in Watts but the apparent power, which is measured in VA. As most electronic equipment does not have an ideal power factor (the current is not sinusoidal, or it is not in the same phase as the voltage), the active power is always lower than the apparent power.

To measure the active power properly, you need either a wattmeter that takes the phase difference and non-ideal waveforms into account, or a digital oscilloscope and some software and expertise to do calculations from the measured waveforms.

Typically, you can expect that a such item as a satellite receiver will draw between 1 and 10 W in standby.

Hi guys:i bring up this topic because i came across a forum that discussed the power consumption of Satellite Receivers on Standby,and somebody there said that the receivers consume as much power if receiver stays on standby as it consumes when turned on.So i went ahead did some calculations on my 322 receive,and came up with these numbers,i may be wrong on my calculations correct me if I'm wrong!.
With my Fluke 87 measured 0.236miliamps turned on,and 0,226
in standby,

on standby 120v/0.226=530 Ohms,120x120=14.400/530=0.027watts.
turned on 120v/0.236=508 ohms,120x120=14.400/508=0.028watts.

i don't know if these #s are correct, but if they are than the power consumption is very low and is not that bad,if not than this receivers are not green at all,because no matter what kind of equipment they shouldn't waist as much energy on standby as in on mode.So anybody here is an expert enough to refute my numbers?
