The radiometer power is measured by using the pulsin routine (see stamp 1 manual) to count the stamp clock cycles in a pulse from the the AD654 voltage to frequency converter. To enhance the accuracy we count up to 10000 10 microsecond cycles. During this time we may have several AD654 positive pulses so we return the total count w1 and the number of pulses counted w2. The host PC then calculates the power
