Unlike conventional peak reading or RMS meters, this system

was especially designed to provide the quick response time

essential to burst (popcorn) noise testing.

The test time employed is 10 sec and the 20 µV peak limit

refers to the operational amplifier input thus eliminating errors

in the closed loop gain factor of the operational amplifier .
