Effect of time-gating on measurement noise
The measurement noise on a time- gated measurement depends on the
time gate length. 100 averages are carried out every 1 µs of gate length.
The Noise- per- Sample contribution in this mode can approximately be
reduced by ÷(gate length / 10 ns) to a limit of 50 nW.
