PC Electrometer sampling interval is 100 �s. Each step in this graph of total charge indicates a linac pulse as measured with a 0.6cc chamber. PC Electrometer clearly shows the increase in linac pulse frequency as a function of dose rate. From 80 MU/min, the additional pulses are 1, 2, 3, and 4 for the respective rates of 160, 240, 320, 400.

Fast sampling makes PDD curves smooth and accurate when measured with the PC Electrometer and 1D Scanner. The PDD curve below is an un-smoothed ratio of Field to Reference, using 0.6cc Farmer type chambers.
