Detailed Description

Provides pulse delay as a function of amplitude for three choices of QIE bias setting. The "Medium" setting is used in HB and HE, while the "Slow" (and lower noise) setting is used in HO. All data taken from bench measurements of the QIE and plotted in Physics TDR Vol 1.

Not to be used for HF at this time (unlikely to have much effect)
