State - Pulse Data Analysis
Enables pulse data analysis. The measurement is started with the "Start Cont." button
in the main measurement diagram.
Remote command:

Base - Pulse Data Analysis
Selects how the threshold parameters are calculated, either voltage related or power
related. The voltage-related parameters represent the normal case, as the usual repre-
sentation when defining the pulse parameters (rise/fall time, pulse width) is U(t). To
achieve a display with equivalent power-related values, the voltage-related threshold
values must be converted (squared) (see example in table below).
Distal Mesial Proximal
Voltage related: 90% 50% 10%
Power related: 81% 25% 1 %
log. Scale (for example):
(approximately, difference between top- base
power > 30 dB )
