Definition
The absolute value in V of the magnitude of the analog signal
(i.e. one sided rating)
The peak to peak signal magnitude in mA of the analog signal
The ratio of A channel peak analog signal to B channel peak analog signal
waveform or its compliment.
The offset in V from the mid-point of the analog peak to peak signal to zero current
The number of electrical degrees between a transition in channel A and the neighboring
transition in channel B. There are 4 state per cycle, each nominally 90°e. The transitions
are determined by where the analog signal crosses the Zero point
The deviation in electrical degrees of each state width from its ideal value of 90°e.
The number of electrical degrees that an analog output is greater than zero during one
cycle. This value is nominally 80°e or ½ cycle.
The deviation in electrical degrees of each pulse width from its ideal value of 80°e.
