The absolute value in V of the magnitude of the analog signal
(i.e. one sided rating) sitting 1.65V voltage offset reference
V
Analog peak to
peak Voltage
VppA VppB
The peak to peak signal magnitude in V of the analog signal
V
Analog peak to
peak ratio
VppA/VppB
The ratio of A channel peak analog signal to B channel peak analog
signal

Analog Crossing
Vx12, Vx34,
Vx56, Vx78
The intersection in v of the A channel analog waveform with either the
B channel analog waveform or its compliment.
V
Analog Offset
Voltage
Voffset A
Voffset B
The offset in V from the mid-point of the analog peak to peak signal to
1.65V voltage offset reference
mV
State Width
S1, S2, S3,
S4
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 900°e. The transitions are determined by where the analog
signal crosses the Zero point

S1,
S2,
S3,
S4
PA,PB
The deviation in electrical degrees of each state width from its ideal
value of 900°e.
°e
Pulse Width
The number of electrical degrees that an analog output is greater than
zero during on°e cycle. This value is nominally 1800°e or cycle.

Pulse X Width
Pulse X width A is the number of electrical degrees that analog A output
is greater than analog B bar output during one cycle. Pulse X width B is
the number of electrical degrees that analog B is greater than analog A
during one cycle. This value is nominally 1800°e or cycle.

connecting adjacent upper and lower crosspoint voltages to the
difference between crosspoint voltages
