Value
An integer from 1 through 8, depending on how many
oscilloscope cards are installed as a single unit (chained
together).
a real number defining the voltage at the center of the
display. The offset range is as follows (for a 1:1 probe
setting):
Vertical Sensitivity Vertical Range
4 mV - 100 mV/div 16 mV - 400 mV
>100 mV - 400 mV/div >400 mV - 1.6 V
>400 mV - 2.5 V/div >1.6 V - 10 V
>2.5 V - 10 V/div >10 V - 40 V
an integer from 1 through 1000, specifying the probe
attenuation with respect to 1.
a real number specifying vertical sensitivity. The allowable
range is 16 mV to 40 V for a probe attenuation of 1. The
specified range is equal to 4 times Volts/Div.
