A Memory and time base settings
B Clock base
This setting must be set to "External".
C Unit
Normally during rotating measurements this would be "Degrees".
D Unit scaling and Clock scaling (Scale result)
These two settings define the relation between the external clock pulses
and the units. The final setting is the division from these two settings. The
setup uses two settings to ease the setup process and avoid rounding
errors whenever possible.
For example using a 1500 clock pulses per 360 degrees cycle then:
Unit scaling = 360
Clock Scaling = 1500
