HEIDENHAIN PWM 8 Operating Instructions Manual page 48

Analog Output signals (~ 11 µApp/1 Vpp)
Prepare the oscilloscope as described below:
•
Vertical deflection
– Switch channels A and B to chop mode (CHOP).
– Set the deflection coefficient (Sensitivity) of the
channels A and B to 0.5 V/DIV (11µApp), 0.2 V/DIV
(1Vpp).
•
Horizontal deflection
– Set time coefficient (Time basis) to 0.5 ms/DIV.
•
Triggering
– Trigger automatically (AUTO)
– Trigger Channel A
– Trigger positive edge
•
Calibration
– Switch the input coupling switch (AC/DC/GND) of
the channels A and B to GND ( ç or 0)
– Use the Y-position potentiometers of the channels
A and B to shift the electron rays congruently to the
center of the screen (fig.)
– Switch the input coupling switch (AC/DC/GND) of
the channels A and B to DC
