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
