Insert a low-pass filter (47-kilohms/0.01uF)
|
between the probe (10:1) and scope input (CH-Y),
|
set the oscilloscope into X-Y mode.
Connect the probe to TP-7, and verify the ground
level in CH-Y input. CH-X is not used. While
scanning to forward direction, adjust VR7 to ob-
tain a positive voltage depending on the mirror
rank. Mirror ranks and set points are shown below.
Disconnect the low-pass filter, and reset the oscil-
loscope to normal
mode.
