I
B. DEFLECTION COEFFICIENT
The deflection coefficients aÍe adjusted by means of
the attenuator ("mY /cm" - "V /cmo'). These deflec-
tion coefficients ate calibrated if the continuous gain
control is turned fully clockrrise (indicated with
"cAL.tt).
C. 66BAI\DWIDTII''
The maximum
bandwidth
is obtained by setting
switch "BANDWIDTf,I"
to position "FULL".
In the
most sensitive position of the attenuator, a noise band
having a width of a few millimetres will appear on
the screen.
In
position
"0... L00 kc/s"
of
switch 'BAND-
WIDTH",
the bandwidth of the amplifier is limited
to the indicated value at which the noise can be
neglected.
Note: The noise is also reduced while maintainiog
the maximum bandvyidth, by reducing the sen-
sitivity of the amplifier by means of the attenu-
ator.
D.

The picture can be shifted in a vertical direction with
the aid of knob "SHIFT".
E. "GAIN
AI)J.''
The deflection coefficients of the unit can be checked
by applyrng the calibration voltage of the basic oscillo-
scope to the input of the unit. If the deflection co-
efficients do not correspond to the values indicated
on the text pl.ate, the coefficients can be corrected
by means of settiog "GAIN".
Note: With this adjustment, the continuous gain con-
trol should be turned fully clockwise, ("CAL").
