Function Recommended Use
13
Variable
(CAL)
Provides continu¬
ously variable de¬
flection factors
between calibrated
positions of the
VOLTS/DiV switch.
Reduces gain by at
least 2.5:1.
Match signals for
common-mode
readings. Adjust height
of pulse for rise-time
calculations.
14
AC-GND-DC In AC, blocks dc
component of
signal. In GND,
gives reference
point and allows
precharging of
Input-coupling
capacitor. In DC,
couples all com¬
ponents of signal.
Select method of
coupling input signals to
the vertical deflection
system.
1
CH 1 OR X
CH 2 OR Y
Provides for input
signal connections.
CH 1 gives hori¬
zontal deflection
when SEC/DIV is
in X-Y: CH 2 pro¬
vides vertical de¬
flection.
Apply signals to the
vertical deflection
system.
16
HORIZONTAL
POSITION
POSITION moves
traces horizontally.
Control trace positioning
In horizontal direction.
17
MAG
(X1-X10)
Selects degree of
horizontal magni¬
fication.
Examine small
phenomena In detail.
Extends sweep speed to
10 ns/div.
18
SEC/DIV Selects time-base
speed.
Set horizontal speed
most suited to require¬
ments.
19
Variable
(CAL)
Provides continu¬
ously variable un¬
calibrated sweep
speeds to at least
2.5 times the cali¬
brated setting.
Extend the slowest
speed to at least
1.25 s/div.
