Vertical Non-Storage
Deflection System
2212 Service Manual
Product Description
In
Non-Storage (Analog) mode, the vertical deflection system provides two
vertical channels with calibrated vertical scale factors from 20 m V to 50 V
with
a 10X probe (P6109),
and
2 mV to 5 V
per
division
with
a 1X probe
P6101A (optional). Both channels can be displayed simultaneously.
Each of the two channels can
be
displayed, scaled
and
vertically positioned
and
have their vertical coupling specified. Channel 2
can
also be inverted.
The
vertical channels have a
bandwidth
of 60 MHz
in
the
5 m V /DIV
thru
5 V /DIV position. In the 2 m V /DIV position
the
bandwidth
is reduced to
approximately 10 MHz.
Independent bandwidth limiting (to ±10 MHz) for each channel is also possi-
ble
with
the
BW
Limit switched on. You
can
limit one channel's bandwidth to
±10 MHz without affecting
the
bandwidth
of the other channel.
With the VARiable VOLTS/DIV gain control
(VAR),
you
can
increase the
deflection factor to overlap the next VOLTS/DIV setting. You can select the
following display modes:
CH
1,
ADD,
ALT,
CHOP, X-Yand
CH
2.
In
CH
1 or
CH
2 mode, only
the
signal
applied
to the
CH
1
OR
X
input
connector or to the
CH
2
OR
Y
input
connector is displayed
on
the crt screen.
In ALTernate mode, the display switches between
CH
1
and
CH
2 at the
end
of each sweep, showing
the
signals applied to
each channel alternately.
In
CHOPped mode, the display switches between
CH
1
and
CH
2 at a rate of ±500 kHz as
the
sweep is occurring to display
both channels simultaneously
on
the crt.
In
the
ADDed mode, the signals applied
to
the
CH
1
OR
X
input
connector and
the
CH
2
OR
Y
input
connector are algebraically
added.
In
X-Y
mode, the signal connected to the
CH
1
OR
X connector is
switched to the horizontal deflection
and
the
signal connected to
the
CH
2
OR
Y connector to
the
vertical deflection.
