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.
