Tektronix 2212 Service Manual

Product Description
Horizontal Display
System
1-4
The 2212 has two different horizontal display systems :
Horizontal Non-Storage Display System
Horizontal Storage Display System
You can horizontally position
the waveform with the horizontal
POSITION knob.
The
Xl, X10, X50 magnifier switch magnifies the horizontal display
10 or 50 times around the center vertical graticule line.
Horizontal Non-Storage Display System
In Non-Store mode, the 2212 provides a calibrated sweep speed range
from
0.5 s per division to 0.05 µs per division. You can use the variable
timing control
(VAR) to increase the non-store sweep time per division
by a factor of
up to 2.5 times the calibrated time per division, as selected
with the SEC/DIV switch.
You can use the Al temate Magnifier feature (ALT MAGN) to display the
magnified and unmagnified sweep alternately on the crt screen
in Non-
Store mode. You can reposition the unmagnified sweep vertically with
the Trace Separation control
(TR SEP) in the ALT MAGN mode.
Horizontal Storage Display System
In Store mode, the 2212 provides a calibrated sweep speed range from 50
s to 20 µs per division. The SEC/DIV switch setting determines the
acquisition and display modes, sets the sampling rate and establishes the
time scale factor of the displayed waveform.
The maximum sampling rate is
20 megasamples per second
(20 Ms/s) with a stored record length per waveform of 4096 points for
single-channel and dual-channel acquisitions. All 4k points are visible on
screen at one time.
One waveform set
(CH 1 and CH 2), 4k record length each, can be stored
in the reference memory as a refernce waveform, giving a total 8k record
length. Previous stored data
in the reference memory is overwritten. A
reference waveform may be recalled
for display and comparison with the
current acquisition waveform.
