General Product Description
Horizontal Display System
There are two 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, XlO, 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 Alternate Magnifier feature (ALT MAGN) to dis-
play 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 deter-
mines 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.
