Horizontal Operation
This section discusses controlling the horizontal aspects of your
signal. The knobs and switches to do this are situated in the
HORIZONTAL section of the front panel, which is enclosed within
grey lines (see Figure 5-3).
The 2212 Oscilloscope can be used in two different horizontal
display modes:
1. Horizontal Non-Store Display Mode
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.
The Xl, X10, X50 magnifier switch magnifies the horizontal
display by 10 or 50 times around the center graticule line. This
may extend the maximum sweep speed to 1 ns/div. The X50 mag-
nification is not calibrated on the 4, 2 and 1 ns/div ranges.
You can use the Alternate Magnifier feature (ALT MAGN) to dis-
play the magnified and unmagnified sweep alternately on the crt
screen in the Non-Store mode. You can reposition the unmagnified
sweep vertically with the Trace Seperation control (TR SEP) in the
ALT MAGN mode.
2. Horizontal Store Display Mode
In Store mode, the 2212 provides a calibrated sweep speed range
from 50 s to 20 µs per division. The maximum sampling rate is
20 megasamples per second with a stored record length per wave-
form of 4096 points (4096) for single-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, may be
stored in the reference memory as a reference waveform, giving a
total Bk 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.
With the 2212 in X-Y mode, digital storage mode is also one of the
features.
