2213 Operators
Using the Delay Time Controls
1.
Select
INTENS
HORIZONTAL MODE.
2.
Rotate the MULTIPLIER control; observe that the
start of the intensified zone moves along the display.
3. Select DLY’D HORIZONTAL MODE and observe
that the intensified zone, previously viewed with
INTENS
selected, is now displayed on the crt screen.
4.
Observe that the display moves continuously across
the screen as the MULTIPLIER control is rotated.
5. Set the
SEC/DIV
switch to 5 ps and observe that the
magnification of the display is approximately 100 times
greater.
6.
Select NO DLY HORIZONTAL MODE and return
the
SEC/DIV
switch to 0.5 ms.
Using the Trigger Section
1. Rotate the TRIGGER LEVEL control between its
maximum clockwise and counterclockwise positions. The
display will remain triggered throughout the rotation of the
control.
2. Return the TRIGGER LEVEL control to the
midrange position.
3. Set the TRIGGER SLOPE switch to
7_
(minus).
Observe that the display starts on the negative-going slope
of the applied signal.
4.
Return the TRIGGER SLOPE switch to
f
(plus).
Observe that the display starts on the positive-going slope
of the applied signal.
5. Set the INT switch to CH 1, select CH 2 VERTICAL
MODE, and set the Channel
1
AC-GND-DC switch to GND.
Observe that the display free-runs. Return the Channel
1
AC-GND-DC switch to AC.
6. Set the
INT
switch to CH 2, select CH 1 VERTICAL
MODE, and set the Channel 2 AC-GND-DC switch to GND.
Observe that the display free-runs. Return the Channel 2
AC-GND-DC switch to AC and set the INT switch to
VERT MODE.
7. Set the TRIGGER MODE switch to NORM.
8. Rotate the TRIGGER LEVEL control between its
maximum
clockwise and counterclockwise positions.
Observe that the TRIG
’D indicator illuminates only when
the display is correctly triggered.
9.
Set
the TRIGGER MODE switch to AUTO and set
the TRIGGER SOURCE switch to EXT.
10. Remove the calibration signal from the CH 2 input
connector and connect it to the EXT INPUT connector.
11.
Set
the CH 1
VOLTS/DIV
switch to 0.5
(IX)
and
adjust the output of the calibration generator to provide
a 4-division display. Adjust the TRIGGER LEVEL control
for a stable display and note the range over which a stable
display can be obtained
(for comparison in step 13).
12. Set the TRIGGER SOURCE switch to
EXT÷10
13. Observe that adjustment of the TRIGGER LEVEL
control provides a triggered display over a narrower range
than in preceding step 11, indicating trigger-signal
attenuation.
14.
Remove the calibration signal from the EXT INPUT
connector and reconnect it to the CH 2 input connector.
Set the TRIGGER SOURCE switch to INT and adjust the
TRIGGER LEVEL control
for a stable display.
Using the X-Y Mode
1.
Set both the CH 1 and CH 2
VOLTS/DIV
switches
to 1 (IX) and adjust the generator output to provide a
5-division
display.
2. Select X-Y mode by switching the
SEC/DIV
switch
to its fully counterclockwise position.
3. Adjust the AUTO INTENSITY control for desired
display brightness.
Observe that two dots are displayed
diagonally. This display can then be positioned horizontally
with the Horizontal POSITION control and vertically with
the Channel 2 POSITION control. Note that the dots are
separated by 5 horizontal divisions and 5 vertical divisions.
4. Set both the CH 1 and CH 2
VOLTS/DlV
switches
to 2 (1X). Note that the dots are now separated by 2.5
horizontal divisions and 2.5 vertical divisions.
5. Return the
SEC/DIV
switch to 0.5 ms and adjust the
AUTO INTENSITY control for desired display brightness.
