OPERATING
INSTRUCTIONS
The D41 Single eam storage display module operates
with a Tektronix 5400-series power supply/amplifier
module to form an oscilloscope mainframe. This section
gives a familiarization procedure, and general operating
information.
The Installation section of the 5403 instruction manual
should be referred to for initial preparation. It contains
information for installation of plug-ins, correct operating
voltage and temperature, and general oscilloscope usage.
A brief description of the function of the front and rear
panel controls and connectors is given on the controls and
connectors foldout page. More detailed information is given
under General Operating Information.
BASIC OPERATION
Setup Information
The following steps demonstrate the use of the controls
and connectors of the D41 .
Amplifier Plug-In
1. Make sure the oscilloscope system is complete. The
D41 must be properly connected to the power supply/
amplifier module. A 5A-series amplifier plug-in should be in
one of the vertical (left or center) plug-in compartments
and a 5 -series time-base plug-in should be in the horizontal
(right) compartment.

2. Set the POWER switch to off (pushed in) and
connect the D41 to a power source that meets the voltage
and frequency requirements of this instrument. See Installa 
tion section in this manual, or in the 5403 manual.
3. Turn the INTENSITY and READOUT INTENS
controls counterclockwise and pull the POWER switch out
to turn the instrument on. Set the front-panel controls as

4. Advance the INTENSITY control until the trace is at
the desired viewing level. The trace should appear near the
graticule center.
5. Connect a 1X probe or test lead from the CALI 
RATOR loop to the amplifier plug-in input connector.
6. Turn the Main Trig Level control clockwise until a
stable display is obtained. Adjust the vertical and horizontal
1-1

Operating Instructions — D41
Position controls so that the display is centered vertically
and starts at the left edge of the graticule.
7. Adjust the FOCUS control for a sharp, well-defined
display over the entire trace length.
8. Disconnect the input signal and position the trace
vertically so that it coincides with the center horizontal line
of the graticule.
9. If the trace is not parallel with the center horizontal
line, see Trace Alignment Adjustment in this section.
10. Rotate the GRAT ILLUM control throughout its
range and notice that the graticule lines are illuminated as
the control is turned clockwise. Set control so graticule
lines are illuminated as desired.
C libr tion Check
11. Move the trace two divisions below graticule center
and reconnect the calibrator signal to the amplifier plug-in
input connector.
12. The display should be four divisions in amplitude
with six complete cycles (five complete cycles for 50-hertz
line frequency) shown horizontally. An incorrect display
indicates that the oscilloscope mainframe or plug-ins need
to be recalibrated.
Re dout
13. Turn the READOUT INTENS control clockwise
until an alpha-numeric display is visible within the top or
bottom division of the CRT (reset the FOCUS adjustment
if necessary for best definition of the readout). Change the
Volts/Div switch of the amplifier plug-in that is selected for
display. Notice that the readout portion of the display
changes as the deflection factor is changed. Likewise,
change the Sec/Div switch of the time-base unit that is
selected for display. Notice that the readout display for the
time-base unit changes also as the sweep rate is changed.
14. Set the time-base unit for magnified operation.
Notice that the readout display changes to indicate the
correct magnified sweep rate. If a readout-coded 10X probe
is available for use with the vertical unit, install it on the
input connector of the vertical plug-in. Notice that the
deflection factor indicated by the readout is increased by
10 times when the probe is added. Return the time-base
unit to normal sweep operation and disconnect the probe.
15. Notice that the readout for a particular plug-in
occupies a specific location on the display area. If either of
the vertical plug-in units is a dual-trace unit, notice that the
readout for channel 2 appears within the lower division of
the CRT below the readout for channel 1.
Be m Finder
16. Move the display off-screen with the vertical posi 
tion control.
17. Push the EAM FINDER button and observe that
the display compresses into the screen area. Reposition the
display to screen center and release the EAM FINDER
button.
Extern l Intensity Input
18. Connect a 5 volt, 1 kHz sine-wave or square-wave
signal to the EXT INTENSITY INPUT connector on rear
panel of D41. Also, use the signal to externally trigger the
time-base plug-in.
19. Slowly rotate the INTENSITY control counter 
clockwise until the trace appears to be a series of dimmed
and brightened segments. The brightened segments corre 
spond with the tops of the square waves.
Stor ge Oper tion (V ri ble Persistence)
20. Disconnect the 5 volt, 1 kHz sine-wave or square 
wave signal from the EXT INTENSITY INPUT connector.
Reset the time-base plug-in triggering controls for an
internally-triggered display from the vertical plug-in.
21. After making sure the calibrator signal is still
connected to the amplifier plug-in input connector, set the
controls on the time-base plug-in for single-sweep opera 
tion. Press the STORE button and note that the CRT will
momentarily be flooded positive (becoming quite bright).
22. Press the Reset button on the time-base plug-in. One
sweep will be generated, and a display should be visible, but
will fade out within a few seconds. Increase the VARI 
A LE PERSIST control setting if a display of longer
retention is required. Increase the WRITING SPEED setting
to increase the background level for viewing lightly written
information. If there is no display visible, increase the
INTENSITY control setting and press the Reset button.
23. Press the ERASE button; the CRT should turn
positive and erase. Press the Reset button on the time-base
plug-in to obtain another stored display on the CRT. Press
1-2
