is
obtained from the plug-in units that are installed in the plug-in compartments. The characters of the readout display are written by the CRT beam on a time-shared basis with the signal waveforms.

Time markers applied to the EXT INTENSITY INPUT provide a direct time reference on the display. With uncalibrated horizontal sweep or X-Y operation, the time markers provide a means of reading time directly from the display. However, if the markers are not time-related to the displayed waveform, a single-sweep display should be used (for internal sweep only) to provide a stable display.

Intensity (Z-Axis) modulation can be used to relate a third item of electrical phenomena to the vertical (Y-Axis) and the horizontal (X-Axis) coordinates without affecting the waveshape of the displayed signal. The Z-Axis modu-
lating signal, applied to the EXT INTENSITY INPUT, changes the intensity of the displayed waveform to provide this type of display. The voltage amplitude required for visible trace modulation depends on the setting of the
INTENSITY control. About +5volts will turn on the display to a normal brightness level from an off level, and about -5 volts will turn the display off from a normal
brightness level. "Gray scale" intensity modulation can be

feedback networks to provide good linearity at fast sweep
rates. The Zener diode-fast switching series diode, CR242-VR240 and CR272-VR270 (across each of the
feedback networks in the output amplifier), turn on when the sweep passes the right edge of the CRT. This action stops the collectors of the output transistors and shunts out the feedback networks, thus current limiting the output amplifier.

Delay Line
Delay line DL100 provides approximately 140 ns of delay for the vertical signal. This allows the time-base circuits time to initiate a sweep before the vertical signal

The delay line has a characteristic input impedance of
about 75 ohms, or about 150 ohms from side-to-side.

Internal adjustments, R572, Prep Level, and R590, Op
Level, set the quiescent operating levels for the CRT in the storage mode. R585, WRITING SPEED control, allows a small adjustment to be made in the operate, level, which increases the CRT's ability to store a fast waveform. During
the erase cycle the storage mesh is made a high positive for
50 ms, returned to its operate level for 10 ms, then made slightly positive level for 440 ms. The two positive-going erase signals (see Fig. 2-1) are supplied to the storage mesh by the collectors of 0515 (50 ms) and 0555 (440 ms).

Erase Generator
Pushing the ERASE pushbutton creates a negative pulse at the base of Q510. R665-R500-C500 remover network for the ERASE pushbutton with R500 used to dampen any ringing. 0510 and 0515 form monostable multivibrator; C514 and R507 are the timing components. Coupling capacitor C528 couples the 50 ms multivibrator to the input of the I0 ms monostable multivibrator consisting of 0530-0535. The timing components for 0530-0535 are C534 and R530. The output from the 10 ms multivibrator input of the 440 ms monostable multivibrator by C538. 0550-0555, along with timing components C554 and R545 form the 440 ms monostable multivibrator. The

monostable multivibrators are cascaded to provide sequential pulse train. Diodes CR560, CR562 and CR564 make up an OR gate to supply a composite erase signal to
the flood-gun anode circuit.

0625 and 0640 form a monostable multivibrator that triggered by the output of the 10 ms pulse generator consisting of programmable unijunction transistor 0610. The timing components for the monostable multivibrator are C625, R622 and R620 PERSIST control. The 10 ms pulse generator timing components are C610, R608 and
R609. 0635 acts as a switch for R620 PERSIST control.

ADJUSTMENTS
Adjustment is generally required after a repair has been made, or after long time intervals in which normal aging of components may affect instrument accuracy. For initial inspection to verify instrument operation, the basic opera­tion procedure in section
1
should be used (the instrument is checked with its covers on, using a minimum of peripheral equipment).
Before complete adjustment, thoroughly clean and inspect this instrument as outlined in the service section of the 5403 manual. Also, the system manual contains information for general maintenance of this instrument, including preventive maintenance, component identifica­tion and replacement, etc.
Services
Available
Tektronix, Inc., provides complete instrument repair and adjustment at local Field Service Centers and at the Factory Service Center. Contact your local Tektronix Field Office or representative for further information.

a. Install a vertical dual-trace plug-in in the left plug-in compartment and a time-base plug-in in the right plug-in compartment.
b.
Check that the correct nominal line-selector block has been installed on the line-selector pins and that the regulating range selected includes the input line voltage,
see
Installation section for complete instructions.
c. Connect the 5403-D41 to the line voltage source and
pull the POWER switch out to turn the instrument on.
1.
Check Trigger Amplifier
Connect a properly terminated
60 MHz1 signal to channel vertical plug-in. Set the time-base secldiv switch to time-base plug-in triggering controls to trigger on plug-in compartment signal.
Adjust the output amplitude of the sine-wave generator for exactly graticule division of signal. Check that a stable display can be obtained.
2.
Check Beam Finder
Using the signal established in step 1
press the BEAM FINDER pushbutton. Check that the display intensity in­creases and that the signal cannot be positioned out of the viewing area as long as the BEAM FINDER pushbutton is depressed.
Disconnect the signal.
3. Check Calibrator Connect the signal from the front-
panel CALIBRATOR loop to channel on the vertical plug-in. Set the time-base secldiv switch to channel I voltsldiv to time-base triggering controls for a stable display. Check for a display four major graticule divisions high.
Disconnect the signal.
4.
Check 2-Axis Amplifier
Connect
signal to the EXT INTENSITY INPUT connector. Also, use the sine-wave signal to externally trigger the time-base plug-
in. Set the time-base plug-in controls for an external, automatic, triggered sweep. Check that bright spots occur at
regular intervals along the trace. be necessary to reduce the trace bright-
ness to observe the Z-axis modulation.
Disconnect the signal.
5. Check Chop and Alternate Set the time-base
50
m and push the chop pushbutton in.
Set the vertical plug-in for dual-trace
operation. Check for two spots, one above the other, going across the CRT.
Install a second dual-trace plug-in in the center plug-in compartment and set its controls for dual-trace operation. Set the time-base chop pushbutton to its out position. Check for two sweeps for the left plug-in (one for each channel), then two sweeps for the center plug-in,
alternately.

'A 5A48 Dual Trace Amplifier and a plug-in units were used for this check. If other plug-in units are used the trigger amplifier bandpass will depend on the vertical plug-in

MANUAL CHANGE INFORMATION
At Tektronix, we continually strive to keep up with latest electronic developments by adding circuit and component improvements to our instruments as soon as they are developed and tested.
Sometimes, due to printing and shipping requirements, we can't get these changes immediately into printed manuals. Hence, your manual may contain new change information on following pages.
A single change may affect several sections. Since the change information sheets are carried in the manual until all changes are permanently entered, some duplication may occur. If no such change pages appear following this page, your manual is correct as printed.
SERVICE NOTE
Because of the universal parts procurement problem, some electrical parts in your instrument may be different from those described in the Replaceable Electrical Parts List. The parts used will in no way alter or compromise the performance or reliability of this instrument. They are installed when necessary to ensure prompt delivery to the customer. Order replacement parts from the Replaceable Electrical Parts List.
CALIBRATION TEST EQUIPMENT REPLACEMENT

This chart compares TM

product performance to that of older Tektronix equipment. Only those
characteristics where significant specification differences occur, are listed. In some cases the new instrument
may not be a total functional replacement. Additional support instrumentation may be needed or a change in
calibration procedure may be necessary.
