OPERATING INFORMATION
The Tektronix 5440 Oscilloscope is a solid-state instrument designed for general-purpose applications, This
instrument has three plug-in compartments that accept 5000-series plug-in units to form a complete measu rement system,
To effectively use this instrument, the operation and capabilities of the instrument must be known. This section describes
front-panel control functions, giving first-time and general operating information. Information on operating voltage,
instrument conversion, reckmounting, operating temperature, and plug-in installation is also included.
FIRST TIME OPERATION
Steps 1 through 19 of the foliowing procedure provide
an operational check to verify satisfactory operation of the
osciiloscope and associated piug-ins. Refer to Fig. 1-1 for
fronit-panel control and connector locations.
1. For the following procedure, a 5A-series amplifier
plug-in should be in one of the vertical (ieft or center)
plug-in compartments and a 5B-series time-base plug-in
should be in the horizontal (right) compartment.

the desired viewing level. The trace should appear near the
graticule center.
5. Connecta 1X probe, or a testiead from the amplifier
plug-in input connector to the CALIBRATOR loop.
6. Turn the Main Trig Level control clockwise until a
stable display is obtained. Adjust the vertical and horizon-
tal 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 thatit coincides with the center horizontal line
of the graticuie.
9. If the trace is not paralie! with the center horizontal
line, see Trace Alignment Adiustment 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 the control so
graticule lines are illuminated as desired.
Calibration Check
11. Move the trace two divisions beiow graticuie center
and reconnect the calibrator signal {io 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 horizontaily. An incorrect display
indicates that the oscilipsocpe mainframe or plug-ins
need to be recalibrated.
Readout
13. Turn the READOUT INTENS control clockwise
until an alphanumeric display is visible within the top or
bottom division of the cri (reset the FOCUS adjustment if
necessary for best definition of the readout). Change the
Volts/Div switch of the ampiitier plug-in thatis 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.
Operating information--5440
14. Set the time-base unit for magnified operation.
Notice that the readout display changes io indicate the
correct magnified sweep rate. If a readout-coded 10X
probe is availabie for use with the vertical unit, install iton
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 disconnecithe probe. .
15. Notice that the readout from a particular plug-in
occupies a specific location on the display area. Hf 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 cri below the readout for Channel 1.
Beam Finder
16. Move the display off-screen with the vertical
position contro.
17. Push the BEAM FINDER button and observe that
the display compresses into the screen area. Reposition
the display to screen center and release the BEAM
FINDER button.
External Intensity input
18. Connecta 5 volt, 1 kHz sine-wave Or square-wave
signal to the EXT INTENSITY INPUT connector on the
rear panel, Also, use the signa! to externaliy 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 segmenis
correspond with the tops of the calibrator squarewaves.
GENERAL OPERATING INFORMATION
Display Focus
if a weii-defined display cannot be obtained with the
FOCUS control, even at low intensity settings. adjustment
of the internal astigmatism control may be required,
To check for proper setting of the Astig control, slowly
turn the FOCUS control through the optimum setting with
a signal displayed on the ¢rt screen. H the Astig control is
correctly set, the vertical and horizontal portions of the
trace will come into sharpest focus at the same position of
the FOCUS control.

Operating Information—5440
Beam Finder
The BEAM FINDER switch provides a means of
iocating a display that overscans the viewing area either
vertically or horizontally. When the BEAM FINDER switch
is pressed, the display is compressed within the graticule
area and the display intensity is increased. To locate and
reposition an overscanned display, use the following
procedure:
1. Press the BEAM FINDER switch, hold it in, then
increase the vertical and horizontal deflection factors until
the display is within the graticule area.
2. Adjust the vertical and horizontal position controls
io center the display about the vertical and horizontal
centeriines.
3. Release the BEAM EINDER switch; the display
shouid remain within the viewing area.
Readout (Works Only With 5400-Series Plug-in
Units)
The readout system of the power supply/amplifier and
display modules aliows alphanumeric display of informa-
tion on the crt, along with the analog waveform displays.
The information displayed by the readout system is
obtained from the plug-in units that are installed in the
plug-in compariments. The characters of the readout
display are written by the crt beam on à time-shared basis
with the signal waveiorms.
The Readout System operates in a free-running mode
to interrupt the waveform display to present characters.
The waveform display is interrupted for only about 20
microseconds for each character that is displayed.
The readout information from each piug-in is called a
word. Up to six {eight with Option 3) words of readout
information can be displayed. The location at which each
readout word is presented is fixed and is directly related to
the plug-in unit and channel from which it originated. Fig.
1-2 shows the area of the graticule where the readout from
each plug-in unit channel is displayed {external readout
programming is available only with Option 3). Notice that
the readout from Channel 1 of each plug-in unit is
displayed within the top division of the graticule and the
readout from Channel 2 is displayed directly below within
the bottom division of the graticuie. Only the readout from
plug-in channels that are selected by display switches, or
by the mode switches of dual-channel plug-ins, appear in
the readout display.
1-4
The READOUT INTENS control determines the inten-
sity of only the readout portion of the display independent
of the other traces. The readout system is inoperative in
the fully counterciockwise OFF position. This may be
desirable when the top and bottom divisions of the
graticule are to be used tor waveform display, or when the
trace interruptions necessary to display characters do not
allow a satisfactory waveform display to be obtained.
Option 3, Exiernally Programmed Seventh and
Eighth Readout Words
This option adds a 25-pin connector to the rear-panei of
the 5440 through which two ten-character readout words
can be displayed on the crt, see Fig. 1-2.
Display Switching Logic
The electronic switching for time-shared displays is
produced at the plug-in interface within the mainframe;
however, the switching logic is selected in the plug-in
units. The system allows any combination of plug-ins and
Display switch settings. Refer to the individual piug-in
manuals for specific capabilities and operating
procedures.

REV MAR 1987
NOTE
At sweep rates faster than approximately 1 us, the
5810, 5812, and 5B13 Time Base plug-in trigger
circuit will not respond fast enough, when used in a
5440, to allow the leading edge of the display to be
observed.
Differences in wiring between the 5100-series and
5400-series oscilioscope plug-in interfaces will not
allow the use of the composite trigger mode of the
SEO, 5812, and 5813 Time Base plug-ins when
used in the 5440. If the time base units are put in this
mode, they will trigger off the left vertical plug-in
only.
Vertical Plug-in Compartments. When a vertical plug-in
is in the active mode (Display button pushed in), a logic
level is applied to the switching circuit in the mainframe
and a display from this plug-in will occur. When two plug-
ins are both active in the vertical compartments, a multi-
trace display will occur {Alternate or Chopped). When no
plug-in is in the active mode, the signal from the left
compartment will be displayed. A time-base unit operated
in one of the vertical compartments has a permanent
internal connection to apply a logic level to the switching
circuit; thus, a vertical trace produced by this unit will
always be displayed,
Horizontal Plug-In Compartment. Alternate or
Chopped display switching is selected ona time-base unit
operated in the horizontal compartment. When the
Display switch is out (Alt), a negative impulse is supplied
at the end of the sweep to allow alternate switching
between plug-ins and plug-in channels. When the Display
switch is pushed in {Chop), a chopped display will appear
if a multi-trace display is required by the plug-ins in the
vertical compartments. A vertical plug-in unit operated in
the horizontal compartment has a permanent internal
connection to provide a chopped display # it is required.
Switching Sequence. Four display time slots are
provided on a time-sharing basis. When two vertical plug-
ins are active. each receives two time siots, so the
switching sequence is: left, left, center, center, etc. The
two time slots aliotied to each plug-in are divided between
amplifier channels in a dual-trace unit; if two dual-trace
piug-ins are active, then the switching sequence is: left
Channel 1, left Channel! 2, center Channel 1, center
Channel 2, etc. 11 only one vertical plug-in is active, it
receives all four time slots. The switching sequence is the
same for both the Allernate and Chopped display modes.
REV MAR 1987
Operating Information—5440
Vertical Display Mode
Display On. To display a signal, the Display button of
the appiicable vertical plug-in unit must be pushed in to
activate the unit. if two plug-ins are installed in the vertical
compartments and only the signal from one of the units is
wanted, set the Display switch of the unwanted unit to ОН
(button out). H neither plug-in is activated, the signal from
the left unitis dispiayed. Both plug-ins can be activated for
multi-trace displays.
Alternate Mode. The alternate position ofthe time-base
unit Display switch produces a display that alternates
between activated plug-ins and amplifier channels with
each sweep of the crt. The switching sequence is describ-
ed under Display Switching Logic in this section.
Although the Alternate mode can be used at all sweep
rates, the Chop mode provides a more satisfactory display
at sweep rates from about one millisecond/division 10 five
seconds/division. At these slower sweep rates, alternate-
mode switching becomes difficult to view.
Chopped Mode. The Chop position of the time-
base unit Display switch produces a display that is
electronicaliy switched between channels at a 100-
Kilohertz rate. The switching sequence is discussed
earlier. In general, the Chop mode provides the best
display at sweep rates slower than about one
millisecond/division or whenever dual-trace, single-
shot phenomena are to be displayed. At faster sweep
rales, the chopped switching becomes apparent an
may interfere with the display. |
Dual-Sweep Displays. When a dual-sweep time-base
unit is operated in the horizontal compartment, the
alternate and chopped time-shared switching for either
the A or B sweep is identical to that for a single time-base
unit. However, if both the A and B sweeps are operating,
the 5440 operates in the independent pairs mode. Under
this condition, the left vertical unit is always displayed at
the sweep rate of the A time base and the right vertical unit
is displayed at the sweep rate of the B time-base (non-
delayed sweep only). This results in two displays that have
compietely independent vertical deflection and chopped
or alternate sweep switching.
X-Y Operation
In some applications, it is desirable to display one
signal versus another (X-Y) rather than against an internal
sweep. The flexibility of the plug-in units available for use
with the 5440 provides a means for applying a signal to the
horizontal deflection system for this type of display. Some
of the 5B-series time-base units can be operated as
amplifiers, in addition to their norma! use as time-base
generators.
1-5
Operating Information--5440
Raster Display
A raster-type display can be used to effectively increase
the apparent sweep length, For this type of display, the
trace is defiected both vertically and horizontally by
sawtooth signals, and is accomplished by installing a 58-
series time-base unit in the left vertical compartment, as
well as one in the horizontal compartment. Normally, the
unit in the vertical compartment shouid be set to a siower
sweep rate than the one in the horizontal compartment;
the number of horizontal traces in the raster depends upon
the ratio between the two sweep rates. Information canbe
displayed on the raster using the Ext Intensity Input to
provide intensity modulation of the display. This type of
raster display can be used to provide a television-type
display.
Intensity Modulation
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
modulating 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 +5 volts 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
noymal brightness level. "Gray scale” intensity moduta-
tion can be obtained by applying signals between these
levels. Maximum safe input voltage is +50 volts, Usable
frequency range of the Z-Axis circuit is de to two
megahertz.
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
marxers 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.
Calibrator
The internal calibrator of the 5440 provides a con-
venient signal source for checking basic vertical gain and
sweep ming. The calibrator signal is also very useful for
adjusting probe compensation, as described in the probe
instruction manual. The output square-wave voltage is 400
millivolts, within 1%, and the sguare-wave current is 4
milliamperes, within 1%. The frequency of the square-
wave signal is twice the power-line frequency. The signal
is obtained by clipping the probe to the loop.
1-6
Display Photography
A permanent record of the crt display can be obtained —
with an oscilloscope camera system. The crt bezel of the
5440 provides integral mounting for a Tektronix os-
cilioscope camera, The instruction manuals for the
Tektronix oscilloscope cameras include complete instruc-
tions for obtaining waveform photographs.
OPERATING VOLTAGE
ca UTION
PO S
This instrument is designed for operation from a
power source with its neutral at or near earth
(ground) potential, and with a separate safety-earth
conductor. It is not intended for operation from two
phases of a multi-phase system, or across the legs of
a single-phase, three-wire system.
INSTRUMENT CONVERSION
The 5440 Power Supply/Amplifier module and the display
module can be fastened together stacked or side by side;
this permits operation as a bench oscilloscope, orin a stan-
dard 19-inch rack. The two modules can quickly be convert-
ed from a bench model to a rackmount model, or vice versa.
Field conversion kits, including the necessary parts, and
instructions are available and can be installed at a later time.
See your Tektronix Catalog or contact your Tektronix field
office. |
NOTE
Before attempiing to operate the instrument, make
sure the module wiring interconnections are correct.
RACKMOUNTING
The rackmount version of the 5400-series oscilloscope is
designed for operation in a standard 19-inch wide rack that
has Universal, IA, RETMA, or Western Electric hole spac-
ing. When properly mounted, this instrument will meet all
electrical and environmental specifications given in Section
2.
REY MAR 1687
Mounting Method
This instrument will fit most 18-inch wide racks whose
front and rear holes conform to Universal hole spacing,
some drilling may be required on racks having EIA, RETMA,
or Western Electric hole spacing. The slide-out tracks easily
mount to the cabinet rack front and rear vertical mounting
rails if the inside distance between the front and rear rails is
within 10-8/16 inches to 24-3/8 inches. If the inside distance
exceeds 24-3/8 inches, some means of support is required
for the rear ends of the slide-out tracks. (For example, make
extensions for the rear mounting brackets.)
Rack Dimensions
Height. At least 5-1/4 inches of vertical space is required
to Mount this instrument in a rack. if other instruments are
operated in the rack, an additional 1/4 inch is required, both
above and below the oscilloscope, to allow space for proper
circulation of cooling air.
Width, A standard 18-inch wide rack may be used. The
dimension of opening between the front rails must be at
least 17-5/8 inches for a cabinet in which the front lip of the
stationary section is mounted behind an untapped front rail
as shown in Fig. 1-4A. If the front rails are tapped, and the
stationary section is mounted in front of the front rail as
shown in Fig. 1-4B, the dimension between the front rails
should be at least 17-3/4 inches. These dimensions allow
room on each side of the instrument for the slide-out tracks
10 operate so the instrument can move freely in and out of
the rack.
Depth. For proper circulation of cooling air, allow at least
two inches clearance behind the rear of the instrument and
any enclosure on the rack. if it is sometimes necessary or
desirable to operate the oscilloscope in the fully extended
position, use cables that are long enough to reach from the
signal source to the instrument.
| WARNING |
During rackmount installation, interchanging the left
and right slide-out track assemblies defeats the exten-
sion stop (safety latch) feature of the tracks, Equip-
ment could, when extended, come out of the slides
and fall from the rack, possibly causing personal injury
and equipment damage.
REY MAR 1987
Operating information -— 5440
When mounting the supplied slide-out tracks, inspect
both assemblies to find the LH (left hand) and RH
{right hand) designations to determine correct place-
ment. Install the LH assembly to your left side as you
face the front of the rack and install the RH assembly
to your right side. Refer to the rackmounting instruc-
tions in this manual for complete information.
Lie,
Installing The Slide-Out Tracks
The slide-out tracks for the instrument consist of two
assemblies, one for the left side of the instrument and one
for the right side. Each assembly consists of three sections.
A stationary section attaches to the front and rear rails of
the rack, the chassis section attaches to the instrument
(and is installed at the factory), and the intermediate section
fits between the other two sections to allow the instrument
to fully extend out of the rack.
The small hardware components included with the slide-
out track assemblies are used to mount the tracks to most
standard 18-inch rack rails having this compatibility.
NOTE
1. Front and rear rail holes must be large enough to
allow inserting a 10-32 screw through the rail mount-
ing hole if the rails are untapped (see Fig. 1-4A).
2. Or, front and rear rail holes must be tapped to ac-
cept a 10-32 screw if Fig. 1-4B mounting method is
used. Note in Fig. 1-4B right illustration that a No. 10
washer (not supplied) may be added to provide in-
creased bearing surface for the slide-out track station.
ary section front flange.
Because of the above compatibility, there will be some
small parts left over. The stationary and intermediate sec-
tions jor both sides of the rack are shipped as a matched
set and should not be separated. The matched sets of both
sides including hardware are marked 351-0195-00 on the
package. To identify the assemblies, note that the automat-
ic latch and intermediate section stop is located near the top
of the matched set.
Mounting Procedure. Use the following procedure to
mount both sides. See Fig. 1-4 for installation details.
1-7
Operating information—5440
1. To mount the instrument directiy above or below
another instrument in a cabinet rack, select the ap-
propriate holes in the front rack rails for the stationary
sections, using Fig. 1-5 as a guide.
2. Mount the stationary slide-out track sections to the
front rack rails using either of these methods:
{a} Hthe front flanges of the stationary sections are
to be mounted behind the front raiis (rails are counter-
sunk or not tapped}. mount the stationary sections as
shown in Fig. 1-4A right illustration.
{b} HH the front flanges of the stationary sections are
to be mounted in front of the front rails (rails are tapped
for 10-32 screws), mount the stationary sections as
shown in Fig. 1-4B right illustration. To provide in-
creased bearing surface for the screw head to securely
fasten the front flange to the rail, a flat washer (not
supplied) may be added under the screw head.
However, if this mounting method is used, the front
panel will not fit flush against the front rail because of
the stationary section and washer thickness. if a flush
fit is preferred, method 2 (a) should be used.

3. Mount the stationary slide-out sections to the rear
rack rails using either of these methods.
(a) If the rear rack rail holes are not tapped to accept
10-32 machine screws, mount the left stationary sec-
tion with hardware provided as shown in the left or
center illustration of Fig. 1-4A. Note that the rear
mounting bracket can be installed either way so the
siide-Qut tracks will fit a deep or shallow cabinet rack.
Use Fig. 1-4A as a guide for mounting the right
stationary section. Make sure that the stationary sec-
tions are horizontally aligned so they are level and
parallel with each other.
(b) 1f the rear rack rail holes are tapped to accept
10-32 machine screws, mount the left stationary sec-
tion with hardware provided as shown in the left or
center illustration of Fig. 1-4B. Note that the rear
mounting bracket can be installed either way so the
slide-out tracks will {it a deep or shailow ¢abinet rack.
Use Fig. 1-48 as a guide for mounting the right
stationary section. Make sure the stationary sections
are horizontally aligned so they are level and parallel
with each other.
Installation And Adjustment
To insert the instrument into the rack, proceed as
follows:
1. Pull the slide-out track intermediate sections out to
the fully extended position.
2. Insert the instrument chassis sections into the
intermediate sections.
3. Press the stop latches on the chassis sections and
push the instrument toward the rack until the tatches snap
into their holes.
4. Again press the stop latches and push the instru-
ment into the rack.
To adjust the slide-out tracks for smooth stiding action,
loosen the screws used to join the stationary sections 10
the rails of the rack. Center the instrument, allowing the
slide-out tracks to seek the proper width, then tighten the
screws.
To secure the instrument front-panel to the rack, the
rack must either have universal hole spacing, or a hole
must be dritled and tapped fora 10-32 screw, see Fig. 1-5.
Using the hardware (not furnished) indicated in Fig. 1-5,
secure the R5440 to the front rails of the rack.

Slide-Out Track Maintenance
The slide-out tracks require no lubrication. The special |
dark gray finish on the sliding parts is a permanent
lubrication,
OPERATING TEMPERATURE
The 5440 can be operated where the ambient air
temperature is between 0% C and +50%C, The instrument
can be stored inambient temperature between —40°C and
+70°C, After storage at a temperature beyond the
Operating limits, allow the chassis temperature to come
within the operating limits before power is applied.
A thermal cutout in the display module provides
thermal protection and disconnects the power to the
instrument if the internal temperature exceeds a safe
operating level. This device will automatically re-apply
power when the temperature returns to a safe level.
PLUG-IN UNITS
The 5440 is designed to accept up to three Tektronix
5000-series plug-in units. (Only the p:ug-in units without
an N suffix will provide display readout} This plug-in
feature allows a variety of display combinations and also
allows selection of bandwidth, sensitivity, display mode, и
etc., to meet the measurement requirements. in addition, it
allows the oscilioscope system 10 be expanded to meet
future measurement requirements. The overall
capabilities of the resultant system are in large part
determined by the characteristics of the plug-ins selected.
installation
To install a plug-in unit into one of the plug-in
compariments, align the slots in the top and bottom ofthe
piug-in with the associated guides in the plug-in compart-
ment. Push the plug-in unit firmiy into the plug-in
compartment until it locks into place. To remove a plug-in,
pull the release latch on the plug-in unit to disengage it
and pull the unit out of the plug-in compartment. Plug-in
units can be removed or instalied without turning off the
instrument power. It is not necessary that all of the plug-in
compartments be filled to operate the instrument, the only
plug-ins needed are those required for the measurement
to be made.
When the display unit is adjusted in accordance with
the adjustment procedure given in the display unit instruc-
tion manual, the vertical and horizontal gain are standar-
dized. This allows adjusted plug-in units to be changed
from one plug-in compartment to another without read-
justment. However, the basic adjustment of the individual
piug-in units shouid be checked when they are installed in
this system to verify their measurement accuracy. See the
service information section of the plug-in unit manual for
verification procedure.

Selection
The plug-in versatility of the 5400-series oscilloscope
altows a variety of display modes with many different piug-
ins. The following information is provided here to aid in
plug-in selection.
To produce a single-trace display, install a single-
channel vertical unit (or dual-channel unit set for single-
channel operation) in either of the vertical (left or center)
compartiments and a time-base unit in the horizontal
(right) compartment. Fordual-trace displays, either install
a dual-channel vertical unit in one of the vertical com-
partments or install a single-channet vertical unit in each
vertical compartment. A combination of a single-channel
and a dual-channel vertical unit allows a three-trace
display. likewise, a combination of two dual-channel
vertical units allows a four-trace display.
To obtain a vertical sweep with the input signal
displayed horizontally, insert the time-base unit into one
of the vertical compartments and the amplifier unit in the
horizontal compartment. If a vertical sweep is used, there
Is no retrace blanking and the time-base unit triggering
must be accomplished externally.
For X-Y displays, either a 5A-series amplifier unit or a
5B-series time-base unit having an amplifier channel can
“be instatied in the horizontal compartment to acceptthe X
signal. The Y signal is connected to a 5A-series amplifier
unit installed in a vertical compartment.
Special purpose plug-in units may have specific restric-
tions regarding the compartments in which they can be
instalied. This information will be given in the instruction
manuais for these plug-ins.
BASIC OSCILLOSCOPE APPLICATIONS
The 5400-series oscilloscope and its associated plug-in
units provide a very flexible measurement system. The
capabilities of the overall system depend mainly upon the
plug-ins that are chosen. The following information
describes the techniques for making basic measurements.
These applications are not described in detail, since each
application must be adapted to the requirements of the
individual measurement. Specific applications for the
individual plug-in units are described in the manuals for
these units, Contact your focal Tektronix Field Office or
representative for additional assistance,

Peak-to-Peak Voltage Measurements--AC
To make peak-to-peak voltage measurements, use the
following procedure:
1. Set the input coupling on the vertical plug-in unit to
Gnd and connect the signal to the input connector.
2. Set the input coupling to ac and set the Volts/Div
switch to display about 5 or 6 vertical divisions of the
waveform, Check that the variable Volts/Div control (red
knob} is in the Cal position.
3. Adjust the time-base triggering controls for a stable
display and set the Sec/Div switch to display several
cycles of the waveform.
4. Turn the vertical Position control so that the lower
portion of the waveform coincides with one of the
graticule lines below the center horizontal line, and the top
of the waveform is in the viewing area. Move the display
with the horizontal Position control so that one of the
upper peaks is aligned with the center vertical reference
line (see Fig. 1-6).
5. Measure the vertical deflection from peak to peak
(divisions).
NOTE
This technique may also be used to make
measurements between two points on the waveform,
rather than peak to peak,
5. Muitipty the distance (in divisions) measured instep
5 by the Volts/Div switch setting. Also include the
atienuation factor of the probe, if applicable.
EXAMPLE: Assume a peak-to-peak vertical deflection
of 4.6 divisions and a Voits/Div switch settings of 5 Y,

Instantaneous Voltage Measurementi—DC
To measure the dc level at a given point on a waveform,
use the following procedure:
1. Set the input coupling of the vertical plug-in unit to
Gnd and position the trace to the bottom fine of the
graticule (or other selected reference line). If the voltage
to be measured is negative with respect to ground,
position the trace to the top line of the graticule. Do not
move the vertical Position control after this reference has
been established.
NOTE
To measure a voltage leve! with respec! to a voltage
other than ground, make the following changes to
step 1: Set the input coupling switch to dc and apply
the reference voltage to the input connector, then
position the trace to the reference fine.
1-12
2. Connect the signal to the input connector. Set the —
input coupling to dc (the ground reference can be
checkedatany time by setting the input coupling to Gnd).
3. Set the Voits/Div switch to dispiay about 5 or 6
vertical divisions of the waveform. Check that the variable
Volis/Div control (red knob) is in the Cal position. Adjust
the time-base triggering controls for a stable display.
4. Measure the distance in divisions between the
reference line and the point on the waveform at which the
de leve! is to be measured. For example, in Fig. 1-7 the
measurement is made between the reference line and
point À.
5. Establish the polarity. The voltage is positive if the
signal is applied to the + input connectar and the
waveform is above the reference line.
6. Multipiy the distance measured in step 4 by the
Volts/Div switch setting. Include the attenuation factor of
the prope, if applicable (see the note following the Peak-
to-Peak Voltage Measurement example).

Comparison Measurements
In some applications, it may be necessary to establish a
set of deflection factors other than those indicated by the
Volts/Div or Sec/Div switches. This is useful for com-
paring signais to a reference voltage amplitude or period.
To establish a new set of deflection factors based upon a
specific reference amplitude or period, proceed as
follows:
Vertical Deflection Factor
1. Apply a reference signal of known amplitude to the
vertical input connector. Using the Voits/Div switch and
variable Volts/Div control, adjust the display for an exact
number of divisions. Do not move the variable Voits/Div
controi after obtaining the desired defiection.
2. Divide the amplitude of the reference signal {voits)
by the product of the deflection in divisions {established in
step 1) and the Volts/Div switch setting. This is the
Deflection Conversion Factor.
Deflection reference signa! amplitude (voits)
Conversion =
Factor deflection X Volts/Div
(divisions) setting
3. Todetermine the peak-to-peak amplitude of a signal
compared to a reference, disconnect the reference and
apply the signal to the input connector,
4. Set the Volts/Div switch to a setting that provides
sufficient defiection to make the measurement. Do not
readiust the variable Volis/Div control.
5. To establish a Modified Deflection Factor at any
setting of the Voits/Div switch, multiply the Volts/Div
switch setting by the Deflection Conversion Factor es-
tablished in step 2.

Operating Information—5440
EXAMPLE: Assume a reference signal amplitude of 30
volts, a Voits/Div switch setting of 5 V and a deflection of
four divisions. Substituting these values in the Deflection
Conversion Factor formula (step 2):
30 V
ce == 1.5
(4) (5 Y)
Then, with a Volts/Div switch setting of 2 V, the
Modified Deflection Factor {step 5) is:
(2 V) (1.5) = 3 volts/division
To determine the peak-to-peak amplitude of an applied
signal that produces a vertical deflection of five divisions
with the above conditions, use the Signal Amplitude
formula (step 6):
{3 V} (5) = 15 volts
Sweep Rate
1. Apply a reference signal of known freguency to the
vertical input connector. Using the Sec/Div switch and
variable Sec/Div control, adjust the display so that one
cycle of the signal covers an exact number of horizontai
divisions. Do not change the variabie Sec/Div controi after
obtaining the desired deflection. -
2. Divide the period of the reference signal (seconds)
by the product of the horizontal deflection in divisions
{established in step 1) and the setting of the Sec/Div
switch, This is the Deflection Conversion Factor.

3. To determine the period of an unknown signal,
disconnect the reference and apply the unknown signal.
4. Set the Sec/Div switch to a setting that provides
sufficient horizontal deflection to make an accurate
measurement. Do not readjust the variable Sec/Div con-
trot.
5. To establish a Modified Deflection Factor at any
setting of the Sec/Div switch, muitipiy the Sec/Div switch
setting by the Deflection Conversion Factor established in
step 2.

6. Measure the horizontal defiection in divisions and
determine the period by the following formula:
Modified horizontal
Period == Defiection X defiection
Factor {divisions}
EXAMPLE: Assume a reference signal frequency of 455
nertz (period 2.2 milliseconds), a Sec/Div switch setting of
2 ms, and a horizontal deflection of eight divisions.
Substituting these values in the Deflection Conversion
Factor formula (step 2}:
2.2 ms
(8) (02ms) 1*7
Then, with a Sec/Div switch setting of 50 us, the
Modified Defiection Factor (step 5) is:
{50 us) (1.375) = 68.75 microseconas/division
To determine the time period of an applied signal which
compietes one cycie in seven horizontal divisions, use the
Period formula (step 6):
(68.75 us) (7) = 481 microseconds
This product can be converted to frequency by taking
the reciprocal of the period (see application of Deter-
mining Frequency).
Time Period Measurement
Te measure the time (period) between two points ana
waveform, use the foliowing procedure:
1. Connect the signal to the vertical input connector,
select either ac or de input coupling, and set the Voits/Div
switch to display about four divisions of the waveform.
2. Set the time-base triggering controls to obtain a
Stable display, Set the Sec/Div switch to the fastest sweep
rate that will permit displaying one cycle of the waveform
in ess than eight divisions (some non-linearity may occur
in tne first and (ast graticute divisions of display}. Refer to
Fig. 1-8,
3. Adjust the vertical Position control to move the
points between which the time measurement is made to
the center horizontal line. Adjust the horizontal Position
control to center the time-measurement points within the
center eight divisions of the graticule.
1-14
4. Measure the horizontal distance between the time
measurement points. Be sure the variable Sec/Div control
is in the Cal position,
5. Multiply the distance measured in step 4 by the
setting of the Sec/Div switch,
EXAMPLE: Assume that the horizontal distance
between the time-measurement points is five divisions and
the Sec/Div switch is set to .1 ms. Using the formula:
horizontal Sec/Div
Period = distance X switch = (5) (0.1 ms) = 0.5 ms
(divisions) setting
The period is 0.5 millisecond.
Determining Frequency
The time measurement technique can also be used to
determine the frequency of a signal. The frequency of a
periodically recurrent signal is the reciprocal of the time
duration (period) of one cycie. Use the foliowing
procedure:
1. Measure the period of one cycte of the waveform as
described in the previous application.
2. Take the reciprocal of the period to determine the
frequency.
EXAMPLE: The frequency of the signal shown in Fig. 1-
8. which has a period of 0.5 millisecond is:

Risetime Measurement
Risetime measurements employ basically the same
techniques as the time-period measurements. The main
difference is the points between which the measurement is
made. The following procedure gives the basic method of
measuring risetime between the 10% and 90% points of the
waveform.
1. Connect the signal to the input connector.
2. Set the Volts/Div switch and variable Volts/Div
control to produce a display exactly five divisions in
amplitude.
3. Center the display about the center horizontal line
with the vertical Position control.
4. Set the time-base triggering controls to obtain a
stable display. Set the Sec/Div switch to the fastest sweep
rate that will display less than eight divisions between the
10% and 90% points on the waveform (see Fig. 1-8).
5. Adjust the horizontal Position control to move the
10% point of the waveform to the second vertical line of the
graticule.
6. Measure the horizontal distance between the 10%
and 80% points. Be sure the variable Sec/Div control is in
the Cal position.
7. Multiply the distance measured in step 6 by the
setting of the Sec/Div switch.

The risetime is 4 microseconds.
Time Difference Measurements
When used in conjuction with a calibrated time-base
plug-in unit, the multi-trace feature of the 5400-series
oscilloscope permits measurement of time difference
between two or more separate events. To measure time
difference, use the following procedure:
1. Set the input coupling switches of the amplifier
channels to either ac or dc.
2. Setthe Display switch on the time-base unit to either
Chop or Alt. In general, Chop is more suitable for low-
frequency signals. More information on determining the
mode is given under Vertical Display Mode in this section.
3, Set the vertical plug-intriggering switches to trigger
the display on Channel 1 (or left plug-in} only.
4. Connect the reference signal to the Channel 1 input
connector and the comparison signal to the Channel 2 {or
center plug-in} input connector. The reference signal
should preceded the comparison signal in time. Use
coaxial cables ог probes which have similar time-delay
characteristics to connect the signal to the input connec-
tors.
5. If the signals are of opposite polarity, invert the
Channel 2 {or center plug-in) display. {Signals may be of
opposite polarity due to 180% phase difference; if so, take
this into account in the final calculation.)
6. Set the Volts/Div switches to produce about four
divisions of display waveform.
7. Set the time-base triggering controls for a stable
display. Set the Sec/Div switch for a sweep rate which
shows three or more divisions between the measurement
points, if possible.
8. Adjust the vertical Position controls to bring the
measurement points to the center horizontal reference
line.

Operating Information-—5440
9. Adjust the horizontal Position controi so the
Channei 1 (or left plug-in) waveform (reference) crosses
the center horizontal line at a vertical graticule line.
10. Measure the horizontal distance between the wo
measurement points (see Fig. 1-10).
11, Muitiply the measured distance by the setting of
the Sec/Div switch.
EXAMPLE: Assume that the Sec/Div switch is set to
50 us and the horizontal distance between measurement
points is four divisions. Using the formula:

Multi-trace Phase Difference Measurement
Phase comparison between two or more signals of the
same frequency can be made using a dual-trace piug-in or
two single-trace plug-ins. This method of phase difference
measurement can be used up to the frequency limit of the
vertical system. To make the comparison, use the foliow-
ing procedure:
1. Set the input coupling switches of the amplifier
channels to either ac or dc.
2. Setthe Display switch on the time-Ddase unit to either

frequency signals and the Alt position is more suitable for
high-frequency signals. More information on determining
the mode is given under Vertical Display Mode in this
section,

3. Set the vertical plug-in triggering switches to trigger
the display on Channel 1 {or left piug-in) only.
4. Connect the reference signal to the Channel 1 input
connector and comparison signal to the Channel 2 (or
center piug-in) input connector. The reference signal
should precede the comparison signalin time. Use coaxial
cables or probes which have similar time-delay
characteristics to connect the signals tothe input connec-
tors.
5. li the signals are of opposite polarity invert the
Channel 2 (or center plug-in} display. (Signals may be of
opposite polarity due to 180° phase difference; if 50, take
this into account in the final calculation.)
6. Set the Voits/Div switches and the variable Voits/Div
controls so the displays are equal and about five divisions
in amplitude.
7. Set the time-base triggering controls to obtain a
stable display. Set the Sec/Div switch to a sweep rate
which displays about one ¢cycie of the waveform,
8. Move the waveforms to the center of the graticule
with the vertical Position controls.
9. Turn the variable Sec/Div contro! until one cycie of
the reference signal (Channel 1, or left plug-in) occupies
exactly eight divisions between the second and tenth
vertical lines of the graticule {see Fig. 1-11). Each division
of the graticuie represents 45° of the cycle {360° + 8
divisions =45° /division}, The sweep rate can be stated in
terms of degrees as 45°/division.

10. Measure the horizontal difference between cor-
responding points on the waveforms.
11. Multiply the measured distance (in divisions) by
45° /dwvision {sweep rate) to obtain the exact amount of
phase difference.
EXAMPLE: Assume a horizontal difference of 0.6

1-11. Use the formula:
Phase horizontal sweep rate
Difference = difference X (degrees/ — (0.6) (45°) = 27°

The phase difference is 27°.
High Resolution Phase Measurement
More accurate dual-trace phase measurements can be
made by increasing the sweep rate {without changing the
“variable Sec/Div control setting). One of the easiest ways
to increase the sweep rate is with the Swp Mag {10X)
— button on the time-base unit. The magnified sweep rate is
automatically indicated by the crt readout and knob-skirt
scale-factor readout.
REV MAR 1987
Operating information—5440
EXAMPLE: If the sweep rate were increased 10 times
with the magnifier, the magnifier sweep rate shouid be
45°/division + 10 = 4.5% /division. Fig. 1-12 shows the
same signals as used in Fig. 1-11, but with the Swp Mag
button pushed in. With a horizontal difference of six
divisions the phase difference is:
