SECTION I
GENERAL INFORMATION
1-1. DESCRIPTION.

1-5. OPTIONS.

1-2. The rfj) Model 140A (Figure 1-1) is a general
purpose plug-in oscilloscope. The deflection amplifiers are contained within the plug-in units, which
operate directly into the cathode-ray tube. Thus
the characteristics of the oscilloscope are dependent
upon the plug-ins used. Presently available plug-ins
make possible high-sensitivity, wide bandwidth, and
single, dual, or four-trace measurements, in combination with normal, single, or delayed sweeps.
Double-size plug-ins also are available for special
applications such as time domain reflectometry.

1-6. The Model 140A normally is supplied with a
type P31 aluminized phosphor CRT. The following
options, however, are available:

1-3. The Model 140A provides power for the plugins, as well as line-frequency square-wave calibrating voltages of 10 volts and 1 volt peak-to-peak,
which are available on the front panel of the Model
140A.
The primary power switch and all CRT
controls are on the Model 140A front panel, and the
terminals and switch for Z-axis modulation are on
the rear panel.
1-4. The Model 140A uses an internal graticule
CRT which eliminates parallax error in observing
the display. The CRT is equipped with a nonglare
safety face plate.

a. Option 02.
b. Option 07.
c. Option 11.

P 2 phosphor (general purpose)
P7 phosphor (long persistence)
P 11 phosphor (fast writing rate)

1-7. ASSOCIATED EQUIPMENT.
1-8. Some of the plug-ins available for the Model
140A Oscilloscope are listed in Table 1-2. The
Model 140A normally is used with an amplifier
plug-in in the lower compartment and a sweep plugin in the upper compartment. The plug-in in the
lower compartment produces vertical deflection,
and the plug-in in the upper compartment produces
horizontal deflection.
All rfj) Model 1400-series
plug-ins can be used with the Model 140A Oscilloscope.
Plug-in model numbers are grouped according to
function:

pulling the transistor from its socket. All other
low voltage power supply transistors are located on
the low-voltage circuit board.
5-21. Nominal voltages at significant points iil the
supply are given in the low-voltage power supply
schematic. Plug-ins must be installed when checking
these voltages.
Correct voltages for points not
marked for voltage are generally obvious by being
connected (directly or indirectly) to a supply output.
Transistor base voltage in most cases should not
measurably differ from emitter voltages when measured with respect to ground. Voltage drops across
breakdown diodes are indicated on the schematic.
5-22. EXCESSIVE RIPPLE. The cause of excessive
120-cycle ripple on any of the supplies can be isolated
to input filter or regulator circuits by comparing
ripple voltages at the rectifier outP'-lts with the values
given on the schematic. If ripple at these points is
excessive, check capacitors C121, C122, C141, C161,
or C181. If ripple is high and is 60 cps, one of the
rectifiers is probably open. If normal, the cause
is most likely low gain in the amplifier transistors.
In the -100 volt supply, slave amplifiers Q161
and/or Q163 could be open, and the only indication
might be poor regulation and ripple at low line voltage.
5-4

5-23. FUSES. If the -100, +100, or +250 volt supply
should be accidentally shorted to ground, the fuse
for that particular supply will blow. This cuts off
current in the supply and protects the transistors.
5-24. The -12.6 volt supply is not fused, but employs
a surge protector, Q184, for protection against brief
shortings of the output to ground. The supply should
immediately function normally upon removal of the
short.
5-25. LOSS OF REGULATION. If loss of regulation
occurs in a supply, refer to Table 5-4. The procedure outlined in this table may not always pin down
the exact trouble, especially if a component other
than a transistor or breakdown diode has failed, but
it will usually indicate the general location of the
failure.
In using the procedure, follow the steps
listed under a particular symptom in the given order.
In some cases, more than one fault may exist.

5-26. HIGH-VOLTAGE SUPPLY.
5-27. If one high-voltage supply output is zero but
other outputs are normal, look for the unlit filament
of a bad rectifier (V302 thru V305). Normal DC
voltages are given on the high voltage schematic.

5- 28. If there is no high voltage output and none of
the filaments are lit, observe the waveform at the
collector of Q302 (blue wire). If an approximately
30 kc 20-volt peak-to-peak sine wave appears for
short intervals, the trouble is probably a defective
component in the rectifier filter/divider networks.
If no waveform appears, use Table 5-5.
5-29. If the high voltage output is incorrect and
cannot be adjusted to the correct value, use Table 5-6.

'.

5-30. If the -2350 volt supply seems to be operating
properly, the +5 kv post-accelerator potential may
be checked by removing the left side instrument
cover and measuring the 5-kv voltage at the board
termination of the thick red lead.
5-31. REPAIR AND REPLACEMENT.

5-32. AIR FILTER.
5-33. Inspect the air filter at the rear of the instrument and clean it before it becomes clogged enough
to restrict the flow of cooling air. To clean, remove
the filter from the instrument and wash it thoroughly
in warm water and detergent. Dry thoroughly and
coat with a filter adhesive such as Filter Coat No.3
from Research Products Inc. . This adhesive is
available from heating supply stores or from your
Hewlett-Packard Engineering Representative.

c. Remove CRT bezel.
d. Loosen clamp at socket of CRT.
e. Remove socket of CRT by carefully prying
loose.
f. Slide CRT forward out of instrument, keeping
one hand on front face of CRT.
5-36. To install CRT, reverse the above procedure.
Correct connection of leads at neck of CRT is shown
on the inside of bottom cover and in Figure 5-1.
Note
If a different CRT is installed, it will be

necessary to:
1) Check trace alignment
with procedure given in Paragraph 3-7;
2) Reset Geometry adjustment as described
in Paragraph 5-16; 3) Check plug-in calibration.

5-37. FAN MOTOR REMOVAL.
a. Disconnect the white-gray and white-green-gray
wires from fan terminals at bottom of instrument.
b. Remove all four transistor heat sinks from the
fan assembly, and push out of the way.

5-34. REMOVAL OF CATHODE-RAY TUBE.
5-35. It is recommended that a face mask or goggles
and gloves be used when it is necessary to handle
the CRT. To remove:
a. Disconnect post-accelerator lead. This can be
done by lifting the edge of the rubber cap, and using
a screwdriver to compress the spring contact until
it comes free.
b. Disconnect leads at neck of CRT, taking care
not to bend the pins.

c. Remove the four nuts on rear panel which
secure the fan assembly to instrument frame.
d. Lift out fan assembly.
e. Remove fan motor brackets.
5-38. To install fan, reverse the above procedure.
When tightening the mounting nuts on the rear panel,
use long-nose pliers or similar tool to prevent
rubber shock mounts from twisting.

Indication

Conclusion

2. Remove the edge-on connector which goes to
the emitter of Q301 (yellow wire). Connect
this lead through a 2K resistor to -12.6 volts
(any white-violet wire).

Rectifier (V302- V305)
filaments light.

Proceed to step 3.

Filaments don't light.

Proceed to step 4.

3. Replace edge-on connector, and change V301.

Filaments light.

Q301 was bad.

Filaments don't light.

Check biasing circuitry of
V301. Then check Q301 and
associated circuitry.

Filaments light.

Put capacitors back one at
a time until the bad one
causes filaments to go out.

Filaments don't light.

Trouble probably with
transformer T301.

4. Check T301 and rectifier load circuit for
opens or shorts. Then lift one lead of C313,
C314, C315, C316, C317, C321, and turn
instrument on again.

5-39. REMOVAL OF HIGH-VOLTAGE ASSEMBLY.
a. Disconnect the six leads identified in Figure 5-3.
b. Disconnect post-accelerator lead as described
in Paragraph 5-35a.
c. Remove the four screws identified in Figure 5- 3.
d. Tip assembly away from left side of instrument
and lift out from top.
5-40. To install high-voltage assembly, reverse the
above procedure.
5-41. SERVICING ETCHED CIRCUIT BOARDS.
5-42. Etched circuit boards used in the Model 140A
have components on one side of the board with a
plated conductive layer of metal through component
holes. r§j) Service Note M- 20D also contains useful
information on etched circuit repair. The important steps and considerations are:
a. Use a low heat (37to47.5watts, less than 800°F
idling temperature), slightly bent chisel tip (1/16 to
1/8 inch diameter) soldering iron, and a small diameter, high tin content solder. If a rosin solder is
used, clean the area thoroughly after soldering.
b. Components may be removed by placing the
soldering iron on the component lead on either side
of the board, and pulling up on the lead. If heat is
applied to the component side of the board, greater
care is required to avoid damage to the component
(especially true for diodes). If heat damage may
occur, grip the lead with a pair of pliers to provide
a heat sink between the soldering iron and component.

Figure 5-3. Removal of HighDeck Assembly

c. If a component is obviously damaged or faulty,
clip the leads close to the component and then unsolder the leads from the board.

from the board. A conductor may be cemented back
in place with a quick-drying acetate base cement (use
sparingly) having good insulating properties. Another
method for repair is to solder a section of good conducting wire along the damaged area.

d. Large components such as potentiometers and
tube sockets may be removed by rotating the soldering
iron from lead to lead and apply steady pressure to
lift the part free (the alternative is to clip the leads
of a damaged part).

f. Clear the solder from the circuit board hole
before inserting a new component lead. Heat the
solder in the hole, remove the iron, and quickly
insert a pointed non-metallic object, such as a
toothpick.

e. Since the conductor part of the etched circuit
board is a metal plated surface, covered with solder,
use care to avoid overheating and lifting the conductor

g. Shape the new component leads and clip to
proper length. Insert the leads in the holes and apply
heat and solder, preferably on the conductor side.
