SECTION I
GENERAL INFORMATION
l-l. INSTRUMENT DESCRIPTION.
1-2. The m@$ Model 214APulseGenerator (Figure l-l)
is a versatile instrument providing variable repeti­tion rate, variable width, variable amplitude, posi­tive or negative, pulses with a rise and fall time of
less than 15 nanoseconds. The complete specifica­tions are given in Table l-l. Pulse power of up to
200 watts is available when using a 50-ohmload. The
Model 214A output impedance matches an external
system of 50 ohms on all ranges of 50 volts amplitude
and below, thus minimizing reflections. The maxi-
mum pulse amplitude is 100 volts (with a source
impedance of 1500 ohms) and the amplitude may be
set as low as 80 millivolts using the vernier and the
lowest range. For pulse amplitudes of 10 volts and
less, the duty cycle may be set as high as 50% (see
Table l-l for duty cycle limits at other amplitudes), providing a square wave output.
l-3. Pulses may be obtained from the Model 214A at a rate of dc to 1 MC using an external trigger source
or from 10 cps to 1 MC with an internal generator.
For external triggers, positive or negative signals
of 0.5 volt peak may be used and trigger slope and level may be selected to determine the triggering point on the waveform. A single pulse may be obtained from an internal circuit each time a manual button is pushed. Gating of pulses is done easily by applying an external signal and an output occurs only when the gating signal reaches a positive 8 volt level. Three
modes of pulse operation allow: (1) setting of the output pulse to occur from 0 to 10 ms before (advance) the trigger output, (2) setting of the output pulse to occur from 0 to 10 ms after (delay) the trigger output, or (3) a double pulse output with variable spacing between the two pulses.
l-4. The Hewlett-Packard modular instrument en­closure system provides advantages in maintenance and operation. Easy removal of instrument covers allows access to all chassis and circuit components. As a bench type instrument the modular design pro­vides mechanical stability even when several instru­ments are stacked together. The bench type instru­ment is readily converted for use in standard width

l-5. INSTRUMENT APPLICATIONS.
l-6. With its variable pulse characteristics the
Model 214A is useful as a general purpose laboratory
or production line test instrument.
The high peak current output available, 2 amps, is useful for testing current driven devices such as magnetic memory cores, high power modulators, and power amplifiers.
Fast rise and fall time combined with highpower out-
put pulses facilitate checking switching time of high
power semiconductors. The positiveor negative pulse output, with identical characteristics, provides an
easy technique for checking either npn or pnp type
transistors. By gating the Model 214A output, a burst of pulses may be obtained for making computer
logic measurements. The double pulse feature may also be used for pulse resolution tests of amplifiers and memory cores.
l-7. EQUIPMENT AND ACCESSORIES
AVAILABLE.
l-8. A complete line of electronic test equipment
is available from the Hewlett-Packard Company for
use in making test measurements with, or maintain­ing, the Model 214A. Also available are cables,
connectors, adapters and other accessory items for
use in various test or measurement applications.
For information on specific items, consult the &?
Catalog or your @ Field Engineer.
1-9. DIFFERENCES BETWEEN INSTRUMENTS.
l-10. The Hewlett-Packard Company uses a two-
section, eight-digit serial number to identify instru­ments (e.g. ~-00000). The serial number is located on a plate attached to the instrument rear panel. The first three digits are a serial prefix number, also appearing on the first page of this manual, and the last five digits identify a specific instrument. If the serial prefix number of the instrument is higher than that on the first page, change sheets included with the manual will define differences between other instru-
ments and the Model 214A described herein. If the
change sheets are missing, your @J Field Engineer
can supply the information. Refer to Appendix I at the back of this manual for changes required to adapt this manual to an instrument with a lower serial prefix.

PREPARATION FOR USE
2-1.
INIT
IAL INSPECTION.
2-2.
Upon receipt of the Model 214A, verify that
the contents are intact and complete as ordered.
Inspect the instrument for any physical damage such
as a scratched panel surface, broken knob or con­nector, possible reshipment, material if reusable (see Paragraph 2-15), until a satisfactory operational check (Paragraph 5-3) is completed. If damage is found, file a claim with the freight carrier and refer to the warranty page in
this manual. Section V outlines the recommended
adjustment and troubleshooting procedures needed
for normal maintenance or recalibration.
2-3. AC POWER CONSIDERATIONS.
2-4. POWER SOURCE REQUIREMENTS.
2-5. The Model 214A may be operated from an ac
source of 115 or 230 volts (&lO%), at 50 to 60 cps. With the instrument power cord disconnected, move the slide switch (located on the rear panel) until the desired voltage numbers (115 or 230) are visible. A narrow-blade screwdriver may be used to operate the switch. Fuse Fl (holder on rear panel) should be
3.2 amperes, slow-blow for 115~ operation or 1.6
amperes, slow-blow for 230~ operation.
2-6. THREE-CONDUCTOR POWER CABLE.
2-7. To protect operating personnel, the National
Electrical Manufacturers’ Association (NEMA) re-
commends that the instrument and cabinet be grounded. The Model 214A is supplied with a detachable three-
conductor power cable which, when plugged into an appropriate receptacle, grounds the instrument to the power line ground. The round pin on the power cable is the ground connection. To retain the pro­tection feature when operating the instrument from a two-contact outlet, use a three-conductor to two­conductor adapter and connect the adapter wire to a
suitable ground.
2-B. VENTILATION REQUIREMENTS. 2-9.
GENERAL. The cooling fan and air filter are located on the rear panel of the Model 214A. Leave adequate clearance (at least 2 to 3 inches) behind and at both sides of the instrument for free movement of air. The path of air flow is through the filter and intake fan then out of the perforated side covers. It is important to keep the air intake area free of dust
and small particles which could clog the filter. Section V provides maintenance information for fan
and filter. In a rack installation be sure that re­circulation of warm air within the rack cabinet does
not produce an ambient temperature high enough to affect instrument operation.

Paragraphs 2-1 to 2-1’7
Section II
2-10. COATING FILTER. Before placing the instru­ment in use, the air filter should be coated with a filter adhesive preparation. A recommended pre-
paration is No. 3 Filter Coat, made by Research
Products Company, and available in sprayer cans at heating-supply stores. This may also be obtained by contacting your @ Field Engineer (see maps at back
of this manual) or by ordering directly from @
Customer Service. Hewlett-Packard stock number is 3150-0002.
2-11. RACK/BENCH CONVERSION.
2-12. The Model 214A is shipped as a bench-type instrument (even when ordered as a rack type) with
plastic feet and tilt stand in place. The @ modular
instrument enclosure system allows easy conversion
to either bench or rack
mode.
Refer to the appropri-
ate following procedure for conversion.
2-13. CONVERSION TO RACK MODEL.
a. Detach the tilt stand and all the plastic feet. Tilt stand removes by pressing away from the front feet. Remove feet by depressing metal release
button and sliding feet free.
b. Using a thin-blade tool, loosen and remove the
plastic trim strip (with adhesive back) from eachside of the instrument (directly behind front handles).
Removal of strip exposes threaded nuts pressed in
the side casting.
c. Attach the rack-mounting flanges, with the screws provided, in the space where the trim strip was adhered. Each flange extends slightly below the front panel when attached correctly.
d. If the instrument is to be placed in a rack above
or below another @ modular instrument, attach the filler strip between the front panels. Insert Model
214A in the rack and secure flanges to rack.
2-14. CONVERSION TO BENCH.
a. Remove instrument from rack, detach rack­mounting flanges and filler strip, if used between
front panels.
b. Attach trim strip (in slots where rack flanges were located), plastic feet, and tilt stand. A fifth plastic foot at center-front of the instrument provides
extra stability when the Model 214A is stacked atop
another @ modular bench-type instrument.
2-15. REPACKAGING FOR SHIPMENT. 2-16. PACKAGING SUGGESTIONS.
2-17. To package an instrument for shipment, some types of original packing materials may be reused,
or your @ Field Engineer will provide assistance in
obtaining suitable packaging. The types of original
2-l
Section II Paragraphs 2-18 to 2-19
Model 214A
packing materials which may be reused are: (1) foam enclosure pads, (2) cardboard layers separated by foam supports, and (3) laminated cardboard cut to desired packing shape. Original packing materials which are a cardboard “accordion-like” filler are not recommended for shipment since the useful cushioning qualities are usually gone after one use. If packing materials listed above are not available, first protect the instrument surfaces with heavy paper or sheets of cardboard flat against the instru-
ment. Then place instrument in a durable carton,
pad all sides with approximately 4 inches of new packaging material designed specifically for package cushioning, mark carton clearly for proper handling, and insure adequately before shipping.
2-18. RETURNING FOR SERVICE OR REPAIR.

OPERATING INSTRUCTIONS
3-1. GENERAL.
3-2. The Model 214A is self-protected and no com­bination of front panel control settings or connections to external circuits can damage the instrument, pro­viding the overload relay circuitry is operating pro­perly. duty cycle specified in Table l-l are exceeded. The limits and combinations of settings which result in an overload indication are described in Paragraph 3-4. Other specific operating considerations are given in Paragraphs 3-7 and 3-9. Figure 3-3 illustrates and
explains the function of all the front panel fixtures. The ac power connector, fuse, and line voltage switch are on the rear panel. Proper fusesize is: 3.2 amps slow-blow for 115~ and 1.6 amps slow-blow for 230~ operation. Setting line switch and other ac power information is given in Paragraph 2-3.
3-3. OPERATING CONSIDERATIONS. 3-4. DUTY CYCLE LIMITATION.
3-5. panel control settings. Duty cycle is defined as the ratio of duration of pulse (i.e. pulse width) to the total duration of one complete cycle. Figure 3-1 shows the relationship which determines the duty cycle. The time for one cycle is defined as the period, and the period is related to repetition rate by:
Thus the product of pulse width and frequency times 100 determines the percent duty cycle. For example if INT. REP. RATE is set to l-10, VERNIER set to give a rate of 6 kc (or if the external trigger rate is 6 kc), and PULSE WIDTH and VERNIER are set to give a pulse 70 psec wide, the percent duty cycle is:
The same limits on duty cycle apply for external

3-6. If maximum duty cycle is exceeded for any pulse amplitude, the front panel light, OVERLOAD, will flash on and off and an internal relay will be heard
as a clicking sound. No damage will occur to the
instrument when this overload circuit is operating properly. When an overload is indicated it may be
stopped by reducing either the frequency or the PULSE WIDTH setting. Usually this may be done easiest by turning the Width VERNIER counterclockwise, or by
reducing the Width range setting. In DOUBLE PULSE operation the duty cycle limit is one half that for
PULSE ADVANCE or PULSE DELAY. The expression for duty cycle using DOUBLE PULSE is given in
Figure 3-2.

For proper operation without affecting pulse shape, there are minimum spacing limits between the two pulses, and these limits depend on the PULSE WIDTH setting. between pulses is 1 psec. For other PULSE WIDTH settings, the minimum spacing is 25% of the upper limit of range selected. For example, if PULSE WIDTH is set to 100-lK, the minimum spacing between pulses is 25% of 1K microseconds, or 250 microseconds. characteristics as set by the Model 214A controls in DOUBLE PULSE mode. Note from Figure 3-2 that the setting of PULSE POSITION and PULSE WIDTH controls the actual spacing between pulses. The spacing between pulses is then the PULSE POSITION setting minus the PULSE WIDTH setting.
3-11. GATING OF PULSES.
3-12. By applying a positive signal voltage to the GATE INPUT (+) connector and sliding the switch to GATED, pulses will occur at the output only when the gating signal is at +8 volts or greater. The maximum gating signal amplitude is +40 volts. To ensure that output pulses occur when the gate signal just reaches
+8v, a fast rise time input should be used. If a gating
sine wave signal is used, a larger amplitude (but less than 40 volts peak) will generally provide better re­sults. and repetition rate must be locked together. Figure 3-4 illustrates the result of gating the pulse output.

4-2. The complete circuit operation is shown in Figure 4-1.
lowing general sequence: a trigger pulse from the
rate circuit (VlOZ), functioning either as a Schmitt
trigger or an astable multivibrator, is applied to blocking oscillator V103, which triggers both the Position Multivibrator (V201A, VZOZA, V104B) and blocking oscillator V203 for the trigger output pulse. The position Multivibrator triggers Position Blocking Oscillator V201B which in turn triggers both start
and stop pulse circuits.
are used to switch a bistable multivibrator-power amplifier combination (V304, V305, Q301) which forms the output pulse. The details of each block
are contained in the schematics, and the following
circuit description explains the operation of each
circuit, both as to basic type and to the part it plays in the sequence of forming the output pulse.
4-3. INPUT AND RATE GENERATOR.
4-4. EXTERNAL TRIGGER OPERATION.
4-5. With TRIGGER MODE set to EXT. position, a
signal of at least 0.5 volts peak will cause Differential Amplifier VlOl to amplify the difference between the levels at the control grids, pins 2 and 7. TRIGGER SLOPE switch SlOl routes the trigger input to one grid of VlOl and also transfers the external trigger level circuit of R105 to the other grid. Resistor R105
sets the grid bias which must be overcome by the trigger input at the other grid to obtain an output at the plate, pin 6 of V101. The output from VlOl is
coupled through S103A, through a low-impedance network (DSlOl, R116, and C107), and S103B to R125
and the grid of V102.
The output pulse is formed by the fol-
The start and stop pulses

MANUAL switch S102 is energized, the side of capaci­tor Cl06 toward the switch charges toward +150 volts through R120. This positive-going, slow rising ex-
ponential voltage is coupled to the grid (pin 2) of V102
and the left half of the tube conducts. The right half of V102 now cuts off and a positive pulse to +15OV is
the output coupled to the grid of V103.
4-9. INTERNAL TRIGGER OPERATION.
4-10. With TRIGGER MODE set toINT. position, V102
functions as an astable multivibrator. The free-
running rate of this circuit is controlled by range
capacitors, Cl13 through C117, couplingbetweenplate
(pin 1) and grid (pin 7), and by VERNIER, R137. Breakdown diode CR101 sets the bias at the grid of the left half of V102. This circuit has no stable state and is always changing between two states: (1) left­half cutoff, right-half conducting or (2) left-half con­ducting, right-half cutoff. The rate at which this changing of states occurs is primarily a function of the capacitors between plate and grid since this de­termines the exponential rise and decay time of the grid (pin 7). When the grid (pin 7) voltage rises exponentially enough to cause the right half to conduct, the output at pin 6 is about +125 volts. Then as the voltage at pin 7 decays exponentially, the right half cuts off and the output at pin 6 is at the supply voltage, +15Ov. A regenerative action occurs as the right half
of V102 just starts to conduct and the left half starts
to cutoff: the increase in voltage at the plate (pin 1) is coupled through the range capacitor to speed turn on of the right half. Symmetry Adjust, R133, changes the grid bias of pin 7 to nearly equal the bias at pin 2 making the two halves of the waveform equalin width,
Section IV
4-6. In external trigger operation, V102 functions as a cathode-coupled binary, or Schmitt Trigger,
circuit. The plate to grid coupling network is from pin 1 through S103B and the parallel RC combination, R129-C110, to the grid, pin 7. The left half of V102 is normally off and the right half conducting so the output at pin 6 is at a positive level (about 125 volts), less than the +150 supply. As the signal at pin 2 becomes positive enough (upper hysteresis limit), the left half of V102 conducts and regenerative action
cuts the right half off. When the input at pin 2 de­creases enough (lower hysteresis limit), the left half of V102 is cut off and the circuit returns to the original state. The output at pin 6 then is a positive pulse each time the signal at pin 2 causes the left half to conduct, and the rate at which this occurs is exactly that of the external trigger signal (1 MC limit on input fre­quency). The output pulse from pin 6 is coupled through Cl22 to pin 2 of Blocking Oscillator V103.
02056-2
4-11. TRIGGER BLOCKING OSCILLATOR.
4-12.
Tube V103 and transformer TlOl function as an amplifier-blocking oscillator, when the output of V102 is not being gated by the circuit of V104A (see Paragraph 4- 13). Normal operation of the blocking oscillator is as a monostable circuit being triggered by an amplified signal. The left half of V103 amplifies the positive pulse at its grid and the resulting plate
pulse is coupled through transformer TlOl, reversed
in phase, to the grid of the right half. This puts the right half of V103 in conduction and a regenerative action drives the plate (pin 6) voltage down abruptly and the grid voltage (pin 7) abruptly positive. Next the action reverses and as the plate voltage becomes more positive, the grid goes negative and regeneration turns the tube off agian. The output is taken from the cathode (pin 8) and the pulse drives other circuits de-
pending on which pulse mode (advance, delay, or
double) is used (see Paragraph 4-15).

Section IV Paragraphs 4-13 to 4-30
Model 214A
4-13. GATE INPUT CIRCUIT.
4-14. When switch S105 is in the NORM. position, Gate Cathode Follower V104A is conducting enough so CR103 is biased off, and the pulse at pin 2 of V103 is
unaffected in operation.
However, when S105 is moved
to GATED, V104A is cut off, biasing the cathode of CR103 more negative than its anode and CR103 con­ducts, changing V103 input impedance so the rate pulse does not develop enough signal to trigger the blocking oscillator. By applying a positive signal of at least 8 volts (but less than 40) V104A will again conduct, cutting off CR103 and the pulse at V103 triggers the
blocking oscillator (explained in Paragraph 4-l 1).
4-15. ADVANCE, DELAY, DOUBLE PULSE
MODES.
4-16. Three modes of pulse operation are obtained by switching the timing pulse from the Trigger Block­ing Oscillator V103 through combinations of circuits. These circuits are described below first in terms of general operation (Paragraphs 4-17 through 4-26)
and second, as each is used in either PULSE AD-
VANCE, PULSE DELAY, or DOUBLE PULSE (Para-
graphs 4-27 through 4-32).
4-17. PULSE POSITION CIRCUIT.
4-18. POSITION MULTIVIBRATOR. The circuits of
tubes V201A and V202A form a monostable multi-
vibrator which controls the position relationship be­tween the output pulses and trigger output or between both output pulses in DOUBLE PULSE operation. This multivibrator substitutes cathode-coupling with a
common cathode resistor for the usual coupling be­tween plate of V202A and grid of V201A, but still is a monostable circuit. The width of the multivibrator pulse is controlled by range capacitors, C201 through
C205, and the VERNIER control R207. By controlling
the time V202A is cut off, with the range capacitor
and VERNIER, the delay before triggering theposition blocking oscillator V201B is also controlled (V201B
is triggered as V202A starts conducting; see Para-
graphs 4- 19). Tube V104B acts as a screen biasing
supply for V202A.
The output at pin 9 of V202A is a variable width positive pulse which is coupledthrough C209 to pin 6 of V201B.
4-19. POSITION BLOCKING OSCILLATOR. The sig­nal from V202A triggers Position Blocking Oscil­lator V201B at the plate. This signal is coupled through T201 to the grid (pin 7) and the circuit functions in the same way as V103 right half, described in Paragraph 4-11. The output is takenfromthe cathode
as a positive pulse about 30 volts in amplitude.
4-20. PULSE WIDTH MULTIVIBRATOR.
4-21.
The circuits of tubes V206A and V204B form a monostable, cathode-coupled multivibrator, and the circuit functions the same as that described in Para­graph 4-18. The time for whichV204Bremains cutoff is determined by range capacitors C225 through C229 and VERNIER, R257. The output at pin 9 of V204B is
used to drive the stop pulse blocking oscillator V206B
(see Paragraph 4-26). The time delay obtained from the width multivibrator thus determines how long since
4-2
the output pulse started before the stop pulse blocking oscillator returns the pulse to zero (this time is the pulse width).
4-22. TRIGGER OUTPUT BLOCKING
OSCILLATOR.
4-23. Tube V203 and transformer T202 function as an
amplifier-blocking oscillator in a nearly identical circuit as described in Paragraph 4-11 for the circuit of v103.
A signal at pin 2 of V203 is amplified and coupled from the plate through T202 to the grid of the right half. For a positive trigger output, S203 routes
the cathode signal to 5201 and for a negative trigger out, S203 routes the signal from pin 1 of T202 to 5201.
4-24. START-STOP PULSE BLOCKING
OSCILLATORS.
4-25. START PULSE BLOCKING OSCILLATOR. The circuit of V205A and T203 is another blocking oscil­lator working the same way as described in Para­graph 4-11. The signal which triggers V205A plate has been amplified by V204A and delayed by 0.14 microseconds by DL202. The output from thecathode of V205A is a positive pulse of about 35 volts which drives the input to V301.
4-26. STOP PULSE BLOCKING OSCILLATOR. The blocking oscillator of V206B and T204 also is of the same type already described in Paragraph 4-11. The
signal to trigger V206B comes from the width multi­vibrator circuit when V204B starts conducting. The output from the cathode of V206B is a positive pulse of about 35 volts and it drives the input to V303, the
Stop Pulse Spiker.
4-27. PULSE ADVANCE TIMING LOGIC.
4-28. Figure 4-2 shows the timing logic for PULSE
ADVANCE mode of operation. The timing pulse from
V103 goes directly through diode CR207 to the start-
stop pulse circuits (through V204A to V205A, and
through the width multivibrator to V206B). The timing
pulse also goes through CR201 to the grid of V201A
to operate the position multivibrator. The resulting
waveform from the position blocking oscillator is
coupled through C216 to pin 2 of V203. Now the posi-
tion multivibrator is used to effectively delay the trig-
ger output, i.e. the main pulse output occurs in
advance of the trigger.
The pulse width multivibrator
and start-stop pulse blocking oscillators function the same as described previously.
4-29. PULSE DELAY TIMING LOGIC.
4-30. Figure 4-3 shows the timing logic for PULSE
DELAY mode of operation. The V103 timing pulse
goes directly to Cathode Follower V202B andis taken, delayed by 0.4 microseconds by DL201, throughS202B to the trigger output blocking oscillator, to cause a trigger output pulse. The timing pulse has also trig­gered theposition multivibrator circuit throughCR201. The output from V201B goes through CR208 and S202B to the width multivibrator and start-stop blocking oscillators.
This time the position multivibrator has been used to effectively delay the start of the pulse output with respect to the trigger output.

4-31. DOUBLE PULSE TIMING LOGIC.
4-32. Figure 4-4 shows the timing logic for DOUBLE PULSE mode of operation. The V103 timingpulse goes directly through CR201 to the position multivibrator
and directly through CR207 to the start pulse and stop pulse circuitry (i.e. through V204A and also through the width multivibrator). This causes one pulse out­put. Then the delayed timing pulse from the position
multivibrator and blocking oscillator comes through
CR208 to trigger the start-pulse circuitry a second time and another pulse output is formed. The delayed timing pulse from V201B determines the position in time at which the second pulse occurs (i.e. the time between leading edge of pulses). The pulses have the
same variable width since both are controlled by the width multivibrator.
4-33. FORMING AND CONTROLLING
OUTPUT PULSE.
4-34. The fast rise and fall time of the output pulse is
achieved by rapid charging of the input capacitance
represented by the grid of tubes V304 and V305, then
02056-l
rapidly discharging this capacitance to end the pulse. A large current spike waveform is used and the output tubes are held on during the pulse by a bistable type multivibrator circuit. The amplitude of the output
pulse is controlled by varying the output tube screen
supply, by changing the bias levels of the output cir­cuits, and some attenuation at the output,
4-35. START PULSE SPIKER.
4-36. The positive pulse from V205A is coupled through L301, C301, and CR301 to the control grid of v301. The input circuit of V301 changes the dc level of the start pulse and smoothes the transition from triggered on state to the steady stateduring the output
pulse. Diode CR301 discharges the input circuit after
the start spike occurs and C302 discharges through R301 to increase the fall time of the spike. The rise time of the spike is sharpened by clipping diode CR303. Tube V302A is a screen supply for V301. The output of V301 is a current spike which is increased to about
0.5 amp by current step-up transformer T301 and coupled to the input circuit of V304/5 to charge
input capacitance.

spike input. The steady state cutoff bias of V304/5 is set by a voltage divider network including breakdown diode CR326. To keep the output tube conducting after the start pulse, CR326 is taken out of the breakdown area by transistor Q301. Transistor Q301 is triggered on by the other winding of T301 (pins 1 and 2) and held on by bias developed across CR327 and CR328. This clamps the collector voltage of Q301 to the emitter, reducing CR326 voltage to less than breakdown. With Q301 conducting, V302B now supplies a steady 11 ma current to keep diodes CR324/5 conducting, holding V304/5 on.
Then to turn V304/5 off and end the output pulse, the negative spike from T302 through the top winding (pins 1 and 2) discharges the input capacitance rapidly and the other transformer winding
(pins 3 and 4) turns Q301 off. This restores the bias on CR326 and the circuit returns to its original state, ready for the next start spike from V301. The output pulse is taken across a 50 ohm resistancein the plate
circuit of V304/5 for all ranges except 100~. This
50 ohm source impedance, consisting of R405 through R408 in parallel, absorbs reflections from an external system mismatch.
4-41. PULSE OUTPUT AMPLITUDE CONTROLS.
4-42. The circuits changedby switch S401 control the output pulse amplitude in various ways. s401c
switches different breakdown diodes (CR320-322) into the control grid circuit of the output tubes. S401D
changes the bias on screen supply tube V302A in the
start pulse spiker circuit. S401A and S401B are in
the screen supply for the output tubes and this circuit
also affects the pulse amplitude.
Increasing the
Amplitude VERNIER R360, charges C325 from the
cathode of V307 for a quick response to an increase in control voltage. To get a quick response for a decrease in control voltage, V308 discharges C325. Other sections of S401, at the output, switch in attenuator resistors on lower pulse amplitudes.
4-37. STOP PULSE SPIKER.
4-38. The positive pulse from V206B is coupled through L303, and CR308 to the control grid of V303. The input circuit of V303 is nearly identical to that of V301 and the same result is obtained in a negative
current spike at the plate. The output of V303 is
coupled by current step-up transformer T302, but
reversed in phase to that from T301 which initiated the pulse, to the input circuit of V304/5 to discharge the input capacitance.
4-39. PULSE OUTPUT CIRCUIT.
4-40. Parallel output tubes V304/5 are turned on by
the current spike from the top winding (pins 3 and 4) of T301 and then held on by a type of bistable multi­vibrator circuit which includes the output tubes.
Diodes CR324 and CR325 sharpen the rise time of the
4-4
4-43. REVERSING PULSE POLARITY.
4-44. Either positive or negative output pulses are
obtained merely by reversing the connections between
center conductor and shield of the coaxial cable car­rying the pulse. Switch S402 reverses these con­nections. This method of reversing polarity is
pas-
sible because a floating power supply is usedallowing the ground reference to be established at any level.
Inductors L308, L401, and L402 isolate the voltage
supply and prevent the supply from bypassing the
pulse.
Negative pulse outputs occur when the plates of the output tubes drive the center conductor of the coaxial cable and the shield is tied to the OV, isolated supply reference. Positive pulses occur by reversing these connections and placing the center conductor at the OV isolated reference voltage.

e. Connect divider probe to pin 8 of VlO3 (tube
side of R144, 150 n ) and probe cable to scope TRIG
INPUT.
f. Check to see that when PULSE POSITION VER-
NIER is fully clockwise, arrow on knob points to
the black dot on the front panel. If not, loosen set screws,
slip knob to proper position, and tighten

t. Repeat above procedure starting with step n
to minimize interaction between C205 and R210.
Note that with the semi-calibrated VERNIER, reset­ting to exactly 1 or 10 is difficult and this error may seem like interaction between the two adjustments.
5-25. OUTPUT BIAS CURRENT.
a. Set Model 214A TRIGGER MODE switch to EXT. (or set GATE INPUT to GATED position). This is to ensure that no signal can trigger output tubes V304 and V305 during this adjustment pro-
cedure.
CAUTION
If step a is not followed, damage to Model
214A circuit components may result.
b. Refer to Figure 5-6 and locate the wire loop on the bottom side of the output circuit board, A301. The current flowing in this loop is to be measured and an adjustment made if necessary.
c. If using a @ Model 428B, clip the current probe
around the wire loop,
with arrow on the probe
pointing to the nearest side panel. If a conventional
milliammeter is used, the wire loop must be opened
and the milliammeter inserted in series.
To open
the loop, either unsolder one end of the wire from
the circuit board, or slide the insulation to one end and clip the wire.
d, AdjustR344foranindicationof from49to45 ma.
Note
It may appear that interaction is occurring
because the VERNIER has not been reset to the same point as before. Since VER­NIER is semi-calibrated by front panel
markings, consider errors in resetting to “1” or
“10” for above adjustment check.
m. Set VERNIER to ccw extreme and pulse spacing should be less than 5 psec; at cw extreme greater than 110 psec.

Then rotate R30
counterclockwise until relay Kl just begins operation.
h. Rotate PULSE WIDTH VERNIER ccw to stop overload relay operation.
Relay should operate again
as pulse width reaches about 55tisec (5. 5 cm). 5-28. TROUBLESHOOTING.
5-29. The information suggested in Paragraphs 5-30 through 5-34 is provided as a front panelcheck toaid in locating-possible faulty components in the shortest
possible time.
In each solution it is assumed that active components such as tubes, transistors and diodes are defective, which may not be true in every case. Waveforms, dc voltages and ohmmeter checks in that order can be used to locate faulty passive com-
ponents such as resistors and capacitors. 111 locating
any problemin the Model 214A, check power supply voltages first since they affect several circuits.
5-30. TRIGGER MODE CHECKS.
a. If the Model 214Acan be triggeredwith TRIGGER
MODE set to INT. but not in EXT. or MANUAL posi-
tions, replace DSlOl.
b. If the Model 214A can be triggered with TRIGGER
MODE setto INT. or MANUAL but not in EXT. posi-
tions, replace V101.
c. If the Model 214Acan be triggered with TRIGGER
MODE set to EXT. or MANUAL but not in INT. posi-
tions, replace CRlOl.
d. If the Model 214A can not be triggered in any of
the TRIGGER MODE positions, check waveforms 1
through 4 in that order to locate faulty component.
e. If the Model 214A will not gate on a minimum of
8 volts, check V103.
f. If V103, pin 8, has no output,check the -7.8 v bias on V103 pins 2 and 7, and check the cathode po­tential on CR103 (should
be
positive).
5-31. PULSE CONTROL CHECKS.
a. If a trigger can be obtained at the TRIGGER OUT­PUT when PUIS E ADVANCE/PULSE DELAY/DOUBLE PULSE control is set to PULSE ADVANCE or DOUBLE PULSE, but not when set to PULSE DELAY, replace
v202.
b. If a trigger can not be obtained with PULSE, ADVANCE/PULSE DELAY/DOUBLE PULSE control in any position, replace V203 or check waveforms 10 through 12.
c. If PULSE POSITION control does not reposition
pulse, check waveforms 4 through 8 to locate faulty
component.
d. If PULSE WIDTH control does not vary pulse width, check waveforms 17 through 22 to locate faulty component.
e. If pulse width or pulse position suddenly changes
greatly when the VERNIERS are varied, replace diodes
CR202/203 or CR212/213, depending on which circuit
is faulty.
f. If there are no start or stop spikes (plates of V301 and V302) check diodes in grid circuits (CR301,
302, 303, and CR306, 307, 308 and 309).
5-32. OUTPUT CIRCUIT CHECKS.
a. If a pulse is present at TRIGGER OUTPUT but not at PULSE OUTPUT, check waveforms 13 through
16 and 23 through 26 in the Start-Stop Pulse circuits, and dc voltages in the output circuit to locate faulty components.
b. If output pulse amplitude will increase but does
not decrease, replace V308.
c. If output pulse will not hold its amplitude (sags),
check for blown fuse F2, or C325 for leakage.
d. If the output pulse appears as two spikes (start and stop spikes), check Q301, CR326, CR327, and CR328.

e. Poor rise time is usually caused by weak V301
or faulty diodes CR324 and CR325.
f. If Amplitudepots, R353, R354, or R355 willnot adjust the 10 v, 20 v, or 50 v ranges, respectively, to the required amplitude, first check diodes CR320 thru CR322. Thencheckbias adjustments R344 (par. 5-25) and R363 (par. 5-26, steps m through p) for proper bias on output tubes, V304 and V305.
g. If excessive overshoot exists on high amplitude
ranges, replace CR324 or CR325. 5-33. POWER SUPPLY CHECKS.
5-34. The power supplies can be checked for malfunc-
tions by making dc voltage measurements. If front panel control settings are made, as indicated in
Schematic Notes, before measurements are made, f’O” reference and chassis ground will be the same.
5-35. REPAIR AND REPLACEMENT. S-36. GENERAL.
5-37. Refer to Figures 5-6 through 5-11 for locations and identification of components on etched circuit boards in the Model 214A.
For components not identi­fied in these figures, determine the circuit location intheinstrument and refer to the schematic diagrams for reference designator.
Section VI contains a com-
plete list of reference designators for electrical com-
ponents and the Hewlett-Packard Company stock
number for the item. 5-38. SERVICING ETCHED CIRCUIT BOARDS.
5-39. Etched circuit boards used in the Model 214A
have components onone side of the board with aplated
conductive layer of metal through component holes. @ Service Note M-20D also contains useful information on etched circuit repair.
The important steps and
considerations are:
a. Usea lowheat (30 to47.5 watts, less than800”F idling temperature), slightly bent chisel tip (l/16 to l/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 ironon the component lead on either side of the board andpullingup onthe !ead. 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 toprovide a heat sink between the soldering iron and component.
c. If a component is obviously damaged or faulty,
clip the leads close to the component and then unsolder
Ihe leads from the board.
d. Large components such as potentiometers and
tube sockets may be removed by rotating the soldering
iron from lead to leadand applying steady pressure to
lift the part free (the alternative is to clip the leads of
a damaged part).
e. Since the conductor part of the etched circuit boards is a metal plated surface, covered with solder, use care lo avoid overheating and lifting the conductor 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.
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.
g. Shape the new component leads and clip to
proper length. Insert the leads in the holes andapply heat and solder, preferably on the conductor side.
S-40. PERIODIC MAINTENANCE.
5-41. GENERAL. 5-42. The air intake fan motor needs little lubrication
or preventive maintenance.
About once a year, place
one or two drops of light oil on the shaft at the front
and rear bearing supports.
It is also recommended as preventive maintenance that the interior of the in­strument be cleared of any accumulated dust when
necessary.

5-44. Inspect the air filter (rear of instrument) regu-
larly and clean it before dust can restrict air flow. Air flows from outside the instrument in through the filter.
a. Remove the filter and wash it inwarm water and
detergent.
b. Dry the filter thoroughly and coat with filter adhesive preparation recommended in Paragraph 2-10.
