Channels. Large amplitude signals can be attenuated
by using the ATTEN switches. Setting the attenuator
switches increases the trigger levels and the
hysteresis voltages by factors of 1, 10, 100. If input
signal levels are unknown, the initial measurements
should be made with the attenuator switches set
to XI00. The attenuator settings are then reduced
until a stable, useable measurement is obtained.
9D-3-5. SLOPE Switches (both Channels).
The
slope switches allow the selection of triggering on
the positive (+) or negative (-) slope of the input
signals (see Figure 9D-3-1).
9D-3-6. LEVEL Controls (both Channels).
The
level controls allow adjustment of the triggering
point on the input signal waveform. With the LEVEL
controls set to PSET or "0", triggering is centered
about zero volts. The voltage range over which
triggering may be set is -1 volt to +1 volt times
the ATTEN switch settings (±1 V to +100 V).
9D-3-7.
AC-DC Switches (both Channels).
The
AC-DC switches select ac or dc coupling. In AC
position and PSET, triggering is centered about
ac-zero, and dc components on the signal have no
effect. In DC position and PSET, triggering is
centered about 0 volts dc on the signal.

of the START Channel "A" and the enabling of the STOP Channel "B" (see
Figure B). This delay may be used to
measure relay or other mechanical
switch timing sequences without error
due to contact bounce. It may also be
used for measurements on pulse trains;
for example from the start pulse to a later
pulse, in the presence of intervening pulses.
To use the DELAY, proceed as follows:
a.
If the desired delay is known, it
may be set and measured by
selecting T.I. A to B and CHK and
setting DELAY control to the desired
delay time. The measurement may
then be made by switching COMSEP-CHK in step 5.

If the input signals are pulse trains,
it is possible to select a pulse out of
the train by increasing the DP]LAY
from full ccw; the measured time
interval will increase in steps as the
delay falls after successive pulses
in the train.

For maximum flexibility and ease of
interpretation, an oscilloscope may be
used to set up the measurement (as
shown in Figure A). The DELAY
OUTPUT is used to trigger (he time
base and intensity modulate the display (see Figure A). For a repetitive
waveform, the Channel A input may
fall during the display cycle, and
therefore might not initiate a measurement. The GATE output may be
substituted for the DELAY OUTPUT;
this allows intensifying the actual
measurement rather than the delay.
If the inputs are common, the GATE

be displayed on the second channel

THEORY OF OPERATION
9 D - 4 - 1 . INTRODUCTION
9D-4-2.
This subsection describes the theory of
operation for the 5304A Timer/Counter. Basic operation of gates, certain amplifiers and integrated
circuits is found in Section IV of the 5300A portion
of the manual.
9D-4-3. To simplify measurement making refer to
operating information starting with Paragraph 9D-3-1
for optimum adjustment of various controls.
9 D - 4 - 4 . I N P U T AMPLIFIERS A N I ) MODES
O F OPERATION
9D-4-5. CHANNEL A. The Channel A input signal
is applied to front-panel INPUT A jack and attenuated by A2 attenuator assembly (XI, X10, X100)
and sent to Al Channel A input amplifier. The
A2 Attenuator Board Assembly also contains the
AC-DC switches, SLOPE switches, and the LEVEL
controls for both channels. The input signal is sent
through A2 to the input of matched FET sourcefollower pair, Q2 and Q4. Diodes CR2, CR4 are
limiters for Q2 inputs.
9D-4-6. One side of the FET source-follower pair
(Q2) receives the input signal from A2J2 and the
other side (Q4) is connected to LEVEL A triggerlevel control A2R9. Q2 and Q4 are connected to
differential amplifier Q6 and Q8 respectively and
provides level shifting and gain of approximately
.3 for Channel A signals. Resistor R20 is a dc
balance for differential amplifier Q6 and Q8.
9D-4-7. The output from Q6, Q8 drives another
differential amplifier, U24B. The U24B output is
shaped by Schmitt-Trigger U24A and level-shifted
(ECL to TTL) through U21B, Q12 combination.
The U21B expander output is used to obtain sufficient signal swing to drive Q12.
9D-4-8. CHANNEL B. The Channel B input signal
is applied to front-panel INPUT B jack and attenuated by A2 Attenuator Assembly (Xl, X10, XI00)
and sent to Al Channel B input amplifier. The A2
Attenuator assembly also contains the Channel B
coupling switches, slope switches and the Channel
B level control. The Channel B signal is routed
through A2 to the input of matched F E T sourcefollower pair Ql and Q3. Diodes CRl, CR3 are
limiters for Ql inputs.
9D-4-9. One side of the Channel B FET sourcefollower pair (Ql) receives the input signal from
A2J1 and the other side (Q3) is connected to LEVEL
B trigger level control A2R10. Q5 and Q7 are connected to differential amplifiers Qf> and Q7 respectively and provide level-shifting and gain of
approximately .3 for Channel B signals. Resistor
R19 is a dc balance for differential amplifier Q5
and Q7.
9D-4-10. The output from Q5, Q7 drives another
differential amplifier U23B. The U23B output is
shaped bv Schmitt-Trigger U23A and level-shifted
(ECL to TTL) through U21A, Q l l combination. The
U21A expander output is used to obtain sufficient
signal swing to drive Q l l .
9D-4-11. VOLTAGE REGULATION. Transistors Q9,
Q10 provide regulated, low-ripple dc power to the
amplifiers and time interval hold-off circuits.
9D-4-12. SLOPE SELECTION. Slope selection for
Channel A is accomplished by using U19C, U20C,
and U20I) in conjunction with A2S7. Slope selection
for Channel B is accomplished by using U19I),
U20D, and U20A in conjunction with A2S(>.
9D-4-13. CHECK MODE.
In the CHECK mode,
the operation of the 5300A 10 MHz crystal oscillator
and counting logic and the 5304A gating logic is
verified. When A2S1 is in CHK mode, ground is
applied to U18A(2), U18I)(12), and U13C(5). The
10 MHz clock from the 5300A A1J1(16) is routed
through the 5304A AlPl(16) and sent to U12D(12).
The Channel A switch (U18B) and Channel B switch
(U18C), gate the 10 MHz clock signal through. The
Channel A switch output is also gated through U12B
and U16B and is available as the Fl signal at
A1P1(5).
9D-4-14.
FREQ A MODE.
In the frequency
measuring mode, with the "Function" switch S2 in
any of its four frequency measuring positions
(FREQ AUTO, .IS, IS, 10S) the Channel A input
signal is gated through "Channel A Slope Selection"
switch comprised of U19C, U20C, and U20B. The
input signal is then routed through another "Channel
A" switch made up of U18A and U18B.
From
U18B(6) the Channel A input signal is gated through
U12B and U16B as the Fl signal to the 5300A
mainframe which controls the opening and closing
of the main gate. The 10 MHz clock signal from
9D-4-1
Model 5304A
Theory of Operation
the 5300A m a i n f r a m e at A1 Pi(16) is routed through
U12C as the F2 signal to control the time base,
which clocks the opening and closing of the main
gate.
9D-4-15. The positive-going edge of a negative pulse
from U17E is the MAX TIME signal. The MAX
TIME signal a t A1 Pi(17) triggers a display cycle in
the 5300A mainframe. This negative-going pulse
can be generated from one of two sources.
One
of the sources is the positive-going edge of the
MGFF line at A1P1(12) which indicates the closing
of the 5300A main gate. This signal is inverted
through U17D and differentiated l>y CI4 and R69.
CR18 is a clamping diode to shorten the differentiation
recovery time.
The negative pulse
of the differentiated waveform, gates U16A " o n "
and the narrow positive-going pulse is inverted
through U17E as the MAX TIME signal.
9D-4-16. The TIME BASE O U T signal at AlPl(18)
comes from the 5300A m a i n f r a m e and is buffered
by Q18 then gated through U14C, U1HA, and inverted
through U17E as the MAX TIME signal.
9D-4-17. The positive-going edge of the negative
pulse at A1PK17), indicates the display cycle h a s
been triggered.
9D-4-18. PERIOD AVG A MODE. In period a v e r a g e
mode the "function" switch S2 enables U l A , U6D,
U12C, and U14A. The Channel A signal is routed
through "Channel A Slope Selection" and " C h a n n e l
A Switch" at U18B(6). The signal is then gated
through U16C and is available at AlPl(21) a s the 1
MHz TIME BASE. The CLOCK signal at A1P1(16)
is gated through U12A, U16B a s the F l signal to
be counted.
9D4-19. Flip-flop U4A prevents very narrow pulses
from triggering the time base but not the main
gate. The first Channel A pulse after the I N H I B I T
signal goes high at the end of the display cycle
"clocks" U4A(5) to a high state and enables U16C.
The next positive-going edge of the Channel A signal
is gated through U16C a s the 1 MHz T I M E BASE
INPUT signal. The main gate is then closed by
one of two events. The first event is: The 9 signal
line from 5300A, U3 COUNTER, goes low, and
enables the main gate in the 5300A, U5 CONTROL,
to close on the next LOG pulse. When the 9 line
goes low it indicates t h a t the display is 9% full.
The main gate closes at the end of the next decademultiple of the input signal to prevent overflow. The
second event is:
The TIME BASE O U T signal
(A1P1(18)) from the 5300A, U4 TIME BASE goes
9D-4-2
low indicating the I0 a periods have been counted.
The main gate closes because no more counts can
be stored in the 5304A exponent counter U8A and U8B.
The exponent counter counts the number of decadetransitions of the input signal t h a t have been
counted (1, 10, 100, 1000 input transitions or exponent counts of 1, 2, 3, 4).
9D-4-20. The LOG O U T P U T signal (generated by
5300A, U4 TIME BASE) is active in Frequency and
Period Average Modes and provides pulses to open
and close the main gate. Following a display cycle
and reset, the first LOG pulse opens the main gate
and a following LOG pulse will close the gate only
after a 9 or MAX TIME low signal enables the
closing of the main gate flip-flop.
9D-4-21. O P E N / C L O S E A MODE. In open/close
mode, with the "function" switch S2 in O P E N /
CLOSE position the main gate is opened and closed
by successive actuations of pushbutton switch SI.
The Channel A input signal is gated through "Slope
Selection" switch U19C, U20B, and U20C to " C h a n nel A Switch" U18A and U18B.
9D-4-22.
T h e Channel A input signal is gated
through U12B, U16B to be counted. U4B "clocks"
on successive actuations of the SI O P E N / C L O S E
switch.
When U8B(9) output is low the 5300A
main gate is opened (through U19B).
When
U4B(8) output is low the 5300A main gate is closed
(through U14D and U22A). When the "Function"
switch S2 is in a position other t h a n O P E N / C L O S E ,
the U4B Preset and Clear lines (U4B pins 10 and 13
respectively) are set through U10A and B, so that
IJ4B, Q and Q output (U4 pins 9 and 8) are high.
9D-4-23. TIME INTERVAL A-B MODE.
In the
time interval mode, the "function" switch S2 may
be set to a n y one of six time-interval positions
(.1 /Jsec to 10 msec). The 5300A main gate is opened
by a Channel A transition and closed by a Channel B
transition. Switch A2S1 enables the input signals
to be taken from separate sources or from a
common source.
9D-4-24.
The Channel A signal, after passing
through A2 Attenuator Assembly, is processed
through Channel A amplifier, Q2 Q4 and differntial
amplifiers Q6, Q8, and U24B. T h e U24B output is
shaped through U24A Schmitt-Trigger and sent
through an ECL-to-TTL level-shifter (U21B, Q21)
to the Channel A Slope Selection circuits (U19C,
U20C, U20B).
9D-4-25. The output from U20B(4) is gated through
Channel A switch, comprised of U18A and B. The
Channel A signal "clocks" U15B which is gated
through U9C, U19B, and opens the 5300A main gate.
During the gate-open time, the TIME BASE O U T
Model 5304A
Theory of Operation
signal from the 5300A A1J 1(18) is gated through
Q18, U17F, U9B, and U16B to be counted (except
in the .1 fjsec position, where the 10 MHz clock is
gated through U12A and U16B). The TIME BASE
OUTPUT signal is a 10 MHz clock signal divided
down by the time base to allow counting in increments of 1 fjsec, 10 fjsec etc.
9D-4-26. The main gate closes when Channel B
"clocks" U15A and a display cycle is initiated by
the positive-going edge of the M G F F signal at
A1P1(12). This signal is inverted through U17I)
and differentiated by C14 and R69. The negative
pulse of the differentiated waveform gates U16A
"on" and the narrow positive-going pulse is inverted
through U17E as the MAX TIME signal.
9D-4-27.
At the end of the display cycle, the
RESET signal at AlPl(15) is inverted through
U13E and sets U15B(9) low. U15A(5) is set high by
the PRESET signal a t U15A(4). The INHIBIT signal
goes "high" and sets U15B(12) so that U15B changes
states on the positive-going transition from U18B(6).
This produces two results:
1. U9C(8) goes low which set the OPEN signal
at A1P1(10) low through U19B and opens
the 5300A main gate.
2. Q16 turns off and allows C12 to charge
through R43 and R61.
9D-4-28. Transistor Q15 is an emitter-follower input to Schmitt-Trigger Q13, Q14. The output from
Q13 is level-shifted by CR15 and inverted by Q17.
Q15, 14, 13, and 17 form a one-shot multivibrator
with a very wide timing range. U15A cannot change
states until Q17 output goes low; then U15A(3) is
clocked to its opposite state by the positive transition of U18C (Channel B switch output).
The
U15A(5) output is gated and inverted through U14I)
and U22A. This causes the CLOSE signal line to
go low which in turn closes the 5300A main gate.
9D-4-29. The 5300A main gate cannot be re-opened
until U15B is cleared by the RESET signal at
A1PK15) and until the INHIBIT signal at AlPl(8)
sets U15B(12) high. U15B(8) goes high a t RESET
and turns on QI8 which discharges C12.
When
R43(S2) is open (full ccw), CI2 is not charged
up and the one-shot time-interval is very short
(about 200 nsec). The time-interval is the interval
from the time U15B(8) goes low and Q17 collector
goes low.
9D-4-30. A buffered DELAY OUT signal is provided
at J 3 and may be used for intensifying the oscilloscope Z axis which permits observing the start
and stop period in a time interval measurement.
A buffered GATE OUT signal is also provided at J4
which permits observing the gate signal duration
in a time interval measurement
9D-4-31.
EXPONENT COUNTER; EXPONENT
STORAGE. Outputs from the 5300A, U5 EXP line
are appli< J to exponent counter U8A, U8B "Clock
input". The RESET signal at A1 Pi(15) clears USA
and presets U8B for another measurement.
Exponent signals "clocked" into U8 indicate length
of measurements (10 ms, 100 ms, or 1 sec in
FREQ AUTO mode; 1, 10, 100, 1000 periods in
PERIOD AVG mode).
During the measurement
cycle, information is transferred into U7A, B
exponent storage by the TRANSFER signal. Therefore, the displayed measurement, the decimal point
and the units, change simultaneously.
9D-4-32. Exponent storage U7A, B is disabled (both
flip-flops are cleared), except in AUTO measurements, by U6I). Manual reset also clears U7A, U7B,
the decimal point and measurement units.
9D-4-33.
The remainder of the gates with the
exception of U5B provide time base, decimal point,
annunciator, and function decoding. The U3A output is high in any of the four frequency-measuring
positions. U5B locks out the LOG OUTPUT signal
in OPEN CLOSE A and TIME INTERVAL A B,
when the open and closing of the main gate is controlled by OPEN and CLOSE.
9D-4-34. Q19 normally turns off the 9 line except
during frequency Auto or Period Average; this
allows overflow to occur, if desired, in manual frequency position.

9 D - 5 - 1 . INTRODUCTION
9D-5-2.
This section contains maintenance and
service information for Model 5300A/5304A Timer/
Counter. Included are performance check procedures
and tests to localize, isolate, and locate defective
components.
9 D - 5 - 3 . RECOMMENDED TEST E Q U I P M E N T
9D-5-4. Test equipment recommended for performance checks, maintaining, troubleshooting and
servicing the 5300A/5304A Timer/Counter is listed
in Table 5-1 of 5300A portion of the manual. Test
equipment with equivalent characteristics may be
substituted for equipment listed.
9D-5-5. INSTRUMENT ACCESS
9D-5-6. For access to plug-on assembly, separate
the 5300A from the 5304 A as follows:
a. Turn ac power OFF and disconnect power
cord.
b. Pull the two-side casting latches fully rearward (it is necessary to press the latch handles
gently away from the center of the instrument to
unlock them).
c. When latches are fully extended rearward, the
5300A and 5304A castings should be separated by
cbout '/g-inch.
d.
Lift the 5300A gently away from the 5304A.
e. Separate 5304A Al BOARD ASSEMBLY from
5304A casting as follows (refer to Figure 9D-5-1):
1.
Press rear, plastic-nylon retaining clips on
each side of 5304A casting and lift the rear
of the Al Board Assembly to release it
from the casting.
2.
Press front plastic-nylon retaining clips on
each side of 5304A casting and lift the front
of the Al Board Assembly to release it
from the casting.
3.
Lift Al Board Assembly from the casting.
f. Mate the 5304A, Al Board Assembly to 5300A
and reapply ac power.
g. To reinstall the Al Board Assembly into the
casting reverse procedure of steps d through f.
9 D - 5 - 7 . PERIODIC MAINTENANCE
9D-5-8. To determine if the 53O0A/53O4A is operating properly within specifications, perform the InCabinet Performance Checks listed in Table 9D-5-1.
These checks may also be used for the 5300A performance checks when the 5300A/5304A combination
is used.
9 D - 5 - 9 . MAINTENANCE A N D REPAIR
9D-5-10. BOARD REMOVAL. When removing the
printed circuit board for replacement, repair, or
servicing, always remove ac power and separate
the board from the casting using Paragraph 9D-5-6
steps a to e.
9D-5-11. COMPONENT REPLACEMENT. When
replacing a circuit board component use a low heat
soldering iron. Heat must be used sparingly as
damage to the circuit foil may result. Mounting
holes may be cleaned out with a toothpick while
heat is applied. Connection should be cleaned with a
cleaning solution after component removal and
replacement.
9D-5-12. INTEGRATED CIRCUIT REPLACEMENT.
Two methods are recommended for removing
integrated circuits:
a. Solder Gobbler.
Solder is removed from
board by a soldering iron with a hollow tip con
nected to a vacuum source. The IC is removed
intact so it may be reinstalled if diagnosis is
wrong.
b. Clip-Out. This method is used when an IC
is proven defective. Clip leads close to case, apply
heat and remove leads with long nose pliers.
Clean board holes with a toothpick and cleaning
solution.
9 D - 5 - 1 3 . I N S T R U M E N T TROUBLESHOOTING
9D-5-14.
Trouble isolation can best be accomplished by first obtaining all possible information
from the controls, connectors, and indicators on the
5300A and 5304A, then logically using this information to locate the defective component.
If the
