Paragraphs 1·6 to 1·10
available at'fixed amplitudes of ±10V (binary) and
3.16V rms (Gau:lSi, an), and a precision RMS AMPLI·
TUDE control prbvides a variable output ranging
from 0.1V up to the level of the fixed outputs.
When operating in the' pse
, udo·random , mode, the
hp 3722A provides timing ,signals (sync and gate
pulses) for the control of exttlrnal meast:rements.
1·6
OPTION 01
1·7 Time .Jverages taken over one period of a
pseudo-random sequence are normally independent
of the point in time at which the averaging starts.
However, when the test signal is contaminated by
background disturbances, such as steady drifts, the
result of the averaging measurement can be in error.
In such cases, the magnitude and sign of the error
depend critically on the starting poin'( of the averag·
ing process. In Option 01 models, the starting point
(identified by the sync pulse) is optimised for each
of the seven shortest sequences (15,31, 63, 127,
255, 511 and 1023).
1·8 A standard instrument may be converted into
an Option 01 version simply by the removal of a
wire link and the insertion of a circuit board (the
sequence advance assembly) into a pre·wired socket
on the main chassis. The conversion procedure is
described in Section VII.
1·9
INSTRUMENT IDENTIFICATION
1-10 A" identification plate on the rear panel of
the instr linent carries a two-section, eight·digit
serial nUlllber. The first three digits form the
serial prefix number and the last five digits refer
to a speciiic instrument. If the serial prefix on
vour instrume.1t is not as given on the title page
of this manual, there are differences between the
manual and your instrument: these differences are
described, together with manual errata, in the yellow
change sheet included with the manual. For the
latest information on the instrument, contact your
nearest Hewlett·Packard field office. Ir, any corn·
munication with the Company, specify model
number and complete serial nUlnber.

2-4 If the shipping carton is damaged, ask that the
carrier's agent be present whEn the instrument is
unpacked. Inspect the instrument for damage
(scratches, dent, broker. '<nobs, etc). If the instru·
ment is damaged or fails to meet specifications
(Performance check, Section VI, notify the carrier
and the nearest Hewlett·Packard field office imme·
diately (field offices are listed at the back of this
manual). Retain the shipping carton and the padding
material for the carrier's inspection. The field office
will a rrange for the repair or replacement of '{our
instrument witho:Jt waiting for the claim against
the carrier t o be settled.

OPERATION
3-1 INTRODUCTION
3·2 Switch·on instructions, together with (l sum·
mary of the push·button control functions, are
given in paragraphs 3·3 to 3·7. Paragraphs 3·8 to
3-37 describe in detail the BINARY and GAUSSIAN
outputs from the hp 3722A, and the effect upon
them of the CLOCK PERIOD and SEQUENCE
LENGTH controls. Some description of \he noise
generation mechanism is included, � this is essential
user information. Details of timing outputs from
the hp 3722A are given in paragraphs 3·38 , to 3-4 1,
and a summary of all controls and outputS is given
in the text related to Figure 3·18.
'
•
3-3 SWITCH·ON PROCEDURE
3-4 Essential steps are as follows:·
(1)/ Check line voltage selector on rear panel: set
as appropriate (115 or 230). Connect supply.
(2)
(3)
�t CLOCK switch on rear panel to INT (or
EXT if an eY-ternal clock is to be used to time
3722A: for specifications of external clock,
refer to Figure 3-13).
Set CONTROL
' selector on rear panel to
LOCAl.
(4) Complete, if required the rapid functional
check detailed in Table 3·1.
3-� , PUSH·BUTTON CONTROLS
3-6 HOLD and RESET. Either of these push·
buttons, .when operated, stops, the supply of shift
pulses to the shift register (paragraph 3·9). and thus
inhibits both noise outputs (binary and Gaussian)
from the 3722A. The HOLD button allows the
generator to be stopped at any point in a pseudo­
random sequence; when the instrument is re-started,
by operation of the RUN button, noise generation
is resumed from the point in the sequence at which
it ceased. The RESET button performs two func·
tions - it stops the supply of shift pulses and drives
the shift register to a pre·determined state. Both
HOLD and RESET uperations are illustrated in
Figure 3·1.
,3-7 GATE RESET. When operated, the GATE
RESET control primes a store circuit which, on the
following sync pulse, initiates a gate Signal. The
gate interval depends on (1) the selected duration of
pseudo-random sequence, and (2) the setting of the
02182-1
'SEQUENCES PER GATE INTERVAL' control on
the front panel: the latter control can be set for I,
2, 4 or 8 sequences. Thus wi th a sequence length of
15 and clock period of 1 second (sequence duration
= 15 seconds), the gate signal lasts for 15, 30, 60 or
120 second�, depending upon the setting of the
control. The gate signal falls from +12.5V to zero
at the start of the gate interval, and returns to
+12.5V at the end. A relay contact version of the
gate signal is also provided.
3-8 BINARY OUTPUT
3·9 GENERAl. The binary output is generated by
a shift register which is triggered at regular intervals
, by shift pulses derived from a crystal·controlled
clock. A change in the output level (from binary
'I' to binary '0', or vice-versa) can occur only when
the shift register receives a shift pulse: in the interval
between shi,ft pulses, the output remains at a con·
stant level.
'
3-10 The binary signal is available, at fixed ampli­
tude, frorj1 the BINARY connector on fro;')t and
rear panels. Amplitude of the 'fixed' output is
numinally ± 10V. Note that a binary signal of
± 10V has an rms amplitude' of 10V. Logic
definitions used in this section are:
Binary 'I'
Binary '0'
-10V
+10V
Important characteristics of the binary output are
as follows:
Output impedance < IOn
Luad impedance
lkn minimum
Rise time
< lOOnS
3-11 The binary Signal is available, from a 600n
impedance source, at the VARIABLE OUTPUT
connectors on front and rear panels. The red RMS
AMPLITUDE control selects one of four multiplier
ranges, and the black control selects one of ten
intermediate steps from x 0. 1 to x 1.0. Multiplier
.ra�ges are:
± 10V, ± 3. 16V ( = ±v'IOV). ± 3V and ± IV.
NOTE
These are open·circuit �mplitudes (i. e. if
the VARIABLE OUTPUT is connected
to a 600n load, the voltage across the
load is half that indicated by the RMS
AMPlITUD� controls).
3·1
Paragraphs 3-1 2 to 3-1 4
3-1 2 A relay-contact version of th& binary signal is
available (rear panel BINARY RELAY binding posts)
when the selected clock period is l OOmS or greater.
3-1 4 Pseudo-random, 'maximum length' type, bin­
ary sequences (p. r.b.s.) generated by the hp 3722A
are described in terms of the number of clock
periods (or bits) they contain, this being a function
of the number of shift register stages involved in
generat:on of the sequence (a maximum of 20
stages is connected into the feedlJack loop which
establishes the length of sequence). The length of
a sequence = N bits = 2n - 1 . where n is the num­
ber of stages in the feedback system. Thus with
3-1 3 PSEUDO-RANDOM MODE. in the pseudo­
random mode, the shift register generates repeated
sequences (or patterns) of. binary ones and zeros,
the form and length of the sequence being establish­
ed by feedback ';onnexion to the first stage of the
register. Feedback selection is made by the SE­
QUENCE LENGTH switch.

Continuous spectrum of random

3-24 RANDOM MODE. When the SEQUENCE
LENGTrf switch is set to I N F I N ITE, the shift
register feedback loop is disconnected, and the first
stage of the register is controlled by a noise source
giviny a truly random output. Triggering of the shift
register remains under the control of the clock.
Just before each shift pulse, the random signal is
sampled by a level detector which decides, on
arrival of the shift pulse, whether a . , . or '0' is to be
placed in the first stage of the register. Since the
random signal is non·periodic, there is no repeated
pattern in the resulting series of ones and zeros from
the register (i.e. N is infinite). In this 'random'
mode, the spectrum (Figure 3-6) of the binary out·
put is continuous (it contains no discrete harmoni-:s)

the GAUSSIAN connector is a series of identical

are the same as those for pseudo·random binary
sequences, given in Table 3·1 , I n the random mode,
the spectrum of the Gaussian output is continuous,
and is the same shape as the envelope of the pseudo·

period have the same effect on the Gaussian noise

intermediate steps from x 0. 1 to x 1 .0. Multiplier
ranges are:

3.16V rms is obtained at both the third and
fourth (fully cw) positions of the red control.
NOTE
These are open·circuit amplitudes (i.e. if
the VARIABLE OUTPUT isLonnected to
a 600n load, the voltage, across the load
is half that indicated by the RMS AMPLI­
TUDE controls). .
3-34 PROBABILITY DENSITY FUNCTION. Figure
3-9 shows that the probabiliw' density function
(p.d.f.) of the Gaussian output, when d,erived from
the longer sequences, is a close approximation to
the normal curve" , Also shown in Figure 3-9 are
error plots for the p.d.f.'s of first and second'deri­
vatives of the Gaussian signal obtained with ,N =
32767: these p.d.f.'s also show unusually small de­
partures from the normal curve. Freedom from dis­
continuities in the signal, evan after two differen­
tiations, is achieved by second order analog filtering
of, the Gaussian output: this feature applies to all
Gaussian noise bandwidths above 0.05Hz.
3-35 In the pseudo-random mode, measurements of
p.d.f. are taken over one complete period . (T =
N.:.Tl, or all integral number of periods, of the
noise. An important feature of pseudo-random
noise is the complete absence of statistical fluctua­
tions. All sequences generated with the same settings
of SEQUENC!: LENGTH and CLOCK PERIOD
switches are identical, and all must therefore have
the same p.d.f.
3-36 For sequence lengths below N , = B191; the
p.d.f. shows significant departures from the normal
curve. Two typical examples of this are shown in
Figure 3-10.

versions of the instrument. the point i n tlie sequence
at which the sync pulse cccurs is optimised (for
the seven shortest sequences. III = 1 5 to N = 1023)
such that the first time moment of the p.r.b.s with

3-41 GATE. The gate facility is used for the syn·
chronouscontrol of external measuring processes ­
in particular. when the process is required to last
for a selected number of sequences 0, 2. 4 or 8).
Duration of the' gate is set by the Ij·position
SEQUENCES PER GATE INTERVAL switch on
the front panel. Operation of the GATE RESET
push·button initiates the gate signal. which starts
on the following sync pulse and ends on the sync
pulse marking completion of the selected number
of sequences.
'
The gate signal is available at the GATE connector
and GATE RELAY binding posts on the rear panel.
NOTE
The gate meChClnism is a one-shot device:
only one gate signal' is . generated per
operation of the GATE RESET button.

Shows the frequency of the fundamental (first harmonic) given by combinations of I"S and
3.33"S clock periods with all possible sequence lengths from 1 5 to 1048575. For fundamental
frequencies given by clock periods other than I"S and 3.33/1S, multiply the listed frequency by
the appropriate power of 1 0.
Example A
Find the fundamental frequency given by clock period 1 mS and sequence length 1023.
Listed frequency for clock period I"S and sequence length 1023 = 977,517Hz.
l mS = ljlS x 1 03, 1 50 the fundamental frequency with l mS clock period is one thousandth of"

Example B
Find the fundamental frequency given by clock period 333"S and sequence length 8191.
Listed frequency for clock period 3.33"S and sequence length 8191 = 36.6256Hz.
333"S = 3.33"S x 1 02, 50 the fundamental frequency with 333"S clock period is one hundredth

(2) R U N control. Push-button, push·pull coupled
to the HOLD and ' RESET buttons. For the hp
'3722A to generate outputs, the RUN button must
be 'in' (this allows the shift register to operate).
HOLf) control. Push·button which, when op­
erated, stops the shift register and thus holds the
outputs at a steady dc level.
(3)
BINARY (fixed output) connector. Two-level
signal taken from one stage of the shift register.
Signal amplitude Is tl0V, Impedance less t:lan
Ion (because signal amplitude Is constant, total
output power is constant, regardless of CLOCK
P�RIOD and SEQUENCE LENGTH settings).
(4)
(5)
GAUSSIAN (fixed output) connector. Smoothed
m'lltl-Ievel signal derived from shift register outputs.
Signal amplitude Is 3.16V rms (regardless of GAUSS­
IAN NOISE BANDWI DTH setting), and Impedance
is less than I n .
(6) GAUSSIAN ZERO control. Preset potentio­
meter for adjusting the mean dc level of the Gaussian
signal. Range of adjustment Is approximately t50mV.
VAR IABLE OUTPUT connector. Variable amp­
litude output of either binary or Gaussian signals
(selection by slid" switch (811. Output impedance
600n: amplitude controlled by concentric switches
(9).
(7)
VARIABLE OUTPUT selector. Slide switch
r.onnects either the tl0V binary or the 3.16V rms
Gaussian signal via the amplitude controls to the
VARIABLE PUTPUT connector.
(9) RMS AMPLITUDE controls. The red control
selects one of four 'full scale' multiplier ranges, and
the black control selects one of ten Intermediate
steps from xO. l , to x 1 .0. The red control selects
the same full scale rms values for both Gaussian and
binary outputs on !he three lower ranges (1 V, 3V
and 3.16VI, but only the binary signal is available
at the 10V level: the x l 0 position of the red control
selects t l 0V binary and 3. 1 6V rms Gausslan.

P E R I OD control. 18·way selector de­
' termines, thq timebase frequency, and thus controls
. , ' 'the'steppi'rig rate of the shift register. The CLOCK
PERIOD is selectable from IllS to 333 SEC (outer
engravings). Note that the period is directly related
to GAUSSIAN NOISE BANDWIDTH, which is se­
. Iectable from 50kHz to .OOOI BHz (inner engravings).
02182-1
( 1 1 ) SEQUENCE LENGTH control. 18-way selector
which by altering the shift register feedback arrange­
ment� determines the numoer of hits (clock peri9ds)
In the pseudo·random sequences. Outer engravings
(n) indicate the number of register stages involved
In sequence generation, and the inner engravings
(N = 2n - 1 ) state the actual number of bits in the
sequence. N is selectable from l B to 1048575,
corresponding to values of n from 4 to 20.
(12) SEQUENCES PER G ATE INTE RVAL control.
4-way selector determines the duration of the gate
signal in terms of a number of sequences ( 1 , 2. 4 or
8).
(13) GATE lamp. Normally out, but lights ( uring a
gate interval.
GATE RESET control. Push-button which
initiates a gate signal.
(15) RESET control. Push-button which, when op­
erated, stops the shift register (as does the HOLD
control) and resets it (together with some other
circuits) to a pre·determined state.
(25) GATE R E LAY terminals. Changeover relay
mimics signal at GATE connector.
(26) CONTROL selector. Slide switch: when set
to R EMOTE disables the RUN, HOLD, R ESET and
GATE RESET controls on th:. front panel. Th�e
functions can then be remotely controlled via the
36-way CONTROL receptacle (27).

hibits the binary relay. when set to OFF, so pro­
longing the life of the relay contacts.
INT/EXT control. Slide switch: se­
lects the source of timing pulses for the shift re­
gister. When the switch Is set to I NT, the hp 3722A
is controlled by its internal clock (period from IllS
to 333 sec), the output from which is available at
the C LOCK connector (22). When the switch is set
to EXT the internal clock is disconnected and the
hp 3722A Is timed by an external device (frequency
up to lMHz) coupled to the CLOCK connector.
Figures 3-13 and 3·14 show clock Input and output
circuits.
trol is achieved by grounding the appropriate pin
( Figure 3-17). 18 pins, plus one common pin, are
used for remote signalling of the sequence length ' I
selected on the hp 3722A front panel. Each pin
(Figure 3-17) is related to a particular position of
the SEQUENCE LENGTH switch and, when the
switch is set to that position, is connected to the
common pin (the remaining 1 7 pins in th3 group
are open·circuit). One pin of the 36-way receptacle
is used for the 'inwJrt' input to the sequence shift
mechanism (Option 01 models only).
(24) GATE connector. Gate signal output: falls
from +1 2.BV to zero at start of gate interval, and
returns to + 1 2.5V at end (Figure 3-16).

in detail the circuits of individual assemblies. A sum·
mary of Hewlett·Packard logic terminology is given

4-5 TIMEBASE (CLOCK) GROUP. The internal
timebase of the 3722A comprises a 3MHz crystal·
controlled oscillator, a divide-by·three circuit and
a ' chain of nine standard decade dividers (of the
type used in Hewlett·Packard electronic counters).
Operation of the divide·by·three circuit Is basically
similar to that of the decade dividers - it is a
standard 'count of four' circuit modified, by feed·
back, such that the number of pulses counted per
completil cycle is reduced to three. The timebase
is so arranged that, as the C LOCK PERIOD switch
S l Is rotat�d, 3MHz and 1MHz signals ' (from the
oscillator and divide·by·three respectively) are app·
lied alternately to the divider chain. A second Wafer
of the switch selects tappings in the chain to give a
range of output frequencies from 1MHz to 0.003Hz
(period, t.T, from 1pS to 333 seconds). The selected
clock output is applied, via the INT/EXT switch
S13, to tn'! shift p'!ise generator, which supplies a
, trc>in of trigg�.. pulses (one per cycle of the clock)
to the shift register. With S 1 3 set to EXT, the shift
pulse ', generator is driven by an external timing
signal applied to the C LOCK connector.
"
4·6 'CONTROL LOGIC. Principal functions of the
control logic are the enabling and disabling of thE'
shift pulse generator. When tho HOLD buttcn is
operated, the control logic produces an inhibiting
signal which stops the shift pulse generator, and
02182·'
hence the shift register. No further shift pulses are
generated until the inhibit is removed, by operation
of the RUN button. When the RESET button is
operated, the conlfol logic generates a similar
inhibit signal and, in addition, applies a reset pulse
to the shift register. Again, the Instrument re·starts
only when the RUN button is operated. The third
function (GATE RESET) of the control logic is
described in Paragraph 4·42.
4·7 Each of the four 'push· button' functions can
be remotely controlled by a signal (contact closure
to ground� or suitable voltage applied) on the
appropriate pin of the 36·way CONTROL re·
ceptacle on the ,ear panel (details in Figure 3-17).
4·8 SH I FT REGISTER. The shift register is a chain
of 32 flip,flops (stages; four of which are contained
in each shift register assembly. These flip·flops,
which are of a type commonly encountered in
digital computers and data proceSSing systems, must
not be confused with the more familiar divide·by·
two flip·flop used in the decade divider ijssemblies
(A4, etc): the shift register flip·flop is not a divider,
it is an information store. Each stage of the shift
register can store one 'bit' of information ('1' or
'0'), i.e. it can be in one or other of two stable
states (Paragraph 4·60). The flip·flop is said to
contain '1' li in the set state, a:1d '0' if reset. The
length of time that a bit of Information remains In
a stage is equal to the time interval between two
successive clock, or shift, pulses: for this reason,
each shift register stage can be thought of as a delay
line in which the time delay between input and
output is equal to the clock period.

4-9 The shift register stages are connected in cas­
cade so that, . on receipt of shift pulses, the infor­
mation they contain is stepped progressively along
the chain (in this case, 'information' means the
pattern of ones and zeros in the register). This is
illustrated by Figure 4-1 , in which five stages of the
shift register are shown initially to give - quite
arbitrarily - th� output pattern 1 1 01 0. All preced­
ing:rtagesare assumed to be in the reset state (giving
'0' outputs).

stages 3 and 4, the outputs from which are pre­
cessed in an exclusive OR gate (otherwise known as:
module-two adder, half-adder, non-equivalence or
anti-coincidence gate). This gate, which gives a ' I '
output only when its two inputs are dissimilar, is
described by Table 4-1 .

ceding stage, before the shift pulse arrives_ I nform­
ation ('0' of 'I') contained in one stage is thus
transferred, by the shift pulse, to the next stage_
This has the effect of stepping the entire pattern
of ones and zeros progressively along the chain as though 00 a conveyor belt. Note that the se­
quence of ones and zeros observed at the l,"tput
from one stage is a delayed replica of that from the
preceding stage. The delay between the two adjacent
sequences is equal to one period (AT) of the clock:

4-1 1 SEQUENCE GENERATION. In the 3722A,
theshift register operates in a closed loop condition,
and the input to the first stage is supplied via a feed­
back patll , from later stages of the shift register.
Under these conditions, the closed loop system
generates a repeated series of identical sequences ­
known as 'maximum-length' or 'pseudo-random'
binary 5ellUenCes (p.r.b.s.). Figure 4-2 shows a
simple form of p.r.b.s. generator. I n this example,
only the first four of the 32 register stages are
actually involved in generation ,of the sequence.

arrangement of Figure 4-2 can easily be derived.

The modulo-two sum of the outputs from the last
two stages is '0' (this can be written 0 ® 0=0). At
the first shift 11ulse, the 'I' in the first stage is trans­
ferred to tli e second, and is replaced by the '0' in
the feedback line. THis gives the pattern:

Paragraphs 4· 1 5 to 4·18
Note that, with the exception of 0000, the register
generates the maximum number of ' I ' and '0'
combinations possible with four stages. The all·
zero condition cannot arise (if It were to occur, all
stages of the shift register would remain In the '0'
sta,te, and the output would thereafter be an infinite
sequence of zeros).
4·1 5 The above table shows that the pattern appear·
ing at the output from the first stage is exactly the
same as that from the second, the third and
the fourth (and so on throughout the 32 stages of
the register). Note that there is a delay of one
clock period between the pattern from one stage
and the pattern from the next. The digit sequenc:e
from any of the 32 stages is:
1
With five stages thp. maximum number of 'I' and
'0' comllinations is 32 but, as before, the all·zero
condition cannot occur. The resulting p.r.b.s. is
therefore 31 bits long.
.'
4· 1 7 T'le 'active' length of the shift register (i.e.
that part involved in sequence S'Jneration) is select·
able, fwm 4 to 20, by the SEQUENCE LENGTH
switch. Feedback is always taken from the last of
the active stages. and from one or more of the pre·
ceding stages. For the 1 27·bit sequence In the
3722A. for example. feedback is taken from stage 7
(7 is the 'n' number engraved on the front panel)
and also from stages 3, 4, 5. Where more than two
outputs are modulo·two added; extra exclusive O R
gates are used, as i n Figure 4·5.

The group of gates shown in Figure 4·5 gives a 'I'
output only when there is an odd number of ' I '
inputs. The overall truth table for the group is given
in Table 4·3.
4·18 Note that the number of bits, N, in pseudo·
random sequences generated by the 3722A is always
one less than the maximum number of ' 1 ' and '0'
combinations possible with the selected length of
register. Thus if n is the number of active stages,
N=2n - 1 . For a particular active langth of shift
register, there are many possible feedback com·
binations giving sequences of the same length but
of different form. The 3722A provides only one
feedback arrangement for each active length of
register. I f required, the feedback arrangements and hence the form of the sequences - can be
modified by re·wiring the SEQU ENCE LENGTH
switch. This should be undertaken with care, as the
GAUSSIAN output amplitude distribution can be
seriously affected by changes in the form of binary
sequence from the shift register.

4·20 Note that this Is an AND gate for '0' levels:
this may seem unusual, but It should be remembered
that the assignment of signal level to logic notation
Is quite arbitrary, and varies from point to point
through the system.
4·21 Clearly, the duration of the sync pulse Is �qual
to the Interval between shift pulses, and hence equal
to the selected clock period (at the next shift pulse,
the shift register output pattern changes - no longer
satisfying the AND functif'n). The number of inputs
to the sync gate Is controlled by the SEQUENCE

"
' Is generated by a gate which seeks the all·zero con·

excluding the first stage. Thus for the m·bit se·

driven Into the '0' state by a signal from the control

Ing reset - and possibly after switch·on (with the

by the gating arrangement shown In Figure "·6.
I ! all stages in the feedback system are In the '0'
condition, then the output from the sync gate will
be '0' (the 'sync' condition) : this, coupled with the
'0' from the first stage, gives '0' output from the
auto·start gate. The logic Inverter, which supplies
one input of the exclusive OR gate, turns this 'O'
into, a ' 1 ' level. The other Input of the gate is
supplied b y the feedback line which, if all stag::s are
in the '0' condition, must be at the '0' level. Since
its two inputs are dissimilar, the exclusive OR gate
gives a ' 1 ' output - which ensures that the first
stage of the regist�r will go into the ' 1 ' state when
the first shift pulse Is received.

4·23 BI NARY OUTPUT. In the standard version of
the 3722A (without Option 0 1 ) , the output from
the first stage of the shift register Is taken directly
to the output switch circuit. This produces an
accurately defined ± 1 0V verslon of the signal from
the first stage. The signal from the output switch Is
taken to the BI NARY (fixed output) connector,
the amplitude control (60on VARIABLE OUTPUT)
and a relay driver circuit, the output from which
controls the BI NARY R E LAY.

4·25 When Option 01 Is Included, the position of
the sync pulse Is shifted with respect to the sequence
for each of the seven shortest sequences (n=15 to
1 023). The necessary shift In rel&tive position Is
achlwed by generating the sync pulse at the same
point as before, and by delaying the actual BI NARY
output sequence, with respect to the pulse, by a
pre-�t amount (which Is specially selected for each
sequence).
-Figure 4 · 7 Sequence shift by combining outputs
4·26 As shown in r'aragraph 4·10, the sequence of
ones and zeros produced by one stage of the register
appears, delayed by one clock period, at the outpu t
from the next. The shift register itself thus generates
32 differently
delayed versions of the same sequence.

As a reSUlt, relative timing of sync pulse and BI N·
ARY output sequer.:e could be adjusted by up to
32 clock periods, simply by taking the output (I.e.
the output switch drive) from the appropriate stage.
The optimum shift for the longer sequences, how·
ever, Is greater thun 32 bits. To achieve Qreater
delays, use Is made of the 'shift and add' property
of pseudo·random sequences: this means that a
sequence added (modulo·two) to a delayed version
of Itseif produces yet another delayed version of
the original sequence, as in Figure 4· 7.

4·29 GAUSSIAN NOISE. In the 3722A , the Gauss·
lan multl·level noise signal Is generated by low·pass
filtering the binary output from the shift register.
Examples of this are shown In Figure 4·8, where a
pseudo·, andom binary signal Is applied In turn to
three low·pass RC filters, of diminishing cut·off
frequency. The first filter, having a time constant
equal to approximately one third of the clock fre·
quency (period 3.311S, frequency 300kHz), distorts
the edges of the waveform but leaves a stili re·
cognisable pattern. The third filter, however, has a
much longer time const"nt and gives a multi·level
output very similar In appearance to the Gaussian·
type waveform from the 3722A (oscilloscope
photograph '8' Table 3·1 ) : not only does this
filter convert from two·level to mul ti·level, It also
modifies the freque'1cy spectrum of the Slgr-ill, as
shown In Figure 4·9.
4·30 The filter In the 3722A is a digital device
which is not subject to the same limitations as the
conventional low·pass filter (in particular, the
3722A filter is required to yield a rectangular
spectrum of selectable cut·off frequency down to
0.00015Hz - not practicable with conventional
devices).

infinite, the feedback system is disconnected, and
the first stage of the register is controlled by a

random signal Is sampled by a level detector which
decides, on arrival of the shift pulse, whether a ' I '
or a '0' Is to be placed In the ilrst stage of the re·
glster. Since the random signal Is non'periodlc,
there Is no repeated pattern in the resulting series
of ones and zeros from the register.

Section IV
Paragraphs 4·31 to 4·34
4·31 Consider first a simple method of digitally con·
verting a binary signal ' into a multi·level waveform.
In Figure 4·10, two stages of a shift r�gister are
coupled to resistors of similar value, and the circuit
is so arranged that the current flowing through
each resistor depends upon the state ('0' or ' 1 ') of
its associated stage. I f, say, a stage in the ' 1 ' state
causes its load resistor to pass one unit of current,
then the possible combinations with two stages
are:( 1 ) No current (both stages in '0' state).
(2) One unit of current (either stage in ' 1 ' state).
(3) Two units of current (both stages in ' 1 ' state).
Hence the signal at the summing point can at any
given time have one of threo ,'alues, depending on
the combination of digits in :ne two stages. Figure
4·1(1 shows the sort of three·level signal which could
be produced by a two·stage device, assuming
arbitrary changes in digital patterr.. Note that, in
normal shift' register fashion, the pattern changes
only when a shift pulsc is received. Clearly, with a
larger number of 'bits' contributing to the output,
the number of possible signal levels is increased.
The device therefore acts as a flIter in that it
derives a multi·level waveform from a two·level
signal, as does the low·pass filter described above.

A train of pulses of width AT has a (sin xIx) shaped
spectrum with the first null occurring at the fre·
quency l/AT. Clearly, for a train of stretched
pulses as in Figure 4·1 1 , the frequency of the first
null is 1/1 OAT: in other words, the bandwidth of
the signal has been reduced by the factor 1 0.
4·33 I t follows that the shift register with equal
load resistors acts as a low·pass filter having a (sin
xIx) shaped characteristic. In the 3722A , however,
the requirement is for a Gaussian signal having a
rectangular spectrum: in other wor�s, the shift
register device must be modified in such a way that
it behaves as an ideal filter.
Figure 4 - 12 Pulse response of ideal low·pass filter
4·34 An ideal filter, when excited by 3 pulse input,
gives an output On the TIME domain) of (sin xIx)
form (Figure 4·12). If, therefore, the shift register
can be arranged to give a (sin xIx) shaped time
waveform for each ' I ' pulse anolled to the input,
then it must be acting as ar. ideal filter, with
rectangular frequency response. This is achieved by
choosing resistor values such that the current contri·

4·35 As shown In Figure 4·13, the (sin x/xl curve
Is IncoJ11 plete, and stops short at a point In the
second lobe on either side of the centre line: this Is
because of practical limitations on the size of shift
register. Note that the contribution to the signal
made by the first and last groups of seven resistors
Is required to be of the opposite polarity to that
made by resistors In the central group. This Is
arranged by supplying all resistors In the central
group with 'reset' outputs from the shift register,
and supplying those In the outer groups with 'set'
outputs (Paragraph 4·601. I t follows that a ' I ' start·
ing at .:lne end of the register and being conveyed to
the other, by a series of shift pulses, will generate
the waveform shown In Figure 4·1 4 : this is similar
to the, waveform produced by the digital filter when
In the test condition. With theSEOU ENCE LENGTH
switch S2 set to I N FI N ITE and the chassls·mounted
switch S 1 5 set to TEST, a single pulse recirculates
In the shift register, and a waveform like that shown
In Figure 4·14 can be observed at the digital filter
summing point (refer to Section VI I I , Digital Filter

4·36 The digital filter in the 3122A has the almost
rectangular frequency characteristic shown in Figure
4·15. Owing to the limited size of shift register,
, which results In truncation of the (sin x/x) curve.
the corner of the frequency characteristic is not
perfectly square. The high frequency comp onents
in the Gaussian , output spectrum are caused by
. abropt changes in output level as pulses pass down
the register, and are removed by analog filtering
(Paragraph 4·40).

4·37 The unique feature of this digital filter is that
the cut·off frequency automatically keeps in step
with clock· frequency: even at the lowest clock
frequencies. tre filter always has a flat response

and sharp cut·off. The direct relationship between
clock frequency and cut·off frequency follows from
the relationship between the (sin x/xl time function
and the corresponding frequency function. This
relationship Is shown In Figure 4·16: If the clock
frequency is increased then T decreases, and the
cut·off frequency rr/T increases.

4-40 ANALOG F I LTERING. In analog computing
applications, time derivatives (I.e. differentiated
versions) of signals occur frequently and. whenever
a signal has sharp edges, there is the danger that
darivatives could cause overload. In the case of a
stepped waveform, with Its very fast transit times.
, even the first time derivative would be a series of
very large amplitude spikes. For this reason, a second
order. analog filter Is Included In the 3722A to re­
move sharp edges from the digital filter output
waveform. As a result, neither the first nor the
second time derivatives of the waveform yield sharp
spikes. The p.d.f. for both derivatives Is reasonably
Gausslan (Section I l l , Figure 3-9).

Section I V
Pilragraphs 4·43 to 4·49
4-43 CIRCUIT DESCRIPTION
4·44 CONTROL LOGIC ASSEMBLY AI. The con·
trol logic assembly A l (Figures 4·18 and 8·7)
receives inputs from either the push·buttons '01') the
front panel or the 36·way CONTRO L receptacle on
the rear panel. Only one of these sources of control
signals may be used at any one time, and the CON·
TROL selector SI I (rear panel) must be set as
appropriate - LOCAL for push·button control or
R EMOTE for control signals via the 36·way re­
ceptacle (typically, the instrument is remote con·
trolled by nrounding the appropriate pin of the ,
CONTROL receptacle). The four function circuits
in A I are basically similar, each comprising an OR·
gate (AI R23+A I R24) and an ac coupled AND·gate
(A I C2+AICR2) similar to Ihose i n the shift register
assembly (Paragraph 4·6 1 ). The O R·gate, when one
of its inputs is grounded (via push·button or CON·
TROL receptachi ), primes the AND-gate to pass
the next negative-going signal from inverter A I QI
(which receives a synchronising signal from the
decade divider chain). The reset outputs (pins 4
and 8) are negative-gqing pulses of short duration:
,the gate reset is taken directly from AND·gate
AIC8+AICR6, but the shift register re&:!, wllich is
more heavily loaded, is arr.plified by A I Q4+A I Q5.
4·45 The run/ho�d mechanism includes a memory
element, flip·flop A1Q2+AIQ3. On receipt of a RUN
signal, OR-gate A I R23+A I R24 primes the dc input
of AND-gate A I C2+A I CR2. On the next falling
edge of the synchronising signal from AIQI, the
gate passes a negative-going pulse which switches
the flip·flop into the 'run' state (output at pin ID
falls from +I O,V to +3V). The flip·flop remains in
this state uritil re5o'tt by either HOLD or , RESET
signals.
4·46 3MHz CRYSTAL OSCI LLATOR ASSEMBLY
A2. The oscillll tor assembly (Figure 8·8) is a two­
section circuit comprising a 3MHz crystal·controlled
oscilla�or A2QI and a Schmiu trigger, A2Q2+A2Q3,
which ' produces a squared version of the 3MHz
signal suitable for application to either the divide­
by·three assembly, A3, or decade divider A4. Capa·
'
citor A2C3 allows frequency adjustr)1ent of approx i·
'
mately Q03%, this being'sufficient to accommodate
the known tolerance on 'as cut' crystal frequency,
and thus allow two or more 3722A noi!:<: generators
to be operated at the same frequency.
4·47 DIVIDE·BY·THREE ASSEMBLv A3. The
divide-by·three assembly (Figures 4·19 ,."d 8·10)
derives a IMHz signal from the 3MHz uscillator
output. The assembly comprises a conventional
flip-flop (stage B) and a binary stage (stage A)
similar to the typical decade divider stage shown
4·12
Model 3722A
in Figure 4·20. A binary stage is a special flip, flop
with commoned inputs arranged so that, on receipt
of a train of input pulses, it switches alternately
from one state to the other. The circuit of Figure
4·20 is a 'positive true' device, that is, only positive·
going input signals have any effect. A positive'going
pulse passed by the input capacitor turns off the
conducting transistor which, via the cross-coupling
components, turns off the other transistor. The
following pulse at the ir:put restores the device to
its original state, thus completing the cycle of op·
eration. Since one complete cycle requires two
input pulses, the binary stage can be said to divide
by two.
4·48 The binary stage. A, in the divide·by·three
assembly is a modification of the standard arrange­
ment - the left·hand input is supplied via a 'control
valve' (OR'gate A3CRI+A3CR2), which is turned on ,
only when the feedback signal from stage B is at
the low level (-22V). In tha waveforms of Figure
4·19. stages A and B are assumed initially tt) be in
the same state - outputs A and B at the high level
(zero volts). The first rising edge of the input signal
from A3Q I is applied to both sides of stage A direct to the right·hand side. and via A3CR 1+A3CR2
to the left. Since th� right·hand output, A, was
already at the high level, the right·hand input has
no effect : the left·hand input, however. causes the
device to flip to its other stable state - output A
low. The second rising edge of tile input signal
restores the binary to its origiloal state, where A
is at the high level : 10te that this time the signal
is effective at the right·hand input). The rising ed:"O
at A flips stage B. causing the feed back line to
switch to the high (zero volt) level : the zero·volt
feedback level clamps the output from O R'gate
A3CR 1+A3CR2, preventing the transmission of
pulses via Cl. and thus inhibiting the left·hanG input
of the binary. Since output A is already at the high
level. the right·hand input of the binary is also in·
effective. The third rising edge of the input signal
therefore dOllS not alfect the binary, but instead
flips stage B: when B flips, the feedback level lalls
to -22V. removing the inhibit and thus allowing
the cycle of operations to repeat.
4·49 DECADE DIVIDER ,ASSEMBLIES A4 THR·
OUGH A 12. Each decade divider as>;cmbly divides
by IC the frequency of its i nput signal. I n the
3722J. . nine decade divider assemblies are connected
in ca.>·� je. and their outputs are tapped by '1e
CLOCK PERIOD switch to provide a selection of
frequencies to drive the shift pulse generator.

where A13Ql conducts and A1 3Q2 is cut off.
Quiescent c.Jnditions are restored - again almost
instantaneously - by the next negative·going edge.
The circuit thus acts as a shaper capable of con·
verting almost any type of input signal (e.g. sinu·
soidal or triangular from an external generator)
into a rectangular waveform. After amplification in
A 1303 and A 1 304, the Schmitt output is taken, as
o timing signal, to the random noise sampler A30,
and also to the CLOCK connector (when S13 is set
to INT). AI3RI 9+AI3R20+AI3CR5 protect A1304
against damage arising frOI.1 signals applied acci·
dentally to the CLOCK connector. There is no in·
version between the input (A 1 3 pin 3 or pin 4) and
the main output at A 1 3(7) - positive'going input
gives positive'going output.

A 1 3R25 flows through the primary winding of
A 1 3Tl . When A 1 305 Is switched on (coincident
with a negative'going edge on A1301 base), the
rapid rise In collector voltage transmits a positive­
going pulse via A13C5 to the base of A1 305: this
pulse momentarily turns on A 1305, which in turn
cuts off A 1 306. Cutting off A 13 b6 is In effect
breaking the series circuit AI3T1+A13R25 between

rate of current decay in A13Tl primary, and hence
a large induced voltage tending to maintain the

approximately 50V amplitude across the primary
of A13Tl. and a negative'going IOY pulse is induced

A 1 3(9) is approximately lOOnS. The shift pulse,
which is applied simultaneously to all stages of the
'
shift register, is used also to generate inhibit signals
(A 1 3 pins 1 3 and 14) which disable the auto·start
logic during the Instant of change in the register.
4·58 The shift pulse generator is under the control
of the R U N/HOLD mechanism in the control logic
assembly (Paragraph 4·45). When ttie control logir,
is in the HO LD condition, the dc level at A 1 3( 1 )
is approximately +10V and A13CRl is biased off .
A 1 3CR2 conducts, and the resu lting voltage on
A 1 30 1 base is held positive with respect to the
emitter voltage. The transistor is thus held in the
conducting condition and cannot respond to the
input signal. When the control logic is switched into
the RUN condition, the level at A 13( 1 ) falls to
02182-1
approxima\�ly +3V . this l ime biasing off A13CR2:
the base , of I� 1 301 then assu� es the relatively
negative voltage set by the potential divider between
the +1 2.5V and -22V supply rails. I n the absence
of an Input signal, therefore, A 1 301 is cut off.

Figure 4·23.
4·60 Logic signal levels in the shift register are
nominally + 1 2V and zero volts. The shift register
logic is negative true; the 'true' condition is
represented by zero volts, Each flip-flop gives two
outputs, known as 'S' and 'R': when the flip·flop

S is true and output R is false. Output conditions

4·61 The two outputs from each stage are camected,
via AND gates, to the corresponding inputs of the
next. I nformation is transferred from one stage to
another only or receipt of a shift pulse, a negative­
going signal applied simultaneously to the ac
coupled inputs of all AND gates in the shift register.
Each AND gate comprises a resistor, diode and
capacitor arrangement as shown in Figure 4-24.
Note that the AND gate allows the shift pulse to
pass through only when it is enabled by zero volts
(true) on the dc coupled input. In this condition,
the junction of R and CR is held at approximately
zero volts, and the shift pulse passes via CR as a
negative-going spike superimposed on the junction
voltage. If, on the other hand, the dc coupled input
is at the false (+ 1 2V) level when the shift pulse
arrives, �h� junction voltage is high and the pulse
does not cause C R to conduct - hence no output
from the gate. Operation of the complete shift
register mechanism is illustrated by Figure 4-25, in
which the '0' held by one stage is shown to be
transferred, by the shift pulse, to the next.
4·62 DIGITA L F I LTER ASSEMBLY A 1 5 ETC.
r he complete digital filter comprises four similar
,assemblies, A 1 5. A l B, A21 arid A24 (Figure B-20
to B-26). Overall function of the filter group is
described in Paragraphs 4-31 to 4-39.
4·63 Basis of the filter assemblies is the clamp
circuit shown in Figure 4-26. The clamp circuits
are identical in fNery respect other than the value
of the weighting resistor, R5 - from one end of the
filter to the other, the 'weights' follow the approxi­
mate (sin x/x) curve of Figure 4-13. One end of the
weighting resistor is taken to the collector junction
021B2-1
in the clamp circuit, and the other to the filter
busbar, or summing point. which feeds the GAUSSIAN
output amplifier system. With the exception of
stages B and 25, each stage of the shift register is
associated with one particular clamp circuit. Stages
B and 25 do not drive clamp circuits, and therefore
make no contribution to the filter output (this is
equivalent to assigning zero weighting to the two
stages, which correspond to the zero crossing points
on the curve of Figure 4-13).
4-64 Depending upon the state of the associated
shift register stage, the collector junction in the
clamp circuit is held at either ground or +9V. At a
given time, therefore, the current contribution
made by a particular stage to the digital filter output
depends on:( 1 ) The state ('set' or 'reset') o f the stage.
(2) The weight assigned to the stage.
(3) The voltage at the filter summing point (this
in turn is dependent upon the contributions
made by all other stages) .
4·65 FEEDBACK LOGIC ASSEMBLY A27. The
feedback logic assembly (Figures 4-27 and B·2B)
contains three identical modulo·two adders of the
type described in Paragraph 4-09. The overall trulh
table for the assembly is given in Table 4·3.

functions of the auto·start assembly (Figures 4·28

....
(3) Amplification of the sync signal: amplifying

A
4·67 If all stages of the shift register are In the '0'
state, both the 'all·zeros' signal from the sync gate
and the output from the first stage of the register
must be at the '0' level. Since there Is no Inversion
(overall) In A28Ql and A28Q3, It follows that the
two active Inputs to OR·gate A28CR3+A28CR4 will
also be '0'. I nversion by A28Q4 gives a ' I ' Input to
the modulo·two adder A28Q5+A28Q6+A2807, the
other Input of which Is supplied by the feedback
logic. With all stages of the register In the '0' state,
this feedback signal must also be '0'. The modulo·
two adder thus receives dissimilar Inputs and, In
consequenc ', supplies a ' I ' signal to the first stage
of the shift register.

by grounding A28(15) via either C R I or C R2.

4·69 RANDOM NOISE GENERATOR ASSEMBLY
A29: The random noise generator assembly (Figure
8·32) uses as a noise source a transistor (A2901 )
biased in the base-emitter breakdown condition.
The output from 0 1 is amplified by A2902+A2906.
The output from the assembly is white noise ' of
approximately 1 0M Hz bandwidth and 5V peak·to­
paak amplitude.
, 4·70 RANDOM N O I S E SAMPLER ASSEMBLY
A30. When the SE�UENCE LENGTH switch is set
to INFI NITE, thE feedback logic (A27) is dis-
connected and the input to the first stage of the
shift register is provided by the random noise
sampler assembly (Figures 4·29 and 8·34). The
principal function of this assembly is to decide,
before arrival of each shift pulse, whether a '0' or a
' I ' is to be supplied to the register.
4·71 The requirement is for one sampling per clock
period and, wil�. clock frequencies as high as 1 MHz,
this allows only a very short time in whic tl the
sampling decision can be made. In the worst case
( 1 � " 1z clock), the time available for sampling is

Paragraphs 4·72 to 4·73
,
4·73 Pulses from the monostable alternately set and
reset the divide-by·two flip·flop A30Q4+A30Q5.
Since the clock interval (for a given setting of the
CLOCK P E R IOD switch) remains constant, the state '
in which the flip·flop remains at the end of the '
gating interval depends entirely on the number odd or even - of pulses received from the mono·
stable (with a 10MHz bandwidth noiw input, the
probability of either state is almost exactly 1/2). If
the divide-by·two flip,flop were connected directly
to the shift register, there would be the possibility
of assymmetrical loading on the flip,flop owing to
stray capacitance, etc: this could give rise to a pre­
dominance of 'ones' or 'zeros' in the B I NA R Y
output, that is, there would no longer b e a pro·
bability of 1/2. To prevent such one-way bias the
divide-by·two circuit is buffered locally by an extra
shift regl�ter stage A30Q6+A30Q7, the mechanism
of which is similar to that of a normal shift register
approximately 600nS (that being the longer of the
two events in the clock cycle). To avoid any signifi·
cant, correlation between the results of successive
samplings, a reasonable numbai of zero crossings of
the noise input (from A29) must occur during the
6oonS: the average numl::r of zero crossings per
second is related to bandwidth which, to guarantee
non-correlation, must in this case be around 1 0MHz.
4·72 Noise from A29 is squared by tunnel diode
A30CR 1 , and the resul t is gated with the inverted
clock waveform from A30Q2. The gating interval
starts immediately after the shift pulse, and ends
at the next positive-going transition of the clock
signal at A30 ( t ). The gate output drives monostable
A3OCR4+A30Q3, which generates constant·width
pulses (approximately lOOnS): the number of pulses
generated in a particular' gating interval depends on
the number of zero crossings, in that interval, of the
noise input.

stage (Paragraph 4·6 1 ) . The state . into which the
extra stage is 'frozen' depends on the state assumed
by the divide·by·two circuit at the end of the gate
interval. Note that the el'tra stage is strobed by the
negative-going edge of the clock signal, that is, at
the same time as the shift pulse is applied to the
shift register.
. 4·74 When the chassis-mounted switch S16 is set
to NORMAL, there is the possibility that noise
picked up by the switch and interconnecting wires
could be fed back into the sampler assembly. To
prevent the possible biasing effects of this noise,
the divide·by·two stage is effectively disconnected
from all external circuits during the gating interval.
The voltage at the junction of resistors A3OR24+
A3OR26 is determined by the clock input at A3O(l )
Which, during the gating interval, is at zero volts: in
consequence, diodes A3OCR6+A30CR9 are biased
off, and the circuit cannot be affected by noise on
pins A30(8) and A30(9). When S16 is set to TEST,
the 'extra' stage A3006+A3007 converts the shift
register from the normal open-ended arrangement
into a closed loop, which generates the recirculating
'1' used for checking the digital filter. The loop is
completed as follows:

The '1' is placed in the closed loop simply by

4'-76 OUTPUT SWITCH & R E FERENCE POWER '
. SUPPLY ASSEMBLIES A31, A32. The reference
power supply assem bly A32 ( Figures 4·30 and 8·37)
provides a stabilised +9V supply for the digital
filter, and a negative reference to which the digital
filter summing point is connected via R6. A32 also
contains part of the + l P', and -10V operational
amplifiers associated with ,he output switch. A3201
is a stable voltage' source supplying amplifier
A3202+A3204, the output from which (nominally
. +9V) is determined by A32 R9/A32R6. The negative
reference voltage is provided by amplifier A3203+
A3205tA3206+A3207, and is determined by the
ratio of A32R24+A32R25 to the parallel network
R7+A32R l Z+A3ZR 1 3+A32R 1 4... A3ZRZO. The re­
sistance of the parallel network (and hence the ne­
gative reference voltage) is variable, and depends on
OZ18Z·1
the setting of the SE�UENCE LENGTH switch as the switch is turned clockwise (from n=4), the
resistance is progressively reduced by a shorting
link (S2JF). The resulting shift in reference voltage
compensates for de bias, in the GAUSSIAN output,
arising from a predominance of 'ones' in the shorter
binary sequences (the difference between the
numbers of 'ones' and 'zeros' is not significant in
sequences longer than N=1023: hence no further
correction).
4-76 The +1 OV level is provided by operational
amplifier A3Z08+A32010+A3Z01 2+A31 01 , the
output from which is determined by A31 R18/
A31 R8+A31 R9. A31 R9 allows adjustment of the
+ 1 0V level. Principal components of the switching
mechanism are ihd inverter A31 02 (not shown in
Figure 4·30) and switching transistors A31 04,
A31 05. A3106, A3107. When the input at A31 (7)
switches to the low level (zero volts), A31 OZ con·
ducts and switches on A31 06, thus connecting the
B I NA R Y output A31(6) to the +IOV rail. When
A31 06 switches off (at the next transition of the
input signal), A3107 switches on, connecting the
output to the -10V rail (established by A31 R 19/
A31 R I O+A3 1 R l l in conjunction with amplifier
A3209+A3Z01 1+A3Z013+A3103). When A3106
switches off, the feedback loop via A31 R 1 8 is
broken, and the +IOV amplifier would saturate if
no alternative feedback path were provided (if
saturation were to occur, the amplifier recovery
time would be unacceptably long, and high fre­
quency operation of the output switch would be
unsatisfactory). The alternative feedback path is
via A31 R l 3, which is switched into circuit by
A31 05 at the instant A3106 ceases to conduct.
A31 R 1 3 is adjusted so that the voltage at test point
1 remains constant when the transition occurs. This
mechanism, which ensures that conditions in the
amplifier remain undisturbed, makes possible very
rapid. switching between output levels, with very
little distortion of waveform !transition time less
than lOOnS). The -10V amplifier is similarly pro­
tected by A31 R l7, which is switched in by A31 05.

4·83 GATE & SYNC OUTPUT ASSEMBLY A41 .
The gate and sync output assembly (Figures 4·35
. and 8·51 ) pRrforms the following main functions:
( 1 ) Amplification of the sync signal.
(2) Amplification of the binary relay drive signal.
(3) Generation of the gate signe...
4-26
The sync signal is amplified and invllrted by A41 0 1 .
which feeds both the sequence counter A39 and the
SYNC output connector J l 0. A4101 also supplies
a strobe signal to the ac coupled gates associated
with the gate latch circuit A41 03+A41 04. A4107,
the binary relay driver, is supplied with a binary
signal taken from the first stage of the shift register
(or from assembly A40 in the Option 01 version)
via a buffr.. diode A31 C R l in the output switch
assembly ( A3 1 C R l prevents loading of the shift
register stage).
4·84 Operation of the gate latch circuit is illustrated
by the waveforms of Figure 4·35. The flip· flop is
assumed to be initially in the reset ('gate off')
state. When the GATE RESET button is operated,
the sequence counter is reset (Paragraph 4·81 ), and
the resulting zero volt signal on the wiper of S4AF
primes AND·gate A41C3+A41CR6 to pass the next
sync pLllse (a negative-going signal) from A41 0 1 :
this pulse sets the flip· flop to give a high output
(+12V, waveform 4) and hence a low oulput (zero
volts) at the GATE connector J 1 1 . This transition
marks the start of the gate interval.
4·85 After counting the demanderJ number of sync
pulses (Figure 4·3f :�ows the case where the gate
switch S4 is set to '4'), the sequence counter is
inhibited and the resulting high level (+12V) signal
on the wiper of S4AF switches inverter 1\4102 to
give a zero volt output: this prime� AND·gate
A41C2+A41CR4 to pass the next sync "lllse from
"";41 0 1 . On receipt of this pulse, the flip·flop is
reset and the GATE signal at J 1 1 switche.- to the
high level, thus marking the cnd of the gate in·
terval. Amplifier/inverter A4106 drives both the
GATE lamp (front panel) and gate relay in A42.
Note the provision of a gate reset input t,l flip,
flop A41 Q3+A41 04. Under normal circumstances
this is not required, as the flip',flop is automatically
reset at the end of the gate cycle: it is significant
only if the gate is cancelled - by operation of the
GATE RESET button - during the actual gate
interval.
4·86 RELAY ASSEMBLY A42. The relay assembly
(Figure 8·51 ) contains two similar changeover·type
reed relays. The changeover contacts are brought
out to two sets of terminal posts on the rear panel.
A42K l , the binary relay, is de-energised when the
main BINARY output is at +10V, and energised
when the BINARY output is at -10V. A42K2, the
gate relay, i� normally de-energised, and is energised
only during a gate interval.

details, refer to Figure 8·56. The ac supply, of line
voltage 1 15V or 230V, is connected through fuse

O F LOGIC TERMINOLOGY
4·91 LOGIC SIGNAL LEVELS, In a digital system,
information is conveyed by signals .....hich can have
only two possible levels. In logic notation, these
levels are designated '1' and '0'. The ' 1 ' level is
generally taken to mean yes, enable, true: hence,
'0' means no, disable, false. When relating logic to
hardware, the ' 1 ' and '0' levels nllJSt be carefully
defined - in' a particular part of a system, the '1'
' could be represented by the more positive of the
two signal leVels but equally, in another part of the
system; it could be represented by the more
negative. With the hp notation, the symbol for
each logic element is assigned'(+) or (-) to indicate
which of the two signal ' levels the element re­
cogni!.es as 'true'. '
4·92 TRUTH TABLE. Using the ',. and '(1 notation,
a truth table completely describes the function of
a logic element. For examp,le, AND gate having
inruts A. B and an output C, is described in the
following way:

An AND gate may have more than two inputs: for
a multiplef input AND gate to give a true output,
'
a/1 inputs must be true.

gate is:

Gate gives a 'true' output only
when both A and B are true.
4·93 SYMBOLS
4·94 AND GATE. The symbol for a two-input
AND gate is:
0
C will also be e t the relatively pOSitive level. If,
for example, the two possible signal levels are + 12V
and zero volts, the truth table could be re·written:
zero volts == '0' false
+ 1 2V == '1' true
l e
The truth ta�:e for this gate is:

An OR gate may have more than two inputs: a
multiple-Input OR gate gives a true output if one,
or more, of the inputs is true.
This is simply a conventional AND gate (Paragraph
4·94) followed by an inverter which changes true to
false ( l' to '0') and vice versa. The truth table for
AND gate plus inverter is:

4·98 AMPLIFIERS. The symbol for an amplifier is:
4·96 AC COUPLING. AC coupling is indicated by
an arrow:
•
--t
AC coupling is commonly used in logic elements to
which a timin9, or strobe, signal is applied. Only
abrupt level changes at the ac coupled input affect
the element. ;The direction of level change is also
important: a positive true gate, for example, re­
sponds only to abrupt positive-going signals at the
ac. coupled input (changes in the opposite direction
have no significant effect).

This device has two stable states:
'SET' C true, 0 false
'RESET' 0 true, C false
The flip-flop can change state only on receipt of a
true signal appiied to the appropriate input: for
example, a flip-flop in the reset state is switched to
the set state by a true signal on input A. The signal
levp.1 defined as true for a particular flip-flop is
defined by (+) or H near the flip-flop symbol:

PRINTED CIRCUIT COMPONENT
REPLACEMENT
5-9 Component lead holes in the Model 3722A
circuit boards have plated walls to ensurE' good
electrical .contact between conductors on opposite
sides of the board. To prevent damage to this
plating and to the replacement component, apply
heat sparingly .and work carefully. The following
replacement procedure is recommended:
� , '
,
(a)
Remo"Je the defective component by first cut­
ting it free from its connecting leads, and then
melting solder to remove the bits of wire from
the holes.
(b) Melt solder in the component lead holes. Use
a clean, dry soldering iron to remove excess
solder. Clean holes with a toothpick or wooden
splinter: do NOT use a metal tool for cleaning.
as this may damage the through-hole plating.
(c) After bending the leads of the replacement
component to the correct shape, insert them
into the appropriate lead holes in the board .
Using heat and solder sparingly, solder the leads
in place. Heat may be applied to either side of
the board. A heat sink (longnose plier�, com­
mercial heat-sink tweezers. etc.) should be used
when replacing transistors and diodes, in order
to prevent cor duction of excessive heat from
the soldering iron to the component.
Id) Through·hole plating breaks are indicated by
lifting of the round conduct,or pads on either
side of the board. To . repair breaks, press the
conductor pads against the board and solder
the replacement component lead to the con­
ductor pad on 'both sides of the board.
NOTE
Special care must be taken when servicing
the following assemblies:A29 Random noise generator

Comment
Amplitude of the binary output is not easily measurable at frequencies greater than can be
accommodated by a digital ,voi tmeter (DIfM). Typica l ly, digital voltmeters can reliably sample
discrete voltage levels when the rate of switching between levels does not exceed, say, 2 or 3 per
second. In this performance check, ; the digital voltmeter is used to verify the binary output
amplitude at all cle �k frequencies less than and including 1 Hz (clock periods of 1 sec and greater).
The amplitude at frequencies greater than 1 Hz is checked by the visual comparison technique
described below.

6)
Repeat the observation for a l l other CLOCK PER IOD switch settings. There should be . no
detectable change in trace separation for clock periods down to, and including, 333/15
Some reduction in separation may be observed as the clock period is reduced beyond
333/1S. This reduction should not exceed 4% overall (2% shift each trace) for periods
between 1 00/lS and 3.33/1S inclusive, and 8% overall at the I/1S setting.

Procedure
1)
With the set·up described above, free-run the scope and observe the horizontal traces
produced by the binary output wi,h clock period I/1S. Detach the 1 k!l load from the
BINARY connector. Adjust the oscilloscope sensitivity to place the traces exactly I Dem

Couple the load to the BINARY connector and check that the separation does not de­
crease by more than 1%, implying an output impedance of less than IOn (this is the
.
'wor�t case' test for the range of clock periods loo/lS to I/1S).
3)
The output impedance for the range of clock periods 3331'S upwards is verified by a dc
level check. Press the RESET button and measure the +10V level with and without the
l kn lOad. The level change should not exceed 0.05V = 0.5%, implying an output im'

Comment
In thp. ba�ic performance check, two techniques are used tl) verify rms amplitude of the Gaussian
output: these are ( 1 ) direct measurement using an rms voltmeter, this being possible only at the
higher clock frequencies, and (2) sampling (with .. I)VM) the various voltage levels generated in a
complete sequence, followed by calculation of rms amplitude. This second method is limited by
the sampling rate of the DVM and, typically, is not suitable for clock frequencies greater' than
1 Hz. There is no straightforward technique of measuring the rms amplitude in the middle fre­
quency range (333mS ;;. clock period ;;. 333pS) ' but for most purposes it can be assumed that,
if the amplitude is within specifications at the upper and lower frequencies, then the middle fre­
quency performance is satisfactory. On occasion, however, it is essen tial to measure the amplitude
of the mid-band frequencies. and for this purpose, a method using a voltage-to-frequency converter
and an electronic counter is described below.

Procedure
for rnid·band frtlquency measurement
This procedure is in two parts:-
\\
(a)
Measurement of form factor c' the 1 023·bit Gaussian signal. This measurement is made
at a clock frequency which allows simultaneous readings of both rms amplitude (with
3400A ) and mean rectified amplitude iwith 3440A ) .
(b )
Measuremen,t of the mean rectified amplitude of the 1 023-bit Gaussian signal. Mean
rectified amplitude of the signal is given by integration over a known period (at least
1 023 x clock period in use) of the output from a voltage-to-frequem:y converter driven
by the Gaussian signal. Division of the result by the integration time gives the mean
, rectified amplitude, which is multiplied by the form fC'Ctor to give rms amplitude.

readmg, which should be in the region of 2.fIV, is divided by 1 . 1 1 for conversion to mean
rectified amplitude. (Since the 3440A reads rms amplitude of a sine wave input, the
indicated amplitude is converted to mean rectified amplitude when divided by the torm
factor of a sine wave). Mean rectified amplitude = 2.8/1. 1 1 .
Form factor is the ratio of rms amplitude to mean rec:ified amplitude, and for this
Gaussian signal is approximately equal to 3. 16 x 1 . 1 1/2.8 :':: 1 .24 .

accuracy of absolute measurements made by this process depends on attenuator preci�ion
and the setting'u P of the 2212A V FC.

Set the 3722A controls as follows:

Starting from zero, wind the 302A F R E QU ENCY dial to around 1 .9kHz and, with the
F I N E control, slowly adjust the dial until the meter shows a reading. Set the MODE
S ELECTOR toAFC. Allow the wave analyser to lock in and set the REFERENCE ADJUST
control to give a meter reading of exactly OdB. This is the reference against which all other
harmonics will be compared: the meter indication provides a useful double-check in
conjunction with DVM reading.
Print·out the DVM reading.
Tune the 302A to the next harmonic (2.9 1 4kHzl and again print the DVM reading.

Calculation
The DVM reads the rms amplitude of the restored frequency output
from the wave analyser_ I f the voltage reading for the fundamental
is x volts rms, and that for a particular harmonic is y volts rms, then
the power (ill dBI of the harmonic, relative to the fundamental, is:

( 1 ) Connect a dc null voltmeter, model 419A,
to the GAUSSIAN (fixed) output. Set
thl! voltmeter RANGE switch to 300mV.
Depress the VM button.
(2) Set the 3722A controls as follows:
(5) Connect an oscilloscope to the GAUSS·
IAN (fixed) output.
(6) Set the oscilloscope con'rcls as follows:
SENSITIVITY

EXT (from channel B
of 3300A )

(7) Adjust the 3300A channel A amplitude
for 5cm display (excluding overshoot),
then set sweep time to 2/1S/CM and ob·
serve leading edge of waveform. Ampli·
tu de of the overshoot should be between
0.45 and 0.55cm (9 to 1 1% overshoot): if
necessary, adjust A34C 1 6 to achieve this.
(B)
Repeat with CLOCK PE R IOD switch set
to 1 0/lS, Again, the overshoot on the 5cm
waveform shoulci be 0.45 to 0.55cm: if
necessary, adju�, A34C1 4 to achieve this.
SEQUENCE LENGTH to 2047
CLOCK PE R I OD to 10/lS
(3) Set the GAUSSIAN ZERO control (front
panel) to the mid·position (note the meter
reading at the fully cw and ccw settings,
then set the control to give a met�r read·
ing m idway between the two). Set both
A32R 1 3 and A32R25 to their mid·
positions.
(4) Adjust A32R 13 (1 Okn) to give null read·
ing on the meter.
(5) Set the SEQUENCE L':NGTH switch to
1 5 and note the change in meter reading.
If the meter reading changes by more
than 3mV, the de offset voltage must be
adjusted using A32R25 ( l k!2). The pro·
cedure for this is as follows:
Make a very small adjustment to
A32R25, remembering the direction
of rotation.

been established. the procedure is

(2) Connect the rms vol tmeter, model 3400A
to the GAUSSIAN (fixed) output. The
meter reading should be 3. 1 6V rms (full
scale on the 3V range): if necessary, adjust
A33R 1 .
(3) Remove the rms vol tmeter and connect
in its place a DVM.

(4) Set theCLOCK PERIOD switch to J33pS
and operate the RESET button. The DVM
reading should be 9.96V ± 20mV.
(5) Set the CLOCK PERIOD switch to l mS.
The DVM reading should remain the
same: if necessary, adjust A33R3 to
achieve this.
(6) Set the CLOCK PERIOD switch to
3.33mS. Again, the DVM reading should
be as before: if necessary, adjust A33R5
to achieve this.

SEC"rlON VII
OPTION 01
Sequence sftift for zl1ro time moment
7·1 INTRODUCTION
7·2 Time averages taken over one period of a
pseudo·random sequence are normally independent
of the point In time at which the averaging starts.
However, when the test signal is contaminated by
background disturbances such as steady drift - as
occurs in many practical systems - the re.<\1lt of
the averaging measurement can be in error. I n such
cases, the magnitude and sign of t\1e error depend
critically or. the starting point of the averaging
process. In Option 01 versions of the hp 3722A,
an optimum starting point (identified by the sync
pulse) has been chosen for each of the seven short·
est sequences (N = 1 5 to N = 1 023). This optirni·
sation Is such that the first tirr.e rnoment of the
pseudo· random binary sequence, with respect to
the sync pulse, is zero.
7·3
,
first modulo·two adder passes without r,\odification
through the second. If pin 21 is grounded, however,
the secnnd adder receives in effect a permanent ' I '
input 'lVhich inverts the binary waveform. A40Q8
+Q9 'ls a conventional flip·flop of the type used in
the shift register (Paragraphs 4·59 to 4·61 ) . The out·
put from the fIIp·flop is a delayed, inverted version
'
of that from the second module-two adder. I
7·6 Pairs of l'Ijlit register outputs selected by the
SEQUENCE LENGTH switch are as follows (refer
'
to block diagram, Figure 8·5) :·

7·4 Logic diagram and typical waveforms are ('i)/en
in Figure 7·1 . For circuit details, refer to Figure 7·4.
General information on the technique of sequence
shifting used in the hp 3722A is given in Paragraphs
'
4·24 to 4·27.
7·5 The two main inputs to the assembly, at
A40(1 4) and A4Q(5), are a sel;cted pair of binary
signals from the shi It register: selection is perforined
by wafers S2HF and S2JR of the SEQUENCE
LENGTH switch. A40Q i+Q2+Q3 generate the
module-two sum of the input pir, and sup�.iY the
result to a second module-two adder, A40Q4+Q5+
Q6. The other input of the second adder is taken
from the CONTROL receptacle on the rear panel:

7·7 CONVERSION TO OPl'lON 01
"/·8 To convert a standard hp 3722A instrument
into an Option
01 version, proceed as follows:·
,
( 1 ) Remove the wire link betwe�n pins 1 and <I of
socket XA40.
. (2) Insert into socket XA40 a Sequence Advance
Assembly, hp part number 03722·739.
(3) Check operation of the converted in�trument '
as detailed in Figure 7·2.

SERVICE NOTE
Digital filter check
(Applies to A 1 5, A 1 8, A21 & A24)
Procedure
Perform the digital fil ter functional check detailed
in Table 5·8. Extreme faults In the filter will be
immediately obvious - for example, the photograph
right shows the waveform obtained with resistor
R 1 5 in A21 open·clrcult. Isolate the fault by refer­
ence to the annolated waveform on this page. Note
that failure of a clamp circuit can cause the same
distortion of the test waveform as a resistor fault.
Each clamp circuit comprises two transistors sit­
uated, physically, near opposite ends of the asso·
ciated precision resistor - for example, resistor
A 1 5R 1 5 located between the transistors of Itsclamp
circuit, A 1 505 + A 1 506.
Faulty test waveform

monostable output pulses at A30Q3 collector
is reasonably constant. If the pulse duration
tends to track the period of the input signal,
it may be that the monostable is being forced
by an over-large input. Re-check after atten­
uating the signal generator output to the point
where the monostable just triggers regularly.

NOTE
,
With a true random drive from the noise sampler,
there is a 50-50 probability of the output from the
first stage of the shift register being at either the
high or low levels in any clock period. Hence, the
mean crossing ratp of the BI NARY output - with
I MHz clock - must be 500kHz. Two zero crossings
(one positive-going and one negative-going) are
The monostable operates only when the equivalent to one cycle of a periodic signal - so the

Blurred patches signify free-ruming divide­
by-two stage. At end of gating interval,
thedivide-by-two stage stops (signified by
the clear patches occurring once in each
clock period). The divide-by-two stage
should show no preference for either high
or low levels - hence the even intensity
of upper and lower traces.

SERVICE NOTE
Output amplifier (1) A35
ChfICking amplifier input offset and replacement
Value
After any servicing of amplifier assembly ,0..35, the
input offset should be checked as follows:
( 1 ) Connect to the 3722A GAUSSI<\N output a
DVM fitted with a high'gain auto range plug-in
(e.g. hp 3440A + hp 3445A ).
(2) Set the 3722A CLOCK PERIOD switch to
333j.1S and operate the HOLD button.
(3) Connect a shorting link between pin 4 of
socket XA24 and ground. The DVM reading
I
should be between ± lmV.
(4) Check that for clock periods 1 mS and 3.33mS
the DVM reading does not exceed ± 2mV.
If the DVM reading exceeds the stated limits, R 1 9
must b e replaced. The value of R 1 9 should be
increased if the DVM reading is positive, and vice
versa. A range of typical values is given opposite
(all resistors are MET OX, 5%, 1/4W).

COMMENT
EQUIPMENT
REQUIRED
One of the problem. of fault finding In a feedback ",.tem I. that a malfunction In one part of the
circuit Is propagated through the rest of the system. It is therefore necessary to break the loop at
some convenient point before attempting to find the source of trouble. However. bree!dng the feed·
back loop around a de amplifier usually gives rise to abnormal circuit conditions. since the feedback
also defines quiescent de conditions. Hence the unorthodox approach necessary when troubleshooting
the Gausslan output amplifier system.
