SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation and maintenance of this
instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture, and intended use of the instruments. Boonton Electronics assumes no liability for the
customer's failure to comply with these requirements.
THE INSTRUMENT MUST BE GROUNDED.
To minimize shock hazard the instrument chassis and cabinet must be connected to an electrical ground. The instrument
is equipped with a three conductor, three prong AC power cable. The power cable must either be plugged into an approved
three-contact electrical outlet or used with a three-contact to a two-contact adapter with the (green) grounding wire firmly
connected to an electrical ground at the power outlet.
DO NOT OPERATE THE INSTRUMENT IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made
by qualified maintenance personnel. Do not replace components with the power cable connected. Under certain conditions
dangerous voltages may exist even though the power cable was removed; therefore, always disconnect power and
discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is
present.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Do not install substitute parts of perform any unauthorized modification of the instrument. Return the instrument to
Boonton Electronics for repair to ensure that the safety features are maintained.
This safety requirement symbol has been adopted by the International Electrotechnical
Commission, Document 66 (Central Office) 3, Paragraph 5.3, which directs that an
instrument be so labeled if, for the correct use of the instrument, it is necessary to refer
to the instruction manual. In this case it is recommended that reference be made to the
instruction manual when connecting the instrument to the proper power source. Verify
that the correct fuse is installed for the power available, and that the switch on the rear
panel is set to the applicable operating voltage.
CAUTION
WARNING
The CAUTION sign denotes a hazard. It calls attention to an operation procedure,
practice, or the like, which, if not correctly performed or adhered to, could result in
damage to or destruction of part or all of the equipment. Do not proceed beyond a
CAUTION sign until the indicated conditions are fully understood and met.
The WARNING sign denotes a hazard. It calls attention to an operation procedure.,
practice, or the like, which, if not correctly performed or adhered to, could result in
injury of loss of life. Do not proceed beyond a warning sign until the indicated conditions
are fully understood and met.
This SAFETY REQUIREMENT symbol has been adopted by the International
Electrotechnical Commission, document 66 (Central Office)3, Paragraph 5.3 which
indicates hazardous voltage may be present in the vicinity of the marking.

The Model 92EA is a solid awe, semitNc, accuN11e, a.ad
"1l1dily constru.clcd llF Millivoltmeter I.hat is olw1ckrizcd
by high input impcdanoc, cxcdlcnl 5tability, and low ooi.sc.

Frequency RMSC Provides ¥Oh.age mcasumnco~ O\'Ct
the fn,quency range of 10 Uii lo U GH.z and 10 H.t to 100
MHz with the · 16 Option. Relative accuracyatio.<: 1.2 GH.z
is typically +/· 05 dB. RclMivc accuracy refers to tho dif.

~a 50 m V lipal, al thal aame frequency, will be indicated
as 10 mV, within about 05 dB (5.9%).
YoHnerRnga s Tht:vollngcrangei$200uV103V(300

demodulator is <IID=by a 94 Ht.demodulator driwe signlll,
which ii~ with tbe94 H.tchopperdriweQg!W. A
1yochrocous, wnpliag type demodulator circuit is used, ,.ith
the wnplc being tllCD II I point well ~ from tbe
chopper lwitching poiDu. ~ demodulator is folloW<:d by
lhe high input impedance buffer A2U26c to reduce loading
of lhc lilllllpfing capacitor A2Cl6 10 negligible proportioas.
Output DC is supplied to A2U2Ac in the &haping scaiott.
4·11. DRIVER CIRCUITS.
Chopper and demodulator driwe gjpll4 are derived from a
752 Hz signJiJ supplied Crom the dock circuiL A2Ql sbifu
1bcdock voltage from the zero to plus fM>YOlt ~(used by
the wpiag c:ircu.itry), to 1 +s and ·S volt fe\ocl used by the
cboppa c:ircu.itry. Flif>"'Dops A2Ul4a, A2Ul4b, A2Ul61
and A2U16b dMde down the 7$2 Hz &ignaJ 10 94 H2, and
gates A2Ul3a. A2Ul3b and A2Ul3e shape the 94 Hz
demodulator iignaJ. F"igure 4-3 ohows lhc derivation of I.be
chopper and dcmodu!Jltor drive signals from the752 Hz clod<
1ignal.
4-.18. CLOCK CIRCUITS.
Refer 10 F"ogure 4-5. A crystal a1111tollcd ooci!IAtor (A2Ul9a.
b, c and crystal Vl), provides 96 kfu clock pulsc.s. Th.is 96
kfu 1quarc wave is frequency dlvidcd in the binary counter
A2U:W to produce dock~ for both tho analog and the
ohapiag circuitry.
4-19. RANGING AND PROGRAMMING CIRCUITS.
Refer 10 rogun> 4-4. Rangiag of the imlnlmc:Al is pcdormcd
manu.tDy by means of the eight puohbuuon switches on the
front panel When a range is selected, one scction of AlS2
'short" to ground inputs to the rongc encoder. The range
encoder compri.scsA2UJ.Sa, A2U15b, and A2U17, and will
S""trele a binary range code on lines RO, RI and R2. This
raagc code ii used by bc&h the amplifier circuitry and lhc
ohaping circuitry to sclccl lhc appropriate sqpw processing
"-10. Remoie programming Is accompllshed by skrdt.aneOUSly sho<ling to coc1•1100 the Manual Dtsable ard
Ille appropriate range lines on the card edge comect:or
local.e d at the rear of the instrumenl $honing the
Manual Olsable fine turns oil A202. causing !he latter to
disconnect the front panel swttchos. Shorting the
Manuel Disable line also enables buffer A2U1S. allowing
b to transmit ranging lnlormallon from the card edge
