IMPORTANT NOTICE
After turn on, the synthesizer requires one hour of warm up
to assure stable operation. Error codes that are displayed
during this hour may not be the result of actual failures and
should be rechecked at warm up completion by running
self test.

SECTION I
GENERAL INFORMATION
1-1 SCOPE OF THE MANUAL
This manual provides general, installation, and op-
eration information for all models in the Series
67XXB Swept Frequency Synthesizer family.
1-2 INTRODUCTION
Section I provides information about the equipment
identification number, performance specifications,
options, and related manuals.
1-3 IDENTIFICATION NUMBER
All WILTRON instruments are assigned a unique
six-digit ID number, such as “405001.” Each 67XXB
has two ID numbers assigned, one for the basic
frame and one for the RF deck. The ID number for
the RF deck is affixed to the outside of the rear
panel, while that for the basic frame is affixed to
chassis floor, below the swing-out RF deck. The RF
deck ID number, on the outside, is the primary
number. Please use it when ordering parts or corre-
sponding with the Customer Service department.
1-4 RELATED MANUALS
This is one of a three manual set that consists of an
Operating Manual (OM), a Test and Calibration
Manual (T&C), and a Maintenance Manual (MM).
The OM and MM provide coverage for all models in
the 67XXB series. Conversely, the T&Cs contain
model-dependent information. Because of this
model dependency there are nineteen different
T&Cs—one for each frequency model.
Maintenance Manual (MM). The MM supplies
service information (circuit descriptions, trou-
bleshooting data, schematics, and block diagrams)
and parts lists for all 67XXB models. The WILTRON
part number for the MM is 10370-10242.
Test and Calibration Manual (T&C). The T&C
provides performance verification test procedures,
calibration and adjustment procedures, and test re-
cords for a specific 67XXB model. The WILTRON
part numbers for all T&Cs are listed in Table 1-1.
1-5 DESCRIPTION
The Series 67XXB Swept Frequency Synthesizers
are microprocessor-based, GPIB, synthesized signal
sources that generate swept and CW frequencies
from 10 MHz to 60 GHz. The series, which will
expand as additional frequency ranges are added,
presently consists of 29 models covering a variety of
frequency and power ranges. Table 1-2 shows a list-
ing of all of the present models, their frequency
range, and their output power level.

1-6 OPTIONS
Option 1, Rack Mount. A kit is available contain-
ing a set of track slides (90°tilt capability), mount-
ing ears, and front panel handles to let the instru-
ment be mounted in a standard 19-inch equipment
rack.
Option 2, Attenuator. Adds 110 dB step attenu-
ator to increase the RF output range.
Option 2A: For models with an upper frequency
limit of ≤20 GHz. Reduces rated power by 1.5 dB.
Option 2B: For models with an upper frequency
limit of 26.5 GHz. Reduces rated power by
2.0 dB.
Option 2C: For models with an upper frequency
limit of 40 GHz. Reduces rated power by 3.0 dB.
Option 9K, Rear Panel RF Output. Adds a rear
panel K Connector®RF output. Deletes the front
panel RF output connector. Rated output power,
flatness, and SWR are slightly degraded.
Option 10, Auxiliary Rear Panel RF Output.
Adds a rear panel K Connector®RF output. The
front panel RF output connector is retained. Rated
output power, flatness, and SWR are slightly de-
graded.
Option 14, Wiltron 360 VNA Compatibility.
Modifies the rack mounting hardware to mate the
unit in a Wiltron 360 VNA console.
1-7 PERFORMANCE SPECIFICATIONS
Table 1-3, beginning on page 1-5, lists the perform-
ance specifications for the 67XXB series synthesiz-
ers.

tion of the error.

tect confidential test parameters.

step size of which is variable via the keypad.
Controlled parameters are frequency, power level,
sweep speed, dwell time, pulse width, pulse repeti-

Entry is terminated by pressing appropriate unit key
(i.e., GHz, MHz, dBm, ms, %, etc.). Values of each
are displayed on LCD readout.

2-1 INTRODUCTION
This section provides information on initial inspec-
tion, preparation for use, and General Purpose In-
terface Bus (GPIB) interconnections. It also in-
cludes reshipment and storage information.
2-2 INITIAL INSPECTION
Inspect the shipping container for damage. If the
container or cushioning material is damaged, retain
until the contents of the shipment have been
checked against the packing list and the instrument
has been checked for mechanical and electrical op-
eration.
If the synthesizer is damaged mechanically, notify
your local sales representative or WILTRON Cus-
tomer Service. If either the shipping container is
damaged or the cushioning material shows signs of
stress, notify the carrier as well as WILTRON. Keep
the shipping materials for the carrier’s inspection.
2-3 PREPARATION FOR USE
Preparation for use consists of checking for the cor-
rect line voltage. The line voltage selector on the
rear panel enables the synthesizer to be used with
either 110V or 220V ac. Before leaving the factory,
each synthesizer is preset and tagged for the line
voltage present in the customer’s area. If the actual
line voltage is different from that stated on the tag,
change the LINE SELECT switch (Figure 2-1) to
the correct setting and the line fuses to the correct
value.
2-4 GPIB SETUP AND
INTERCONNECTION
The synthesizer provides automated microwave
measurements via the GPIB. The following para-
graphs provide information about interface connec-
tions, cable requirements, and the addressing of the
synthesizer.
