In September 2014, some of the test equipment manuals (Agilent/HP, Boonton, Fluke, and some miscellaneous others) were transferred to the BAMA (Boat Anchor Manual Archive) web site as they were not pertinent to the concept and purpose of this web site.

In October 2014, more of the test equipment manuals (Heath, Marconi, Tektronix, Triplett, and CT Systems/Wavetek) were transferred to KO4BB's web site to be hosted there. Click on "Manuals" then use the search tool to find a manual based on the manufacturer or model number.

Please send future manuals for the above manufacturers to the BAMA or KO4BB web sites.

We will continue to host manuals for companies whose main business is communications test equipment.

Manufacturer's Manuals and Datasheets:

Aeroflex / IFR Index     Information and modifications for test equipment manufactured by Instrument Flight Research corp, better known as IFR, now a part of Aeroflex.
Automated Industrial Electronics Corp Model 2TSG-1 Two Tone Generator Instruction Manual   986 kB PDF file
As a result of a request made in a comment thread on the repeater-builder mailing list John Kernkamp WB4YJT scanned his manual, took a front panel photo and sent both in.
This is a unit that can generate two clean audio tones from 10 Hz to 9.999 kHz, and send tone A or a two-tone A-B sequence with variable delay, duration and level. It was a very popular service monitor add-on for doing CTCSS generation, tone burst, single tone, or two-tone pagers. While they call it an "instruction manual" it contains all available documentaton including service info and schematics.
Bird Electronic Corp. Index     Information on RF products including the Thruline™ and Termaline™ wattmeters and dummy loads.
Coaxial Dynamics Inc (Coaxial, or CDI, at makes Bird compatible and clone products, such as wattmeters, elements, and dummy loads. Their elements are interchangeable with Bird equivalents (same sizes, ranges, etc) and at one time they were a bit less-expensive than Bird's. Their 81000 meter is functionally equivalent to the classic Bird 43 meter, however it has a much bigger case and a much bigger mirrored-scale meter, great for us older folks who have problems reading the small Bird meter. You may see similar-looking meters for sale, with brands like Sola, Sola Basic, or Dielectric. This product line was bought out by CDI.
Cushman Electronics Index     Information about communications test equipment manufactured in the 1970s and 1980s by Cushman.
GAW SINAD / Distortion / Voltmeter Model 1410   215 kB PDF file courtesy of Geoff Fors WB6NVH
Helper Instruments Index     Information for test equipment manufactured by the old Helper Instruments Company.
IFR / Aeroflex Index     Information and modifications for test equipment manufactured by Instrument Flight Research corp, better known as IFR, now a part of Aeroflex.
Lampkin Type 107B Digital Frequency Meter and Type 107C Communication Service Monitor Operation and Service Manual   4.1 MB PDF file dated Oct 1972 compliments of Greg Miller K2GTM
Measurements (Boonton) Corp. Model 560FM Standard Signal Generator Manual   1.3 MB PDF file Courtesy of Bob WA1MIK
Motorola Test Equipment Index     Moto has made their own test equipment or private-labeled other manufacturers (like Measurements Corp. or Boonton) since the late 1940s. They've also worked with other companies to design specialized equipment, like the telephone line test set that was co-designed with Triplett and made by them, but sold by both.
Radio Frequency Labs 5950A Crystal Impedance Meter Manual   142 kB PDF file
Ramsey Electronics Index     has a few pieces of radio and communications test equipment. Unfortunately they no longer sell kits.
Telonic 1019 Sweep Signal Generator Manual   3.2 MB PDF file
VIZ WD-76x series Digital Wattmeters Manual   410 kB PDF file courtesy of Eric Lemmon WB6FLY.
See the article below about improving the WD-766A.

Several other manufacturers also make radio and communications test equipment. You may find more information on their respective index pages on this site.

Construction and Modification Articles:

Improving the Accuracy of the WD-766A Digital Wattmeter   142 kB PDF file by Robert W. Meister WA1MIK.
Goes along with the VIZ WD-76X manual above.
A Poor Ham's Deviation Meter   by Robert W. Meister WA1MIK.
A theory and practice article on measuring deviation of FM transmitters.
Build Yourself a Service Monitor? Well, sort of.   By Tom Alldread VA7TA
A simple deviation monitor circuit used with a scanner receiver.
Poor Man's Spectrum Analyzer   A Spectrum Analyzer / Tracking Generator Kit by Science Workshop (offsite link)
If anyone wants to write a review article after acquiring one we'll put it on this page.

Other Information:

A lot of equipment, including many HP and IFR and Motorola spectrum analyzers and service monitors, have an RF fuse, in the input or output connector. The original manufacturer is Littelfuse Corp, and they named it a "Pico Fuse". Other companies now make a similar and interchangeable product. Two forms are made: one is axial about the size and shape of a 1/4 watt or 1/8 watt resistor, the other is a small cylindrical plug-in element a little smaller than a pencil eraser. The name "Pico Fuse" is a LittelFuse corporate trademark, but has become synonymous with the fast acting fuse in either shape.

Jameco, Digikey and Mouser all sell these fuses. Here's a 214 kB PDF datasheet for the axial fuses (which usually have a solid color body in green, yellow, orange or gold). They're available from 1/16 amp through 15 amps, fast-blow and slow-blow; you want the fastest they have.
Here's a 91 kB PDF datasheet for the 373/TR5 series plug-in fuses if you need the round 8.5mm diameter plug-in style. They are available in 50ma (yes, milliamps) through 10 amps. The most common size that I have found in RF test gear (like service monitors) is the 1/16 amp.
