Test Equipment Manuals
and Related Articles
Compiled by Mike Morris WA6ILQ
Maintained by Robert Meister WA1MIK
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 Data Sheets:

Two Tone Generator Instruction Manual 986 kB PDF
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. Information on RF products including the Thruline™ and Termaline™ wattmeters and dummy loads.|
|Coaxial Dynamics Inc (Coaxial, or CDI, at http://www.coaxial.com) 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.|

|Motorola 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.|

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.

If anyone wants to write a review article after acquiring one we'll put it on this page.
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.
