8、document summarizes the extensive battery of tests performed by the ARRL Laboratory for each unit that is featured in QST Product Review. For all tests, there is a discussion of the test and test method used in ARRL Laboratory testing. For most tests, critical conditions are listed to enable other e

9、ngineers to duplicate our methods. For some of the tests, a block diagram of the test setup is included. The ARRL Laboratory has a document, the ARRL Laboratory Test Procedures Manual, that explains our specific test methods in detail. This manual includes test descriptions similar to the ones in th

10、is report, block diagrams showing the specific equipment currently in use for each test, along with all equipment settings and specific step by step procedures used in the ARRL Laboratory. While this is not available as a regular ARRL publication, the ARRL Technical Department Secretary can supply a

11、 copy at a cost of $20.00 for ARRL Members, $25.00 for non-Members, postpaid. Most of the tests used in ARRL product testing are derived from recognized standards and test methods. Other tests have been developed by the ARRL Lab. The ARRL Laboratory test equipment is calibrated annually, with tracea

12、bility to National Institute of Standards and Technology (NIST). Most of the equipment is calibrated by a contracted calibration laboratory. Other equipment, especially the custom test fixtures, is calibrated by the ARRL Laboratory Engineers, using calibrated equipment and standard techniques. The u

13、nits being tested are operated as specified by the equipment manufacturer. The ARRL screen room has an ac supply that is regulated to 117 or 234 volts. If possible, the equipment under test is operated from the ac supply. Mobile and portable equipment is operated at the voltage specified by the manu

14、facturer, at 13.8 volts if not specified, or from a fully charged internal battery. Equipment that can be operated from 13.8 volts (nominal) is also tested for function, output power and frequency accuracy at the minimum specified voltage, or 11.5 volts if not specified. Units are tested at room tem

15、perature and humidity as determined by the ARRL HVAC system. Also, units that are capable of mobile or portable operation are tested at their rated temperature range, or at 10 to +60 degrees Celsius in a commercial temperature chamber. ARRL Product Review testing typically represents a sample of onl

16、y one unit (although we sometimes obtain an extra unit or two for comparison purposes). This is not necessarily representative of all units of the same model number. It is not uncommon that some parameters will vary significantly from unit to unit. The ARRL Laboratory and Product Review editor work

17、with manufacturers to resolve any deviation from specifications or other problems encountered in the review process. These problems are documented in the Product Review. Units used in Product Review testing are purchased off the shelf from major distributors. We take all necessary steps to ensure th

18、at we do not use units that have been specially selected by the manufacturer. When the review is complete, the unit is offered for sale in an open mail bid, announced regularly in QST . Related ARRL Publications and Products: The ARRL Handbook for Radio Amateurs has a chapter on test equipment and m

19、easurements. The book is available for $32.00 plus $6 shipping and handling. The Handbook is also now available in a convenient, easy to use CD-ROM format. In addition to the complete Handbook text and graphics, the CD-ROM includes a search engine, audio clips, zooming controls, bookmarks and clipbo

20、ard support. The cost is $49.95 plus $4.00 shipping and handling. You can order both versions of the Handbook from our web page at http:/www.arrl.org, or contact the ARRL Publications Sales Department at 888-277-289 (toll free). It is also widely stocked by radio and electronic dealers and a few lar

21、ge bookstores. The ARRL Technical Information Service has prepared an information package that discusses Product Review testing and the features of various types of equipment.

Page 4 Transmitter Output Power Test description: One of the first things an amateur wants to know about a

23、 transmitter or transceiver is its RF output power. The ARRL Lab measures the CW output power for every band on which a transmitter can operate. The unit is tested across the entire amateur band and the worst-case number for each band is reported. The equipment is also tested on one or more bands fo

24、r any other mode of operation for which the transmitter is capable. Typically, the most popular band of operation for each mode is selected. Thus, on an HF transmitter, the SSB tests are done on 75 meters for lower sideband, 20 meters for upper sideband, and AM tests are done on 75 meters, FM tests

25、are done on 10 meters, etc. This test also compares the accuracy of the units internal output-power metering against the ARRL Laboratorys calibrated test equipment. The purpose of the Transmitter Output-Power Test is to measure the dc current consumption at the manufacturers specified dc-supply volt

26、age, if applicable, and the RF output power of the unit under test across each band in each of its available modes. A two-tone audio input, at a level within the manufacturers microphone-input specifications, is used for the SSB mode. No modulation is used in the AM and FM modes. Many transmitters a

27、re de-rated from maximum output power on full-carrier AM and FM modes. In most cases, a 100-watt CW/SSB transmitter may be rated at 25 watts carrier power on AM. The radio may actually deliver 100 watts PEP in AM or FM but is not specified to deliver that power level for any period of time. In these

28、 cases, the published test-result table will list the AM or FM power as being as specified. In almost all cases, the linearity of a transmitter decreases as output power increases. A transmitter rated at 100 watts PEP on single sideband may actually be able to deliver more power, but as the power is

29、 increased beyond the rated RF output power, adjacent channel splatter (IMD) usually increases dramatically. If the ARRL Lab determines that a transmitter is capable of delivering its rated PEP SSB output, the test-result table lists the power as being as specified. Key Test Conditions: Termination:

While it is most important for QRP rigs, the ARRL Lab tests the current consumption of all equipment that can be operated from a battery

35、 or 12-14 Vdc source. The equipment is tested in transmit at maximum output power. On receive, it is tested at maximum volume, with no input signal, using the receivers broadband noise. Any display lights are turned on to maximum brightness, if applicable. This test is not performed on equipment that can be powered only from the ac mains.
