9、oduct 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 engineers to duplicate our methods. For some of the tests, a block diagram of the test setup is included. The ARRL Laboratory

10、 has a document, the ARRL Laboratory Test Procedures Manual, that explains our specific test methods in detail, with a test description similar to the one in this report, a block diagram showing the specific equipment currently in use for each test, along with all equipment settings and a specific s

11、tep by step procedure used in the ARRL Laboratory. While this is not available as a regular ARRL publication, the ARRL Technical Department Secretary can supply a 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 f

12、rom recognized standards and test methods. Other tests have been developed by the ARRL Lab. The ARRL Laboratory test equipment is calibrated annually, with traceability to National Institute of Standards and Technology (NIST). Most of the equipment is calibrated by a contracted calibration laborator

13、y. Other equipment, especially the custom test fixtures, is calibrated by the ARRL Laboratory Engineers, using calibrated equipment and standard techniques. The units being tested are operated as specified by the equipment manufacturer. The ARRL screen room has an ac supply that is regulated to 117

14、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 manufacturer, at 13.8 volts if not specified, or from a fully charged internal battery. Equipment that can be operated from 13.8 volts (nomina

15、l) 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 temperature and humidity as determined by the ARRL HVAC system. Also, units that are capable of mobile or portable operation are tested at th

16、eir rated temperature range, or at - 10 to +60 degrees Celsius in a commercial temperature chamber. ARRL Product Review testing represents a sample of only one unit (although we sometimes obtain an extra sample or two for comparison purposes). This is not necessarily representative of all units of t

17、he 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 with manufacturers to resolve any deviation from specifications or other problems encountered in the review process. These problems are document

18、ed 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 that 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 op

All Rights Reserved. - Page 5 Transmitter Output Power: Test description: One of the first things an amateur wants to know about a transmitter or r

31、eceiver 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 for any other mode of

32、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 are done on 10 meter

33、s, 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 voltage, if applicable,

34、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 are derated from maxi

35、mum 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 cases, the published

36、 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 increased beyond the

37、 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.

41、est Description: The noise floor of a receiver is the level of input signal that gives a desired audio output level that is equal to the noise output level. This is sometimes called minimum discernible signal (MDS), although a skilled operator can copy a signal at considerably less than the noise fl

42、oor. Most modern receivers have a noise floor within a few dB of perfect. A perfect receiver would hear only the noise of a resistor at room temperature. However, especially for HF receiving systems, the system noise is rarely determined by the receiver. In most cases, external noise is many dB high

43、er than the receivers internal noise. In this case, it is the external factors that determine the system noise performance. Making the receiver more sensitive will only allow it to hear more noise. It will also be more prone to overload. In many cases, especially in the lower HF bands, receiver perf

44、ormance can be improved by sacrificing unneeded sensitivity by placing an attenuator in front of the receiver. The more negative the sensitivity number expressed in dBm, or the smaller the number expressed in voltage, the better the receiver. Key Test Conditions: 50-ohm source impedance for generato

45、rs.; Receiver audio output to be terminated with specified impedance. Receiver is tested using 500 Hz bandwidth, or closest available bandwidth to 500 Hz.

The range expressed is the range over which the receiver can be tuned. Most receivers exhibit some degradation of sensitivity near the limits of their tuning range. In cases where this degradation renders the receiver unusable, we report both the actual and useful tuning range.
