SIST EN 300 433-1 V1.1.2:2003 is the SIST adoption of the ETSI European Standard for Double Side Band (DSB) and/or Single Side Band (SSB) amplitude modulated citizen's band (CB) radio equipment. It specifies technical characteristics, test conditions, and measurement methods for equipment used in the CB land mobile service, so manufacturers and test laboratories can check whether a radio meets the minimum performance levels defined for type testing.
What does SIST EN 300 433-1 V1.1.2:2003 specify?
SIST EN 300 433-1 V1.1.2:2003 covers CB radio equipment operating in the 26,960 MHz to 27,410 MHz band with 10 kHz channel spacing and intended for analogue speech and/or data transmission. It sets minimum characteristics for base stations, mobile stations, and two categories of hand-portable stations, with provisions for equipment using an external antenna socket or an integral antenna.
The document focuses on technical limits and how to measure them. It does not try to describe every feature a user might want, and it is organized around general conditions, transmitter requirements, receiver requirements, measurement uncertainty, and two normative annexes.
| Annex | What it covers |
|---|---|
| Annex A | Radiated measurement sites and arrangements, including outdoor and indoor sites |
| Annex B | Specification for adjacent channel power measurement arrangements |
What are the key requirements of SIST EN 300 433-1 V1.1.2:2003?
SIST EN 300 433-1 V1.1.2:2003 ties type testing to declared equipment configuration, channel range, modulation mode, and test conditions. In practice, this means the manufacturer must present a production model and declare the switching range, antenna arrangement, and rated powers before measurements begin.
Channel use and modulation
The standard requires transmission and reception on the same channel in single frequency simplex mode, with carrier frequencies listed for the permitted channel plan. Multi-channel equipment is allowed only within those listed channels, and equipment capable of both A3E and J3E must be tested in both modes. For a buyer or engineer, this means the radio cannot be treated as a generic 27 MHz unit - it is assessed against a fixed CB channel structure.
User controls and operating mode
Controls that could increase interference or cause improper operation must not be accessible to the user, and transmit/receive switching must use a non-locking ptt or voice activated switch, or a locking version with a transmitter time-out. Voice activated switching must not respond to ambient noise. This matters because the user should not be able to defeat the intended interference protection or hold the transmitter on indefinitely.
Transmitter limits
Clause 5 sets limits for frequency error, transmitter RF power, adjacent channel power, spurious emissions, and transient frequency behaviour. DSB power is limited by carrier power, while SSB power is limited by Peak Envelope Power (PEP). In practice, the test lab checks both steady-state output and unwanted emissions, because both affect spectrum use and interference to other services.
Receiver limits
For equipment with an external antenna connector, the receiver is checked for maximum usable sensitivity, adjacent channel selectivity, intermodulation response rejection, spurious radiation, and spurious response rejection. These limits show whether the receiver can hear a wanted signal in the presence of nearby or unwanted signals, which is important for real CB use in crowded radio environments.
Test conditions and uncertainty
Clauses 6 and 10 define normal and extreme test conditions, power-source arrangements, temperature limits, and the measurement uncertainty that must be reported. The uncertainty table is part of the decision process, so the measured value is not taken alone - it is interpreted together with its stated uncertainty.
What terms does SIST EN 300 433-1 V1.1.2:2003 define?
- Base station - equipment with an antenna socket for an external antenna, intended for fixed-location use.
- Mobile station - equipment with an antenna socket for an external antenna, normally used in a vehicle or as a transportable station.
- hand-portable station - equipment with an antenna socket, an integral antenna, or both, normally carried on a person or held in the hand.
- integral antenna - an antenna connected to the equipment without a 50 Ω external connector and treated as part of the equipment.
- Double Side Band (DSB) - DSB amplitude modulation, identified in the document as A3E.
- Single Side Band (SSB) - SSB amplitude modulation with suppressed carrier, identified as J3E, using USB or LSB.
- Peak Envelope Power (PEP) - the power measure used for SSB transmitter output.
- ptt - push-to-talk, the switch used to change between transmit and receive.
Who uses SIST EN 300 433-1 V1.1.2:2003?
SIST EN 300 433-1 V1.1.2:2003 is used by CB radio manufacturers, test laboratories, and regulatory or notified bodies that assess equipment performance. It is also relevant to design and quality teams that need to set up prototype tests, choose test fixtures, document declared powers, and prepare equipment for type approval or conformity assessment.
What changed in SIST EN 300 433-1 V1.1.2:2003 from the previous edition?
SIST EN 300 433-1 V1.1.2:2003 is an editorial revision of ETS 300 433 following the publication of EN 300 433-2. The document history also shows earlier publication as ETS 300 433 V1.1.2 and later publication in EN form.
Which standards are used with SIST EN 300 433-1 V1.1.2:2003?
- ETSI ETS 300 135 - used for angle-modulated CB radio equipment; CB equipment covered here that can also work with angle modulation must meet it as well.
- CISPR Publication No. 16-1 - provides the measuring apparatus and detector requirements used for spurious and adjacent-channel measurements.
- CCITT Recommendation O.41 - provides the psophometric weighting network used for sensitivity and selectivity measurements.
- ETSI ETR 028 - provides the measurement uncertainty method used to interpret test results.
- ETSI ETS 300 680-2 - the EMC standard for CB radio and ancillary equipment.
- Council Directive 89/336/EEC - the EMC directive cited in the references.
What does the SIST EN 300 433-1 V1.1.2:2003 document contain?
The document contains the channel plan, transmitter and receiver limits, test conditions, and the detailed measurement methods used in type testing. It also includes Table 1 for carrier frequencies and channel numbers, Tables 2 to 7 for limits and uncertainty, and Figures 1 and 2 for the transmitter transient-frequency measurement setup and waveform timing. Annex A gives radiated test-site guidance for outdoor and indoor measurements, including anechoic chamber use, while Annex B specifies the adjacent channel power measuring receiver and its IF filter characteristics.
