2. TECHNICAL REQUIREMENTS

2.1. Test Conditions

2.1.1. General Provisions

Tests must be conducted under the test conditions specified in Appendix A of QCVN 18:2022/BTTTT. Additional test conditions relevant to PMR equipment are specified in this regulation.

For emission and immunity tests, test modulation and test configurations shall comply with the provisions from 2.1.2 to 2.1.5 of this regulation.

2.1.2. Test Signal Configuration

2.1.2.1. Configuration of Test Signals at Transmitter Input

As per A.2.2, QCVN 18:2022/BTTTT.

2.1.2.2. Configuration of Test Signals at Transmitter Output

As per A.2.3, QCVN 18:2022/BTTTT, with the following modification:

The transmitter must operate at its maximum rated RF output power and be modulated in a typical test mode (see 2.1.5).

2.1.2.3. Configuration of Test Signals at Receiver Input

As per A.2.4, QCVN 18:2022/BTTTT, with the following modification:

At the start of and during the test, a communication link must be established and maintained.

2.1.2.4. Configuration of Test Signals at Receiver Output

As per A.2.5, QCVN 18:2022/BTTTT.

2.1.2.5. Configuration of Test Signals for Transmitter and Receiver Together (as a System)

The transmitter and receiver may be tested for immunity as a system when combined as a transceiver. In this case, the transceiver or transmitter and receiver must be placed within the test environment and simultaneously exposed to immunity test signals.

For transceivers or separate transmitters and receivers operating on the same frequency, the desired output signal of the transmitter may be used through an appropriate attenuator and fed to the receiver input as a desired receive signal.

For immunity testing of duplex transceivers, the EUT must be configured in a loopback mode, adhering to the above conditions.

2.1.3. Excluded Bands

2.1.3.1. Excluded Bands for Receivers or Receiver Sections in Transceivers

The excluded bands for receivers and receiver sections in transceivers are frequency ranges defined based on the operating band, as declared by the manufacturer:

·                    The lowest frequency of the excluded band is obtained by subtracting 5% of the center frequency of the operating band or 10 MHz from the lowest frequency of the operating band, whichever yields the lowest frequency.

·                    The highest frequency of the excluded band is obtained by adding 5% of the center frequency of the operating band or 10 MHz to the highest frequency of the operating band, whichever yields the highest frequency.

The operating band is the widest frequency range in which the receiver can operate without reprogramming or rearrangement.

Note: The excluded band segments for receivers must align with the blocking bands in the test.

2.1.3.2. Excluded Bands for Transmitters

The excluded band for transmitters is the frequency range extended on both sides of the nominal operating frequency of the transmitter by ±25 kHz.

For TETRA equipment, the excluded band for transmitters is the frequency range extended on both sides of the nominal operating frequency by ±50 kHz.

2.1.4. Narrowband Responses for Receivers

Narrowband responses on receivers or the receiver sections of transceivers (duplex) occurring during immunity testing at discrete frequencies are identified as narrowband responses (spurious responses) using the following method:

If, during testing, the RF immunity test signal (see 2.2.3 and 2.2.6, QCVN 18:2022/BTTTT) causes non-compliance of the receiver or receiver section of the transceiver with specific criteria (see 2.3), this non-compliance must be identified as either a narrowband response or a broadband phenomenon. Therefore, the frequency of the test signal is increased by twice the nominal 6 dB bandwidth of the IF filter directly preceding the receiver’s demodulator or the receiver section of the transceiver, or, where applicable, the device bandwidth specified for operation as determined by the manufacturer. The test is repeated with the test signal frequency reduced by the same amount.

If the receiver or the receiver section of the transceiver complies with the specific criteria in one or both detuned cases, the response is considered a narrowband response.

If the receiver or the receiver section of the transceiver remains non-compliant with the specific criteria in one or both detuned cases, this indicates that the detuning has placed the signal at an undesired frequency corresponding to another narrowband response. In this case, the above procedure is repeated, increasing or decreasing the test signal frequency by 2.5 times the reference bandwidth.

If the receiver or the receiver section of the transceiver still fails to comply with the specific criteria in one or both detuned cases, the phenomenon is considered broadband, and the device fails the EMC test.

For immunity tests, narrowband responses must be disregarded.

For multifunctional radio equipment and/or ancillary equipment, more than one set of testing requirements specified in Table 1 and Table 4 of QCVN 18:2022/BTTTT must be considered.

2.2.6. Quality Assessment of Equipment Providing Voice Channels

2.2.6.1. Introduction

Voice quality is assessed using the audio interference method specified in Section 2.2.6.2 or the audio distortion method specified in Section 2.2.6.3.

2.2.6.2. Assessment of Voice Channels Using the Audio Interference Method

The measurement applies only to devices capable of voice communication. Voice channels must be in standby mode.

Establish a communication link using a TETRA system simulator or a measuring device (hereinafter referred to as the "test system"). The test signals to be applied must be agreed upon by the testing unit and the equipment manufacturer.

The EUT in transmit/receive mode must meet the following conditions:

·                    The EUT must be configured to operate at maximum transmit power;

·                       Prior to testing, the reference level of the voice output signal must be recorded in both the uplink and downlink directions of the measuring device, as shown in Figure 2. The reference level at the ear reference point (ERP) must be 0 dBPa at a frequency of 1020 Hz or +5.0 dBPa at the speaker for the downlink, and -5 dBPa at the mouth reference point (MRP) at a frequency of 1020 Hz or at the microphone for the uplink. These nominal audio measurement levels should conform to the types of TETRA devices and other audio measurement configurations;

·                    The output signal level from the EUT's voice channel in the downlink direction at the earpiece of a mobile or handheld device must be determined by measuring the sound pressure level (SPL), as shown in Figure 1;

·                       Measure the voice output signal level of the test system restored through the uplink voice channel. Background noise for the microphone must be minimized.

NOTE: In the case of mobile equipment measurements, the ERP is the loudspeaker and the MRP is the microphone.

NOTE 1: During the calibration for the upward direction, the EUT is present but during the calibration for the downward direction, the EUT is absent.

NOTE 2: When the EUT has a loudspeaker, the reference level shall be +5.0 dBPa at 1 020 Hz.

Figure 2 - Calibration diagram - Acoustic interference method

2.2.6.3. Assessment of Voice Channels Using the Audio Distortion Method

The measurement applies only to devices capable of voice communication. Voice channels must be in standby mode.

Establish a communication loop through the TETRA test system. The testing laboratory and the equipment manufacturer must agree on the desired RF signals to be applied:

·        The EUT must operate at maximum transmission power;

·        A connection between the EUT and the test system must be established. In this system, the uplink signal received from the EUT is looped back to the EUT as a downlink signal. The looping process in the test system must ensure that the repeated signal retains its digital form or is otherwise unaffected;

·        A 1,020 Hz signal with a level within the dynamic range of the voice channel must be applied to the microphone at the Mouth Reference Point (MRP);

·        After looping, the audio signal must be measured at the Ear Reference Point (ERP) using an acoustic transducer with a non-metallic acoustic guide. The signal from the acoustic transducer must be fed to an audio distortion analyzer placed outside the test environment;
