Universal radio test set RST-430

Universal test Radio for the full technical maintenance and repair of FM and AM radio stations VHF RST-430 is a multi-purpose measuring device for maintenance of communications equipment in the premises and in the field. function RF generator LF generator Frequency Power-o-Meter Transmitter meter load test measurer modulation Measuring the amount of distortion voltmeter AC voltage Measured parameters The ratio of carrier / noise the frequency of the transmitter The ringing frequency the frequency deviation The sensitivity of the modulation input of the transmitter Total harmonic distortion of the modulation characteristics of the transmitter The sensitivity of the receiver, including the signal-to-noise method and distortion (SINAD) Receiver output voltage selectivity the distortion factor The threshold of the noise Blanker Standard delivery test set Radio RST-430 AC220 power adapter / 12 V Certificate, Instrument, test lead, user manual Cable set Case Specifications 1. RF generator Baseband 90 ... 210 MHz Permitted additional strip upon agreement with the customer (frequency step 1 kHz) 100 kHz ... 470 (527) MHz the error of the carrier <10-6 * Deviation in FM mode 0,1 ... 20 kHz (step 10 Hz) setting accuracy measurement Error <10% The output level (step 1 dBm) -60 (-80) ... -120 dBm Level setting accuracy <3dB Additional error of <0.1 µv Amplitude modulation (option) 0 ... 100% error of QAM <10% The frequency of the modulation signal (step 1 Hz) 20 Hz ... 20 kHz Generator 2. LF Frequency band (step1 Hz) 20 Hz ... 20 kHz The instability frequency <0.2 Hz The output level (step 10 mV) 0 ... 2 V Installation error <(0,01 + 0,03 * U) V Total harmonic distortion <0,3% 3. Measurer modulation Deviation FM 0,1 ... 20 kHz Error <(0,1 + 0,1 * D) kHz Modulation rate 0 ... 100% Error <10% 4. Frequency meter LF 10 Hz ... 100 kHz RF 40 MHz To 240 MHz (... 1000 MHz) The instability of the reference generator <10-6 * 5. Measuring distortion Frequency band 20 Hz ... 10 kHz The range of 1 ... 50% Error <(5 + 5 * Kmst)% 6. DC voltmeter The Range Is 0 ... 30 V Error <(2 + 2 * (Uk / Umst))% 7. The AC voltmeter The Range Of 0.02 ... 20 Frequency band 20 Hz ... 20 kHz Error <(0,02 + 0,03 * U) V 8. Power meter Level 0.5 to 20 watts (50 watts - W / external attenuator FAD-2, up to 100 watts - W / FAD-3, in agreement with the customer) Please note that when using difficult attenuators type of FAD or analogues for measuring parameters of a radio transmitter with an output power of 20 W, the power value is measured with the device must be multiplied by the coefficient of attenuation (fading) of an attenuator according to the formula of rett = 10 to the power of Ratt, dB / 10 ) Error <[10+ (RC / Modified Directly)]% * If necessary, reference oscillator with a stability of 5 × 10-7 can be added. NVRAM can be used to store test results. The device can be supplied with a power supply that provides at least 4 hours in offline mode Also, the battery of solar cells can be used as a power source.
