Axel Technology Lynx Digital Broadcast FM Tuner-Monitoring

Description Specifications Axel Technology LYNX Digital Broadcast FM Tuner/monitoring. Lynx is an evolved Broadcast Digital FM Tuner, designed for receiving, monitoring, visualize and listen the FM radio signals. The built in web interface allow to multiple users to visualize all the parameters and details of the incoming signal. The tuned frequency’s audio is available on the analog balanced output (XLR), on the digital output AES/EBU (XLR), on the headphone output and via streaming. At the same time. The quality and accuracy of the built-in tuner allow a very strict analysis of the tuned frequency, the modulation and the RDS data decoding. The Lynx’s display always show the tuned frequency and, cyclically, all the following parameters: Receiving: – RF Level incoming – Multipath – Carrier Offset Deviation: – MPX – Audio – Pilot and RDS Decoding RDS: – PS – PI – BLER – TA – TP – MS – DI – PTY / PTYN – AF Presence – RT / RT – TMC The display allow you also to finetune and adjust all the setting of Lynx as: – IP Ethernet port – Digital and Analog level output – Time and treshold alarm – Headphone level On the frontal panel the headphone output allow you to listen the tuned frequency. The led panel (STATU LED PANEL) show you in a clear way the receiving status: – Tuned – Stereo – RDS – 3 different alarms: Low RD, Low Audio and RDS Errors.   The built in web server allow to preview the following details: Receiving: – RF Level incoming – Carrier Offset – Multipath – Adjacent Channel – Alternative Channel Deviation: – MPX – Audio – Pilot – RDS Audio parameter decodified: – L/R RMS – L/R peak – Imnbalance – Mono – MPX Power Audio spectrum streaming received. RDS Decoding: PS, RT, PI, EON, BLER, CT, TP, TA, MS, DI, PTY, PTYN, PIN, transmitted groups. Presence of services of CT, AF, RT, RT , TMX, EON, IH, LA, EG, ILS, LSN. List of all the alternative frequency, up to a 64 lists, A/B list analyzes and REG check. Preview of EON data. Page welcome to RDS statistic analysis and decoding of the RDS flux with the possibility of download for a better analysis.   Features:  Real time measurement – High quality tuner  Signal analysis of: RF, MPX, AUDIO and RDS  Built in web server for remote access  Audio over IP streaming for monitoring  Decoder RDS with complete data decoding  Double ports for Net connection  Analog balanced output and AES/EBU on XLR  High shielded against strong RF fields Main Power 100 Vac – 240 Vac 50/60 Hz internal, universal power supply Power consumption 25 W Power connector IEC plug filter with internal fuse 2.0 AT Headphones Stereo Jack 6.3 mm Safety and EMC Compliant to CE laws Working temperature 0° to 50° C (storage -5 to 50 °C) Housing dimensions 19 inch x 1u x 240 mm (depth) Weight 3.5 kg RF TUNERS Tuner frequency 87.5 MHz ‐ 108.0 MHz Tuner step 10 kHz RF tuning stability /- 500 Hz RF input sensitivity 20 to 120 dBµV RF input nominal level 80 to 100 dBµV RF inputs main 1x BNC, with 50 Ohm unbalanced Max frequency deviation 125 kHz IF filter bandwidth 34 kHz to 138 kHz – Manual or automatic Input RF level 30 dBµV – 120 dBµV with internal attenuator Selectivity at ± 120 kHz > -3 dB Selectivity at ± 200 kHz > -40 dB Selectivity at ± 300 kHz >- 50 dB Selectivity at ± 400 kHz >-65 dB Image rejection @ 22.5 kHz 70 dB Adjacent channel rejection 63 – 65 dB Alternate channel rejection 65 – 72 dB THD @ dev=75 kHz 0.05 – 0.1 % Mono (S N)/N 75 dB typ – 68 dB min (No A-Weighting 30 Hz – 15 kHz) STEREO DECODERS Stereo (S N)/N 61 dB Stereo/61 dB mono @ 40 dBµV 65 dB Stereo @ 50 dBµV 80 dB Stereo @ 70 dBµV Pilot 19kHz suppression 55 dB (Stereo modulation L = 1, R = 0,Deviation=67.5 kHz, Pilot deviation=6.75 kHz) Stereo THD N Measures @ 70 dBuV with 75 kHz deviation 100 Hz – 0.055 % 1 kHz – 0.061 % 5 kHz – 0.19 % 10 kHz – 0.46 % Stereo separation 45 dB (Stereo modulation L = 1, R = 0,Deviation=67.5 kHz, Pilot deviation=6.75 kHz) 48 dB @ 400 Hz 48 dB @ 1 kHz 48 dB @ 5 kHz 38 dB @ 10 kHz 38 dB @ 14.7 kHz RDS DECODER RDS sensitivity 20 dBµV (dev f = 2 kHz, RDS BLER < 5%) RDS synchronization time 80 ms (dev f = 2 kHz RF input = 60 dBµV) RDS PI lock time 100 ms (dev f = 2 kHz RF input = 60 dBµV) RDS data decoding and streaming RDS level indication and deviation (voltage, kHz and dBr) RDS data decoding services PS, PI, M/S, DI, TP, TA, AF, AF List Presence A/B Method, Scrolling PS, AF EON, Radio Text, Radio Text Plus, CT, PTY, PIN, IH, TMC, EWS, TDC.
