MuxScope

DAB+ · FM analyzer and monitor

Your multiplex, always under control.

Measures and monitors DAB+ multiplexes and FM stations around the clock, reporting every fault with its point in the chain and its start time.

From RF to data, in one chain

The measurement chain follows the signal from RF to data: the first stage shown in amber marks the point of failure.

Analyze

Full analysis of every multiplex from RF to data, with the raw value of every FIG next to the decoded field.

RF and OFDM: SNR and MER at 0.1 dB resolution, level, AGC, ADC clipping, offset in Hz and ppm, FIC CRC errors.
Displays: spectrum, null-symbol spectrum, constellation and trends.
Ensemble: EId, ECC, LTO, time, reconfigurations; every FIG with its raw value.
Subchannels and services: start address and size in CU, EEP/UEP, bitrate, FEC and multiplex capacity; SId, labels, PTy, MP2 and HE-AAC v1/v2, SBR, PS.
Data and audio errors: DLS, DL+, MOT SlideShow, SPI/EPG; RS corrected and uncorrectable, AAC CRC, error-free seconds.

Monitor

Continuous monitoring: the tuner cycles over the watched multiplexes, 60 s dwell each (adjustable), and scans Band III in the background, one unwatched channel per cycle.

Thresholds with hold-off, confirmed over several measurement cycles.
Content: audio silence, stuck DLS or slideshow.
Reference configuration: missing or added services and any deviation from it.
Critical, Warning, Info, with acknowledge, shelve and maintenance windows.
GPS: receiver position and time drift vs GPS.

Alert and report

Every fault is reported with its point in the chain and its start time: on mobile devices, in the control room and in reports.

Notifications by e-mail, webhook, MQTT, browser push, SNMP trap and Telegram, plus a REST API.
Availability per service and multiplex over 24 h, 7 and 30 days; PDF and CSV reports.
History: trends up to 365 days, event log with ms timestamps, CSV export.

English and Italian, light and dark themes.

TII identification and SFN geometry

On the impulse response MuxScope identifies the TII of every received transmitter, with delay and level. From the transmitter database it shows each one on the map, with distance and delay from the receiver.

Drive test

In the car, MuxScope logs the levels of DAB+ multiplexes and FM stations along the GPS track and shows them on a map.

FM monitoring in the same cycle

FM stations join the DAB+ multiplexes in the same continuous cycle, with the same thresholds.

MuxScope FM readings: level, C/N, multipath, offset, MPX and deviation
Measurements: level, C/N, multipath, offset, MPX power, deviation, pilot, loudness (LUFS).
RDS: PI, PS, RT, PTY, TP/TA, alternative frequencies (AF), RDS block errors.

Front-panel display

The 2.79″ front display shows status and the readings of the multiplex on air, with a QR code for quick access to the web interface.
