Enhanced multi-source synchronized (GNSS, IRIG-B), configurable 8 outputs (IRIG-B, PPS, Digital, 10Mhz) Time and Frequency generator TMG5020

jcp@timelinkmicro.com — Tue, 21 Jan 2020 08:34:48 +0000

The TMG5020 time and frequency generator is a highly configurable equipment synchronized via GNSS, NMEA/PPS or IRIG-B. It features 8 individually configurable outputs amongst IRIG-B, PPS, Digital pulse and analog 10Mhz.

The TMG5020 can synchronize on a choice of time source and can manage several sources with a priority list for redundancy.

PPS accuracy is within +-100ns of PPS UTC when synchronized by GNSS.

It also features an NTP server.

Optionnally this equipement can provide countdown.

The IRIGB standard

jcp@timelinkmicro.com — Thu, 01 Jan 1970 00:00:00 +0000

Communication systems, data handling systems, tracking and telemetry systems require time-of-the day information for data correlation with time.
Parallel and serial formatted time codes are used to efficiently interface the timing system to the user system. Parallel time codes are defined in IRIG standard 205-87. Standardization of time code is necessary to ensure system compatibility among the various ranges, ground networks, industrial projects and international cooperation.The IRIG standard 200-98, define IRIG serial time code formats. The characteristics of six serial time codes presently used are defined :A, B, D, E, G, H.For a detailed presentation of these characteristics, download the pdf version of the IRIG standard :
IRIGB standard 200-04, pdf file (372 Ko) For a first introduction to IRIGB characteristics, we provide the main information through the two following figures :

The figure below shows the IRIG format B: BCD time-of-the year in days, hours, minutes and seconds

Transcodeur de code temps paramétrable IRIGB vers RS232/422

jcp@timelinkmicro.com — Mon, 17 Apr 2017 14:33:22 +0000

Le transcodeur SR1118 assure le transcodage d’un code horaire analogique IRIG B et produit une trame horaire RS232/RS422 ainsi qu’un signal 1PPS . Les codes de temps sont basés sur une porteuse sinusoïdale de fréquence 1 KHz modulée en amplitude (1/3, 1/1).
L’équipement se présente sous forme d’un tiroir rackable de hauteur 1 U avec les faces avant et arrière peintes et sérigraphiées.

L’équipement fournit 10 sorties RS232/RS422 et 5 sorties 1 PPS sur sa face arrière.
L’équipement peut aussi traiter les codes AFNOR et IEEE-1344 qui contiennent l’information « année »

L’équipement peut être télégéré et commandé à travers une liaison Ethernet 10/100 Mbit/s et le protocole http. L’équipement est accessible par un browser internet standard.

Le format du message de sortie est totalement paramétrable.
A partir d’un browser on peut configurer directement une chaine de caractère permettant de décrire la séquence des informations en sortie.

A new line of multprotocol time display

jcp@timelinkmicro.com — Mon, 19 May 2014 14:16:53 +0000

The SR1245-1255 new product line displays IRIGB, RS422 or Ethernet frame time code. With automatic selection of the available time source.

SR1245 and SR1255 are robust and light time displays, that can be used in a rack or wall mounted.
They come in two models:

SR1245, 2U height, width 19’, 80 mm depth, rack mount or wall mount. 7 red LED segments, 38 mm height, visibility > 15m.
SR1255, 144 mm height, 660 mm width, 80 mm depth, wall mount. 7 red LED segments, 76 mm height, visibility > 30 m.
