RUBIDIUM Distribution modules:
The Alpermann+Velte Rubidium "V" series modules are signal distribution, demultiplexer and amplification modules for all outgoing signals available from our Rubidium generator modules. The following signals can be distributed with our RUB "V" series: LTC, IRIG-B, 10 MHz continuous wave, analog clock signals and RS 232/422/485 serial data strings (please view above chart for applicable module/signal).
This distributor and amplifier modules are designed to distribute incoming signals such as a "real time" over long distances and to various signal receivers. Selected modules also have an analog clock driver and can power and control up to 180 of our analog clocks, in up to four different world time zones.
The "VI" and "VM" series modules also have an error monitor function for signal failure(s), enabling a completely redundant outgoing signals. These signals can be monitored with our RUB IE module via SNMP or an internet browser. The VL and VU distribution modules are also demultiplexers for all the time signals available from our GT Time Code Generator. Each output is selectable from available time zones or A,B,C,D;E;F "MTD" times.
"V" series module features… at a glance:
Distributes and amplifies 1:4 RUB GT signals:
-one LTC input to four LTC (EBU/SMPTE) outputs
-one RUB GT input to four RS232/422/485 signals outputs
-one RUB GT input to four analog clock signals
Distributes and amplifies:
-one input to six LTC(EBU/SMPTE) or IRIG-B outputs
-output monitoring with a redundant change-over switcher
Distributes and amplifies:
-two LTC inputs to four LTC (EBU/SMPTE) outputs
-four different time zones possible
(demultiplexed from Alpermann+Velte's MTD A,B,C,D,E,F)
Distributes and amplifies:
- two LTC inputs to four analog clock signal outputs
-four different time zones possible
(demultiplexed from Alpermann+Velte's MTD A,B,C,D,E,F)
Distributes and amplifies:
-one 10MHz continuous wave input (e.g. from RUB GPS 10MHz) to six 10 MHz continuous wave outputs
-output monitoring with programmable redundant change-over switcher
