R&S^®GV400 Bus Coupler

For the configuration of complex radio systems with several (m) Control Units R&S GB406 and several (n) radios:

• Increased "fan-out" (increased number of loads)
• nterface load/system capacity: R&S GV400 models are available with 1, 2 or 3 bus converters, each converter with an interface capacity for 10 loads; thus up to 99 radios can be addressed and operated individually in a multiple system or simultaneously in broadcasting mode (address 00) using the corresponding number and models of R&S GV4001)
• Data conversions between the RS-232-C, RS-422 and RS-485 standards

Interface parameters (internally switchable):

• Level standards: V.10 (unbalanced)/V.11 (balanced)
• CTS and RTS signals with/without tristate
• Bit rate: 100 to 9600 bps (Bd)
• Operation/signal routing: depending on the required application the internally programmable switching matrix can be set to 4 possible operating modes which characterize the signal routing
• AF distribution: via separate voice switching system (audio matrix)
• PTT or other time-critical functions: their separate transmission and distribution (e.g. via the voice switching system) is recommended if unacceptably long transmission periods are calculated due to series transmission and wide number of radio units
• Indicators: LEDs indicate the active signals per converter
• Power supply: AC: 115 V/230 V +10/-15%, 50 Hz /60 Hz, 15 VA typ., <30 VA; DC: 24 V, typ. 500 mA (<1 A); 15 V to 32 V; AC/DC: automatic switchover with AC priority
• Dimensions (W x H x D), weight: 19" 1 HU rack plug-in; 483 mm x 44 mm x 329 mm (seated depth); 4 kg
