For more information contact Dow-Key's technical sales staff. Physical Relay Type: * : 'Y' for only 40 GHz switches, or else 'leave it blank' n : n number of switches (max. 4 switches) SP6T =6 SP10T =10 DPDT (transfer) = X ** : ENET or GPIB Note 1: For LNET option contact factory for part number. Note 2: For redundant power supplies, ask for 5148-Series Description Model 4104 is a bidirectional coaxial switching system with switches mounted independently on the rear panel in 1U chassis and are controlled separately; hence it is known as a blocking configuration. Normally Open Multiposition or Latching Transfer Contact Material: Beryllium copper, gold-plated I/O Connector Type: SMA Female Dimensions: 19" wide standard rack mount 1U maximum height (1.75") * 15" maximum depth Front Panel Color: Gray Weight (nominal): 14 lbs * Unit with SP10T switches is 2U in height partially (as shown in above photo) Environment 85-264 VAC, 47-63 Hz, 3-6 A, 275 W (max) Standard AC grounded power cable (removable, IEC 320 C19 to NEMA 5-15P) Fuse/Breaker: Externally accessible/replaceable Storage Temperature: -20 °C to +70 °C Operating Temperature: 0 °C to +60 °C Control Interfaces Local control (on the front panel): >> The system is equipped with manual control via a 4-line LCD (4x40) display and keypad control (except for the LNET version). Model 4104 is offered with switches that either operate between DC -18 GHz or between DC-40 GHz (refer to RF data page). The system can support up to (4) switches at the maximum and is available with three different types of switches: DPDT (transfer switch), SP6T, and SP10T. If a more flexible capability is needed and different type of switches are required, refer to Dow-Key's "Build You Own Matrix" data sheet, where two additional solutions are offered: the Silver Package and the Gold Package. Remote Control (on the rear panel): All versions are equipped with >> RS-232 (DP9 female) connector with Baud Rate 9600 bps >> CANBus (DP9 male) used for programming the unit >> SCPI commands ENET or LNET (Options): >> TCP/IP control via 802.3 protocol (Ethernet) >> Supports 10BASE-T/100BASE-T via RJ-45 connector. >> LXI style remote access via any web browser (only LNET version) GPIB (Option): >> IEEE-488 with 26 pin female connector v2.0 03/09 www.dowkey.com [email protected] 4104 Model Electromechanical - RF Switching System RF Characteristics Impedance: Operating Frequency: Switching Speed: Operating Life: 50 Ohms DC-18 GHz or DC-40 GHz 20 ms 1,000,000 cycles (Cold Switching) Depending on the type of system, different coaxial switches are used.
