the r&s®ts-ptrf is an accessory module for routing digital control lines of the r&s®ts-pio3b digital i/o module to the front panel of the r&s®compacttsvp or r&s®powertsvp. in both instruments, the module is connected as a switching and distribution module in front of an r&s®ts-pio3b or an r&s®ts-ptr signal transmission module and offers a variety of ways to route signals.
the r&s®ts-pio3b digital i/o module is designed as a universal coil driver. in conjunction with the r&s®ts-ptrf option, any number of external relays or built-in switching relays – particularly relays for rf signal routing – can be connected in a standardized manner. in this case, the r&s®ts-ptrf module is used as the port distributor.
local 5 v/ 12 v supply voltagesthe r&s®ts-ptrf module receives a 12 v supply voltage from the r&s®ts-pio3b digital i/o module or from the passive r&s®ts-ptr signal transmission module. this voltage is converted to 5 v directly on the front module and is made available externally and at all ports from p0 to p7 on connectors x33 to x40. the likewise available 12 v supply voltage is protected on the r&s®ts-pio3b or on the r&s®ts-ptr via safety fuses. the 5 v supply voltage is not fuse-protected, but it is short-circuit-proof. the converter can deliver an output current of max. 2 a at 5 v.
analog bus accessthe r&s®ts-ptrf provides a connector to the analog bus. when the module is used in slots 3 to 14 in the r&s®compacttsvp or in slots 1 to 14 in the r&s®powertsvp, contact is established between connector x30 and the analog bus. the eight lines of the analog bus are routed to connector x32.
distribution of digital i/o portsfor each open drain i/o port (0 to 7) of an attached r&s®ts-pio3b, the r&s®ts-ptrf provides contact to one plug-in connector from x33 to x40. furthermore, each open drain i/o port of the r&s®ts-pio3b can optionally be led out to the front panel via jumpers.
additional simple analog measurement channelsthe eight analog inputs of the r&s®ts-pio3b module can optionally be led out to the front panel via jumpers. furthermore, one analog line each is routed to plug-in connectors x33 to x40.
