r&s®xk2500l hf transceiver | 概览 -九游官网下载

the r&s^®xk2500l 500 w hf transceiver is available as a desktop version or as a sturdy rackmount for the 1.5 mhz to 30 mhz frequency range. it can be operated locally as well as remotely via an integrated, multistandard serial interface. for the local mode, a user-friendly, large backlit lcd display is provided on the front panel of the r&s^®gx2900l receiver/exciter, delivering a bright picture together with function-assigned softkeys. these control elements allow programming of approx. 400 channels as well as the complete operation and configuration of the transceiver via user-specific menus (incorporated as firmware).

all settings of the transceiver can be made via the rs-232-c/rs-485 interface (integrated and configurable). the following remote control units can be used:

• r&s^®gp2000 remote control
• r&s^®gb2000 remote control unit
• terminal
• pc with rs-232-c/rs-485 interface

two units can be simultaneously connected. the associated software (r&s^®xk2000s) is supplied on a cd-rom. the basic r&s^®xk2500l model consists of the following:

• r&s^®gx2900l receiver/exciter
• r&s^®vk2500 power amplifier
• r&s^®in4150/in4190 ac power supply

the r&s^®gx2900l comes with free slots at the rear to take up user-specific interface options for matching the system or user units. atus are connected to the rear r&s^®vk2500 interface.

for ac operation of the transceiver, the r&s^®in4150 ac power supply is used, which can be set to different input voltages as well as to single- or three-phase networks. moreover, a 24 v standby battery can be connected to the r&s^®in4150 for interrupt-free operation of the transceiver at reduced rf power (100 w) in the event of a power failure.

if the transceivers are operated in data mode, i.e. continuously at full transmit power, an integrated blower system, which is switched on automatically when required, ensures continuous trouble-free operation of the transceivers without overheating.

the r&s^®gvxx, r&s^®fk21xx, and r&s^®gs21xx interface options that are plugged in at the rear of the r&s^®gx2900l receiver/exciter allow easy connection or matching to external options such as a system processor (pc), hf modem, detached duplex or emergency receiver (gmdss). up to four interface options can be inserted into the free slots at the rear.

the standard spacing between the r&s^®gxxx, r&s^®vkxx, and r&s^®inxx units is determined by the internal interconnecting cables. the spacing is 5 m between the r&s^®gx2900l and r&s^®vk2500/2900 and 1 m between the r&s^®vkxx and r&s^®in4150/4190.
