r&s®xk2900l hf transceiver | 概览 -九游官网下载

the r&s^®xk2900l 1000 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 lc 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 processor
• 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^®series 2000s) is supplied on a cd-rom.

the basic r&s^®xk2900l model consists of the following:

• r&s^®gx2900l receiver/exciter
• r&s^®vk2900 power amplifier
• r&s^®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.

for ac operation of the transceiver, the r&s^®in4190 ac power supply is used, which can be set to different input voltages as well as to single- or threephase networks. moreover, a 24 v standby battery can be connected to the r&s^®in4190, 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, hf modem, detached duplex or emergency receiver (gmdss). up to four options can be inserted into the free slots at the rear.

the 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^®in4190.
