JFW Industries 4Port 50PMA-083 Programmable Attenuator Assembly 500 MHz-6000 MHz

Description: JFW Industries 50PMA-083 Programmable Attenuator Assembly 500 MHz-6000 MHz Model 50PMA-083 is a 4 port transceiver test system operating 500-6000 MHz in a 19 inch rack mount enclosure. It has a mesh configuration with full fan-out. With this type of construction there is a path between every pair of ports. There are 6 paths in the 4 port mesh and every path has its own individually controlled programmable attenuator. The attenuators have attenuation range 0-95 x 1dB steps. To check the attenuation settings of all attenuators use the RAP (read all paths) command. The test system will respond back with a listing of all 6 path attenuation settings. Radio to Radio Testing Full fan-out mesh transceiver test systems can be used to simulate static or dynamic environments for testing radio to radio communication. All paths between radios have their own individually controlled step attenuator. The signal level between radios can be changed up/down over the full attenuation range of the step attenuators. The attenuators can be set to static values using the set attenuator remote command or can be faded over a time interval using the fade attenuator remote command. Default Settings Transceiver test systems with Ethernet/RS-232 remote control are shipped from JFW with the network interface set to DHCP mode and the serial baud rate set at 57600. These settings can be changed manually with the keypad or remotely using the NET or SERIAL remote commands. The display on the front panel shows the current settings for network mode, IP address and baud rate. Remote Attenuator Control The transceiver test system can be remotely controlled via an Ethernet connection or a serial connection (i.e. RS-232). The network settings can be changed manually with the keypad or remotely using the NET remote command. The network interface can be set to either DHCP mode or Fixed Address mode. A RS-232 connection to the test system is made using a null modem type serial cable. Baud rates up to 155200 baud are available. The baud rate can be changed manually with the keypad or remotely with the SERIAL remote command. Remote Command Set The firmware manual for our latest generation firmware is available for download. This manual lists all of our remote commands with command syntax and examples. Our firmware uses simple ASCII formatted remote commands. If you are connected to a JFW test system and send the HELP command, it will respond back with a list of all remote commands for that specific test system.
