Description
Model 50PA-1205 is an 8 x 1 LC handover test system operating 30-6000MHz. The unit consists of eight programmable attenuators (i.e. 8 ATTEN ports) that are combined together by an 8way splitter/combiner to a single common port (i.e. COM port). Each of the attenuators has attenuation range 0-95dB by 1dB steps. The unit has insertion loss paths (i.e. any ATTEN port to the COM port). It also has isolation paths (i.e. any ATTEN port to any other ATTEN port).
Remote Command Set
All remote command syntax and examples can be found in our firmware manual. 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.
Manual Attenuator Control
The manual control menu allows you to set/read an attenuator, fade an attenuator, or perform a handover using two attenuators.
Remote Attenuator Control
This attenuator assembly 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. All new test systems are shipped from the factory in DHCP 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.
