JFW’s model 50PA-1019-XX is their latest programmable attenuator assembly designed for 5G wireless testing. It is an expandable design that can be configured to have up to 16 individually controlled attenuators. The test system has the following features:
- Operates 100 MHz to 40 GHz
- 0 to 62 dB by 1 dB step attenuators
- Up to 16 attenuators
- 2.92 mm female RF connectors
- Ethernet, Serial, and Manual controls
- Uses DHCP for easy network setup
- 19 inch rack mountable chassis
Model 50PA-1019-XX is a 19 inch rack mount attenuator assembly containing 50 Ohm solid-state step attenuators. The number of attenuators can be selected from 1 to 16 attenuators. The attenuators have an attenuation range of 0 to 62dB by 1dB steps and operate at 100 MHz to 40 GHz. The attenuators can be controlled manually or remotely. It is available with 2.92 mm female 50 Ohm coaxial RF connectors. The RF connectors are located on the rear panel. The RF connectors are labeled as Input and Output, but the attenuators are bi-directional.
The manual control menu allows you to set/read an attenuator, fade an attenuator, or perform a handover using two attenuators.
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.
The firmware manual for JFW’s latest generation firmware is available for download. This manual lists all of their remote commands with command syntax and examples. JFW’s 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.
