Note : Your request will be directed to JFW Industries.

The 75BA-004-95-127 from JFW Industries is a Benchtop Attenuator Assembly with two attenuators that operate from 5 to 2150 MHz. Each attenuator has an attenuation range from 0 to 95 dB (1 dB steps) with an insertion loss of less than 6 dB. They can handle up to +25 dBm of average input power, have a VSWR of less than 2:1, and a switching speed of 2 µs. The attenuators can be controlled manually or remotely. They are matched to 75 Ohms and have F-Type Female connectors on the front panel.

The attenuators can be manually controlled by a Momentary Lever Actuator Switch with a 7-Segment LED Displays. They can also be remotely controlled via an Ethernet connection or a serial connection (RS-232). The network interface can be set in either DHCP mode or Fixed Address mode. The attenuator operates bi-directionally.
