Description
Model 75BA-004-95-127 is a 75 Ohm benchtop attenuator assembly containing two solid-state step attenuators. The attenuators have an attenuation range of 0 to 95dB by 1dB steps and operate from 5 MHz to 2150 GHz. The attenuators can be controlled manually or remotely. Its current attenuation setting is displayed on the front panel. It is available with F female 75 Ohm RF connectors. The RF connectors are located on the front panel. We label the RF connectors as Input and Output as a naming convention only. The attenuator operates bi-directionally.
Manual Attenuator Control
Two manual lever switches are on the front panel located under their corresponding attenuation display. The levers can be used to adjust the attenuation up/down. The levers are momentary type switches so you can “tap to step” or “hold to jog”. As you manually change the attenuation setting of the attenuator you will see its displayed dB value change simultaneously. You will also view any changes that a remotely connected user makes to the dB setting of the attenuator.
Remote Attenuator Control
This attenuator assembly can be remotely controlled via an Ethernet connection or a serial connection (i.e. RS-232). The network interface can be set in either DHCP mode or Fixed Address mode. We ship all new test systems 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.
