The TSEP Step Attenuator was developed to provide HF signals with any configurable attenuation, the temporal course of which can be adjusted. The TSEP Step Attenuator contains up to 3 channels and each of these channels can be individually attenuated. These different attenuations can be switched independently. Each channel can be supplied with an attenuation of 0 to 31.5 dB, with a step width of 0.5 dB and an accuracy of 0.1 dB.
The TSEP Step Attenuator can be controlled directly via USB from a control computer (online mode) or operated offline. The attenuation curves are controlled and defined via a separate application. With the help of the application, the individual damping curves can be entered, visualized and changed. For this purpose, the individual values can be freely entered or generated via predefined functions (e.g. sinusoidal curve). All damping curves are saved as XML files and can be loaded if required. The application is currently available for Windows (32/64-bit). In offline mode, the previously configured damping curves can be run individually for each channel. The resolution is 0.5 seconds and the runtime can be up to 24 hours.
