In order to apply RF signals with any configurable attenuation whose time profile is adjustable, the USB TSEP step attenuator has been developed.

The "USB Step Attenuator" contains 3 channels, each of these channels can be individually applied to a configurable attenuation. These different attenuations can be switched independently. Each channel can be with an attenuation of 0 to 31.5 dB, with a step size of 0.5 dB is applied. The accuracy is 0.1 dB.

The "USB Step Attenuator" can be powered by the included 12V power supply. Alternatively, can be fed via external 12 V banana plug.

The DC voltage present amount of signal that is measured using the internal microcontroller. The visualization of the three voltage ranges using LEDs on the front panel.

The operation of "USB Step Attenuators" via dial and LCD display. In addition, the "USB Step Attenuator" can be directly controlled by a control computer (online mode) or Offline operate. In offline mode, the previously configured damping curves can be worn individually for each channel. The resolution is here at 0.5 sec, the running time can be up to 24 hours.

The control of the "USB Step Attenuators" via USB. With the help of the application, the individual attenuation curves can be entered and changed visualized. All attenuation curves are saved as XML files and can be loaded on demand.
