Mini-Circuits’ RCDAT-40G-30 is a precision programmable attenuator covering an extremely wide bandwidth, from 0.1 to 40 GHz. Its unique design allows attenuation settings to be programmed from 0 to 30 dB, in 1.0 dB steps (Mode 1) and 0 to 29 dB in 0.5 dB steps (Mode 2) with monotonic attenuation change per dB, even at the highest frequencies and attenuation settings.
The attenuator can be controlled via USB or Ethernet, allowing control directly from a PC, or remotely over a network. Full software support is provided, including our user-friendly GUI application for Windows and a full API with programming instructions for Windows and Linux environments (both 32-bit and 64-bit systems).
This model also includes Mini-Circuits’ novel dynamic addressing daisy-chaining interface which allows multiple RCDAT-40G-30 attenuators to be connected together into a Master / Slave chain, with independent control of each attenuator channel through the single USB or Ethernet connection of the master unit.
