The RF2025 Attenuator Box is a high performance, digitally controlled, 4-channel RF attenuator system. It is intended for any automated RF testing where high accuracy signal power control is needed. The RF2025 offers very good attenuation accuracy, high dynamic range and speed.
The high performance of the attenuator box is obtained through a high precision attenuator design, along with extensive factory calibration procedures. Although the nominal setting is done with a 1 dB granularity, the actual attenuation is fed back from the attenuator. For the frequency range up to 6 GHz, this yields knowledge of the actual attenuation within +/-0.25 dB.
The RF2025 is intended for any testing where accurate RF power control is needed over a wide dynamic range. Typical applications include transmitter, receiver as well as system level testing of mobile, WLAN and Bluetooth devices:
