Digital Step Attenuator
Ranatec offers Digital Step Attenuator systems and modules that covers all mobile frequency bands and gives a calibrated attenuation range of more than 90 dB in steps of 0.25 dB, and offers both serial and parallel control logic.
Ranatec’s digital attenuators are used to accurately and reliably set RF-signal levels, either as an integral part of an in-service RF-solution or as part of a wireless test automation system. Applications span multiple industries and technologies.
Ranatec has developed a range of wireless test automation products, enabling accurate and efficient test and verification of RF and microwave subsystems, products and solutions. The Ranatec test automation procuct range contains both general pupose instruments as well as solutions tailored to customer specific demands and are used for design validation and verification, homologation and certification as well as production testing and in-service monitoring.

Overview
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.
Application
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:
- During all phases of product development
- For (pre-)conformance testing/homologation
- Production testing / Quality assurance
Control Options
- Web-interface, for manual operations
- Textual (SCPI-like) API
- Binary API
