OVERVIEW
The Ranatec Digital Attenuator Box 100 MHz – 8 GHz, 1 U, 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. It offers very good attenuation accuracy, high dynamic range and speed.
The high performance of the Digital Attenuator Box 100 MHz – 8 GHz, 1 U, 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.
CONTROL OPTIONS
1) Web-interface, for manual operations
2) Textual (SCPI-like) API
3) Binary API
APPLICATION
The Attenuator Box 100 MHz – 8 GHz, 1 U, 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 Bluetoth devices:
• During all phases of product development
• For (pre-)conformance testing/homologation
• Production testing / Quality assurance
