The 4-channel J7204A/B and 5-channel J7205A/B attenuation control units feature excellent 0.03 dB insertion loss repeatability. Attenuation accuracy and flatness provides the much-needed test accuracy and reliability for receiver sensitivity test, or fading test. In addition, the long operating life of 5 million cycles and the ability to test multiple DUTs (4 or 5 devices) provides a lower cost of test and ownership.
The J7204A/B and J7205A/B multi-channel attenuation control units provide calibration data (as an option) to allow you to do a correction on the attenuation value and provides you with the exact input power level for each DUT. In addition to the superb repeatability of 0.03 dB and excellent attenuation accuracy and flatness, this method ensures the utmost accuracy and stability of the input power when performing receiver sensitivity test.
Designed for a standard full rack, 2-unit-high form factor, these attenuation units allow flexibility in control, operation and remote triggering through LAN, GPIB with multiple programming language supportability.
