Key Features of Keysight J7211A/B/C Attenuation Control Unit
The J7211A/B/C attenuation control units are standalone portable instruments that offer a user-
defined attenuation sweep function. This feature allows setting of desired attenuation range, step
size, number of cycles and attenuation configuration based on user application’s requirements.
J7211A/B/C are designed in a way which make them suitable for benchtop and ATE testing for
applications such as base station transceivers (BTS) test, WLAN, WIMAX™, MIMO and WCDMA.
Exceptional insertion loss repeatability and excellent attenuation accuracy and flatness over 5
million cycles operating life ensure precise measurements and reduce calibration intervals
reducing cost of test.
The features and functions of attenuation control units are easily accessible via front panel using
soft keys and the rotary knob. J7211A/B/C are LXI Class C compliant instruments which provides
GPIB, USB and LAN connectivity for easy remote control and triggering through a full- featured
graphical web interface. This attenuation control units also allow relative attenuation to any values
by selecting relative attenuation step function. Calibration data is stored in the instrument’s
memory for fast, simple and easy retrieval.
