Vaunix Technology Corp. announced the release of the first two in a series of their Lab Brick™ devices available with Ethernet control. The two new multiport Lab Brick Digital Attenuators are the four-port LDA-802Q, and the eight-port LDA 802-8, each operating from 200 MHz to 8 GHz for a variety of L-, S-, and C-Band applications that require the need for single shot or repeating attenuation ramps. 

These solid-state, rugged, yet low-cost 50 Ω step attenuators are bi-directional and offer high dynamic range of 120 dB. They also feature an impressive, ultra-fine step size of 0.1 dB for ultimate signal attenuation control. 

These portable and programmable RF/microwave test devices have been designed to suit high speed MIMO test platforms as they are easily programmed for fixed attenuation or swept attenuation ramps/fading profiles directly from the included graphical user interface. Additional testing applications include Wi-Fi 6E, Wi-Fi, 3G, 4G, 5G, LTE and DVB systems and microwave radio simulators. 

Test technicians wishing to develop their own interface, can utilize Vaunix’s included LabVIEW drivers, Windows API DLL files, Linux drivers, macOS SDK examples and more. 

These portable, hand-held units can also be packaged as a single rack unit for ATE stands. Other custom engineering of electrical and mechanical specifications is also available.
