Vaunix Technology Corp., a manufacturer of USB controlled and powered test equipment, recently added a programmable digital attenuator to their LDA family of PC-driven Lab Bricks, the LDA-602EH.
The LDA-602EH has a large attenuation range of 120 dB with an exceptional 0.1 dB step size, allowing for both precision and accuracy during fading tests or device characterizations. This attenuator also features a fast 15 µs switching speed, an operating temperature from -30°C to 50°C, a maximum RF input of +28 dBm, and is priced at $875. The LDA602-EH operates with a low insertion loss of 9 dB to 6 GHz, an input IP3 of +55 dBm and a typical VSWR of 1.3:1.
Easily programmed for ATE applications, the LDA digital attenuators are a cost effective solution whether you are in engineering, the production test lab, or in the field. Units are ROHS compliant and can be used with any PC or laptop computer with USB 2.0 port (or powered USB hub) and Windows operating system. Lab Brick Signal Generators are provided with easy to use Lab Brick GUI software, 32 and 64 bit API DLL files, LabVIEW and Linux compatible drivers.
