Vaunix have recently added a new 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 characterisations.
The LDA-602EH also features a fast 15 us switching speed, an operating temperature from -30oC to 50oC, and a maximum RF input of +28 dBm. This attenuator 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, 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.
