NEW  6G Digital Programmable Attenuator 60DB Step 0.25DB OLED Display CNC ATT-6000V2.0       Numerical control radiofrequency attenuator ( LF-6GHZ ) ATT-6000V2.0 1. Product application: The digital attenuator can be used without interrupting the circuit.0.25dBstep The signal level of the form adjusting circuit can also be used as the internal attenuator of the instrument and the power level in the test system. It has the characteristics of small volume, high precision, stable and reliable and so on.OLEDDisplay attenuation,CNCAluminum alloy shell. 1Working frequency:LF-6GHz 2.The attenuation adjustment range:0-60dB (2GHZ,2GThe above error is specific to the measured index) 3.Attenuating step:0.25(dB) 4.Insertion loss: ≤1.5dB(high frequency end insertion loss is larger) 5.Bobbi: ≤1.4 6.Attenuation accuracy:±0.25dB Max 7.Rated power: ≤1W 8.Connector form:SMA(the female head, the inner hole of the outer snail) 9.Temperature range:-10Centigrade+50Centigrade (operation) , -40Centigrade+70Centigrade (not running) 10.Shape size:55X40X16.5mm(Not containingSMAInterface protruding part,SMAProtruding part9mm) 11.Weight:57g 12.Input and output impedance:50Ohm 2. The product's physical map:     3, panel and Operation Description: 1Power supply: throughmicro-USBConnect the power supply (signal source, computer, charging treasure, etc.). 2Power switch:USBNext, switch left to the left and turn right, then turn right. 3SMA1 radio frequency input, SMA2 radio frequency output. 4After opening the machine, press “ determineS3” key initialization power meter. 5ButtonS1Change the position of the cursor(Left shift) KeyS5Change the position of the cursor(Right shift) KeyS2Adding data to the cursor bit KeyS4Reducing the cursor bit data After entering the system, the cursor represents the selected digit. The upper and lower buttons can modify the numeric value of the selected digit. When the cursor is in the last (or first) position of the option, press the right button (or left key) to switch the options. When the parameters are set, press the middle key to make the settings effective.     4.
