It can also be used as a built-in attenuator for instruments and equipment to adjust the power level in a test system. It is designed with small size, high precision, stability and reliability. Using OLED display attenuation, CNC aluminum alloy shell. Parameters: 1. Working frequency: LF-6GHz 2. Attenuation adjustment range: 0-60dB (for errors above 2GHZ and 2G, please refer to actual measurement index) 3. Attenuation step: 0.25 (dB) 4. Insertion loss: ≤1.5dB (the insertion loss at the high frequency end will be larger) 5. Standing wave ratio: ≤1.4 6. Attenuation accuracy: ±0.25dB Max 7. Rated power: ≤1W 8. Connector form: SMA (female head, external screw inner hole) 9. Temperature range: -10℃ to 50℃ (operation), -40℃ to 70℃ (not operation) 10. Dimensions: 55 x 40 x 16.5mm (excluding the size of the protruding part of the SMA interface, 9mm of the protruding part of the SMA) 11. Weight: 57g 12. Input & output impedance: 50 ohms Package Included: - 1 x Digital Programmable Attenuator Note: Other items pictured are not included, for demonstration purpose only. Panel and Operating Instructions: 1. Power supply: connect power supply via micro-USB (signal source, computer, power bank, etc.). 2. Power switch: next to the USB, switch to the left to turn on, turn to the right to turn off. 3. SMA1 RF input, SMA2 RF output. 4. After booting, press "OK S3" button to initialize the power meter. 5. Press S1 to change the position of the cursor (move to the left) Press S5 to change the cursor position (move right) Press S2 to change the data of cursor position (+) Press S4 to change the data of the cursor position (-) After entering the system, the cursor indicates the selected digit. At this time, the up and down buttons can be used to modify the value of the selected digit. When the cursor is at the last digit (or first digit) of the selected item, press the right button (or left button) to switch the selected item. After setting the parameters, press the middle OK key to make the setting effective. Communication Interface for Secondary Development: 1. USB interface (power supply port. Enable USB communication): The overall structure of the ATT-6000V2 protocol of the numerical control attenuator adopts the command line mode, the communication baud rate is 115200bps. The command is issued by a PC, the machine parses and executes it, and then returns the result to the PC. The command is limited to lowercase letters a ~ z, numbers 0 ~ 9, and the end symbol of each command is a newline character (hex represents "0x0a "Or '/ n') Communication commands include three types of commands: w command wv0 Command: Set output attenuation. The format is: wv0xxxx + 0x0a, a total of 8 bytes; where "xxxx" is the attenuation value represented by 4 numbers, for example: wv01150 n: indicates that the write attenuation is: 11.5DB (the maximum attenuation is: 0-6350 , With a step of 25). Converted to hexadecimal: 0X77 0X76 0X30 0X31 0X31 0X35 0X30 0X0a Versions after 2019 with a return value: "ok r n" text format value returned after receiving the correct data.Payment Terms 1.
