New 6GHz OLED Display Digital Programmable Attenuator 60DB Step 0.25DB RF Module

Description

New 6GHz OLED Display Digital Programmable Attenuator 30DB Step 0.25DB RF Module
Description
First, the product application:
The digital attenuator can adjust the signal level of the circuit in the form of 0.25dB stepping without interrupting the circuit.
It can also be used as the in-machine attenuator of the instrument and equipment to adjust the power level in the test system, ,
High precision, stable and reliable features, the use of OLED display attenuation, CNC aluminum alloy shell.
1, the operating frequency: LF-6GHz
2, attenuation adjustment range: 0-60dB (2GHZ, 2G above the specific error measured indicators)
3, attenuation step: 0.25 (dB)
4, insertion loss: ≤ 1.5dB (high-frequency side of the insertion will be larger)
5, standing wave ratio: ≤ 1.4
6. attenuation accuracy: ± 0.25dB Max
7. Rated power: ≤ 1W
8. Connector form: SMA (female, female screw hole)
9. Temperature range: -10 ℃ ~ +50 ℃ (running), -40 ℃ ~ +70 ℃ (not running)
10. Dimension: 55X40X16.5mm (excluding SMA interface protruding part, SMA protruding part 9mm)
11. Weight: 57g
12. Input and output impedance: 50 ohms
Third, the panel and operating instructions:
1, power supply: through the micro-USB power supply (signal source, computer, charge Po, etc.).
2, power switch: USB next to the switch to the left to start the machine, right to turn off the machine.
3, SMA1 RF input, SMA2 RF output.
4, boot, press the "OK S3" button to initialize the power meter.
5, press the key S1 to change the cursor position (left)
Button S5 to change the position of the cursor (right shift)
Press key S2 to change the cursor bit data plus
The key S4 changes the cursor bit data minus
After entering the system, the cursor indicates the selected digit, then the upper and lower keys can modify the value of the selected digit.
When the cursor is at the last bit (or first digit) of the selected item, press the right button (or left) to toggle the selected item.
When the parameter is set, press the middle key to make the setting take effect.
Fourth, the communication interface can be secondary development
1, USB interface (power supply, you can communicate via USB)
2, serial communication protocol analysis
CNC attenuator ATT-6000 protocol overall structure using the command line mode,
the communication baud rate of 115200bps, issued by the PC command,
the machine parsing execution, and then return the results to the PC,
the command is limited to lowercase letters a ~ z, ~ 9,
the end of each command symbol for the newline (hexadecimal expressed as "0x0a" or '/ n')
The communication command contains three types of commands: w command, r command.
rid command: read the version number
The machine returns the machine model, the machine returns the machine model,
the result is: ATT-6000 (Note return the machine model data format is ASCII character format, pay attention to followed by a new line "0x0a" or "/ n").
wv0 command: set love love simply
Format: wv0xxxx + 0x0a, a total of 8 bytes;
Where "xxxx" is the attenuation value represented by four digits, such as:
wv01150 + 0x0a: indicates that the write attenuation is: 11.5DB (the maximum attenuation is: 0-6000, step 25)
Converted to hexadecimal: is 0X77 0X76 0X30 0X31 0X31 0X35 0X31 0X0a
Package Included:
1 x
New 6GHz OLED Display Digital Programmable Attenuator 60DB Step 0.25DB RF Module
