ADF4351-VFO Source V1.03 Signal Generator 35MHz-4400MHz Simple Signal Source Module with Mechanical Rotary Encoder
Specification:
- Power supply voltage: DC4.5V - 5.5V (Please note that this device does not have a built-in voltage regulator unit, so do not supply power beyond the voltage range.)
- Standby current: <25mA
- Transmitting current: <150mA
- Output impedance: 50ohms
- Output frequency range: 35MHz - 4000MHz
- Output step: 1kHz - 8kHz
- Output power: -1dBm (W) at 150MHzm, about 1mW
- Core component: for AVR Mega8 micro-computer, ADF4351 PLL oscillator
Instruction:
- This product's operating keyboard consists of 14 PPT keys, including 10 numeric keys from 0 to 9. The "++" and "--" keys are used to adjust the frequency and also generate emission output. Short press the "++" or "--" keys to increase or decrease 1kHz in the original frequency output. Press and hold the "++" or "--" keys for more than 1 second to display a continuous increase or decrease scanning mode. The step is 1kHz for 35MHz-138MHz; The step frequency is 10kHz for 138MHz-550MHz; The step frequency is 100kHz for 550MHz-4000MHz. To end the scan, simply press the "++", "--", or "OK" keys once. The "OK" key is an output control key that emits when pressed once and stops when pressed again. The emission behavior caused by "++" or "--" requires pressing "OK" twice to end. When this product has output emission behavior, a ">>" will appear in the upper right corner of the display screen, and the "C" key will end the emission and reset the frequency to zero.
- The step key is replaced by a down press mechanical rotary encoder and is used for adjusting the scanning mode of continuous addition and subtraction. Cyclically select step sizes of "1K", "10K", "100K", and "1M", inheriting all key operations from V1.02 version. Rotary encoder arrangement: counterclockwise rotation for decreasing operation, clockwise rotation for increasing operation, press down instead of the original keyboard's "<>" step selection key, which is more convenient.
Note:
- The EEPROM of this product will record the output frequency displayed when the "OK" button was last pressed, and when powered on again, it will default to directly transmit the output frequency recorded by the EEPROM.
Package Included:
- 1 x Signal Source Module
