Output Power: -1dBm (W) @ 150MHZ (test power absolute value) about 1 mW
Features:
1. Simple RF signal source signal generator
2. Core component: avr mega8 microcontroller, cost-effective single chip, is a low-profile version of the commonly used m16. There is a 2.56v voltage regulator in the peripheral ADC, which other mid-range microcontrollers do not have.
3. Adf4351: Traditional VCO + PLL + 6 series high-speed bistable circuit. The output is obtained by frequency division, and the output is a square waves. The amplitude of the fundamental wave does not change much.
4. This product provides a signal source for the AC channel of the device under test and analyzes the frequency-amplitude characteristics of the AC channel. Please pay attention to the impedance of the measuring equipment.
Package Include:
1x RF Signal Generator
1x Cable
1x Antenna
More Details:
1. The operating keyboard of this product has 15 ppt keys, 0~9 numeric keys, 10 "++" and "-" keys to adjust the use frequency, and also produce the emission output behavior. Short press "++" or "-" key step will add 1khz or minus 1khz to the original frequency output. Pressing "++" or "-" for more than 1 second will result in continuous or continuous subtraction scanning mode. The step is 1kHz at 35kHz to 138MHz; 138kHz at 138MHz. The step is 10khz at ~550mhz and 100khz at 550mhz~4000mhz. To end the scan, just press the "++" "-" button or the "OK" button. The "OK" button is the output control button. Press again to stop transmission, the emission behavior caused by "++" or "-" needs to press "OK" twice to end the transmission, the product will display ">>" in the upper right corner. When the output emission behavior occurs, the "C" key will terminate the transmission and the frequency is zero.
2. Step "<>" key, used for continuous addition and continuous subtraction scanning mode to facilitate adjustment, cycle selection step "1K", "10K", "100K", "1M".
3. By pressing the "<>" button, the new bottom LCD1602 defaults to "<1k>" step indication when it is powered on. Four types of step states can be cycled.
