Attention:
1. This product uses local oscillator signal and external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. High-precision VCO sources can measure heterodyne signal frequencies very accurately. Due to the very large scanning range (35M-4400M), cost and other factors, there is no special detection circuit for external measurement signals, so the measurement amplitude may have errors. Therefore, the product increases the magnification and displacement parameters, and users can adjust the displayed waveform by themselves. The amplitude display is adjusted and calibrated.
2. Internal integrated lithium battery charging circuit. This product uses un38.3 certified batteries. 3.7V. 4000mAh, battery model 606090. By default, USB is used for charging.

35MHz-4000MHz Signal Source:
Specifications:
- Supply voltage: DC 4.5V-5.5V
- Standby current: <25mA
- Emission current: <150mA
- Output impedance: 50 ohms
- Output frequency range: 35MHz-4000MHz
- Output stepping: 1KHz-8KHz
- Output power: -1dBm (W) at 150MHZ (test power absolute value) about 1 mW

Features:
- Simple RF signal source signal generator
- Core components: avr mega8 microcontroller, cost-effective single-chip, is a low-profile version of the commonly used m16. There is a 2.56v regulated source in the peripheral ADC, which is not available in other mid-range microcontrollers.
- Adf4351: Traditional VCO+PLL+6 series high speed bistable circuit. The output is obtained by frequency division, and the output is a square wave. The amplitude of the fundamental wave does not change much.
- This product uses the single-chip microcomputer as the core, which greatly simplifies the design, shortens the development time and saves the cost. It provides the 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 device.

More Details:
This product operation keyboard has 15 ppt keys, 0~9 number keys, 10, "++" and "--" keys to adjust the frequency to use, also produces emission output behavior, short press "++" or "-- ”Key stepping adds 1khz or minus 1khz to the original frequency output. Pressing “++” or “--” for more than 1 second will result in a continuous or continuous subtraction scan mode. The step is 1khz at 35mhz~138mhz; 138mhz The step is 10khz at ~550mhz and 100khz at 550mhz~4000mhz. To end the scan, simply press the "++" "--" button or the "ok" button. The “ok” button is the output control button. Press it to launch. Press again to stop the transmission. The emission behavior caused by “++” or “--” needs to press “OK” twice to end the transmission. This product will display “>>” in the upper right corner of the display when there is output emission behavior. The “C” key will end the transmission and the frequency will be zero.

Stepping "< >" key, used for continuous plus continuous subtraction scan mode for easy adjustment, cycle selection step "1K", "10K", "100K", "1M", although not very useful, but also small Improvement, the original V1.01 board as long as the keyboard on the hole welding a 3.3k resistor and a PPT touch button to complete the improvement (compared to the keyboard board diagram, very simple), then, buy an AVR ISP download on Taobao The line downloads the bottom layer of the new MCU, and there is a new underlying source code and .hex file in the network disk. The fuse bit C9EF is not wrong.

The new bottom layer LCD1602 power-up defaults to the "<1k>" stepping indication by pressing the "<>" button. There are four types of stepping states that can be cycled.

Note:
- Please note that this machine does not have built-in voltage regulator unit, please keep it within the voltage range. Thank you!
