3. The RF signal source is set to LF-4400MHz, frequency sweep output, step 100K, frequency sweep time 10ms, power is set to 0dBm output; the spectrum analyzer uses the maximum hold mode.
4. The RF signal source is set to LF-4400MHz, frequency sweep output, step 100K, frequency sweep time 10ms, power is set to -10dBm output; the spectrum analyzer is set to the maximum hold mode.
5. The RF signal source is set to LF-4400MHz, frequency sweep output, step 100K, frequency sweep time 10ms, power is set to -15dBm output; the spectrum analyzer uses the maximum hold mode.

Operation Manual:

1. Hardware Picture

2. Hardware Panel Operation Instructions
Refer to the above picture for a brief explanation:
1) Power supply: Connect the power supply (computer) through TYPE-C
2) Power switch: next to the USB, switch to the left to turn on, switch to the right to turn off.
3) Press the "OK S3" key to start the frequency sweep and stop the frequency sweep.
4) Press S1 to change the cursor position(move to the left);
Press S5 to change the cursor position (move to the right);
Press S2 to change the data of cursor position (plus);
Press S4 to change the data of the cursor position (subtract);
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.
OLED operation is realized through 5 buttons. The left / right buttons are used to move the cursor. When a certain bit is reversed, adjust the plus / minus buttons to modify the current bit. After pressing the OK button, the data is updated and stored into EEPROM.

PC Software Operating Instructions:
1) Connect the hardware first, then turn on the host computer, set the baud rate to 115200, and find the corresponding serial port.
Serial port number query method: right-click "My Computer" and select Manage. Open the computer management, open the device manager, click "port (COM and LPT)", you can view the port number.
Serial driver: PL2303SAusb driver collection xpwin7.rar, install this driver.

Software Interface Diagram:
1) Open the "RF signal source control software" software, pop up the host computer interface, note that "static.ini" is not a virus file, it is used to save the value set by the host computer, and the "RF signal source control software" file In the same folder.
2) The host computer interface can set the start frequency, end frequency, frequency sweep step, step time, power setting, set all parameters with one key, run the frequency sweep, and stop the frequency sweep. Note that when the start frequency is the same as the end frequency, it is the point frequency output, or the sweep frequency is in the stopped state, and the output point frequency signal frequency is the start frequency value.
