Single module software control instructions
1. Power setting adjustment, the left side displays the power value in dBm and W units respectively, and the right scroll bar can be dragged left and right to adjust the power.
2. The default frequency range of the first channel, Start Freq is the starting frequency, Stop Freq is the ending frequency, and the ending frequency must be greater than the starting frequency. The default frequency step is 1M, which can be adjusted accurately.
3. The frequency range setting of the second channel, the starting frequency of the second channel must be greater than the ending frequency of the first channel.
4. The frequency range setting of the third channel, the starting frequency of the third channel must be greater than the ending frequency of the second channel.
5. The function is the same as above, which is the frequency range setting of the fourth channel.
6. The power amplifier module switch setting. ON is turned on, and OFF is turned off the power amplifier.
7. Working status display:
Out Power: output power, the real-time power of the current module when it is working normally.
Temperature: module temperature.
Voltage: module supply voltage.
Current: module current.
VSWR: standing wave state.
8. Serial port settings, RS485 communication interface. Select the serial port number in the drop-down list box, Open to open, Close to close.
9. Frequency channel selection box, a total of 4 channels are available.
10. Module address code query and setting.
11. Query or set parameters, Inquiry is to query parameters, Set is to apply all modified parameters.
12. Display information feedback when querying or setting parameters.
