Setting the Deviation and Balance | RF-Link Technology NL6000

∙Enter the active channel assignment for the radio. The value must be a number in the range 01 64.

∙Press ESC to return to the Main Menu.

4.Select Diagnostics ä Transmit Continuous Random Data.

5.Set the power value as follows:

∙Select Power from the Diagnostics menu.

∙While watching the power gauge, change the power value and check the gauge to see that the power value registers correctly. The value must be a number in the range 0 1023.

∙Press ESC to return to the Diagnostics menu.

6.Set the frequency trim as follows:

∙Select Frequency Trim from the Diagnostics menu.

∙While watching the Frequency Error gauge on the IFR, change the frequency trim value on the Frequency Trim window until the needle on the gauge is centered.

7.Select None from the Diagnostics menu to stop the data transmission

Setting the Deviation and Balance

To properly set the deviation and balance, you must perform the following procedure twice once near each edge of the transmit frequency band. In this procedure, an edge is defined as approximately 2.5 MHz from one end of the band range.

1.From the terminal emulator, enter programming mode.

2.Select one edge of the transmit frequency as follows:

∙Select Radio Ä Transmit Frequency for Active Channel.

∙Enter a frequency that is on one edge of the frequency for the active radio channel. The value must be a number in the format nnn.nnnn.

∙Press ESC to return to the Main Menu.

3.Set the IFR to receive at the transmit frequency you set in Step 2.

4.Select Diagnostics ä Transmit 100 Hz Square Wave.

5.Set the balance value as follows:

∙Select Balance from the Diagnostics menu.

∙While watching the square wave on the IFR, enter 1-Increase Balance 0.125 dB or 2-Decrease Balance 0.125 dB until the corners of the wave are at a 90 angle.

∙Press ESC to return to the Diagnostics menu.

6.Select None from the Diagnostics menu to stop the square wave.

7.Select Transmit Continuous Random Data from the Diagnostics menu.
