TB8100 Calibration Kit User’s Manual Calibrating the Exciter 15
Setup
To calibrate the FCL
1. Ensure that the Calibration Kit PC is connected to the reciter.
2. Select the Reciter Calibration tab, and double-click FCL Calibration. The
FCL Calibration Wizard appears.
3. Attach an appropriate Load and Modulation meter to the PA or exciter
output, set the meter to measure the RMS deviation, and then click Next.
(If you are using a PA, it will now transmit.)
4. Insert the tuning tool into the correct exciter VCO tuning hole (see below)
and adjust the trimmer until the actual band matches the desired band. The
bands turn green. Click Next.
5. Use the slider to adjust the deviation at 1 kHz until it is 2107 Hz RMS
(3 kHz peak).
6. Select the 30 Hz Modulation Test and adjust the deviation at 30 Hz until it
is 2107 Hz
RMS (3 kHz peak).
7. Repeat steps 5 and 6 until the deviation is 2107 Hz RMS at both 1 kHz and
30 Hz.
8. Click Finish. (If you are using a PA, it will now stop transmitting.)
When you have finished calibrating the FCL, the icon on the Reciter
Calibration tab indicates that this task is complete.
You will now need to calibrate the VCO.
