    DTUTT1K2HP1D ELETTRONICA 6. Equipment Quick Reference 6.1 Exciter (DTVCE) Note: not change the frequency until you have properly calibrated the output filter. • Set the exciters following the instructions of the exciters that you are used to set the desired operating frequency. Adjust the output power of exciter to the power required to drive your transmitter.
  • Page 14 DTUTT1K2HP1D ELETTRONICA • To adjust the desired working frequency do the following operations: Select Frequency (SET menu), rotate the encoder and then press it to enter in the submenu. Select the Frequency field (working frequency), rotate the encoder and then press it to enter in modality of parameter modification. The frequency channel set emulates the traditional encoder. By placing the cursor in each of the nine digits you can change the value from 0 to 9, so the frequency channel had a precision of 1 Hz.
