III --- ADJUSTMENTS AND TUNING
The DTU25C is a new series of digital transcoders offered by Pineapple Technology, Inc. The
latest in LDMOS device and circuit technology are employed to ensure reliable and serviceabl
e
operation for many years.
There are very few adjustments necessary to maintain full service condition. Typically the gai
n
adjustment shown in the initial Transcoder Turn-On Procedure (Section IV) of this manual should
require minimal attention. The front meter panel has been set up so that 100% indication in
Forward Power is equivalent to 25W average output power.
The input frequency (channel) can be adjusted, within the auspices of the broadcasting
re-transmission rights, to the appropriate required channel (See Larcan Manual). The transmitter
output must remain on the channel licensed by the FCC and in accordance with the supplied
digital mask filter.
