The new programable FM tuner TPT 3001

The new analog tuner TPT 3001 is the result of
long term development in the Tandberg labs. It is
aimed at the professional market and its outstanding
specification confirms that it is in a class of its
own.

The unbelievable S/N performance has been made
possible by an analog system.

FM Front End

The FM front end is an exciting new design. 8
ganged tuned circuits are used to obtain a startling
performance. DC voltage controlled capacitance
diodes are used as tuning elements and Dual-Gate
MOSFETS are used in the RF stage and the mixer
stage.

Programming Unit

The TPT 3001 employs an ingenious tuning
system. In addition to the main tuning stage, there
is a stage which permits data on 8 pre-tuned FM
stations to be stored in an electronic memory. This
pre-tuning circuit is based on the voltage synthesis
principle combined with a fast analog servo loop to
achieve maximum S/N ratio and frequency stability.

IF selectivity

The filter circuits can be switched to three different
bandwidths. The filters consist of phase-linear
block-filters and pure LC filters to combine high
selectivity with extremely low distortion.

Limiter

The limiter has exceptionally good AM suppression
and interference rejection. Moreover the limiter
guarantees a constant signal output over a very
wide range of signal input level. The high definition
of the signal meter range is also due to the excel-
lence of the limiter circuit.
