Type Acceptance Information for TS4000 Radio Modem with 3422 Transceiver
Proposed FCC ID JWFTS4000C
PURPOSE
The purpose of this document is to provide information in support of type acceptance testing and
report generation in pursuit of a Grant of Equipment Authorization under FCC Parts 15 and 90 and
Industry Canada RSS-119, RSS-210 and ICES-003 for Teledesign’s TS4000 Radio Modem.
INTRODUCTION
The TS4000 is a high-speed radio modem that consists of a modem board, radio transceiver
board and metal enclosure. The radio transceiver board connects to the modem board with a
flexible printed circuit.
Radio Transceiver Board
The radio transceiver board for this application is an E.F. Johnson DL3422. This device is being
used without any modifications. The DL3422 has received FCC type acceptance with an FCC ID
of ATH2423422-007. All circuit descriptions and details for the radio transceiver can be found in
the type acceptance document for the DL3422. A copy of this has been included with this
application. The radio transceiver is available in a frequency range from 132-174 MHz and
includes a temperature stable reference oscillator with a frequency stability of ± 2.5 PPM.
Modem Board
The modem board provides the serial data interfaces that the user’s equipment interfaces to. The
modem board also controls the operation of the radio transceiver. This control includes
controlling the radio power and frequency and also controlling the modulation, data rate and
frequency deviation of the transmit signal. Note that it is this transmit signal that defines the
emission bandwidth and spectral efficiency.
Radio Flex Circuit
A flex circuit is used to interconnect the radio transceiver board to the modem board. This flex
circuit is also used to interconnect the serial port 2 connector to the modem board. The J11
interconnecting diagram included with the modem board schematic provides the specific
connections provided by the flex circuit for connecting the radio transceiver to the modem board.
Configuration Software
IBM compatible configuration software is used to control all aspects of configuration, tune up and
test of the TS4000 radio modem.

and 90.79(d)(6) only).
Emission Designator Calculations:
Modulation Types:
The TS4000 is designed to use three modulation types: 4 level FSK, GMSK with a BT=0.5 and
GMSK with a BT=0.3. The 4 level FSK modulation is provided to allow a high spectral efficiency
for a given channel bandwidth. The GMSK modulations are provided in order to be compatible
with other products and data communications standards.
Channel Bandwidths:
Our goal is to certify the TS4000 at four different channel bandwidths: 20K0, 16K0, 11K2 and
6K00 (the use of the 6K00 bandwidth is limited to the subparts shown above). This is to allow the
TS4000 to be setup for the most efficient operation for a given channel bandwidth that a user is
licensed for.
