Operating Instructions for the Transmitter (Stand-Alone Configuration)
The Bosch Telecom Node Transmitter, under operational conditions, is under control of the
SpectraPoint
determines the operating frequencies and power levels and monitors the performance of the
system.
For stand-alone testing such as functional checkout or compliance testing, the transmitter may be
operated at maximum rated output power with automatic power control disabled and commanded
to various operating frequencies within the allocated band of operation and with actual and
simulated IF input signals.
The User Manuals delivered with the SpectraPoint
system but does not include stand-alone operation of the individual components of the system.
Therefore, this document describes the equipment setup and operation employed for stand-alone
operation of the Transmitter, as applicable to compliance testing.

Tune-Up Instructions for Operation of a Single Transmitter
1.0 Scope
This document provides the tune-up instructions for operation of a single SpectraPoint
Node Transmitter, when operated for test purposes (i.e., without the control of the
SpectraPoint System for which it is intended to operate).
2.0 Introduction
Transmitters, when operating under control of the SpectraPoint System, are “automatically”
commanded to the correct operating frequency (i.e., the correct intermediate frequency
signal input, both tuned frequency and amplitude, and the correct local oscillator frequency)
and provided with the correct reference frequency, to be caused to transmit at the
appropriate RF output level for range and path conditions. However, for test purposes,
control of these signals must be provided by test hardware and software which is defined in
this document.
3.0 Interconnection of Support Equipment
The interconnection of the SpectraPoint Node Transmitter and support equipment is shown
in Figure 8-1 and support hardware and software is contained in Table 8-1.
The Node Transmitter may be operated to produce a CW output (pilot tone for SpectraPoint
System), a single QPSK phase modulated output (simulating single-channel QPSK used in
the SpectraPoint System at service-provider-selectable bandwidths) or a multiple-channel
QPSK phase modulated output (simulating multi-channel modem-generated signals).

4.0 Description of the test and support equipment
4.1 Bosch Modem Test set
The Bosch modem test set consists of the central shelf, expansion shelf and a -48Vdc
power supply. The expansion shelf consists of slots for 14 modem circuit cards (plus two
spares), a combiner circuit card and a power supply module. The central shelf consists of
RASCO module, six modem circuit cards, one broadcast modem circuit card, one combiner
circuit card, a power supply module and an IF translator module. In a typical operation (and
for test) only 20 modems are used. A diagram of this test set is shown in Figure 8.1. On the
RASCO, there is a DB-25 connector labeled as Serial Port 2.
An RS-232 cable should be connected between the RASCO serial port and the COM1 port
(DB-9 connector) on a PC running Windows95. Only three pins on these ports are required
for communication as shown in the following table:
DB-9, COM1 DB-25, RASCO Signal
Pin 2 Pin 3 Tx
Pin 3 Pin 2 Rx
Pin 5 Pin 7 Gnd
This cable is used for communication with the modems and the translator through the
RASCO u sing the Bosch Sec tor Controller program ( SECO).
4.2 AWG-2021 & SMHU-58 Test Set
This test set is used to generate an arbitrary waveform at the desired IF frequency to
produce a simulated QPSK signal at any specified code rate or channel bandwidth. The
channel bandwidth may be 30, 40 or 50 MHz depending on the type of communication. The
Tektronix AWG-2021 generates the filtered I and Q signals which are applied to the Rohde
& Schwarz SMHU-58. The SMHU-58 uses the I and Q signals to produce a phasemodulated L-Band IF signal for input to the node transmitter. Both AWG-2021 and SMHU58 are connected to a PC by HP-IB cable to the PC. Tektronix software (IQSIM) is used to
generate the I and Q signals and download these signals to the SMHU-58.
4.3 Junction Box
The junction box provides the mechanical interface and the electrical connectivity to provide
-48Vdc and control signals to the node transmitter utilizing actual system cabling.

4.4 Reference Tone Generator
A CW generator (HP 83640L or equivalent) is used to generate a continuous tone at 960
MHz to provide a reference frequency to the node transmitter simulating the reference
signal from the Frequency Reference System in the Control and Monitor rack. The normal
power level of the reference input to the transmitter is –5 dBm (range is -7 to 0 dBm).
4.5 Node Transmitter
The transmitter consists of a local oscillator module, HPA/Upconverter module, a
waveguide filter, an antenna, and a polarizer mounted in a chassis. For some tests, the
antenna and the polarizer may be removed and a waveguide adapter plate (part number
3214985) connected directly to the waveguide filter. The transmitter, the equipment under
test (EUT), upconverts an L-Band IF input signal to produce a Ka-Band RF output signal
and provides power amplification. It receives the IF signal from either the Modem Test Set
or from the SMHU-58 and the LO reference from the reference tone generator via coaxial
cables. The power and control signals are provided through the junction box through a
multi-conductor cable.
4.6 Waveguide Directional Coupler
A waveguide directional coupler (Millimeter Products 559A-20/599, or equivalent) is
attached to the waveguide adapter plate at the output of the transmitter to facilitate the
measurement of the output power and spectral analysis. A power meter is connected to the
20dB-coupled port and a spectrum analyzer is connected to the through-port of the
waveguide.
4.7 Power meter
An RF power meter (Anritsu ML2438A, or equivalent) is used to measure the output power
of the transmitter. All the test measurements are taken at the maximum output power from
the transmitter, which is +30dBm. The maximum power which the power meter can handle
is +20dBm, therefore, it is connected to the coupled port of the waveguide which is 20dB
down from the input port.
4.8 Spectrum Analyzer
A spectrum Analyzer (HP 8564E) is used to monitor the output of the transmitter and
measure power spectral density, channel power and occupied bandwidth. A DC block is
used on the input to the spectrum analyzer for protection. Sufficient series attenuation
should be used to protect the spectrum analyzer.
