Setting Frequency
When a TETRA System is selected, the frequency of the 3900 RF Signal Generator and Receiver can
be defined by the user when No Plan is selected as the Channel Plan. Refer to Chapter 4, section
titled Channel Plans Configuration Tile for information on configuring Channel Plans.
Data Display
Data Display Mode allows data bursts transmitted by base stations and mobiles to be examined. The
data is displayed as demodulated burst data after de-scrambling and channel decoding have been
performed.
Use of Data Display Mode is described in the section titled Data Display Mode in Chapter 2, Common
TETRA Operation.
Spectrum Analyzer
The Spectrum Analyzer allows the RF spectral range of the Test Set to be examined.
Refer to Chapter 6 of the 3900 Series Operation Manual for a detailed description of the use of this
instrument.
Channel Analyzer
The Channel Analyzer examines the spectral emission of the RF signal from a TETRA Mobile or Base
Station over a 5 MHz bandwidth, centered on the set Channel Frequency. The MMI is provided by
the Channel Analyzer.
The signal for the Analyzer is obtained from the receiver chain of the Test Set, in parallel with
signals to the TETRA signal processor.
Refer to Chapter 6 of the 3900 Series Operation Manual for a detailed description of the use of this
instrument.

RF Connections
Prior to testing, connect the 3900 and the equipment under test with a suitable RF cable.
Refer to the 3900 Series Operation Manual, Test Setup in Chapter 1, to identify the appropriate
RF connectors (T/R Connector, GEN (Generator) Connector, ANT (Antenna) Connector to be
used on the Test Set.
Audible and Visual Overload Warning
If the RF Signal applied to the ANT (Antenna) Connector exceeds the safe maximum level, an
audible and visual warning are triggered. The overload warning is also triggered if excessive
reverse power is applied to the GEN (Generator) Connector.
If the warning triggers, reduce the input power immediately.
Do not power down the Test Set; this does not remove the overload power from the connection.
Do not disconnect the RF cable from the Test Set as this may cause burns to hands.
Manual Testing
Manual testing enables specific parts of the operation of the mobile or base station under test
to be tested. The required signaling is generated by the Test Set.
Automatic Testing
The 3900 AutoTest System provides the ability to verify the performance of mobile radio
equipment using test scripts to automate a sequence of tests. The AutoTest System is
selected from the CONFIG Menu.
When a Script is loaded into the system and instructed to ‘run’, a command in the script causes
the Test Set to open the appropriate Test System, configure the Test Parameters for specific
tests and record the Test Results. The progress of the script is shown on the display.
Refer to Chapter 3, TETRA MS AutoTest Commands for information on AutoTest Commands in
relation to TETRA MS. Refer to the 3900 Series Operation Manual for general information
concerning the AutoTest System.
Remote Operation
TETRA Systems can be operated using the 3900 GPIB/IEEE-488 remote control feature. Refer
to the 3900 TETRA Programming Manual for information about using TETRA Remote Control
Commands.
