SETUP
Summary
The setup menus are used to route the outputs from the signal sources to either their individual RF
OUTPUT sockets or, via the combiner, to the CONNECTION TO RADIO socket and additionally
allow the sources to be coupled together by a mathematical formula in both frequency and level.
The routing is set using the combiner setup facility and the coupling parameters are enabled and set
using the coupling setup facility.
The applications facility allows the user to select one of a number of common test configurations,
such as intermodulation testing for two signal sources. When an application is selected the most
appropriate signal routing is automatically chosen and the required coupling controls enabled.
Control parameters are then redefined in terms of the measurement being performed to minimize
the number of parameter entries required. For example, for intermodulation testing with equal
amplitude sources, only one RF level control is provided and this automatically sets the level of
both sources. Control parameters are described in terms which are relevant to the measurement
being performed.
Setup menu selection
Pressing the [SETUP] key gains access to the
Setup Menu
similar to that shown in Fig. 4-1 below.
Fig. 4-1 Setup menu
The
[Appl’n Menu]
key accesses the
Applications Selection Menu
which enables you to select one
of the three predefined applications. The
[Combiner Setup]
key accesses the
Combiner Setup
Menu
which enables you to connect the signal sources in any combination to the combiner. The
combined signal is then available at the CONNECTION TO RADIO socket.
[Coupling Setup]
accesses the Frequency and Level Coupling menu which enables you to couple the B source to the
A source. This source can then track the A source by means of a level offset and a frequency and
harmonic offset.
