In the “Settings” window ten different instrument set-ups can<br />
be saved and recalled. This responds directly to the front panel<br />
function of the instrument.<br />
There are three different modes to display data after acquisition<br />
by the Spectrum Analyzer: “Sample” (actual curve A),<br />
“Reference B” or “A-B”. When the function “Calculation” is<br />
activated one of the following curves may be indicated: “Max.<br />
Hold” or “Average”. The “Max. Hold” and “Average” curves<br />
are calculated in real-time. After a mouse click on button “Reset<br />
Calculation” the sampling will be started anew. The window in<br />
the right area (“Read/View”) enables the user to select the data<br />
type to be transferred from the instrument to the PC and the<br />
curve(s) to be displayed on the screen. The attached colors are<br />
explained at the right edge of the window, the time stamp for<br />
the last acquisition is indicated at the upper edge. The calculation<br />
of the curve data is switched off with “Calculation off”. Neither<br />
the “Max. Hold” nor the “Average” curve will be actualized in<br />
this state since data acquisition inside the instrument is switched<br />
off. The displayed curves may be erased by a mouse click on<br />
button “Erase”. After modifying the value for center frequency<br />
the curves will be erased automatically and calculated anew during<br />
the next data transfer from the instrument to the PC.<br />
EMC Mode Functions, Software tasks<br />
The EMC Mode enables the user to integrate the Spectrum<br />
Analyzer as one device into a pre-compliance EMC test system.<br />
Normally a test system like this is an assembly of several devices.<br />
The software package supports the definition of dedicated test<br />
procedures as well as the configuration of the attached devices.<br />
A typical test system is a composition of:<br />
LISN, BNC cable and receiver (Spectrum Analyzer) or<br />
Antenna, amplifier, BNC cable and receiver.<br />
Supported by integrated procedures the user is able to define an<br />
entire EMC test system including all attached components. The<br />
spectral response of each single component can be used for<br />
correction calculations. The frequency response data of each single<br />
component is stored in a dedicated database and used for correction<br />
calculations according to a test system set-up, which - in a dedicated<br />
window - can be defined in a pipeline arrangement of components<br />
and then stored as an entire EMC test system procedure.<br />
