9.3 Test Automation
Access : "Overview" > "Test Automation"
The "Test Automation" dialog box is a tool to configure and perform measurements in
the Receiver application. The dialog box contains a tab for each typical stage in an
EMC measurement (scan, peak search and final measurement). The dialog box also
summarizes the measurement results for these stages in separate tabs.

9.3.1.1 Selecting the Measurement Bandwidth
The measurement bandwidth corresponds to the bandwidth of the resolution filter. The
RF signal is evaluated and displayed according to the bandpass characteristics of the
resolution filter.
The receiver application supports the following types of resolution filter.
●
Filters with a 3 dB bandwidth
The R&S ESW provides bandwidths with a stepsize of 1-2-3-5-10-.... For details,
refer to the data sheet.
●
Filters with a 6 dB bandwidth
The 6 dB bandwidths are designed and required for receiver tests and measure-
ments. The R&S ESW provides bandwidths that comply to commercial and military
standards. For details, refer to the data sheet.
Note that the available bandwidth is limited by the current receiver frequency. The
measurement bandwidth must be less than or equal to half of the current receiver fre-
quency:
