resolution bandwidth of 9 kHz. The demo at
the booth is based on the R&S ESR EMI test
receiver with the R&S ESH3-Z6 line impedance
stabilization network. With its numerous features
for analysis and troubleshooting, the R&S ESR is
ideal as a midrange compliance test receiver.
Rohde & Schwarz is also exhibiting the new fast
time-domain scan (fast TDS) function for the R&S
ESW high-end test receiver. With double the scan
bandwidth, the measurement speed is nearly twice
as fast as a conventional time-domain scan. This
enables faster measurements than ever previously
achieved commercially for time-consuming tests
with a quasi-peak detector. Along with accelerating
preliminary measurements, this method can be
used for certification in the frequency range above
300 MHz. Fast TDS is available at no cost with the
next firmware version for the R&S ESW.
Robust, compact BCI test system
There is also a robust, compact test system
for wired electromagnetic susceptibility
measurements using the bulk current injection
(BCI) test method, as prescribed for testing
electronic modules in vehicles. The BCI system
consists of the compact R&S SMC100A signal
generator, the robust R&S BBA150-AB broadband
amplifier with output power up to 350 W in the
frequency range from 4 kHz to 400 MHz, the
R&S NRP6AN average power sensor specifically
developed for EMC applications, and the widely
used R&S EMC32 measurement software.
Automatic monitoring of display elements
during EMS tests, even with vibrations
For video-based monitoring of status displays,
indicator lamps and screens, Rohde & Schwarz
presents the R&S AdVISE monitoring and analysis
software. The software reliably and automatically
reports any undesired deviations. It can recognize
characters, symbols, display bars and pointer
positions. Version 5, unveiled here, continuously
checks the position of the object under test and
adjusts the evaluation in real time. Vibrations
from motors and shaking from turntables are
no longer obstacles to automated monitoring.
The new technology also simplifies changing
the camera position. If the camera orientation
is modified, the press of a button is all it takes
to adjust the configuration of the monitoring
software to the altered image view. R&S AdVISE
v5 is perfectly matched to the R&S ELEKTRA
EMC test software, allowing users to analyze
events correlated to the associated frequencies,
interference levels and factors such as antenna
positions.
