EMI pre-compliance analysis option for spectrum analyzers
RIGOL Technologies recently announced a significant addition to its UltraReal
family of real-time spectrum analyzers with the release of a new integrated
EMI Application Mode for EMI pre-compliance measurements. RIGOL's EMI
Measurement Application provides a complete EMI precompliance solution
that enables engineers to measure, compare, analyze, and report on EMI issues
throughout their design process. The EMI Application Mode allows for easy
measurement setup. Features like integrated CISPR bandwidths and detectors,
simple limit line construction, automated multisegment scan, and up to three
simultaneous detectors make it simple to get initial scans and measurements.
Advanced capabilities like real-time detector measurements, automated peak/
limit searches, and simple correction table integration facilitate configuration
of more complex test environments and analysis of results. In addition,
comprehensive setup, storage, and report-generation capabilities make it easy to
document, share, and repeat your tests.

Handheld spectrum analyzer
Bird expands its SignalHawk family of rugged,
handheld spectrum-analyzer products with the
addition of the SH-60S-AOA angle-of-arrival spectrum
analyzer and the SH-60S-TC, offering a balance of
price and performance up to a frequency range of
6 GHz. The new SignalHawk SH-60S-TC and SH60S-AOA provide test coverage for all major wireless
systems in an easy-to-use, fully portable test
instrument. A natural integration of digital maps, GPS
location and signal-strength vectoring, the SignalHawk
AOA provides an easy-to-use interface to not only
pinpoint potential in-band interferers and "rogue"
or "pirate" broadcast locations, but also perform
coverage mapping and "dead spot" identification.

Built for space, DC-DC converters have integrated EMI filters
VPT Inc., a HEICO company, has released its SGRB Series of space-qualified DC-DC converters.
Using advanced gallium-nitride (GaN) technology, the SGRB is capable of very high efficiency-up
to 95%-as well as radiation tolerance. A fixed-frequency, reduced voltage switching topology
results in very low input and output noise, making it suitable for use in telecommunication systems.
Specifically designed for applications facing the harsh radiation environments of space, the SGRB
series has been characterized to total ionizing dose of 100 krad(Si), including enhanced low dose rate
sensitivity, and single-event affects performance to 85 MeV/mg/cm2. The SGRB Series features an
integrated EMI filter, 100 V input and 28 V, 400 W output, and is rated for full-power operation from
−35 to 85°C.
