The miniature LVCM-019022-02 linear voice coil motor,
also called a linear DC motor,
has a 0.5-in. (12.7-mm) stroke
and a high force-to-size ratio.
It produces 8.1 oz. (2.3 N) of
continuous force and 25.7 oz. (7.1
N) of peak force in a compact
0.750-in. (19.1-mm) diameter x
0.875-in. (22.2-mm) housing. This
miniature high-speed / highacceleration servo motor may
be used in a closed-loop servo
loop. This zero-cogging, clean,
quiet, efficient, low-inertia, highacceleration, miniature voice-coil
motor is suitable for pick-andplace, testing, laser steering,
laser speckle reduction, mirror
positioning, scanning, oscillation,
switching, clamping, and haptic
feedback in handheld medical,
dental, or industrial applications.

RIGOL's RSA3000E spectrum
analyzers bring the power of
UltraReal real-time analysis
to customers who previously
had no access to this advanced
capability. The RSA3000E
combines a high-performance
swept spectrum analyzer with
the analysis capability of a realtime analyzer. The RSA3000E is
available in 1.5-GHz and 3-GHz
models with available tracking
generators and a starting price
of $1,799. The instrument comes
standard with 10 MHz of real-time
analysis bandwidth with seamless
capture and a 9.3-ms 100% POI.
The RSA3000E provides the same
seven visualization modes and
triggering capability as RIGOL's
other UltraReal products, at a
lower entry price.

The Model CBT-LGA-5019 LGA
socket meets high-performance
requirements for 1-mm-pitch
optical engines. The contactor is
a stamped spring pin with 19-g
actuation force per pin and cycle
life of 125,000 insertions. The
self-inductance of the contactor
is 0.93 nH, insertion loss is < 1
dB at 23 GHz, and capacitance
is 0.097 pF. Current capacity of
each contactor is 4 A. Socket
temperature range is -55°C to
+180°C. The socket features
an IC guide for precise LGA
edge alignment. The specific
configuration of the package to
be tested in the CBT-LGA-5019 is
LGA, 33-mm x 33-mm body size,
32 x 32 array, and 1-mm pitch.

Vitrek's PA920 Series ultrahighaccuracy power analyzer
(accuracy of 0.024% of reading)
integrates a wideband waveform
digitizer with advanced
computational capability, a large
high-resolution display, and a fullcolor touchscreen user interface.
The multichannel PA920 offers
0.024% power-measurement
accuracy for all channels (one to
four channel cards available per
unit), innovative VPA architecture,
100 full precision readings per
second, and measurement
bandwidths sufficient to handle
5-MHz signals. The unit's intuitive
touchscreen operation-with
built-in data history, scope mode,
and waveform zoom-allows
detailed power measurement.
