Vector Network Analyzer
The market and range of
applications for the vector network analyzer have
grown in recent years and
continue to do so. Growth
is not simply driven by
the proliferation of microwave, gigabit, and wireless
signals in our lives, but also
in penetrating and short-range radar imaging and proximity
detection in secure spaces, and in dielectric materials, tissues
and composites. The vector network analyzer sits behind our
data flow, communications, food, healthcare, defense, civil infrastructure, robotics, and automation.
The newly announced PicoVNA 108, is in the same lowcost, small-footprint and portable format as before. The
PicoVNA 108 can see out further to 8.5 GHz, and it can see
down deeper to -124 dB.
Many users are aware that calibration standards and interconnects can both dominate measurement errors in network
analysis, so Pico supports both PicoVNA models with lowcost but equally useful SMA and PC3.5 calibration standards
and test leads, all with precision-machined stainless steel
connectors. PicoVNA software supports 8- or 12-term calibration, including the " unknown thru " method. Unwanted
measurement contributions from feedlines or test jigs can be
eliminated using manual or auto-sensed reference plane shift,
normalization, or de-embedded Touchstone, taken from either
measurement or EM simulation. Fast Fourier time-domain
transformation and impedance transformation are both included as standard. TDT / TDR plots have a system rise time
down to 58 ps and these support resistance and distance to
fault readout out to over 100 meters.

Compact, Low-Cost Optical Power
Meters
PI introduces two new optical power meters for automated
photonics alignment applications. The F-712.IRP1 and its
70	

two-channel counterpart,
the F-712.IRP2, convert
optical signals in the 600
nm to 1700 nm range with
optical power from 230 picowatts to 1.3 milliwatts
into an analog output voltage of 0.1 V to 1.6 V. To be
useful for fast optical alignment systems, the output signal conversion is logarithmic and
optical power changes can be detected and converted with a
bandwidth of 6 kHz.
The logarithmic output scaling is especially important for
fast scans and gradient search algorithms because the signal
strength can fluctuate by several orders of magnitude within a
few milliseconds, considering the minute dimensions of modern fiber optical components, such as waveguides and arrays.
The broad optical range from 600 nm to 1700 nm allows
for usability in both the visible and infrared range without
switching.
A clever design of the optical input connector / socket interface eliminates the influence of the position of the optical
fiber in the connector on the optical signal.

Amplifier Spans 10 kHz - 400 MHz Range
With 1000 Watts of Power
AR's new amplifier, Model
1000A400, provides CW
power up to 1000 watts,
covering 10 kHz to 400
MHz. In conjunction with
AR's accessories and antennas, the 1000A400 is
optimal for reaching today's higher radiated
and conducted susceptibility test levels, such as
the increased conducted
immunity test levels of
composite aircraft in the
frequency range of 10 kHz
to 400 MHz, along with
many other applications.
Some key features of AR's Model 1000A400 are:
◗◗ Rated Output Power: 1200 watts typical, 1000 watts
minimum
◗◗ Power Output @ 1dB Compression: 1000 watts typical,
800 watts minimum
◗◗ 10 kHz - 400 MHz instantaneous frequency response
◗◗ Class A
◗◗ Portable
