A&D, communications, automotive, etc., "
he said. " For instance, we are adding new
options to the R&S FSH handheld spectrum analyzer for EMF measurements
and for capturing I/Q data. Both the R&S
FSH and R&S ZPH can be equipped with
waveguide calibration and measurement
and EIRP measurement, to just mention
a few new features. "
Battery life is another key feature. " We
heard regularly from customers that they
wanted devices to last an entire day in the
field, " Markley said. " With instruments
like our FPH Spectrum Rider, users can
get up to eight hours of battery life on a
single charge, and with our ZPH analyzer
they can even get up to nine hours. " In addition, the batteries are field-swappable.
Anritsu offers portable instruments
such as the IQ Fiber Master MT2780A
multiport CPRI-based RF and PIM
analyzer, which a spokesperson called
the first instrument to perform true
PIM analysis over fiber and present RF
spectrum results derived from IQ data.
The MT2780A provides field engineers,
field technicians, and third-party
contractors with
one instrument
to conduct RF
interference measurements and PIM
troubleshooting on
LTE-based systems
using CPRI front-haul
infrastructure.
Recently Anritsu and
COMINT Consulting confirmed the compatibility of the COMINT
Krypto1000 wideband signal analysis
and decoding suite with IQ data captured with the Anritsu Field Master Pro
MS2090A handheld real-time spectrum
analyzer (RTSA). The MS2090A performs
capture and streaming of up to 110 MHz
of IQ bandwidth across 54 GHz, providing
a range of RF IQ data for post processing
to deliver a deep view of SIGINT and/or
COMINT activity. The new capability
builds off the IQ capture and IQ streaming options launched for the MS2090A
earlier in the year, the Anritsu spokesperson explained, adding that options made
the RTSA the first handheld analyzer to
capture 110 MHz of IQ data.

Pico Technology offers the 5000D Series
FlexRes oscilloscopes and MSOs, which
Trevor Smith, business development
manager, described as laboratory-grade
instruments that are compact enough
to be deployed in the field or at home.
" They feature up to 16 bits of vertical
resolution with up to 200-MHz bandwidth and 1-GS/s sampling speed, " he
said. " FlexRes hardware employs multiple high-resolution ADCs at the input
channels in different time-interleaved and
parallel combinations to optimize either
the sampling rate to 1 GS/s at 8 bits, the
resolution to 16 bits at 62.5 MS/s, or other
combinations in between. " He added that
the PicoScope 5000D MSO models add
16 digital channels, providing the ability to time-correlate analog and digital
channels. As for battery life, Smith said
a PicoScope can be powered from the
host PC. " A PicoScope 5000D with two
channels running draws less than 1 A,

so it's the PC power pack that needs to
be selected accordingly, " he explained.
Subbaiah Pemmaiah, applications engineer at Copper Mountain Technologies,
said the company has recently introduced
vector network analyzers (VNAs) in its
Compact family, including the S5045,
M5045, SC5065, S5180, and M5180.
" All our VNAs are USB-based
and without a builti n c o m p u t e r, "
Pemmaiah said.
" This innovative
approach separates the measurement module (VNA) from the

processing module (PC), which allows
the user to take advantage of the newer
and faster processors available with modern computers, and yet not compromise
on the measurement accuracy. With
the elimination of the built-in PC, these
analyzers are much smaller and lighter
compared to the traditional analyzers. "
Pemmaiah said Copper Mountain's
analyzers do not have a built-in battery
pack. " Since these analyzers require very
low power, one can easily identify and
purchase an off-the-shelf battery pack
available on the market and run them
continuously for a day, " he said.
Newark offers a variety of instruments,
and the PicoScope 6000E Series, a fixedresolution and FlexRes oscilloscope, was
recently added to the distributor's range,
according to Jay Wimsatt, director of
product operations, Test & Measurement,
Newark. " The 6000E Series scopes are
available in 4- or 8-channel configurations, which provide 8 to 12 bits of vertical resolution, up to 500-MHz bandwidth,
and 5-GS/s sampling rate, " he said. " These
units can display single-shot pulses with
200-ps time resolution. "
The PicoScope 6000E Series features
deep capture memory-up to 4 GS in
total, Wimsatt added. " This ultradeep
memory allows the oscilloscope to capture 200-ms waveforms at its maximum
sampling rate of 5 GS/s, " he said. " USB
3.0 interface and hardware acceleration
ensure the display is smooth and responsive even with long captures. Eight analog channels have sufficient timing and
amplitude resolution to reveal signalintegrity issues such as glitches, runts,
dropouts, noise, distortion, and ringing. "
