The GX3722 delivers exceptional flexibility
and utility, with a unique
mix of measurement and
control functionality, in a
single high-performance
3U PXI hybrid slot compatible instrument. Analog
measurement capabilities
include four time-interval channels, each rated at 10 MHz, with channels supporting
both 50 Ω and 75 Ω input impedance. Two digitizer channels,
each with a maximum sampling rate of 10 MS/s, include programmable input impedance and sampling rates with a 24
Vpp input range.
Two channels of multifunction waveform generation deliver Sine, Triangle, Sawtooth, Square, and Arbitrary signals
up to 10 MHz, while four channels of dedicated square wave
generation further complement the source capabilities of this
card. The addition of four 100 kHz differential TTL I/O channels and three open collector output channels (50 V, 2.0 A)
enable control of external devices.
The GX3722 Series is supplied with GxFPGA, a software
package that includes a virtual instrument panel, and a Windows® 32/64-bit DLL driver and documentation.

Economy Vector Signal Generator
The Rohde & Schwarz
SMCV100B generator covers the 5G NR extended FR1
frequency range up to 7.125
GHz, making it suitable
for mobile communications applications. It also
uses the R&S WinIQSIM2
simulation software. This
software supports all common cellular and wireless connectivity standards, including standards for IoT and Wi-Fi (802.11xx)
and many more. In total, more than 30 standards are available,
along with an arbitrary waveform generator to output userdefined signals.
FPGA based real-time coders for broadcast standards used
worldwide are available. The R&S SMCV100B supports analog and digital radio standards as well as second and third
generation digital terrestrial and satellite-based television
standards. This is the first economy platform that supports
ATSC 3.0 in addition to the DVB-T2 and DVB-S2X standards.
The R&S SMCV100B uses an advanced direct RF concept
to generate output signals for frequencies up to 2.5 GHz. This
December 2020	

allows I/Q modulation and RF signal generation to be performed in the digital domain, virtually eliminating the I/Q
imbalance errors and LO leakage commonly seen with conventional analog I/Q modulators. Thanks to the new concept,
the SSB phase noise performance of the signal generator is particularly good. An analog mixing concept is used to generate
frequencies above 2.5 GHz.
The high-performance, Linux based platform is completely
extensible using software options. All options are present in
the device firmware and can be activated with option keys
as needed. This includes frequency extension up to 6 GHz or
7.125 GHz, increasing the RF modulation bandwidth to 250
MHz, raising the RF output power to 23 dBm and waveform
streaming with up to 60 MHz (75 Msymbol/s) RF bandwidth.

4-Channel Transient Data Acquisition
System
CAS DataLoggers, in partnership with Delphin
Technology, introduces a
new model of the
Expert Transient data
acquisition system, the 4
channel ET-4. Designed for
data acquisition and fault diagnostics, this system is especially
suited for smaller applications that only require a few analog
input channels. A key feature of the Expert Transient family is
the ability to synchronously acquire multiple analog channels
at sample rates up to 50 kHz. The ET-4 can operate as a standalone device recording to internal memory to capture both
transient and periodical data.
In the event of a fault, this enables precise identification of
the sequence of events in a malfunction. Measurement data
can be recorded either continuously or according to trigger
conditions and events including the ability to define triggers
to record pre- and post-event data. The ET-4 is equipped with
powerful FPGA technology that provides extensive on-board
intelligence for calculations, logic, and data analysis.
In addition to the 4 analog input channels, the ET-4 has 4
digital inputs to capture pulses, discrete inputs, or digital triggers. An extension bus allows the system to be extended to
over 100 analog or digital inputs with high-speed synchronization protocols.
Features:
◗◗ 24 Bit A/D for high resolution measurements
◗◗ DataLoggerInc.com New 4-Channel ET-4 Expert Transient from Delphin 2
◗◗ 4 Analog outputs
◗◗ 8 Digital outputs
◗◗ Programmable anti-alias filtering
