A new USB protocol and electrical tester is capable
of performing the suite of tests defined in the USB
Implementers Forum, Inc.'s “Battery Charging,
USB On-The-Go and Embedded Host Automated
Compliance Plan.” The Packet-Master USB-PET from
Saelig is connected to a host PC using a High-Speed USB
connection, and controlled using the GraphicUSB application software, which can generate test
reports and perform analyzer-style captures. USB-PET's front panel features a micro-AB receptacle
and a D-type connector for connection to a unit-under-test. The rear-panel allows the connection of
a meter or oscilloscope for monitoring, for example, VBUS voltage. Single unit price is $5,995.

Unmanaged, Low-Power 12-Port Gigabit Ethernet Switch Module
A rugged 12-port Gigabit Ethernet switch module is an
extremely low-power, high-performance Ethernet switch.
The H2 from North Atlantic Industries supports 16 Kbyte
jumbo frames, 802.1P QoS or DiffServ/ToS priority
queues, 802.1Q VLAN, Port Aggregation, Spanning Tree,
Rapid & Multiple Spanning Tree, NAT, Port Forwarding,
DNS, DHCP and Firewalling. The module can be
mounted on a 3U cPCI or 6U VME rugged board. When
mounted on a 6U VME board, single board computer
and/or additional I/O functions can be added to support
system-level requirements for processing and sensor
interfacing.
The H2 implements standard Ethernet switching
functions via Broadcom technology and features IPv4
and IPv6 traffic class support, automatic learning and
aging tags at 6.6W with 12 x GigE ports active at 85°C.
It also supports a true non-blocking GigE integrated
switch fabric with 4 Mbit packet buffer memory (for L2
functionality) and a high-performance look-up engine
with support for up to 8K unicast MAC addresses.
The H2 module switch enables system integrators
to link Ethernet-based communications, control systems and sensor data across a broad range of
application-ready subsystems. Customers looking forward to the next generation of unmanned
aircraft systems (UAS) and other autonomous robotic systems will take advantage of the high
channel density and extremely low power features our H2 has to offer. In addition, based on NAI’s
COTS, multifunction, high-density I/O and processor platforms (such as 75D3, 64DP3, 64E3),
multiboard systems can be configured combining the H2 multiport GigE switch capability with
application-specific processing and I/O.

Small, Flexible Sensor Measures Temperature and Air Velocity
A flexible, robust candlestick sensor can simultaneously measure both temperature and air velocity for
characterizing thermal conditions in electronic systems. The MS 1000-CS-WC from Advanced Thermal Systems is
a candlestick-shaped sensor that is narrow and low profile to minimize disturbance of heat flow in the test domain.
Its flexible, plastic-sleeved stem eases installation and repositioning during the testing process. MS 1000-CS-WC
candlestick sensors are calibrated for both low (natural convection) and high velocity flows. They are capable of
temperature measurements ranging from -30° to +150°C ±1°C. Velocity measurements range from 0 to 50 m/s
(10,000 ft/min) ±2%. The sensor’s stem is just 0.5 mm in diameter; its base diameter is 9.5 mm. Three different
heights are available: 9, 12 and 20 mm. Prices for MS 1000-CS-WC candlestick sensors start at $180.

PMC Modules Do Cost-Effective
FPGA Processing
A set of new PMC mezzanine modules
features the cost-optimized Xilinx Spartan-6
FPGA. The PMC-SLX reconfigurable FPGA
modules from Acromag can save thousands
of dollars, yet still deliver high-performance
computing for algorithm acceleration and
custom logic processing tasks. Spartan-6
FPGAs have integrated logic, DSP and memory
resources that leverage the flagship Virtex-6
FPGA platform’s architecture and systemlevel
blocks for quicker and smoother system
development. Acromag adds a high-throughput
PCI-X interface, large memory banks, and easy
access to field I/O signals to deliver a readyto-use
FPGA computing module for advanced
signal processing applications. All models
employ the logic-optimized SLX150 version of
the Spartan-6 FPGA, which provides 147,433
logic cells and 180 DSP slices. Dual-ported
SRAM (256k or 1M x 64-bit) facilitates highspeed
DMA transfers to the bus or CPU. The
base price is just $2,895 with extra memory and
extended temperature options available.
