    Introspect’s SV3C CPRX 4-Lane C-PHY Analyzer wins Best in Design and Test Award

Introspect’s SV3C CPRX 4-Lane C-PHY Analyzer wins Best in Design and Test Award

The SV3C CPRX 4-Lane C-PHY Analyzer is an ultra-compact solution for the design, verification, and electrical validation of high-speed components based on the emerging MIPI Alliance C-PHY specification. C-PHY is a new physical layer standard that allows for significant bandwidth improvements on constrained transmission channels, such as those found inside mobile terminals. Based on innovative signaling and encoding technologies, C-PHY devices require an entirely new breed of test and measurement equipment, and Introspect’s SV3C CPRX 4-Lane C-PHY Analyzer represents the only tool in the industry capable of both analog signal capture and complete BER detection and protocol analysis. Unique to C-PHY technology is that signals emanating from transmitters are single-ended and multi-level in nature; yet receivers operate on differential signal pairs encoded in multiple phases. This means that symbol transmissions are not deterministic and are thus not easily visualized on conventional tools such as oscilloscopes or basic logic analyzers. The SV3C CPRX offers the only tool in the industry to automatically decode the symbol transmissions and display received packets in human-readable format. It has proven indispensible for first-time bring-up of early C-PHY test chips at leading adopters of the C-PHY standard.

RF/Microwave Power Sensor Works Unattended

Covering a frequency range of 1 MHz to 18 GHz, the LB5918A power sensor from LadyBug Technologies performs general-purpose average power, true RMS, and scalar measurements with a dynamic range of –60 dBm to +20 dBm. Once measurements are set up, the sensor needs only a power supply to enable unattended operation for use in such applications as test and measurement, radar, satellite communications, and research and development.

The LB5918A logs up to 1000 measurements/s and stores over 100 million measurements in nonvolatile memory. Its real-time clock with internal backup provides time-stamped data for measurements stored in memory. USB HID and USBTMC interfaces offer platform-independent connectivity to most computers, while optional SPI/I2C interfaces can be used for embedded applications. The power sensor is programmable using industry-standard IEEE 488.2 SCPI commands via all three interfaces. LadyBug’s NoZero NoCal feature eliminates the need for zeroing and calibration prior to performing measurements.

Housed in a sturdy aluminum housing, the LB5918A is 1.6 in. in diameter and 3.0 in. long. It is supplied with a power-meter application that provides tabular logging, strip charting, analog gauge display, and math measurement windows that allow calculation between multiple sensors. The software also lets users set up unattended operation, the real-time clock, and other sensor features.

    Pickering Interfaces’ High-Density PXI Multiplexer Selected for Aircraft Lightning Protection Testing

Pickering Interfaces’ High-Density PXI Multiplexer Selected for Aircraft Lightning Protection Testing

Pickering Interfaces announced that a major UK manufacturer of aircraft engine control units recently awarded them a contract for a large quantity of High-Density PXI Multiplexers (model #40-651) as the switching solution for use in its new automated production test systems. These systems will be used to test FADEC (Full Authority Digital Engine Controller) lightning-strike protection components on Airbus’ A330 and A350 as well as Boeing’s Dreamliner aircraft.
The customer needed to test the transient-voltage-suppression diodes, or transorbs, used to protect the FADEC’s sensitive electronics from very fast voltage spikes induced on connected wires following a lightning strike on the aircraft. Due to the quantity of transorbs that needed to be tested (one on every I/O connection of the FADEC), a large number of high-power multiplexers were required to connect the UUT to the test instrumentation.
The customer required a compact, modular test architecture for scalability and ease of maintenance and selected PXI as their preferred platform. With no high-density PXI multiplexers of the required performance commercially available, the customer approached Pickering (a preferred PXI switch supplier) to discuss their options. Pickering’s engineers subsequently designed, built and tested a new PXI multiplexer to their specification. Following a successful trial of the initial prototype, Pickering worked closely with the customer to simplify the test system wiring by adding a second connector to the multiplexer for the MUX common connections. This led to a preliminary order for 84 multiplexer modules, with additional future requirements planned.
The 40-651 High-Density PXI Multiplexer is a COTS (Commercial-Off-The-Shelf) product and is available worldwide. For specifications and pricing please visit the Pickering web site at pickeringtest.com.

New Range of Mixed-Signal PicoScopes

The new PicoScope 3000D Series Mixed-Signal Oscilloscopes (MSOs) are ideal for engineers working on a diverse range of embedded systems. These compact USB-connected devices form a complete portable test system, with two or four analog channels and sixteen digital channels as well as a built-in arbitrary waveform generator.
“We have completely redesigned the PicoScope 3000 Series MSOs,” explained Managing Director Alan Tong. “The key specifications—sampling rate, buffer size and display update rate—have all been improved, while we’ve retained the benefit of USB-powering that makes PicoScopes so much more convenient and portable than their traditional bench-top equivalents.”
The PicoScope 3000D Series MSOs are available with analog bandwidths from 60 MHz to 200 MHz. Maximum digital input frequency is 100 MHz, equivalent to a data rate of 200 Mb/s (5 ns pulse width) on each channel. All models come with a USB 3.0 interface and are fully compatible with USB 2.0, giving high performance and fast update rates with both port types. Like all PicoScopes, they display waveforms in a resizable window on your PC’s screen, giving you an uncluttered space for multiple high-resolution analog and digital traces. It’s easy to save, share and analyze waveforms, with all of your PC’s networking, storage and processing facilities instantly available. The deep memory buffers of 128 to 512 mega samples, much larger than other scopes costing several times more, allow long captures even at fast real-time sampling rates of up to 1 giga-sample per second. Hardware-accelerated data processing maintains smooth and rapid display updates even with very large capture sizes.
The PicoScope 3000D Series offers a comprehensive suite of advanced features as standard, including math channels, automatic measurements with statistics, spectrum analysis and color persistence display mode. Also built in are advanced digital […]

New PCI Precision Resistors Cards for Budget Conscious Test Systems

Pickering Introduced Two New Additions to PCI Precision Programmable Resistor Card Range
RTD Simulator and Strain Gauge Simulator Cards
PCI is used extensively in budget conscious test systems using Industrial PC chassis especially for Hardware-in-the-Loop (HIL) simulation. There remains a strong demand for the PCI format and we are expanding our range of PCI switching products to address those market opportunities. We are pleased to announce the following additions to our PCI precision programmable resistor card family:
PCI RTD Simulator Cards (50-262)
These RTD simulator cards contain six resistance channels each with exceptional resistance stability and fine setting resolution characteristics. Intended for the emulation of PT100 and PT1000 resistive temperature sensors, the 50-262 PCI RTD simulator range is offered with two resistance ranges; 90 to 250 Ohm and 900 to 2500 Ohm with the PT100 version providing 8 mOhm setting resolution. Each programmable resistor can be programmed with resistance calls which set the resistance of the module to an accuracy of 0.1%
PCI Strain Gauge Simulator Cards (50-265)
These strain gauge simulator cards are offered with six bridge channels, each channel simulates a strain gauge bridge. Four different models are offered in the 50-265 PCI strain gauge range, they include 350 Ohm, 1 kOhm, 2 kOhm and 3 kOhm bridges. Each model allows very fine adjustment of the bridge resistance to allow emulation of high or low stresses using simple resistance calls. Each channel has a stored value corresponding to the bridge being in balance and the bridges can be driven from either an internal voltage source or an externally supplied voltage from a bridge measuring system.
Both of these PCI precision programmable resistor solutions are part of our increasing family of switching and simulation products available in the mature PCI format. We are committed to supporting these PCIswitching solutions in the same way we […]

    Pickering Interfaces Expands Range of PXI High Power Solid-State Switches

Pickering Interfaces Expands Range of PXI High Power Solid-State Switches

Pickering Interfaces, a leading provider of modular signal switching and instrumentation for use in electronic test and simulation, is pleased to introduce two new PXI high power solid-state switch modules to its range of PXI switching solutions

 

PXI 25A Solid-State SPST Switch (40-184) – offer 3 or 6-off SPST solid-state switches capable of handling 25A signals at up to 100V.

 

PXI 1.5A Solid-State SPST Switch (40-185) – offer 3 or 6-off SPST solid-state switches capable of handling 1.5A signals at up to 400V.

 

Both of these new PXI switching solutions use solid-state switch designs based on isolated MOSFET technology to provide solutions capable of switching very high power AC or DC signals without any lifetime degradation while used within their ratings. The solid-state SPST switches feature a fast operating time of less than 250µs and bounce-free state transitions that can handle high inrush currents on switching without any impact on lifetime.

 

These new switching modules are particularly well suited to use in PXI applications where higher voltages and powers are required. Applications include testing products used in transportation systems where mechanical relays are generally unsuitable because of limited switching capacity at the voltages and currents required.

 

For each model the 3-off SPST versions occupy one 3U PXI slot while the 6-off SPST versions require two 3U PXI slots. Each model uses robust high power D-type connectors that are fully supported by Pickering Interfaces’ range of connection accessories. The modules can also be supported in Pickering Interfaces LXI Modular chassis’ for users preferring Ethernet control of switching systems.

 

Pickering Interfaces stands behind all of their manufactured products with a standard three-year warranty and guaranteed long-term product support. Pricing and availability information is supplied on their web site www.pickeringtest.com
