625-MS/s 16-Bit AWGs Three new M4i.66xx Series AWGs offer one, two, and four channels with each channel capable of outputting electronic signals at rates of up to 625 MS/s with 16-bit vertical resolution. Based on the vendor’s M4i Series PCIe platform, the products are smaller than conventional instruments and can be used in most modern PCs.

The frequency range and dynamic performance of these AWGs make them of interest to engineers and scientists working in areas such as communications, radio, radar, semiconductors, nanotechnology, media testing, automation, ultrasound, optics, and medical and biological science. Spectrum

SMT inductors With mounted height profiles of 1.0 mm to 3.2 mm, a family of six new ultralow-profile SMT shielded inductors is suitable for mobile computing, home automation, portable POS, and other handheld applications.

Offering good EMI performance, these inductors have core geometries and construction that enable high currents with no radiated magnetic fields to interfere with associated components. The family consists of six series of parts: the PA4330, PA4331, PA4332, PA4333, PA4334, and PA4335, which vary by footprint, current rating, and inductance range. Pulse Electronics

PXI solid-state multiplexer The Model 40-681 multiplexer features a range of selectable switching configurations, and the versatility of its architecture allows all multiplexer banks to be interlinked and common connections used as extra signal inputs programmatically. This multiplexer is useful where a high-density MUX array is required that can adapt to different test configurations for different test targets or where a test system may need to be reconfigured in the future.

The use of high-performance solid-state relays ensures that the 40-681 MUX has a long service life even when hot switching into capacitive loads. It can sustain 1.5 A for 100 ms on hot or cold switching. Pickering Interfaces

10-kV pick-and-place handler A high-voltage conversion kit enables the MT9510 pick-and-place handler to test high-voltage applications up to 10 kV (peak). The high-voltage solution will be deployed for the automotive (hybrid car) market and consumer applications.

The high-voltage setup uses a stand­ard MT9510 base unit. All application-specific requirements are covered with the design of the dedicated high-voltage conversion kit to provide flexibility at the test floor, best return on investment, and lowest cost of test. With its favorable cost structure, the MT9510 high-voltage solution also meets the targets of more cost-sensitive applications in the consumer market. Multitest

GNSS production test option The R&S SMBV-P101 option equips the R&S SMBV100A vector signal generator for speed-optimized production test of GNSS modules and receivers. The GNSS production tester simulates separate satellites for the GPS, Glonass, BeiDou, and Galileo navigation standards in the L1/E1 band specifically for these production tests. The four satellite simulations can be activated individually, each with a high dynamic range of 34 dB.

Level changes can be made on the fly without interrupting the signal, enabling users to simultaneously perform independent sensitivity tests for each navigation system. The 1-PPS (pulse per second) or 10-PPS GNSS marker allows exact time synchronization between the tester and the DUT. Pure, level-stable CW signals also can be generated to calibrate the test setup or simulate interferers. Rohde & Schwarz

DC/DC converters The PH-A280 Series DC/DC power modules operate over a range of DC inputs from 200 to 425 VDC while offering 3.3-V, 15-V, and 28-V outputs. The supplies serve industrial, smart-city, and test-and-measurement applications.

The six new PH-A280 power modules are available in three output power levels: 75 W, 100 W, and 150 W. The complete product family encompasses nominal output voltages of 3.3 V, 5 V, 12 V, 15 V, 24 V, 28 V, or 48 V, adjustable by -20% to +10% (±20% for 5-V output models). Efficiencies of up to 90% are achieved, an improvement of 5% over the prior PH Series versions. TDK

SIGTRAN test suite
The enhanced SIGTRAN Protocol Test Suite for Hybrid Networks enables the MAPS protocol test simulation platform to support SIGTRAN (SS7 over IP) and ISDN SIGTRAN (ISDN over IP). Some of the common MAPS features supported across all SIGTRAN protocols include scripted call generation and call reception, ready-to-use scripts for quick testing, and a script-based and protocol-independent software architecture.

The enhanced SIGTRAN Protocol Test Suite now provides an enhanced feature-rich MAPS framework, which includes user-defined statistics, video traffic support, voice-quality scores, and command line interface (CLI) functionalities. Using CLI, all of GUI functions can be controlled by various TCL, Python, VBScript, Java, and .Net clients. GL Communications

RF signal and sweep generator
The SynthNV programmable 34.4-MHz to 4.4-GHz software-tunable RF signal and sweep generator includes a built-in RF power detector. It is controlled and powered from any device running Windows, Linux, or Android OS via a USB port. The included onboard RF power detector can be used as a generic RF power meter or combined with the SynthNV’s sweep function to create a basic RF network analyzer. When the RF signal generator frequency is set, RF power can be measured in less than 400 μs. The SynthNV design also includes nonvolatile memory so it can be programmed to wake up with any frequency, power, sweep, and modulation setting. Saelig

DC electronic load
The ELR9000 Series DC electronic load features an integral, grid-synchronized inverter designed to return up to 94% of the load test energy back to the grid. The rack-mounted unit is available, off-the shelf, with output ratings of 3.5 kW, 7 kW, and 10.5 kW—scalable to 105 kW.

The ELR9000 Series offers four common regulation modes: constant voltage, constant current, constant resistance, and constant power. The FPGA-based operational controls include a function generator and a table-based regulation circuit for the simulation of nonlinear internal resistances. The vendor’s PowerStar 6 software package enables the creation of test routines using a drag-and-drop menu where coding can be performed without programming. Intepro

EMI receiver option
Real-time spectrum analysis (RTSA) now is available as an option for the vendor’s standards-compliant MXE EMI receiver. Adding RTSA to an MXE enables test labs to observe and diagnose transient and wideband emissions during EMC compliance and precompliance testing.

With RTSA, engineers can more easily see and understand high-speed transient signals that are difficult to capture with traditional spectrum or signal analyzers. This is especially useful in applications such as radar, automotive, and wireless communications that often experience fast-moving, short-duration emissions. Keysight Technologies
