Every Measurement Starts with a Trigger

As today’s products in consumer electronics, automotive, and aerospace applications get more complex with every generation, the requirements on test instruments increase even more because test capabilities need to advance, while test times and time-to-market are expected to decrease.

One important requirement for instruments like oscilloscopes is the ability to detect and trigger on an event of interest within a stream of unsuspicious signals fast and reliably. The quicker a specific event can be detected, the faster a problem in an electronic design can be debugged, reducing development and manufacturing test times.

Using Hardware Handshaking to Reduce ATE Test Times

Developing an automatic test equipment (ATE) system takes time, and there can be different approaches to achieve the same goal. Without the right approach, the system can become less efficient, contributing to more time spent or more resources used to complete the task.

With advances in technology, ATE systems are becoming more widely used across a range of industries including manufacturing, avionics, aerospace, military, and defense. ATE systems are efficient and can be incredibly useful, allowing quick and accurate testing that communicates across a set of devices. However, it can become a complicated task to properly set up an ATE system to achieve the user’s desired outcomes.

Motion Controller Automates Hydrostatic Pressure Testing

A flexible hydrostatic test system for the oil and gas industry must precisely measure a wide range of pressures. Because the items tested vary widely, most testing is done manually. A test engineer sets appropriate parameters, and a skilled operator adjusts the pumping system for the specimen under test. After the technician sets up the test, he or she is usually seated at the pressure source and controls the specified pressure. The human interaction lacks precision and repeatability; each time the test is performed, there is a variation in results. In extreme cases, the maximum rated pressure is exceeded, causing damage.

Surface Measurement

AMETEK Taylor Hobson (Leicester, UK) offers the Surtronic Duo surface measurement system, which consists of the Surtronic R-Series roundness and form tester (for bearing parts) and the Surtronic S-100 portable roughness tester with USB connectivity. The instrument uses a diamond stylus that is drawn across a part with a motorized traverse mechanism. Vertical movement of the stylus is detected by a piezoelectric pickup that converts mechanical movement into electrical signals. The signals are digitized and sent to a microprocessor for calculation of surface parameters. One-button operation produces a full set of traceable measurement results, including a detailed profile graph. Display and traverse modules can be operated as one unit or separated for difficult-access applications; Bluetooth connectivity allows wireless communication between them.

Carbon Monoxide Monitors

The AQM-103 series of carbon monoxide monitors from OMEGA Engineering (Stamford, CT) are designed to measure CO concentration, humidity, and air temperature. The CE-compliant devices feature a large LCD display that shows CO level, humidity, temperature, date, and time with programmable high alarm and audible/visible LED warning light for high CO concentration. This monitor is suited for indoor air quality (IAQ) diagnosis and HVAC system performance verification.

Electronic Micrometer

Paul N. Gardner Co. (Pompano Beach FL) introduced the Fowler Xtra-Value II electronic micrometer with a choice of measuring range, and an LCD with an inch/metric switchable resolution. A switchable resolution of 0.00005" and 0.001 mm, and an accuracy of 0.00016"/0.004 mm, are provided. Carbide measuring faces provide long life and wear resistance. A ratchet thimble applies consistent force for repeatability between users. The instrument features direct RS-232 output, and absolute and incremental modes.

Source Measure Unit

Yokogawa Corporation of America (Sugar Land, TX) introduced the GS820 multi-channel source measure unit (SMU) that features isolated 2-channel source and measurement functions. The unit sources up to 50 Volts and 0.6 Amps DC, and offers four-quadrant operation consisting of current source and current sink operation. On the 50V model, voltage ranges are 200 mV, and 2, 20, and 50 Volts. Current ranges are selectable from 200 nano-Amps to 1 Amp.

Digital Transceiver

The V616 digital transceiver from Innovative Integration (Camarillo, CA) supports one or two plug-in modules, each featuring four independent channels of DDC, two DUC, and one spectrum analyzer embedded in the Xilinx Virtex-6 FPGA. It allows users to monitor the wide-band or narrow-band spectrum and record the data directly from the ADCs or down-convert the channels modulated on the IF band. The embedded PC supports contiguous recording at 2,000 MBytes until running out of disk space. The transmitter can play a recorded baseband waveform of independent bandwidth, and up-convert and modulate it on the IF band on the DACs. Each DDC/DUC has its own programmable tuner, programmable low-pass filtering, gain control, and decimation/interpolation setting, supporting independent channel bandwidths up to 100 MHz.

Vector Network Analyzer

Keysight Technologies (Santa Rosa, CA) announced a new capability that adds a high-performance spectrum analyzer to the PNA and PNA-X Series of microwave vector network analyzers (VNAs). This capability reduces test times and simplifies system connections. It adds high-speed spurious measurements in the instrument used to characterize S-parameters, compression, and distortion in satellite equipment, defense electronics, and commercial wireless devices. The VNA can perform simultaneous spectrum measurements on all test ports, and enables one-connection characterization of mixers, converters, amplifiers, modules, or subsystems. Example measurements include LO, RF, and IF feedthrough; harmonics; intermodulation products; and other higher-order mixing products.
