Vishay Intertechnology, Inc. introduced two new series of Automotive Grade 3.3 V to 36 V ESD protection diodes in the SOT-23 package. Offering low thermal resistance, the single-line VGSOTxx and two-line VGSOTxxC series ensure more efficient heat dissipation than the previous generation GSOTxx / xxC devices, allowing for a more robust design that enables higher peak pulse power […]

FieldDAQ captures physical data close to the sensor
FieldDAQ modules accept sensors directly and send data over Ethernet. Collecting data such as temperature, strain, and other physical parameters often requires long sensor wires or rugged equipment close to the measurement source. Long wires can add errors due to losses in analog wiring or from outside interference. Field installations often add environmental and power […]
Teardown: HP 8112A pulse generator
This 50 MHz pulse generator was built as solid as a rock. It’s almost all metal. We take the unit completely apart and look at it from a system and board level. On a visit to the MIT swapfest in 2024, I came across an HP 8112A 50 MHz pulse generator. For $20, I brought […]
15 W PXI programmable resistor modules simulate sensors
These modules let you perform HIL testing for industrial, automotive, medial and other products.
Data-acquisition recorder gets 1500 VDC module
B+K precision adds a 4-channel, ±1500 VDC input module to its DAS1800 data recorder. Today’s electric vehicles operate at voltages approaching 1000 VDC, engineers need to monitor and record those voltages during tests. to that end, B+K Precision has added the D18-HVM4 high-voltage, 4-channel input module to its DAS1800 modular data recorder. The D18-HVM4 adds […]
What is an instrument driver and why do I need one?
Instrument drivers take some of the sting out of controlling test instruments by adding an abstraction layer. Almost everyone who uses computers has had experiences with drivers, and probably not good ones. In the olden days, if you had wanted to hook an old printer up to a new computer, you would have searched through […]
I’ve got the measurement blues again
Back from a three-year hiatus, I’m covering test and measurement again. This time, it’s for EE World.
Engineer ambitiously or be acquired?
Emerson Electric makes a significant offer to acquire NI, which is fighting back.
BNC interface lets piezoelectric sensors hook up to data acquisition gear
A new interface allows the use of IEPE sensors on all data acquisition devices with a 1-MΩ BNC interface. The TA487 IEPE Signal Conditioner is a simple adaptor that allows any PicoScope or oscilloscope to capture and measure signals from a large selection of piezo-electric IEPE sensors, such as the Pico Technology TA095 accelerometer. Integrated […]
ATEasy gets a facelift for 2021
The test programming environment also adds usability features and 64-bit support.
