Teardown: HP 8112A pulse generator

May 13, 2025 By Martin Rowe 1 Comment

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 […]

Data-acquisition recorder gets 1500 VDC module

August 22, 2024 By Martin Rowe Leave a Comment

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?

February 16, 2023 By Rick Nelson Leave a Comment

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 […]

BNC interface lets piezoelectric sensors hook up to data acquisition gear

August 24, 2022 By Lee Teschler Leave a Comment

picotech

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 […]

OpenVPX backplanes designed for horizontal-mount enclosures

November 2, 2020 By Lee Teschler Leave a Comment

Backplane for 1U Horiz

New OpenVPX backplanes are designed for horizontal-mount enclosures. The horizontal-mount backplanes can be placed into 1U-4U tall 19-in rackmount OpenVPX enclosures. They provide enough space to have three 3U slots or one 3U and one 6U slot side-by-side. So, a wide range of configurations and size options are available. The backplanes are typically designed to […]

NI CEO: COVID-19 on day one

October 14, 2020 By Martin Rowe Leave a Comment

NI CEO Eric Starkloff’s first decision was what to do about COVID-19 the night before he took over on February 1, 2020. Since then, he’s seen the opportunities in communications resulting from the pandemic. How would you like to take on a new leadership role just as a pandemic takes hold? That’s what Eric Starkloff […]
