Copper Mountain Technologies (CMT) has released the PE0312-75, a port extender that expands the company’s product portfolio for 75 Ω test applications. The port extender enhances the flexibility of multi-port testing for broadband, telecom, cable, and RF research and production applications in 75 Ω environments. The PE0312-75 is a USB-controlled, 12-port extender, or switch, designed […]
Rigol oscilloscopes reach 13 GHz bandwidth
The DS8000 series features four 4-channel models with bandwidths from 6 GHz to 13 GHz. Rigol has introduced the DS8000 series of digital oscilloscopes. The series takes over as the company’s high-end line with four models topping out at 13 GHz of analog bandwidth. All models feature four analog channels, 40 Gsamples/s sample rate, 500 […]
R&S digital multimeters feature 5.5 and 6.5 digits with triple displays
The UDS series from Rohde & Schwarz provides the company with a significant upgrade and place it against top competitors. Digital multimeters (DMMs) are a measurement staple, sitting alongside oscilloscopes, power supplies, and waveform generators on just about every engineer’s bench. You may not think of Rohde & Schwarz as a major competitor in the […]
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 […]
Oscilloscope software automates automotive ASA-ML serial link tests
QPHY2-ASA software from Teledyne LeCroy lets you perform physical-layer tests on ASA-ML v1.1 devices. SerDes devices transfer data from sensors and cameras to an in-vehicle processing unit, which then sends instructions to the motion systems that drive autonomous vehicles. Teledyne LeCroy has released the QPHY2-ASA oscilloscope software, which automates testing of the Automotive Serdes Alliance […]
Swapfest May 2025: test equipment
The May 2025 gathering of the monthly electronics “Flea at MIT” swapfest featured an excessive number of test instruments. We break them down into oscilloscopes, meters, and signal sources. Click on any image to enlarge in a new tab. Oscilloscopes A Tektronix analog modular oscilloscope. The black bezel hides the model number. This unit has […]
Modular tester simulates and tests control systems
The Pulse Real-Time Target Machine from Swiss company Speedgoat uses a set of I/O modules so you can configure s test system that meets your needs.
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 […]
OFC 2025: Test equipment
This year’s OFC in San Francisco featured one thing, or so it seemed: 1.6T. Every company making optical modules was showing them lest they be left behind in the always accelerating data rate race. As with any emerging technology, test equipment must lead the way. After all, how do you know if anything works unless […]
Phone chargers produce EMI: We compared four
The switching power supplies that regulate output voltage produce radiated emissions. Our tests compare waveforms that give clues as to how the chargers operate.
