The PXI Vector Signal Transceiver (VTS) Radar Target Generation (RTG) system unlocks closed-loop, low-latency, real-time radar test capabilities. The new PXI VST allows engineers to identify and isolate issues before costly open-air range tests, increasing user confidence in radar system performance with accurately calibrated radio frequency (RF) test capability. Today, radar test engineers must test […]

Portable sensor signal simulator/calibrator features Wi-Fi connectivity
The 1520 Signal Simulator and Calibrator offers market-leading Wi-Fi operation, ergonomic design and advanced visualization features and up to 10 hours of battery life. The NIST-traceable signal source is designed to provide laboratory-grade precision to in-the-field simulation of a range of sensors. The 1520 user interface makes it easy to simulate a wide variety of […]
Vector signal generators get 56 GHz and 67 GHz options
The R&S SMW200A vector signal generator is first to enable flat frequency response and 2-GHz modulation bandwidth above 44 GHz. In addition to all applications already supported up to 44 GHz, the 100 kHz to 56 GHz option covers all currently used 5G frequencies, plus earth-to-satellite applications. The 100 kHz to 67 GHz option also […]
Dual-channel digitizers provide synchronous 3.2 GS/sec, 12-bit sampling on each channel
A new dual-channel digitizer provides synchronous 3.2 GS/sec, 12-bit sampling on each channel. This means no data needs to be lost, even when the card is acquiring data with both channels running at their maximum sampling rate. The ultrafast bus allows all the data to be transferred directly to PC memory for storage, or even […]
Signal generator delivers up to 13.6 GHz with high signal purity. low phase noise
The DSG3000B Series RF Signal Generator offering high purity signal generation and modulation. The DSG3000B is available in 6.5 and 13.6-GHz models with optional built-in IQ baseband generator and OXO timebase with standard AM/FM/ØM analog modulation up to 3.6 GHz, and I/Q modulation and I/Q baseband output up to 6.5 GHz. RIGOL’s new DSG3000B RF […]
Can something consume energy without emitting a field?
The editorial offices of Testandmeasurementtips.com recently received a letter from an individual who headed up a group of investigators of paranormal phenomenon. It was a serious letter. To summarize, the group had concluded there was no legitimate method to record the activity of an alleged haunting. But the writer did have a question for us, […]
Radio altimeter flight-line test set adds fiber optic delay
The ALT-9000 universal radio altimeter (RADALT) flight line test set adds fiber optic delay to traditional radio frequency (RF) testing, enabling it to test all types of RADALTS on the market today. The RADALT measures an aircraft’s altitude above the terrain, by transmitting a radio frequency (RF) signal down to the ground and receiving a […]
Hand-held spectrum analyzers come in 1.3 and 2.7-GHz versions
The Aim-TTi PSA Series 3 RF Spectrum Analyzers are available in 1.3 GHz and 2.7 GHz versions and have long battery lives with improvements over the previous Series 2 instruments, even rivalling more expensive handheld RF products. Improvements include a lower noise floor for increased sensitivity, a new frequency counter, additional RMS, Sample, and Average […]
How big is the band gap? A heated discussion
There’s a trick with a soldering iron that can be used to determine whether an unidentified semiconductor is n-type or p-type. In essence, it determines whether the majority carriers are holes (p-type) or electrons (n-type). Just as heat makes a gas expand (PV=nRT), the hot tip of a soldering iron makes carriers expand away from […]
Test setup simulates, characterizes, validates PCIe designs
An end-to-end PCIe test solution enables the simulation, pathfinding, characterization, validation and compliance testing of PCIe designs. To maintain performance goals and prepare for the PCIe 6.0 move to pulse amplitude modulation 4-level (PAM4), customers need a smooth transition from PCIe 5.0 to 6.0, where the integrity of PCIe measurements are backed by leading-edge tools […]
