RF components such as connectors, cables, antennas, and PCB traces need characterizing so you know how they will perform. That’s where a vector network analyzer (VNA) can help. Signal Hound, well known for its USB spectrum analyzers, has introduced the VNA400, a 40 GHz VNA that connects to and gets power from its single USB-C […]

AOC 2023: Exhibits show the latest in military wireless
Washington — The Association of Old Crows (AOC) held its 60th annual convention in Washington during the week of December 11, 2023. EE World was there on December 12. Here is some of what we saw in the exhibit hall. AOC is a defense-oriented conference that focuses on military wireless communications. In addition to product […]
IMS 2023 roundup: test equipment
Test equipment plays a major role in product development and production, which was apparent at IMS 2023. In the photos and videos below, you’ll get a taste of test developments at RF, mmWave, and sub-THz frequencies. This year, D-band (110 GHz to 170 GHz) seized a larger portion of the exhibit hall than in past […]
Spectrum analyzer includes 10-Gb Ethernet SFP+ port, features 43.5 GHz bandwidth
The Signal Hound SM435C 43.5 GHz, high-performance spectrum analyzer and monitoring receiver includes a 10-Gigabit Ethernet SFP+ port, enabling the SM435C to communicate with a PC over long distances using a fiber optic cable. Designed for remotely-located accurate RF data analysis at the lowest cost possible, the SM435C also includes a signed calibration certificate and […]
Five key considerations for spectrum analyzers
A bevy of specifications define how spectrum analyzers perform. But just a handful of qualities can be pivotal when it comes to selecting instrumentation. Contributed by Signal Hound As wireless technologies pervade our lives, more engineers find they must make RF measurements. In the past, RF testing required the use of expensive equipment handled only […]
Spectrum analysis software includes noise figure analysis mode
A new Noise Figure analysis mode is available for the Spike spectrum analyzer software. Noise Figure analysis is one of the most useful metrics for RF test engineers, characterizing the noise contributions of an electrical system, as well as the individual electrical components within the system. Spike is Signal Hound’s spectrum analyzer software, compatible with […]
Book Review: Create Your Own EMC Troubleshooting Kit
Create Your Own EMC Troubleshooting Kit (Volume 1): Essential Tools for EMC Troubleshooters by Kenneth Wyatt shows you the tools you need to start tackling interference problems. Tracking down and mitigating electrical interference isn’t black magic, though some would have you believe that. Armed with some knowledge on how signals travel and with the right […]
Economical vector signal generator features 40 MHz bandwidth
The VSG60A vector signal generator offers the performance and agility of a serious vector signal generator at a fraction of the cost. A low phase noise, agile local oscillator with a 200 μsec switch time enables frequency hopping spread spectrum testing, and a dual 14-bit DAC runs at 2x or 3x the I/Q symbol rate […]
Spectrum analyzer features 20 GHz bandwidth, 160 MHz IBW of calibrated I/Q capture
The new SM200B spectrum analyzer offers 160 MHz instantaneous bandwidth (IBW) calibrated I/Q capture, available through block transfer of a two-second I/Q buffer over USB 3.0 to the PC. This added 2-seconds of segmented I/Q capture memory, with advanced triggering options such as frequency mask triggering (FMT) plus user-specified pre- and post-trigger, satisfies the ever-increasing […]
Modules let spectrum analyzers serve as I/Q sources within open-source GNU radio apps
GNU Radio modules for the BB60C and SM200A spectrum analyzers allow the analyzers to be used as I/Q sources from within GNU Radio, as blocks in a flowgraph, components of a hierarchical block, or called from a script. According to Roger Rush, lead developer on the project, “Signal Hound and GNU Radio share a software-based […]
