USB Test: Bright Spot on a Dim Landscape
By Richard Hawkins, President
LadyBug Technologies

Liam Devlin, CEO, Plextek RF Integration

“Sequestration,” the brainchild of the federal government, has proven damaging to both our nation’s defense readiness and to many companies serving our sector.

Despite this, the field of USB test instrumentation has remained a bright light on a dimmed business landscape, as it offers engineers and test personnel the prospect of convenient, cost-effective, and entirely portable test capability rivaling the specs of traditional, heavyset test “boxes.”

Why is the field of USB test healthy? Functionality, small packages, ease of use, and user-friendly pricing. In the past, one had to purchase separate instruments to perform pulse profiling, CW, peak power meter measurements. Today it is possible to get this functionality in a single package. This enables a reduction in overall instrument size, which in turn reduces the power requirement. In the past, a box instrument would have a dedicated power supply, and now all necessary power comes via a standard USB cable. In years gone by, one would face a cost of many thousands of dollars for capability that today is available for around $2,000.

Smaller, More Capable
Customers today can take advantage of physically smaller packages offering greater capability. Ladybug USB power sensor offers an all-in-one solution: average, pulse, and peak power capabilities. This is possible now as a result of improvements in processor speed. Pulse profiling, average, peak and pulse power measurements can now be produced in a smaller package.

Signaling the convenience available today, LadyBug also offers custom sensor/attenuator combination packages. The sensor and attenuator are characterized together after final calibration to offer superior performance and accuracy. The product is delivered with a calibration table along with the sensor’s certificates. The attenuator and sensor sets are available on any of LadyBug’s sensors, including its True RMS, Peak & Pulse, and Pulse-profiling sensors. Typical applications include high-power measurement, manufacturing test, OEM inclusion, ATE systems, and labs.

Adding to that convenience and capability, LadyBug Technologies’ Enhanced Virtual Power Meter V4.5 now provides an ideal user interface for measuring a host of RF signal parameters. Included with LadyBug’s exclusive line of Peak and Pulse Power Sensors, this product makes it unnecessary to provide assumed duty cycle to achieve accurate pulse measurements. Pulse Power, Duty Cycle and Crest Factor are all available effortlessly with LadyBug’s VPM/Sensor combination.

Tips for First-Time Buyers
A helpful tip for first-time buyers trying to decide among today’s USB power sensor offerings: when it comes to manufacturer claims on “measurements per second,” look more closely. There’s a big difference between taking measurements on the one hand, and making them available to the user of the power sensor on the other. Are these claimed measurements per second actually available to you in real time, or is a buffer-induced delay involved? Unlike many competitors, LadyBug Technologies’ power sensors feature zero buffer-induced latency, meaning that our 2,000 measurements per second are yours in real time.

Secondly, take note of “zeroing” and calibration when weighing your power sensor choices. Does the USB power sensor you are considering require disconnection for zeroing and calibration prior to each use, thus taking up more of your valuable time and adding costly components? With LadyBug’s patented No-Zero, No-Cal™ power meters, that expensive, time-wasting step is eliminated.

FROM WHERE WE SIT

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
