LadyBug Technologies USB Power Sensors and their Specifics

by Ladybug

Use of RF and microwave frequencies for digital communications, radar and many other technologies has been increasing at a dramatic rate. The development of these products often requires significant testing due to the complexities. Accurate power measurements is one of the most important requirements of the RF and microwave product development. This requirement is easily met by LadyBug USB power sensors. These power sensors are designed for measuring peak and pulse power as well as average power. What are the different types of power sensors provided by LadyBug Technologies? What are the typical features of these power sensors? This post answers these questions.

Get Introduced to LadyBug Technologies USB Power Sensors

LadyBug Technologies provides three types of USB power sensors for a wide power frequency ranges. An in-depth understanding of the following power sensors will make the selection process easy for you.

  1. True RMS Sensors — from 9 kHz to 40 GHz: Often referred to as RMS responding, these sensors are designed to deliver the highest accuracy on modulated, CW, and pulse signals, with any modulation such as 400MHz bandwidth. True RMS Sensors are diode-based. Ladybug sensors are empowered with No Zero No Cal technology which makes them an ideal choice for embedded applications, automated test systems, calibration systems, as well as general purpose applications. The following features of these sensors have contributed to their popularity.
  • Frequency coverage from 9kHz to 40 GHz.
  • True RMS sensors feature innovative USBTMC and USB HID interfaces. Ideal for ATE or general in LINUX or Windows. (LB5900 series)
  • Standard IVI foundation SCPI command set. (LB5900 series)
  • SPI and I2C interfaces are suited for direct control, embedded and ATE applications. (LB5900 series)
  • The sensors are provided with Power Meter software that combines the measurement capability of sensors with the flexibility and the power of advanced computers.
  • A variety of options is available, including various connectors, internal storage analog output and security.
  • Internal memory enables tracing as well as long-term logging. (LB5900 series)
  • These sensors are useful in research & development as well as several manufacturing and service applications including satellite, radar, and telecommunications.
  1. Peak, Pulse, and Averaging Sensors— from 10 MHz to 20 GHz: These sensors are designed to provide quick measurements of CW and modulated signals, and can directly measure peak and pulse power. The following are a few interesting features of these sensors, which makes them an ideal choice for various radar and pulse measurements.
  • Ladybug’s Peak and Pulse sensors are designed to provide statistical numerical pulse information for repetitive pulses.
  • Can make 2,000+ settled power measurements per second.
  • With the increasing use of microwave communication and radar signals across various industries, fast statistical measurements are becoming an important requirement. Peak and Pulse sensors perform the task by collecting power levels and placing them into buckets, which are statistically processed for quick measurements. During this processing, the peak power is located and reported. Additionally, pulses mesial, proximal, distal and top line levels are located. This detailed information is used by sensors to automatically calculate and report accurate pulse power, duty cycle, and crest factor to the user.
  • The LB479A Peak Pulse and Average Power Sensor is in this category. These sensors are suited for general use systems, ATE systems, lab & field systems, manufacturing testing, as well as other pulse measurements.
  1. Pulse Profiling Sensors— from 50 MHz to 20 GHz: These sensors provide all of the features of LadyBug Peak, Pulse, and Averaging Sensors. The sensors also deliver a time domain trace measurement and triggered pulse measurements. Is that all? No. There are several beneficial features which make these sensors ideal for general use systems, ATE systems, radar and pulse measurements, and so on.
  • The sensor measures RF power delivering fast results.
  • The signal detail can be easily visualized on a screen.
  • Wideband Pulse Profiling sensors are used in combination of Peak and Pulse sensors to make triggered pulse measurements such as pulse repetition and pulse width.
  • These sensors provide full complements of statistical information such as CCDF, CDF, and PDF.

After learning the features and benefits of each of these power sensors, you will be in a better position to decide which is best for you.
