Selecting a Power Sensor

LB5900 Sensors are Platform Independent (Linux etc). All sensors compatible with Win XP, 7, 8 & 10; 32 & 64 bit

We cover the RF and Microwave Power Measurement market with three types of USB power sensors. Our True RMS Sensors provide accurate, fast True RMS measurements. LadyBug Peak & Pulse sensors accurately make statistical measurements such as Peak and Pulse Power, Duty Cycle and Crest Factor. In addition to these measurements, our Pulse Profiling sensors offer triggered pulse measurements and statistical functions including CDF, CCDF and PDF measurements along with time domain trace visibility.

For quick, accurate average power measurement of any signal, consider one of our True RMS Sensors, these products are some of the best sensors on the market today and can deliver 2,000 measurements per second. And remember, our patented NoZero NoCal technology means that you do not need to zero the sensors before use, simply connect and measure, even for high accuracy at very low power levels.

All of our sensors feature USB 2.0, and optional external trigger in & out plus recorder out, all without external components. Our patented NoZero NoCal technology make these sensors ideal for test systems and other embedded applications. No need to switch the signal out to zero or calibrate the sensor, or to wait for internal circuitry, just measure. This can save thousands of dollars in switches, sources, and other components. We provide detailed specifications with a variety of example measurements from our sensors in the Using Ladybug Sensors section. Click the links below for more information.

  • True RMS Sensors 9 kHz to 40 GHz
  • HIGH ACCURACY ON ANY SIGNAL WITH ANY MODULATION


    LadyBug True RMS Average Power Sensors deliver reliable, accurate power measurements for CW, Pulse, and modulated signals. These diode based sensors feature a wide dynamic range and a great VSWR. The optional external triggering input feature can be used without any external components. Recorder and Trigger outputs are also available. Our patented NoZero NoCal technology make these sensors ideal for calibration systems, automated test stations and other embedded applications.

    True RMS RF Power Sensors
  • Peak, Pulse and Averaging Sensors 10 MHz to 20 GHz
  • STATISTICAL PULSE & FAST AVERAGE MEASUREMENTS


    These sensors provide quick and easy measurements of pulse power, continuous wave power and other signals. Many of our competitors claim to measure pulse power, however you must input your duty cycle and the power is calculated based on that. Our sensors offer trigger based measurements and the pulse itself is examined giving better measurement uncertainty. There is no need to input the duty cycle to calculate pulse measurements, our sensors measure it.
  • Wideband Pulse Profiling Sensors 50 MHz to 20 GHz
  • VISUAL TIME DOMAIN PULSE PROFILE, PULSE & FAST AVERAGE MEASUREMENTS


    LadyBug wideband Power Sensors feed power waveform samples into high speed A/D converters. The measured power is processed and then delivered as required by the user. These sensors are capable of delivering everything from basic power, to time domain scope-like profiles of the modulated waveform, such as the pulse shown at right. Multiple time gated measurements, crest factor, pulse power, and statistical measurements are all possible with these sensors.
