USB-5681

The USB-5681 RF power sensor can accurately measure average power from 10 MHz to 18 GHz over 60 dB of dynamic range. The USB-5681 uses a dual-path architecture that provides RMS measurements across the entire frequency and dynamic range. The USB-5681 has the following features:

  • Ability to make average power measurements for continuous wave, multitone, and digitally modulated signals
  • Auto-averaging or repeat averaging methods
  • Auto-range feature
  • Typical sample rate of 140 kS/s
  • Configurable aperture time from 0.01 ms to 300 ms, in 0.01 ms steps
  • Configurable duty cycle correction, to assist in calculating the pulse power of pulse-modulated signals
  • Internal and external triggering options, including configuration settings for trigger delay and external trigger noise immunity
  • Time slot and scope measurement modes
  • Programmatic zeroing of the sensor
  • Onboard calibration factors and correction data, so no reference calibration is needed
