Power Sensor Connects Via USB

The model NRP-Z81 broadband power sensor from Rohde & Schwarz combines an RF detector, analog and digital signal processing, and processing logic in a compact sensor that connects to a personal computer (PC) by means of a USB port. The power sensor features a video bandwidth to 30 MHz and rise time of 13 ns, making it suitable for power measurement of pulsed waveforms. It features a dynamic range of 70 dB and can measure minimum levels to -50 dBm for pulsed signals over a frequency range of 50 MHz to 18 GHz. Average power can be measured over power levels from -60 to +20 dBm. For more information on the USB power sensor, visit the Rohde & Schwarz website at:
