Description
The National Instruments USB-5681 RF Power Sensor Device, with part number 781214-01, is a versatile tool from the renowned manufacturer National Instruments.
Designed to cover an extensive frequency range from 10 MHz to 18 GHz, it caters to a broad spectrum of RF applications. The device can accurately measure input signal strengths between -40 dBm and +20 dBm, with specialized measurement sub-ranges for enhanced precision, including +20 dBm to -7 dBm, and -7 dBm to -40 dBm.
It supports a bandwidth of 50 kHz, which facilitates its use in various scenarios, and boasts a measurement speed of 100 samples per second (S/s), enabling quick data acquisition. The uncertainty in linearity is impressively less than 3%, signifying high reliability in its measurements.
Adherence to safety standards such as IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1 ensures that it meets global regulatory requirements. The device operates efficiently with a power requirement of 5 VDC and 450 mA, sourced directly from the host USB connection.
To protect the equipment, the USB-5681 is designed to withstand a maximum voltage of ±20 VDC at the RF port and can handle an absolute maximum power of +30 dBm. Moreover, it offers flexibility in operation with two modes: hardware-triggered and software-triggered modes, allowing for tailored usage in different measurement environments.
