Rohde & Schwarz NRP-Z221 Two-Path Diode Power Sensor

Manufacturer: Rohde & Schwarz
Model Number: NRP-Z221
The R&S®NRP-Z221 two-path diode power sensors combine all key characteristics relevant for their use in production: They are cost-effective, fast, precise and USB-capable. The sensors support the same measurement functions as the R&S®NRP-Z11/R&S®NRP-Z2x/R&S®NRP-Z31 three-path diode power sensors and offer the best price/performance ratio in their class. The two-path diode power sensors use the tried-and-tested technology of the three-path diode power sensors. With two overlapping diode paths measured in parallel and a wide dynamic range of 80 dB, the power sensors feature high measurement accuracy and speed. 2-path USB power sensor for universal use, 10MHz to 18GHz, 1nW to 100mW, N(m) (accessory)
