Two-path Diode RF Power Sensors

16 November 2011 — The new R&S NRP-Z211 (up to 8 GHz) and R&S NRP-Z221 (up to 18 GHz) two-path diode power sensors from Rohde & Schwarz offer high measurement speed and accuracy for a price-sensitive market. Power measurements over a dynamic range of 80 dB (-60 dBm to +20 dBm) are now possible for both CW and modulated signals.

The sensors are based on the proven and patented multipath technology from Rohde & Schwarz. The overlapping diode paths are measured in parallel. They are weighted in the transition range to ensure a smooth transition between measurement paths and eliminate differential nonlinearity. In addition, the user does not have to switch paths, since both diode paths are measured in parallel. This increases measurement accuracy and reduces measurement times.

The new power sensors can be operated on the R&S NRP2 base unit and on virtually all signal generators, spectrum analyzers and network analyzers from Rohde & Schwarz. Moreover, in combination with the R&S NRP-Z4 USB adapter, the sensors can be used directly with a PC.

The R&S NRP-Z211/-Z221 two-path diode power sensors are now available from Rohde & Schwarz.
