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.
Key Facts• Measurement range: -60 dBm to +20 dBm (1 nW to 100 mW)
• Frequency range: 10 MHz to 18 GHz
• N connector
• Best price/performance ratio in its class
• 80 dB dynamic range for CW and modulated signals
• Two-path diode power sensor with enhanced inter-range performance
• Continuous average, burst average, timeslot average, time gating and trace mode supported (video bandwidth 50 kHz)
• Automatic burst detection and acquisition
Supported DevicesThe R&S®NRP-Z221 sensor can be connected to latest-generation of signal generators, spectrum analyzers and network analyzers. This allows you to directly display the average power measured with the sensor without the need for an R&S®NRP2 base unit or PC. This also provides a simple solution for automatic level correction in a signal generator. The spectrum analyzers use the measured power as an absolute reference for increasing the measurement accuracy.
