Functionality & Features
- Zero-bias Schottky-diode detector for direct average-power measurement without external bias
- RMS weighting of all spectral components ensures accurate readings on modulated, pulsed, or distorted signals
- Plug-and-measure operation: sensor-specific calibration data stored in internal memory eliminates manual entry of correction factors
- Fast measurement response suitable for automated test environments
Compatibility
- Compatible with Rohde & Schwarz power-meter base units: NRVS, NRVD, URV35, URV55
- Interfaces via sensor head; base unit displays power and handles measurement sequencing, statistics, and remote-control commands
Physical Characteristics
- Compact cylindrical head, approx. 2.6 in L × 1.0 in Ø (67 mm × 25 mm)
- Lightweight: ~ 2 oz (60 g)
- Rugged brass housing with corrosion-resistant finish
Typical Applications
- Calibration labs requiring traceable average-power measurements
- RF component test (amplifiers, filters, mixers) under CW and digitally modulated signals
- Automated production test where rapid, repeatable power readings are essential
- Wireless-device characterization (TDMA, CDMA, W-CDMA, GSM)
