Rohde & Schwarz NRT Power Meter

Directional power meters are connected between source and load and measure the power flow in both directions.The power applied to the load and the reflection can thus be measured.

Compared to low-cost instruments, power meters like NRT provide a number of benefits:most importantly high measurement accuracy through excellent directivity and a measurement method that determines the average power like a thermal power meter.
The instruments thus provide correct measurement results even in case of modula ion or in the presence of several carriers.Power Sensors NRT-Z43/-Z44 feature low insertion loss, very good matching and excellent intermodulation characteristics:the signal to be measured is virtually unaffected, the sensor is fully transparent.

• Choice between average power, average burst power, peak envelope power (PEP)and peak-to-average power ratio (crest factor)
• Switchover between forward power and absorbed power
• Measurement of power differences in dB or %
• Choice between return loss, SWR, reflection coefficient and reverse-to-forward power ratio in %in reflection measurements
• Display of amplitude distribution (CCDF)for modulated signals
• Consideration of cable loss between sensor and load
• Acoustic SWR monitoring
• Indication of maximum and minimum values
• Quasi-analog bargraph display
• Choice between measurement at the source or at the load
