*产品描述

产品总览
罗德与施瓦茨NRV-Z5是一款高灵敏度二极管功率传感器。 R&S NRV-Z5二极管功率传感器基于零偏置肖特基二极管,可将低于1 µW的功率范围降低到100 pW(-70 dBm)的物理极限。在-70 dBm至-20 dBm的范围内,其行为与热传感器的行为非常相似,即精确测量调制信号的平均功率,谐波的RMS加权以及与温度和频率无关的线性度。

NRV-Z5的特性允许在平方律区域之外进行精确的功率测量,功率最高可达20 mW(+13 dBm)。在此区域中,传感器输出信号的高信噪比使得测量时间非常短。但是,应注意,平方律区域之外的高灵敏度传感器的响应与热传感器的响应不同,因此只能测量具有未调制包络(CW,FM,?M,FSK,GMSK)的纯频谱信号。关于显示线性度,由于频率和温度的影响,在该区域中预计比热传感器具有更大的测量不确定性。

R&S NRV-Z5功率传感器的规格包括:
频率范围:100 kHz至6 GHz
功率测量范围:
10 nW至500 mW
2 W(平均)
10瓦(PK)
最大驻波比:
100 kHz至4 GHz:1.05(0.024)
> 4 GHz至6 GHz:1.10(0.048)
零偏移::±5 nW
显示噪音:2 nW
线性不确定度:0.03dB(0.7%)

Product Overview

The Rohde & Schwarz NRV-Z5 is a high sensitivity diode Power Sensor. The R&S NRV-Z5 Diode Power Sensor is based on zero-bias Schottky diodes which open up the power range below 1 µW down to the physical limit of 100 pW (-70 dBm). In this range, from -70 dBm to -20 dBm, the behavior is much the same as that of thermal sensors, i.e. precise measurement of the average power of modulated signals, RMS weighting of harmonics and linearity independent of temperature and frequency.

The characteristics of the NRV-Z5 allow precise power measurements also outside the square-law region up to a power of 20 mW (+13 dBm). The high signal-tonoise ratio of the sensor output signal in this region makes for very short measurement times. It should however be noted that the response of high-sensitivity sensors outside the square-law region differs from that of thermal sensors so that only spectrally pure signals with unmodulated envelope (CW, FM, ?M, FSK, GMSK) can be measured. Regarding the display linearity, greater measurement uncertainties than with thermal sensors are to be expected in this region due to frequency and temperature effects.

Specifications of the R&S NRV-Z5 Power Sensor include:

  • Frequency Range: 100 kHz to 6 GHz
  • Power Measurement Range:
    • 10 nW to 500 mW
    • 2 W (AVG)
    • 10 W (PK)
  • Maximum SWR:
    • 100 kHz to 4 GHz : 1.05 (0.024)
    • >4 GHz to 6 GHz : 1.10 (0.048)
  • Zero Offset:: ±5 nW
  • Display Noise: 2 nW
  • Linearity Uncertainty: 0.03dB (0.7%)
  • Power Coefficient: 0
  • Connector Type: N
