Reviews Frequency Detection Meter

1-600MHz RF Signal Power Meter Logarithmic Detector -74dBm to 18dBm Radio Frequency Detection

  • The detector is is used for RF signal power detection of frequency range between 1MHZ and 600MHZ.
  • It can detect a rf signal of power from -74dBm to 18dBm, and convert the RF signal into a DC voltage output.
  • The higher radio frequency signal range or power is, the higher output voltage will be.
  • output voltage is proportional to logarithm of input signal range.
  • Widely used for RF signal detection, signal power measurement, environment field strength detection, can also be used as a part of automatic gain control and automatic level control.
  • It can be made into 1mw ~ 1kw RF power meter after appropriate transformation.

Decibel Meter, CURCONSA SPL Meter, Portable Sound Level Meter, 30dB to 130dB, LCD Display, can be Used in Homes, Factories and Streets（Blue）

  • ...ter is 30dB to 130dB with fast response speed and stable and reliable performance. Sound level meter is a high-precision noise meter with an accuracy of ± 2.0 dB. Real-time monitoring can give you accurate data on the sound level in the area.
  • ❤【A / C Double-weighting Measurement】 The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C-weighting simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
  • ❤【Fast and Slow Response Rate Conversion】 The spl meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
  • ❤【Maintain the Maximum Value】Long press the MAX key to lock the maximum value measured during the measurement. Note that db meter does not have data logging and saving capabilities. If there is ....
