          WY2288 Digitally RF Millivolt Meter/Low Power Meter(200Hz-1.5GHz)




          WY2288 is a digitally intelligentized radio frequency millivolt meter/ low power meter, able to measure sine voltage’s r.m.s and the relevant power performance, frequency from 200Hz to 1500 MHz. The meter adopts demodulation magnification principle, charactered by a wide frequency response, low SWR, high sensitivity and high accuracy in measuring. Because is the CPU control digital equipment, realize the automatic control range, RS232 interface (option). Is the laboratory, the factory UHF voltage and power testing the necessary instruments.

          1 Features:

          Digitally intelligentized RF voltage meter/ low power meter.  
          Maximum 11000 digitally displayed voltage value, 4-digit displayed power and dBm.  
          LCD screen, simultaneously displays multi-parameters and transformation situations. ?
          Specially designed low voltage measuring adjustment, guaranteeing the measuring accuracy based on < 10mV.

          Coaxial probe configuration to ensure that from <10mV to 5V with good amplitude-frequency characteristics. (See attached Low Level characteristic curve).

          50Ω and 75Ω matching auto-select available.
           
          Option:RS232
