    RF detector power meter

    i started this post because i find many website selling RF-detectors@50GHz@300$. On the other hand all power meter are compatible with their own sensor dependent. So i just wanna know that which device is to be used with Rf-detector to measure power

    RF detector power meter

    I have old HP3582A (0.02Hz to 25.6KHz) spectrum analyzer. I will use with it and update the results

    RF detector power meter

    Thanks It mean both oscilloscope and voltmeter can be used with RF-detector to measure power. Which one is better

    RF detector power meter

    What is difference between RF-detector(Schottky diode detectors) and RF power meter. RF detectors are cheaper so can they be used with voltmeter/oscilloscope as an alternative to power meter. Thanks

    TRL calibration for Free Space Measurements

    I want to perform TRL calibration for free space dielectric measurements. Consider the two antennas that are 30cm apart. I am confused i) THRU:: now do i need to set "zero length delay" in VNA calibration kit (i.e. default setting in VNA). Or i need to set delay corresponding to 30cm. ii)...

    Frequency extension for Spectrum/Network Analyzer

    @ jiripolvika I know there are many companies making harmonix mixer but only for mmwave region (>50GHz). not for very low frequencies.

    Frequency extension for Spectrum/Network Analyzer

    Is there any way to increase the frequency range for spectrum and network analyzer. I have HP3582A (0.02Hz to 25.6KHz) and Anritsu Network analyze of 30MHz range.
