    Leakage......................46 6.6.1 Spurious Response Frequencies The hardware design of the R&S NRQ6 differs fundamentally from a spectrum ana- lyzer. Therefore, the R&S NRQ6 cannot provide a similar level of spurious response rejection. For isolated signals with small bandwidths and correctly specified measure- ment frequencies, that is not a problem.

  • Page 46: Lo Leakage

    For the 3rd harmonic, the image suppression of the left sideband is about 9.5 dBc. For the 5th harmonic, the image suppression of the right sideband is about 14 dBc. The exact value depends on the frequency response of the R&S NRQ6. 6.6.2 LO Leakage In a receiver-based power sensor, signal leakage paths can occur.

  • Page 49: Adapting To The Test Signal

    Automatic Settings 7 Adapting to the Test Signal The R&S NRQ6 is a frequency selective power sensor. Before starting a measure- ment, you need to take the test signal and its properties into account. You can do that either automatically by using the autoset function, or by setting the fre- quency, filter, bandwidth and attenuation manually.

  • Page 50: Frequency Configuration

    The center frequency defines the mixing frequency in the downconversion process. Signals outside of the analysis bandwidth are filtered out. However, the R&S NRQ6 is sensitive to signals at frequencies related to the harmonics of the conversion fre- quency.

  • Page 51: Frequency Adjustment For Narrowband Measurements

    You can synchronize the reference frequencies of the R&S NRQ6 and the signal source. Make sure that center frequency is specified accurately. Use the REF connector of the R&S NRQ6 to lock the R&S NRQ6 to the reference fre- quency of the signal source or vice versa.

  • Page 79: Interplay Of The Controlling Mechanisms

    ® Measurement Configuration R&S NRQ6 Controlling the Measurement Repeating termination control Outputs a measurement result when the entire measurement has been completed. This means that the number of measurement cycle repetitions is equal to the set aver- age count. If the average count is large, the measurement time can be very long.

One measurement lasts as long as the defined aperture time. As defined by the average count, after 4 measurements, the result is averaged and available.
  • Page 81 After 4 measurements, when the average count is reached, settled data are available. When the trigger count is reached (TRIGger:COUNt), the R&S NRQ6 returns to the idle state.
