Page 43: Improving Measurement Results
www.allice.de Allice Messtechnik GmbH ® Measurement Basics R&S NRQ6 Impact of Measurement Parameters on Noise Averaging For non-periodic signals, disable averaging entirely and choose the aperture time according to the desired total measurement duration. This approach is most efficient since it minimizes any waiting or processing times in the sensor. For periodic signals, the measurement result attains its maximum stability for a fixed aperture time.
Page 44 www.allice.de Allice Messtechnik GmbH ® Measurement Basics R&S NRQ6 Impact of Measurement Parameters on Noise Note that the selected resolution bandwidth filter does not influence the measurement noise directly. However, the resolution bandwidth must be small enough so that the noise power is sufficiently below the measured value.

www.allice.de Allice Messtechnik GmbH ® Measurement Basics R&S NRQ6 Potential Sources of Error Figure 6-3: Measurement time for CW signal Figure 6-3 shows the resulting measurement time for a fixed noise contribution of 0.01 dB (2σ), assuming that the filter settling time is far smaller than the integration time and that the noise floor power is much smaller than the power level.

Page 47 www.allice.de Allice Messtechnik GmbH ® Measurement Basics R&S NRQ6 Potential Sources of Error These emissions have the frequency of the local oscillator or a multiple of it, the har- monics. The emissions can lead to mixing products in the DUT. For example if the DUT is a signal generator with level control, the LO leakage of the R&S NRQ6 can lead to a wrong level setting.

Page 49: Adapting To The Test Signal
www.allice.de Allice Messtechnik GmbH ® Adapting to the Test Signal R&S NRQ6 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
www.allice.de Allice Messtechnik GmbH ® Adapting to the Test Signal R&S NRQ6 Frequency Configuration 7.2 Frequency Configuration If you do not use the autoset function, the frequency of the test signal is not automati- cally determined. The center frequency defines the mixing frequency in the downconversion process. Signals outside of the analysis bandwidth are filtered out.

www.allice.de Allice Messtechnik GmbH ® Adapting to the Test Signal R&S NRQ6 Frequency Configuration ● Chapter 13, "Programming Examples", on page 174 7.2.2 Frequency Adjustment for Narrowband Measurements For small resolution bandwidths, oscillator offsets, drifts or phase noise contributions can corrupt the measurement results. Therefore, you have to take additional measures by using one of the following options.

www.allice.de Allice Messtechnik GmbH ® 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.

www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Trigger Settings Example: Average count = 1 [SENSe<Sensor>:]AVERage:COUNt For average count 1, the setting of the termination control has no impact. In both cases, the measurement runs for the duration of one aperture time. Then, settled data are available, and the R&S NRQ6 returns to the idle state.
Page 86: Trigger Sources
www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Trigger Settings ● Measuring The power sensor is measuring data. It remains in this state during the measure- ment. When the measurement is completed, it exits this state immediately. 9.2.2 Trigger Sources The possible trigger conditions and the execution of a trigger depend on the selected trigger mode and trigger source.
Page 87: Hold-Off Time
www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Trigger Settings Figure 9-1: Significance of the dropout time The RF power between the slots is below the threshold defined by the trigger level and the trigger hysteresis. Therefore, the trigger hysteresis alone cannot prevent triggering at B or at C.

www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Correction Settings 9.3.1.2 Zero Calibration In a zero calibration, you determine the correction data for your measurement setup. The R&S NRQ6 performs the following steps. 1. Measures the noise using the signal at the RF input. Therefore: Turn off all test signals before zeroing.
Page 94 www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Correction Settings 3 dB Frequency / Hz In the following example, the inherent noise spectrum in zero-IF mode is shown, with RBW = 100 MHz and attenuator = 0 dB. Fig.9-2 shows the noise spectrum without cor- rections.

This DC offset is caused by the reflection of the internal LO signal at the RF connector, leading to mixing products.
Page 96: Correction Parameters
www.allice.de Allice Messtechnik GmbH ® Measurement Configuration R&S NRQ6 Correction Settings Due to changes in the environmental conditions, it happens that the DC offset value does not fit any more.

www.allice.de Allice Messtechnik GmbH ® Remote Control Basics R&S NRQ6 SCPI Command Structure 14.2.1 Syntax for Common Commands Common (=device-independent) commands consist of a header preceded by an aster- isk (*) and possibly one or more parameters. Examples: *RST RESET Resets the instrument.
Page 181: Scpi Parameters
www.allice.de Allice Messtechnik GmbH ® Remote Control Basics R&S NRQ6 SCPI Command Structure Optional mnemonics Some command systems permit certain mnemonics to be inserted into the header or omitted. These mnemonics are marked by square brackets in the description. The instrument must recognize the long command to comply with the SCPI standard.
Page 182 www.allice.de Allice Messtechnik GmbH ® Remote Control Basics R&S NRQ6 SCPI Command Structure Numeric values Numeric values can be entered in any form, i.e. with sign, decimal point and exponent. Values exceeding the resolution of the instrument are rounded up or down. The man- tissa can comprise up to 255 characters, the exponent must lie inside the value range -32000 to 32000.
Page 183 www.allice.de Allice Messtechnik GmbH ® Remote Control Basics R&S NRQ6 SCPI Command Structure Boolean parameters Boolean parameters represent two states.
