Page 29 ® Measurement basics R&S FPL1-K30 Measurement modes Performing a manual measurement In manual measurement mode, you have to measure (or calibrate) the hot and cold power characteristics of the DUT separately. When you start the measurement, the application opens a dialog box that allows you to select the type of measurement to perform next.
Page 30: Dut Types
® Measurement basics R&S FPL1-K30 DUT types Clearing results To replace the previous calibration or measurement results, clear the currently stored data using the "Clear Calibration Results" or "Clear Measurement Results" function. Returning to automatic measurement mode When you are in automatic measurement mode and select a noise source with resistor characteristics, the application automatically selects the manual measurement mode.
Page 31: Image Frequency Rejection
® Measurement basics R&S FPL1-K30 Image frequency rejection If you have selected a frequency-converting DUT measurement mode, the layout of the "Overview" dialog box adds the local oscillator to the test setup. The local oscillator can have a fixed or a variable frequency. If the LO frequency is fixed, the intermediate frequency (IF) resulting from the conversion process is variable (depending on the input signal).

Page 33 ® Measurement basics R&S FPL1-K30 Image frequency rejection For mixers whose image rejection is known, define the magnitude of image rejection in dB as accurately as possible. Otherwise, measurement results ("noise figure" and "gain") deviate between 0 dB to 3 dB. If you do not know the image rejection characteristics of a mixer, use a custom test setup including an additional filter.
Page 34: Calibration (2Nd Stage Correction)
® Measurement basics R&S FPL1-K30 Calibration (2nd stage correction) measurement is similar to measurements on a mixer with an average sideband sup- pression. 4.5 Calibration (2nd stage correction) The calibration procedure of the application measures the inherent noise of the R&S FPL1000 you are using.
Page 35 ® Measurement basics R&S FPL1-K30 Calibration (2nd stage correction) If you change the frequency, while the frequency span stays the same or is reduced, the application interpolates the correction data for the new measurement points. A new calibration is not required. However, measurements based on interpolated data can result in an increased measurement uncertainty.

Connect the noise source directly and without a cable to the RF input of the ana- lyzer. 2. Connect the noise source to the +28 V voltage supply (Noise Source Control con- nector) on the back of the R&S FPL1000.
Page 37: Using Smart Noise Sources
® Measurement basics R&S FPL1-K30 Using smart noise sources To achieve a valid calibration by importing a saved one, all parameters of R&S FPL1000-K30 must match exactly to the ones that have been used for the cali- bration. At the import of a calibration, a preview dialog is shown which contains all rele- vant parameters of the calibration to be imported and an indication (green / red) if they match to the current instrument and option settings.
Page 38: Separating Signals By Selecting An Appropriate Resolution Bandwidth
® Measurement basics R&S FPL1-K30 Separating signals by selecting an appropriate resolution bandwidth not be edited in the R&S FPL1 Noise Figure measurements application. The name of each ENR table contains the serial number of the SNS. For smart noise sources, use the lemosa female connector on the front panel. To con- nect a noise source with a BNC connector, use the noise source control female con- nector on the rear panel (requires the R&S R&S FPL1000-B28V option).
Page 39: Analyzing Several Traces - Trace Mode
® Measurement basics R&S FPL1-K30 Analyzing several traces - trace mode depending on the current frequency of the sweep point. The variable RBW and sweep times are defined in the frequency table (see Chapter 5.2.3, "Using a frequency table", on page 48). The defined RBW and sweep times are also included in a table export. In the channel bar, the bandwidth and sweep time range of the variable values is indi- cated.
Page 40: Using Markers
® Measurement basics R&S FPL1-K30 Using markers 4.9 Using markers Markers are used to mark points on traces, to read out the results of a particular mea- surement point or compare results of different traces. The noise application provides four markers. When you activate a marker, the application automatically positions it on the first mea- surement point (left border of the diagram) of trace 1, regardless of how many traces are active.
Page 41 ® Measurement basics R&S FPL1-K30 Using markers "View" trace mode, e.g. to compare measurement results. Note that at least one active marker has to be a normal marker. The application shows the results at the marker position directly in the diagram area (up to two markers) or in the marker table (if you use more than two markers).
Page 42: Configuration
® Configuration R&S FPL1-K30 Configuration overview 5 Configuration "Noise figure" measurements require a special application on the R&S FPL1000, which you activate using [MODE]. The Noise Source Control connector on the R&S FPL1000 is also a prerequisite for the R&S FPL1 Noise Figure measurements application. Without this connector, no mea- surement can be performed.
Page 43 ® Configuration R&S FPL1-K30 Configuration overview In addition to the main measurement settings, the "Overview" provides quick access to the main settings dialog boxes. The individual configuration steps are displayed in the order of the data flow. Thus, you can easily configure an entire measurement channel from input over processing to output and analysis by stepping through the dialog boxes as indicated in the "Overview".
