Page 27: Swept Measurements
® Measurement basics R&S FSW-K30 Tuning modes 4.1.1 Swept measurements The sweep tuning mode performs measurements on a set of discrete frequencies based on the frequency parameters. Each measurement analyzes the noise character- istics of the corresponding frequency or measurement point. For swept measurements, the application automatically determines the measurement frequencies and combines them in a frequency list.
Page 28: Measurement Modes
® Measurement basics R&S FSW-K30 Measurement modes Single frequency measurements are a way to facilitate manual adjustments for "noise figure" measurements. They also allow you to get an idea about how the "noise figure" at a particular frequency change over time. Note that sweep lists or frequency tables are not considered in this measurement mode.
Page 29 ® Measurement basics R&S FSW-K30 Measurement modes Recommended order of measurements Note that it is recommended that you begin with the hot power measurement. Furthermore, calibration always begins with the hot power measurement. In case the hot power has to be measured first, the cold power measurement is unavailable: When the first measurement is done, you can change the test setup by connecting the other resistor.

Page 31: External Generator Control
® Measurement basics R&S FSW-K30 External generator control 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 32 ® Measurement basics R&S FSW-K30 External generator control The typical measurement setup for such measurements includes the FSW equipped with the optional R&S FSW Noise measurements application, a signal generator and the DUT. The signal generator is controlled either via the LAN connection or the GPIB interface.
Page 33: Image Frequency Rejection
® Measurement basics R&S FSW-K30 Image frequency rejection Message Description "Ext. Generator Command Error!" Missing or wrong command in the generator setup file. "Ext. Generator Visa Error!!" Error with Visa driver provided with installation (very unlikely). Risk of damage to the instrument To allow for highest sensitivity during the measurement, the R&S FSW Noise measure- ments application automatically sets the input attenuation to 0 dB.
Page 34 ® Measurement basics R&S FSW-K30 Image frequency rejection = frequency of the local oscillator ± f = intermediate frequency = f = lower sideband = f = upper sideband = f image If image rejection is on, the results have a 3 dB error. That means "noise figure" results are 3 dB lower than they should be.
Page 35 ® Measurement basics R&S FSW-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 36: Calibration (2Nd Stage Correction)
® Measurement basics R&S FSW-K30 Calibration (2nd stage correction) 4.6 Calibration (2nd stage correction) The calibration procedure of the application measures the inherent noise of the FSW you are using. Performing calibration is therefore recommended, as it increases the accuracy of measurement results. The results get more accurate because the applica- tion takes the inherent noise of the analyzer into account while it calculates the results.
Page 37 ® Measurement basics R&S FSW-K30 Calibration (2nd stage correction) Note that useful interpolation is possible only if essential calibration parameters (e.g. impedance or attenuation) change only slightly. This is the case if the distance between the original calibration points is sufficiently small. If the span increases compared to the span during calibration, a new calibration is necessary.
Page 38 ® Measurement basics R&S FSW-K30 Calibration (2nd stage correction) Calibration Save If the user has performed a valid calibration on the instrument, the calibration results can be saved by using "Calibration Save" in the "Export" dialog. This provides the pos- sibility to use once stored calibration results at a later point.
Page 39: Using Smart Noise Sources
® Measurement basics R&S FSW-K30 Separating signals by selecting an appropriate resolution bandwidth Remote command: on page 155 [SENSe:]CORRection:RECall 4.7 Using smart noise sources A smart noise source (SNS) provides its own ENR and uncertainty tables and a tem- perature value from an internal measurement. Thus, accuracy is improved and less configuration efforts are required.
Page 40: Analyzing Several Traces - Trace Mode
® Measurement basics R&S FSW-K30 Analyzing several traces - trace mode If the RBW is too large, signal parts that are very far away (e.g. from a different signal) are considered in the measurement and distort the results. The displayed noise increa- ses.
Page 41: Using Markers
® Measurement basics R&S FSW-K30 Using markers If you change the scaling of the y-axis, the FSW automatically adapts the trace data to the changed display range. Thus, you can perform an amplitude zoom after the mea- surement to show details of the trace. 4.10 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.

Page 235: Using The Status Register
® Remote control commands for noise figure measurements R&S FSW-K30 Using the status register Manual operation: "Search Next Minimum" on page 106 7.20 Using the status register The status reporting system stores information about the current state of the FSW. This includes, for example, information about errors during operation or information about limit checks.

Page 236 ® Remote control commands for noise figure measurements R&S FSW-K30 Using the status register Figure 7-2: Status registers for noise figure measurements The FSW structures the information hierarchically, with the Status Byte register (STB) and the Service Request Enable mask register (SRE) being on the highest level. The STB gets its information from the standard Event Status Register (ESR) and the Event Status Enable mask register (ESE).

Page 237: Status:operation Register
® Remote control commands for noise figure measurements R&S FSW-K30 Using the status register els of the status register and are defined by SCPI. They contain information about the state of the instrument. For a more comprehensive description of the status registers not mentioned here, and status register functionality in general, see the manual of the base unit.

® Remote control commands for noise figure measurements R&S FSW-K30 Using the status register 7.20.1.3 STATus:QUEStionable:LIMit register The STATus:QUEStionable:LIMit register contains information about limit lines and the results of a limit checks. The number of LIMit registers depends on the number of measurement windows avail- able in any application.

® Remote control commands for noise figure measurements R&S FSW-K30 Deprecated remote commands for noise figure measurements Setting a bit causes a 0 to 1 transition in the corresponding bit of the associated regis- ter. The transition also writes a 1 into the associated bit of the corresponding EVENt register.
