11 1.4 Known Issues The following table lists the known issues and indicates since which version the issue could be observed: since V4.20 The measurement zoom button in the toolbar is always available although some options are not intended to support this feature and the button should be unavailable. V4.30 License key installation over R&S License Manager webpage often shows a red error message in the last line. Nevertheless, the license key has been properly installed on the device, which can be seen after the reboot. V4.20 Touch gestures with a y-scaling in linear percent or linear with unit do not always work. V4.20 MSRA mode in I/Q Analyzer or K7: Dragging X-axis which are reflecting a time unit has no effect. V1.81 If the additional software R&S DigIConf should be installed directly on the FSW, please use the version V Build220 SP1 or newer (Beta available upon request) older version may have data transfer problems or show white screens. The R&S DigIConf software might prevent windows to shut down occasionally. If this happens, please select "Force shut down" and confirm. V2.80 FSW-B512R: Attenuation occurs further than 240MHz away from the center frequency in replay zoom. V2.40 FSW-B512R: For some resolution bandwidths, a single sweep causes artifacts in the spectrum that are caused by the instrument itself. V2.40 FSW-B160R/B512R: Kaiser window not supported. If selected a Blackmann Harris window is applied. V1.90 FSW-B160R: Auto Adjust functions are not available in MSRT mode. V1.80 FSW-B160R: No full support of trigger outputs. "Device Triggered" mode for "Frequency Mask Trigger" is available for trigger output 3 only. V2.20 FSW-B2000: In some situation after recalling a file with active B2000 configuration the connection to the R&S RTO is not established. Workaround: After the recall switching the B2000 state off and on again should solve the problem. V3.20 FSW-K6 with FSW-B512/B1200/B2001: First sweep with gauss filter at 200 MHz may stop. Change the BW and back to 200MHz will resume operation. V2.90 FSW-K6: When using B2000 or B5000 with segmented capture mode, the timestamps and PRI values may not be correctly shown V2.80 FSW-K6: Segmented capture with FSW-B512R can produce incorrect segment lengths. V2.70 FSW-K6 with FSW-B512/B1200/B2001: When using the external or IF power trigger then the segmented capture timing may become inaccurate for short segment lengths (under 400ns) or small amount of pre-trigger samples (under 100ns). V2.60 FSW-K6/K60: When using the IF power with bandwidths 1.2 GHz (B1200) or 2 GHz (B2001) then the segmented capture timing may become inaccurate for short segment lengths (under 400ns) or small amount of pre-trigger samples (under 100ns). V2.40 FSW-K6: The user can set a larger amount of segment data than is actually possible with certain RTO configurations (using FSW-B2000). In this case, the lower number of available segments will be analyzed and a warning will appear in the status bar. V2.20 FSW-K6: The view trace behaves like a clear write trace. V1.51 FSW-K6: After recalling a Pulse channel which was saved after a RUN SINGLE operation, the RUN SINGLE button is lit but no measurement is running. V1.41 FSW-K6: After aborting a measurement via SCPI (:ABORt) the status bar still shows "Measuring...". V1.41 FSW-K6: The following commands are not available: [SENSe:]FREQuency:CENTer:STEP [SENSe:]FREQuency:CENTer:STEP V1.60 FSW-K10: Cumulating of Modulation Spectrum limits of carriers of a multicarrier BTS not supported for frequency offsets < 1.8 MHz of the outmost carrier. Release Notes

12 since V4.30 FSW-K18: Due to an unintended correction mechanism, Baseband I Input Voltage and Baseband Q Input Voltage influence each other if there is a frequency error or a sample rate error. To avoid this, the external references of R&S SMW and need to be coupled. V4.30 FSW-K18: On instruments equipped with analog baseband inputs, the displayed capture time is sometimes not updated when reducing the capture length below a certain number. V3.20 FSW-K18: The crest factor of signals created by the Generate Own Reference Signal - functionality lies in a range between about 9.5 db and 10.5 db even if higher or lower values were selected in the dialog. Since version 4.30 it is no longer possible to select values lower than 9.5 db or higher than 10.5 db. V2.90 FSW-K18: Markers are not available for Parameter Sweep measurements. V2.70 FSW-K18: Pressing softkey "Update DPD Tables on Generator" directly after starting the application may lead to a lock up of the instrument. V2.60 FSW-K60: Adding a marker to the spectrum resets selected frame in the spectrogram. V2.70 FSW-K70: CALCulate<n>:MSRA:WINDow<n>:IVAL? and the displayed analysis range in the MSRA only works reliably for capture lengths <= Samples V2.70 FSW-K70: CALCulate<n>:MSRA:WINDow<n>:IVAL? and the displayed analysis range in the MSRA only works reliably for capture lengths <= Samples V2.60 FSW-K70: In remote mode, if the capture buffer length exceeds symbols and if the command SENSE:DDEMOD:SEARCH:MBURST:CALC is sent right after the finished measurement, occasionally the trace in the Mag(Capture Buffer) display is not visible. Workaround: Send refresh command (INIT:REFM) and resend SENSE:DDEMOD:SEARCH:MBURST:CALC command. V2.60 FSW-K91N: For specific n antenna 2, 3,.. signals with cyclic shift delay the EVM might drop by approx. 1 db. V2.60 FSW-K91AX HE Trigger-based PPDU analysis: In some cases the auto bandwidth detection might fail. A work around it to set the bandwidth of the signal to be measured manually. FSW-K91AX HE Trigger-based PPDU analysis: For 40MHz signals with short GI/HE-LTF size, the auto detection might fail. A work around it to set the GI/HE-LTF size of the signal to be measured manually. FSW-K91AX HE MU PPDU: Only manual PPDU Configuration is supported FSW-K91AX Ext Range SU PPDU: Only RU242 size is supported. No MIMO is supported. V2.50 FSW-K91/192/K193: In some cases (using FSW-B512) auto level might not produce optimal results. Manual adjustments of the amplitude settings may be required in these cases. V2.00 FSW-K91: Please use not more than three FSW-K91 channels - at maximum capture time - to ensure that the memory of the application is not exceeded. V1.90 FSW-K91: When measuring MIMO and recalling a save set containing the same IPaddresses of the connected devices the measurement will stop working. Please delete the shutdown file 'C:\R_S\Instr\results\Shutdown.dfl' and power cycle the FSW on the rear main switch. V1.42 FSW-K91, -K91N, -K91AC: In case the instrument is waiting for a trigger this message is not displayed in the status bar. V2.90 FSW-K95: When loading an I/Q file, an incorrect warning is displayed occasionally. The warning states that the sample rate of the file was different from the sample rate of the application even though the sample rate of the file is equal to the application sample rate.

LTSB stands for Long Term Servicing Branch which means a long support period of Windows patches.) 1.6 Exchanging Solid State Disks Between Different Types of CPU Boards For the FSW spectrum analyzer, different CPU boards are in use: IPC10 with order no and IPC11 with order no If the solid state disk is exchanged between FSWs with different types of CPU boards, the screen resolution is only 800x600 and a "Drive Access Error" is displayed by the firmware. Switch off the device and change back to the solid state drive which fits to the CPU board. The device will boot as usual. 1.7 Missing smartcard Message For FSW spectrum analyzers produced July 2017 or later, the message Missing smartcard or smartcard not initialized may appear after starting the device. This only happens if a firmware below V2.60 is used. Either because a downgrade to a version below V2.60 had been performed, or the solid state drive was exchanged with a version below V2.60.
