  • Firmware Rollback

    I want to update my firmware. Can I also roll back the firmware to my old version before firmware update?When the analyzer firmware is updated, the analyzer will boot and operate exactly as before – in some cases even better. But if you want to return to the old version, you can restore the old analyzer firmware by pressing SETUP =>NEXT => FIRMWARE RESTORE.After you have pressed FIRMWARE RESTORE, the

  • Sending a Remote Control Ccommand Internally

    I need to send a remote control command to the device, but I do not have a PC available to control the device.Can I do this internally with the device itself?Yes, Go to the device's Windows function Open the Windows Explorer Open the C:\Program Files\Rohde&Schwarz\Network Analyzer\Bin folder Execute the iecwin32.exe program Choose the RSIB interface and push the Connect Now button Now you can write

  • How to check the internal Calibration Source?

    During calibration I got the error message 'CAL GEN signal low'.How can I check the internal calibration source?You can switch the RF path to the internal calibration source in the SETUP - SERVICE menu(menu for the FSL: SETUP - MORE - SERVICE).The calibration source should be a signal of 128 MHz and -30 dBm (for the FSL 65.8 MHz and -20 dBm).

  • Measure Low Frequency Signals with DC Offset

    I want to measure noise at a very low frequency (20 Hz to 100 kHz).The signal has a DC offset, but at the input of the analyzer only 0 V DC are allowed with DC coupling.The DC blocks starts at 7 kHz.How can I measure these signals without destroying my device?At these frequencies, an external block capacitor can be used. But a rather high capacity is required to ensure the low cut-off frequency, which

  • UNCAL Message on the Screen

    I get a red UNCAL message on the screen.Full internal calibration was already performed. The sweep time is set to AUTO.What is wrong?If you select a wrong setting regarding the 'RF INPUT AC/DC' for the selected frequency range, you will get an 'UNCAL' message.

  • Remote command „CALC:UNIT:POW DBUV” is not accepted

    We use the receiver mode. After sending the command “CALC:UNIT:POW DBUV” we get the error “-200,"Execution error; Function not available” back. That command is mentioned in the manual and the “unit” dBuV” should be available. What is wrong?You are right - in receiver mode it must be possible to use dBuV. In fact, that is the default setting after a preset.Please check if there is any other transducer

  • Why is it helpful to do Data Reduction?

    I want to do an EMI scan using a quasi-peak. Why is it recommended to first do apre-scan with data reduction and a peak list?EMI measurements may take a long time because the time constants prescribed bythe standard for quasi-peak detectors lead to long measurement times for thewhole scan. In addition, the standards stipulate procedures for finding localEMI maxima, e.g. switching the LISN or varying

  • Add Limit Line to existing EMC32 Test to create a new list of critical frequencies

    I have saved an EMI Test and would like to add a new Limit Line to the existing Test, optionally I would like to create a new list of critical frequencies, based on the new limit line. How can I do this with EMC32?Yes, you can do this. You can load the Test and you can add a new limit to the exisitig graphic. It is also possible to run a new EMI Evaluation to get new critical frequencies. Attached

  • ESU/FSQ with Windows XP has "Registry File Failure"

    I got an error message when starting/booting my ESU / FSQ with Windows XP (registry file failure):It is not possible to enter the ESU / FSQ application. (IMGn1039.jpg) shows the error message.stop: c0000218 (Registry File Failure):the registry cannot load the hive(file):\systemroot\system32\config\SYSTEMor its log or alternate.It is corrupt, absent, or not writeableThis seems to be a small head crash

  • Time Domain Scan without Autoranging

    When Time Domain Scan is ON, it is not possible to use autoranging. Is there anything I should take into consideration without autoranging?In general, there is no 100% guarantee for an overload-free measurement even if Autoranging is switched on. For example, there is no overload indication for preamplifiers in front of the preselector (e.g. external amplifier or ESU-B24).Even if Autoranging is ON,

  • FSx doesn't recognize active probe RT-ZS30

    We have an issue with our FSx and the RT-ZS30 probe: the FSx does not automatically recognize the probeCould you please help us to solve this blocking issue.You can work with the RT-ZS30 connected to the FSx as follows:+ The RT-ZA9 provides an interface between the probe's BNC socket and an N socket and also supplies the probe with the necessary supply voltages via the USB connection. Simply connect

  • How can I Update my Analyzer via LAN?

    How can I update my analyzer with embedded WIN XP via LAN?- Open a remote desktop session to the analyzer on your PC- Close the analyzer function on the PC with ALT + F4- Open Start=> Settings => Control Panel => Security Center => Windows Firewall => Exceptions- Enable 'File and Printer Sharing'- Start the Windows Explorer, go to Tools, select 'Map network drive..' and enter '\\<TCP/IP-Address of

  • How can I Switch from Remote to Local State via Remote Control?

    How can I switch from remote to local state via remote control?Using a GPIB connection, you can send a Go To Local (GTL) command.If you use VISA, the command is viGpibControlREN and you have to send the VI_GPIB_REN_DEASSERT_GTLmode.You can also use this solution when you perform programming with drivers.If you use the GPIB driver, you need the GTL command.

  • Self Alignment via remote control via TCP/IP => 'CAL?

    I want to make the Self Alignment via remote control with the command 'CAL?'.Because this takes sometimes a very long time how can I detect the end.In the manual is mentioned to use a SRQ, but this does not work when I use a TCP/IP connectionYes, the SRQ line is a hardware line with the IEEE bus and this does not work with normal TCP/IP. So we cannot use it.Because the calibration command is a query

  • Correct Step Size for a Stepped EMI Scan?

    Why is it important to use the correct step size for a stepped EMI scan?In the case of EMI measurements, the frequency range is analyzed in frequency steps. An important parameter is the IF bandwidth specified by the standards. The step size for a scan depends on the IF range.The step size is important for the following reasons:- If the step size is very large, narrowband interferer cannot be detected

  • Remote Desktop: How can I see all Analyzer Buttons on the PC Screen?

    I have connected my PC to the analyzer via LAN. The firewall settings are made, I have a remote desktop connection, but I cannot see all buttons of the analyzer on my PC.I even shut down the analyzer function and restarted the analyzer function on the analyzer, but this did not help either.Please do not restart the analyzer function on the analyzer. You must restart it from the PC.Perform the following
