    UNCAL Message on the ScreenQuestionI get a red UNCAL message on the screen.Full internal calibration was already performed. The sweep time is set to AUTO.What is wrong?AnswerIf you select a wrong setting regarding the 'RF INPUT AC/DC' for the selected frequency range, you will get an 'UNCAL' message.The input of the ESU is divided into a DC-coupled and an AC-coupled frequency range. The ranges are

  • Time Domain Scan without Autoranging

    Time Domain Scan without AutorangingQuestionWhen Time Domain Scan is ON, it is not possible to use autoranging. Is there anything I should take into consideration without autoranging?AnswerIn 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.

  • How to set Limit Lines with Frequency Gaps?

    How to set Limit Lines with Frequency Gaps?QuestionHow can I set limit lines that contain frequency gaps?Up to now, you had to enter a pseudo limit of 200 dB, but that doesn't look nice on the screen.AnswerPlease proceed as follows:Select a limit line and split it up into two parts: one before and one after the frequency gap. Create each line with the "new limit line" softkey (after pressing the "

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

    Self Alignment via remote control via TCP/IP => 'CAL?QuestionI 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 connectionAnswerYes, the SRQ line is a hardware line with the IEEE bus and this does not work with normal

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

    How can I Switch from Remote to Local State via Remote Control?QuestionHow can I switch from remote to local state via remote control?AnswerUsing 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

  • Correct Step Size for a Stepped EMI Scan?

    Correct Step Size for a Stepped EMI Scan?QuestionWhy is it important to use the correct step size for a stepped EMI scan?AnswerIn 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

  • Measure Low Frequency Signals with DC Offset

    Measure Low Frequency Signals with DC OffsetQuestionI 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?AnswerAt these frequencies, an external block capacitor can be used. But a rather high
