  • How to Create a User-Defined PRESET

    How to create a user-defined PRESETTo create your own PRESET, please proceed as follows:- Push the PRESET button.- Make the settings you want for your own PRESET.- Store the setup under a specific name (for example "MYPRESET")on the FSIQx, FSEx, ZVx and ESIBx:- Go to the "RECALL" menu (on the ZVx in the right side menu) and select the setup "MYPRESET" under"AUTO RECALL"on the FSQx, FSUx, FSPx, ESPIx

  • Which Receiving Antenna is the right one?

    How can I decide which receiving antenna is the right one for applications with my test receiver?Emission testing requires a low antenna factor because the passive structure of broadband antennas adds a certain correction value to the receiver's noise floor and because the antenna factor influences the sensitivity. The lowest antenna factor is obtained by using antenna elements close to resonance.

  • 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

  • Noise Measurement with ESIB?

    Is it possible to use the Noise Measurement Software FS-K3 with the EMI Receiver ESIB?Yes, Noise Measurement Software FS-K3 operates in the spectrumanalyzer mode of the EMI Receiver ESIB.

  • User Port Cable for ESH3-Z5

    s it possible to use the same USER PORT cable forEMI Test ReceiverESxI andTwo-Line V-NetworkESH3-Z5as forEMI Test ReceiverESI andTwo-Line V-NetworkESH3-Z5?The cables EZ-4 and EZ-6 for ESxI can also be used for ESIB without any changes.

  • What is the Structure of FSE/FSIQ Trace Data on the GPIB?

    How to convert the binary trace result from the GPIB using the command 'TRAC? TRACE1' ?The default format after *RST is the ASCII format. That means you will get 500ASCII values, which are separated by commas, in a single string (approx . 6 Kbyte)that is terminated by a line feed (0A hex).To use the floating point format you have to send the command "FORMAT REAL,32"beforehand.The FSE will answer the

  • How to read the Scan Data from 30 MHz to 1 GHz?

    The following program defines a scan from 30 MHz to 1 GHz, starts it and writes all scan data in a file.10 IEC TERM 1020 IEC TIME 500025 REM The scan data will be stored in the file 'DATA.DAT'30 OPENO# 1,"DATA.DAT"35 REM The scan is defined in lines 40 to 20040 IEC OUT 21,"*RST;*CLS;*OPC"50 IEC OUT 21,"INSTRUMENT RECEIVER"60 IEC OUT 21,"SCAN:RANGES 1"70 IEC OUT 21,"FREQUENCY:START 30MHZ"80 IEC OUT

  • 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

  • Upload and Download of Transducer Factors

    Is there a tool for downloading transducer factors to my test receiver?Yes, there is a tool. Please run the attached Excel file. It contains a table forfrequencies and factors and a selection of different units. You can alsoselect linear and logarithmic interpolation. You can download a transducer factorvia the GPIB or LAN interface (if your test receiver is also equippedwith a LAN interface). Name

  • When do I need a Pulse Limiter?

    When do I need a pulse limiter?The input attenuator, preamplifier, preselection filter or input mixer can bedestroyed if you perform measurements on devices with very high pulsespectral density/pulse energy.For higher voltages as occur e.g. in the case of measurements with absorbing clamps orLISNs, we recommend using the external Pulse Limiter ESH3-Z2 with everytest receiver. This 10 dB attenuator
