Note: Do not confuse the "Preset Channel" button with the [Preset] key, which restores the entire instrument to its default values and thus closes all channels on the R&S ESW (except for the default channel)!

  • Page 22 ® Configuration R&S ESW-K58 Data input and output In addition to simply changing the volume, you can also define a maximum volume level. The maximum volume level limits the audio output to a certain level. The volume control knob and slider will not go further than this level.

  • Page 24 ® Configuration R&S ESW-K58 Amplitude The reference level can also be used to scale power diagrams; the reference level is then used for the calculation of the maximum on the y-axis. Since the hardware of the R&S ESW is adapted according to this value, it is recom- mended that you set the reference level close above the expected maximum signal level.
  • Page 25 ® Configuration R&S ESW-K58 Amplitude Remote command: Global: on page 76 INPut<ip>:ATTenuation[:VALue] Attenuation mode: on page 75 INPut<ip>:ATTenuation:AUTO 10 dB Minimum Attenuation Turns the availability of attenuation levels of less than 10 dB on and off. When you turn on this feature, the attenuation is always at least 10 dB. This minimum attenuation protects the input mixer and avoids accidental setting of 0 dB, especially if you measure EUTs with high RFI voltage.
  • Page 26 ® Configuration R&S ESW-K58 Amplitude Risk of damage to the input mixer Do not overload the input mixer. Overloading the input mixer can damage it. The following topics contain advice on how to avoid an overload of the input mixer. Read them carefully before applying a signal.
  • Page 27 ® Configuration R&S ESW-K58 Amplitude ● High attenuation increases inherent noise (i.e. the noise floor) and thus decreases measurement sensitivity: if you increase attenuation by 10 dB, the sensitivity is reduced by 10 dB (in other words: the displayed noise increases by 10 dB) Depending on the required test setup, a compromise must be found between a high sensitivity, low intermodulation and input mixer protection.
  • Page 28 ® Configuration R&S ESW-K58 Amplitude ● The preamplifier is located after the preselection filters, reducing the risk of over- loading the input mixer by strong out-of-band signals. ● The optional low noise amplifier is located in front of the preselection filters which increases the measurement sensitivity.

    ® Remote commands for Multi CISPR APD measurements R&S ESW-K58 Analysis For a single measurement, the R&S ESW stops measuring when it has reached the end frequency. When you start a continuous measurement, it stops only if you abort it deliberately.
  • Page 90 ® Remote commands for Multi CISPR APD measurements R&S ESW-K58 Analysis FORMat:DEXPort:TRACes <Selection> This command selects the data to be included in a data export file (see MMEMory: on page 91). STORe<n>:TRACe Parameters: <Selection> SINGle | ALL SINGle Only a single trace is selected for export, namely the one speci- fied by the command.
