EMI Test Receiver ESIB7, ESIB26 and ESIB40
Dear Customer,
your EMI test receiver is equipped with a new firmware version. The new firmware offers a number of
extensions and improvements which are not yet described in the operating manual. They are explained
on the following pages. The new functions concern:
• Setting the input attenuation to 0 dB via roll-key no longer possible in Analyzer mode
• Limit lines with additional unit dBpT, editing feature extended
• Extended functionality for option External Mixer Output (FSE-B21)
• Extension of the detector selection by the CISPR Average detector.
• Extension of the adjacent channel power measurement.
• Selection of trace averaging method
• Additional IEEE/IEC-bus commands
Correction of Operating Manual, Section "Windows-NT Software Installation"
The stated path for starting the reinstallation is only valid for software pack 3 ("C:\SP3\I386\update").
To start the reinstallation of software pack 5 path "C:\SP5\I386\update\update" has to be entered into
the command line.
Input Attenuation 0 dB can no longer be set via Roll-key in Analyzer mode
In order to prevent the input attenuation from being inadvertently switched off, value 0 dB can only be
set via manual input. The input attenuation can only be reduced up to 10 dB via roll-key or UP/DOWN
keys. In Receiver mode, the availability of the 0 db setting is already controlled with the 0 DB MIN
softkey.
Limit lines with additional unit dBpT, editing feature extended
dBpT can be set as additional unit for limit lines.
In firmware versions used so far, a physical unit once set could not be changed. In the new firmware
version this is now possible. The entered reference values remain unchanged
External Mixer option FSE-B21 extended
The permissible setting range of parameter HARMONIC NUMBER under BAND LOCK OFF was
increased from 40 to 62.
