SERIAL NUMBER OF THE INSTRUMENT
You can find the Serial Number on the rear panel of the instrument.
Serial Number is in the form: 0000X00000.
The first four digits and the letter are the Serial Number prefix, the last five digits are
the Serial Number suffix. The prefix is the same for identical instruments, it changes
only when a configuration change is made to the instrument.
The suffix is different for each instrument.

The RMS-Average detector is a special function, defined by the CISPR 3.3.1 RMS-AVG standard, implemented in the PMM ER8000 receiver.
  • Page 32 3.3.3 Smart The Smart Detector is a special function implemented in the PMM ER8000 Detector receiver with the purpose of reducing the test time and increasing the productivity of the lab. This function works only in the C, D and E bands when at least one limit is loaded, therefore remember to enable a limit to run the Smart detector function.
  • Page 33 With the Peak, RMS and AVG detectors the smallest settable measurement time depends on the RBW. If several detectors are used contemporarily the Hold Time should be set to meet the requirement of the slowest one, so that the results of the measurement are correct for all them.
