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.

  • Page 27 3 – Operating Instructions 3.1 Introduction The PMM ER9000 EMI Receiver can be operated as a stand-alone receiver or remotely driven by a PC through an USB connection. The system is provided with a specifically developed software called PMM Emission Suite, which installer utility is stored on the Software Media shipped together with the instrument.
  • Page 28 The Sweep Mode is the most common way to perform measurements in the EMI environment. The Sweep mode is conceived to operate the PMM ER9000 as a powerful 3.2.1.1 Scan Table scanning EMI receiver. To enter in this mode it is enough to touch the Sweep software key on the main screen, and immediately the scan window pops up and allows the operator to set the parameters for the scan.
  • Page 29 3.2.1.3 Limit Each emission standard has one or more limits the User shall comply with. The PMM ER9000 receiver has the possibility to load and activate one limit with a simple touch of a button. The preloaded standard limits refer to the most popular EMC emission standards: CISPR22, CISPR14 and CISPR11.

  • Page 34 The Input button opens a submenu, which is dedicated to the setting of the input attenuator, and to switch on-off the built-in preamplifier. The PMM ER9000 receiver takes automatically into account the settings of all the Input parameters and always displays the correct value of the level. The User does not need to calculate any correction to the readings.
  • Page 35 Use 0 dB attenuation only if you are very sure that your input signal is less than 1 Vpp (or 120 dBµV). Before to apply an unknown signal to PMM ER9000 receiver, use an oscilloscope or a wide band RF voltmeter to measure it. In any case set Min.
  • Page 36 PMM ER9000 has been designed to allow the use of many kinds of detectors. 3.2.3.1 Detectors CISPR Standard has introduced the application of two detectors that are derived from the Root Mean Squared and from the Average ones.

  • Page 38 The Input button opens a submenu which is dedicated to the setting of the input attenuator and to switch on-off the built-in preamplifier. The PMM ER9000 receiver takes automatically into account the settings of all the Input parameters and always displays the correct value of the level. The User is not required to make any correction to the readings.
  • Page 39 Use 0 dB attenuation only if you are very sure that your input signal is less than 1 V (or 120 dBµV). Before to apply an unknown signal to PMM ER9000 receiver, use an oscilloscope or a wide band RF voltmeter to measure it. In any case set Min.
  • Page 40 The Preselector is composed by a group of filters automatically selected by the PMM ER9000 while it is sweeping or anyway measuring. The aim of the preselector is to reduce the amount of out-of-band energy entering in the receiver, thus helping a lot in reducing intermodulation problems and similar undesired behaviors.
  • Page 41 PMM ER9000 integrates also a CISPR 16 Band-A and Band-B pulse generator for special testing. It consists of an instrument capable of generating time- domain rectangular pulses, which produce an almost flat response over frequency.

  • Page 43 In this case, the PMM ER9000 sees a high input signal and therefore tries to set the proper attenuation automatically, increasing the value or the input attenuators.
  • Page 44 3.2.4 Smart The Smart Detector is a special function implemented in the PMM ER9000 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 45 When a non-CISPR filter is selected, the Quasi Peak, C-RMS and C-AVG detectors are disabled. Be sure not to overload PMM ER9000: the input signal should not exceed the maximum level indicated in the main specifications in chapter 1. The measuring time must be properly set in the Hold Time window to allow the desired detectors to operate as intended.

Typically, the user should first send the PMM ER9000 all the setting commands to insure the receiver is correctly set on the wanted parameters and then read the reply.

  • Page 97 The main window will be the IDLE function, which allows a preliminary, free running evaluation, at the selected frequency and level. To increase test productivity the PMM ER9000 has some very unique features: it allows skipping as many as 2 steps, as it may predict how many clicks would overcome the Lq limit and may also advice the User if the next step would fail.
  • Page 98 To better understand the click measurement process – automatically made by PMM ER9000 - it could be useful also to know few more definitions: • switching operation: one opening or closing of a switch or contact;...
  • Page 99 Thanks to its digital architecture, PMM ER9000 can easily record and store all the relevant parameters, keeping trace of all the events occurring during the test and allowing the User to post-process all these data; PMM ER9000 will also notify immediately the test results to the User.
  • Page 100 – after that the analyzer will immediately continue measuring the number of clicks exceeding the upper quartile limit L Simply select Start: the PMM ER9000 will automatically take care of all the necessary steps, reporting at the end of the test all the relevant results.
  • Page 101 Before to apply an unknown signal to PMM ER9000 receiver, use an oscilloscope or a wide band RF voltmeter to measure it.
  • Page 102 After a Click test the PMM ER9000 reports all the relevant data. 8.6 Report Due to the complexity of the test and to the various conditions that may happen during the measurement, several reports may be issued. In case a test failed condition is recorded during the determination of the 8.6.1 Fail during...
  • Page 103 The Click test may be rather long, as the observation time and EUT cycle can take as long as 120 minutes. In order to save time and increase productivity, the PMM ER9000 can stop the test as soon as a fail condition is achieved.
  • Page 104 As required by the relevant standards, the discontinuous measurement 8.9 Test Set up (Click) test set up shall be the same adopted for continuous disturbances, therefore, usually, a LISN is used to sample the RF signal to be measured. In case the internal LISN is to be used, it is the one contained in the PMM CA0010 Click Analyzer.
