The Voltage Passive probes are ancillaries specifically designed for the measurement of conducted disturbances, either to EUT of line current exceeding the LISN capability and to the disturbances of EUT’s load and control terminals, as required by various generic and product standards: IEC/EN, CISPR etc.
Connected to the RF input of EMI receivers and spectrum analyzers, their primary functions are of: blocking the AC/DC voltages of EUT’s power line, providing a standardized impedance to the disturbance voltages and attenuating the same to preventing the receiver input to saturate or being damaged.
Operating the voltage probes requires the user to apply the necessary safety measures in relation with the AC or DC line voltages.
SBRF4 RF Switching Box
PMM’s SBRF4 is a versatile RF switching box particularly suitable for scanning in automatic mode, when driven by PMM’s EMI receivers, multi-channel ancillaries as the LLA - Large Loop Antenna - and the conducted immunity set-ups with up to four single-line AMN (LISN).
The internal, selectable 50 Ohm terminations comply with the requirements of those devices that must not remain unterminated on the unselected channels.
The selectable 150 kHz high-pass filter is very useful to cut off unwanted noise from the A-band (9 - 150 kHz) when performing conducted disturbances tests in the B-band (150 kHz - 30 MHz).
The manual mode also allows for using the SBRF4 RF switch in conjunction with any receiver or spectrum analyzer other than PMM’s ones.

New product: PMM Cond-IS RF Conducted Immunity System
RF Conducted Immunity System
NARDA Italy has renewed its already well known PMM 6000S/10 RF Immunity System with components and test management software to follow and even overcome latest requirements from the Standard IEC/EN 61000-4-6 and IEC/EN 61000-4-3.
Continuing with the philosophy of a "Modular Approach", which still provides several advantages for actual use and future upgrades of the system when compared to "compact" solutions, main innovations are represented by a completely redesigned software (PIMS), introduction of the new RF Generators PMM 3010 or 3030 and the True RMS Power Meter PMM 6630, all of them remotely driven through USB Ports by any PC.
PMM 6630 power meter can be operated up to 3 GHz, so representing an ideal companion for Radiated Immunity applications as well, in particular when matched to the same frequency range provided by the RF Generator model PMM 3030.
The new "PMM Immunity Suite" (PIMS) software, accurately designed in terms of functions and user friendly approach, can manage the whole range of PMM components during both Test and Calibration processes, introducing the possibility of looking at the various monitoring tracks from generator, power meters and field sensors. The software is user friendly and provides a really ergonomic configuration which comfortably drives the operator through the various steps, from definition and selection of HW components to settings of required parameters and finally starting the test with "just one button". Program window has been designed for omni-comprehensive overview of each specific test being performed, so that operator can easily control all details with a quick glance. A graphical scheme of the test set-up clearly reminds about proper physical connections between components, which could slightly differ between Tests and Devices' Calibrations.
In case of Radiated Immunity Tests according to IEC/EN 61000-4-3 in Anechoic Chambers or TEM/GTEM Cells, PIMS does also include calibration of radiated field up to 16 points in the grid of Field Uniformity assurance, providing "Amplifier Saturation Check" routine for proper amplifier/antenna matching verification at 80% AM Modulation increased power.
PMM L1-150M is a single-path LISN (Line Impedance Stabilization Network) designed to
be easily used for conducted disturbances measurements according to different
standards for Automotive and ISM (Industrial, Scientific, Medical) applications:
CISPR 25 / ISO 11452-4
Selecting the standard is as fast as the turn of a rotary switch located on the rear panel.
It can be used in conjunction with any EMI Receiver or Spectrum Analyzer.
NARDA-PMM innovative concept in EMC Testing has generated a new EMC/EMI Receiver with a revolutionary approach to the most felt requirements by medium and small size laboratories which don’t feel very comfortable investing in a CISPR 16-1-1 Full-Compliant Receiver for Radiated Frequency Range too.
In practice, to perform truly Full Compliant Radiated Emission Tests, an appropriate test site should be made available for hosting both EUT (Equipment Under Test) and Receiving Antenna separated by 3, 10 or even 30 meters distance, like SAC (Semi-Anechoic Chambers) or OATS (Open Area Test Sites), this usually means an huge investment in terms of RF shielding and absorbing materials.
Nevertheless, with appropriate methodology and care to discriminate as much as possible noise contributions coming from the environment vs. those generated by the EUT, it’s also possible to perform good evaluative radiated emission tests in an Open Space with a Pre-Compliant Receiver and this is exactly the purpose 9010/30P has been designed for in the range 30 - 3000 MHz. On the other side, looking to Conducted Emissions Tests requirements, Full Compliance toward each specific Product Standard can be easily fulfilled with a significantly lower budget investment, i.e. no specific environment is required but only few components (EMI Receiver, LISN or High Voltage Probe, etc.), and that’s why having a Full Compliant Receiver for the range 9 kHz - 30 MHz becomes really convenient just comparing its cost to that of tests performed in a 3rd party laboratory.
In few words, with PMM 9010/30P the mix of Full and Pre-Compliant features provides a perfect match to practical testing requirements, not excluding the possibility of future upgrades to 100% CISPR 16-1-1 Full-Compliance up to 3 or 6 GHz or 18 GHz with simple addition of PMM 9030 or PMM 9060 or PMM 9180 extension units digitally connected through fiber optic cable. All other features provided by previously released PMM 9010 Full-Compliant Receiver remains unchanged in 9010/30P too, including optional Click Analyzer Function and MIL-STD 461 Filters.
The already widely appreciated software “PMM Emission Suite” can properly control 9010/30P as well.
MAIN FEATURES • 0,8 to 6 GHz frequency range
• Excellent flatness
• Tripod mounting

EHP-TS - New Software for EHP-50C and EHP-200A management
The software EHP-TS allows management by Personal Computer of electromagnetic field analyzers Narda mod. EHP-50C and EHP-200A.
The fiber optic cable, coming from the field analyzer (max length 40m), is connected to a USB port on your PC via the USB adapter-OC supplied.
The graphical interface of the program allows you to set all parameters of measurement. The commands are grouped into five selectable sections while the measure of spectral analysis is displayed and updated continuously.
It is possible to view on the same graph the measure of both, electric and magnetic fields.
The program sections Sweep, Mode, Limit and Aspect allow parameters setting while Section Data, equipped with controls to manage Marker, displays the numerical results as the field strength, the frequency corresponding to the position of the Marker and the higher peak from the spectral display. The broadband result is also displayed, it is the quadratic sum of all contributions within the frequency band shown.
The curves of the ICNIRP reference levels are already available while using the "Make Limit" You can create custom limits.
The results can be displayed with different units of measure or as a selectable percentage of the threshold applied.
The measures, complete with personalized feedback, can be saved in graphic form and as text files (txt) in order to be easily imported into other applications such as spreadsheets or word processors.
The application management of the EHP-200 analyzer can show the spectrum of the density of power expressed in W/m2 or mW/cm2.
It is common practice to display the power density as a calculation result that uses related units (intensity of magnetic field calculated on the basis of an electric field). This practice is acceptable only in a distant field.
The spectrum of the power density displayed by EHP-TS in "Dual" mode is calculated based on actual measures of electric and magnetic fields, for this reason it can be used either in far field and near field conditions.
The field measurements for the evaluation of safety in the workplace can be made in this way with minimal effort and high reliability.
The availability of very compact devices with Windows operating system, such as UMPC and similar, make the software EHP-TS ideal for performing measurements with spectral analysis on the ground in a smooth and light equipment.
The EHP-TS software is composed of the following applications:
EHP50 TS: spectral analysis measure management on a PC with EHP-50C analyzer. EHP50C - Stand Alone mode: setup / download of data for measurements carried out by EHP-50C in "stand alone mode" (no connection to the probe). EHP-50 Firmware Update: utility for EHP-50C analyzer firmware update. EHP200 TS: spectral analysis measure management on a PC with EHP-200 analyzer EHP-200 Firmware Update: utility for EHP-200 analyzer firmware update. Uninstall EHP-TS: Procedure to uninstall the EHP-TS package.
