BETTER INTRINSIC UNCERTAINTY
Differently from analogue receivers, in the PMM 9010 & 9030-9060 there are less parts contributing to the overall uncertainty. The result is a superior performance stability during time. the following table shows a cross-comparison with a typical analogue receiver .
IMPROVEMENT OF OVERALL ACCURACY
The following picture shows a real case of comparison between antenna-receiver connected by coaxial cable (blue trace) and PMM 9030 directly connected to the antenna and linked to PMM 9010 by fiber optic cable (pink trace).
PMM’s solution can prevent unwanted signals being picked up by the coaxial cable along its path from the antenna to outside the chamber, as well as the long path cable losses.
In all operation modes PMM Digital Receivers dramatically improve the test speed:
- Sweep mode, band A (9 to 150 kHz) : prior to apply the long time-consuming test as required by CISPR, the user can take advantage of the huge internal memory of the mod. 9010 and FFT (Fast Fourier Transform) technique to obtain a complete scan of the band A in only 1 second, even with the CISPR 200 Hz RBW filter weighting and detectors.
Then, only those peaks exceeding the selected limits will be measured in standard mode, thus saving a great deal of time. This function is particularly useful with those EUT like many appliances and electric tools that are switched on for short time, not measurable in conventional sweep mode.
- Sweep mode, all bands up to 6 GHz
A clever function - the Smart Detector - that was first introduced in PMM’s receivers in1990 allows the receiver starting scanning with the fast peak detector; as soon as the reading is close to a threshold - corresponding to a selected limit, or limit with offset - it immediately turns to the Quasi-peak detector - or any other selected -, moves some frequency step back and starts sweeping again with the new detector until the levels remain over the preset threshold. Then the receiver turns back in peak mode and continues the scan at the highest possible speed, repeating this process any time there’s an over limit peak .
- Analyzer Mode
The receiver performs spectrum analyzer functions but with the optimized response to pulsed signals characteristic of an EMI receiver; the very high scan speed (<100 ms for full-span 9 kHz - 30 MHz @ IF resolution 300 kHz) makes it ideal for any kind of debugging.
INTERNAL CALIBRATION SOURCE AND TRACKING GENERATOR
To maintain calibration a signal reference is essential: a high stability internal RF Signal Generator (60 to 90 dBµV in 0,1dB steps) is included in PMM 9010.
This RF generator can also work in tracking mode with the span or set at any frequency in the range of 10 Hz to 50 MHz, thus making the receiver an easy to use scalar network analyzer for characterizing components, antennas,
APD is a statistical characterization of signals recently introduced for testing above 1 GHz. It’s based on a scan of selected spans and measurements on several frequencies with Peak detector and Max Hold, then frequencies that show highest disturbance levels are sorted and compared with the limits for a given “Probability”.
This requires the receiver featuring outstanding hardware with high dynamic, huge memory and ultra-fast computation capabilities.
Test Engineers can select the most convenient test approach: fully automatic, semiautomatic, manual, etc.
APD as a standard feature of PMM’s EMI receiver model 9010 and 9030 – 9060 frequency extension units.
Universal kit for mounting PMM 9030 and PMM 9060 directly on the antenna connector
the receiver can be operated as stand-alone by thefront knob and soft keys through user-friendlymenus, or remotely by a PC connected via USB orRS232 Serial interface (Bluetooth optionally).
Rechargeable/Replaceable internal batteries
for enhanced portability and for field (in situ) tests, offering also the major advantage to be completely disconnected from the mains in critical analysis, for measurements not influenced at all in hostile or noisy environments.

Max. length: 100 m
Click Meter option
allows the User to perform click tests in a straightforward and easy way.
PMM 9010 takes care of everything: evaluation of the Click Rate N; applicable exceptions; Click measurement using Upper Quartile Method; Full Report with all mandatory data.
PMM 9010 fully supports the new standard dealing with all the allowed four exceptions , showing in real time all the events including click details and reporting all mandatory and optional data to make a detailed report. It shall be noted that the handling of E-3 is the most demanding in terms of hardware and software, however it is also the exception that is more beneficial for the customer, as it allows to completely skipping unnecessary tests. In general, the first investigation is terminated as per one of the required events listed in the standard: after 40 clicks; after the standard 120 minutes; after a specific time span; manually; paused and resumed to allow restarting recursive EUT programs. Moreover, PMM 9010 has the unique feature “Smart Measure” that can dramatically speed up the Click test: another productivity feature by Narda STS.
