4.2.3 Conversion factor
When using a transducer to make a measurement – a Voltage or Current
Probe, an Antenna, etc. – there is always the need to add to the measured
values the conversion factor of the transducer in use.
The Conversion factor may also take proper account of losses as cable loss,
attenuators added externally to the receiver, etc.
The PMM 9010 can handle these factors in an automatic way and directly
correct the readings.
The PMM 9010 can store in its internal non-volatile memory up to 4 different
correction factors, and use them one at a time when recalled.
However, the
Conversion Factors
shall be created and loaded via the PMM
9010 Software Utility.
Press the relevant button to load the conversion factor, and
NONE
to unload
it.
4.3 Limit
Each emission standard has one or more limits the User shall comply with.
The PMM 9010 receiver has the possibility to load and activate one limit with
the simple click of a button.
The preloaded standard limits refer to the most popular EMC emission
standards: CISPR22, CISPR14 and CISPR11.
Other limits – or any custom designed limit – can be created, managed,
selected and loaded through the PMM 9010 Software Utility running on a PC
(and the test, of course, shall be handled via the PC software).
These additional custom limits cannot be stored in the memory of the PMM
9010, but only in the one of the PC where the 9010SW Utility is running.
The limits are shown on the scan display and they appear like a thin black
line when the Smart Detector function is not enabled, while one of them
appears in bold black when the Smart Detector function is active.
By pressing the NONE button all limits are deactivated.
4.4 Display
Pressing the
Display
button it is possible to set two parameters: the
visualized
Dynamic
range
(chosen between 80, 100 and 120dB) and the
Reference Level,
that can be increased or reduced by steps of 5dB within
the range +80 dB
µ
V to 135 dB
µ
V (-25 to +30 dBm); see also 4.2.
