5-6 Analyzer Mode Operating Instructions
5.4.5 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.
5.5 Marker
With this command the Marker function can be enabled.
Switching ON the marker it appears on the screen as a small black
pointing down arrow, and simultaneously a small window shows up in the
bottom left corner of the screen, indicating the actual frequency and level
read by the marker.
Pressing the
Peak button the marker will automatically move to the highest
signal found in the span range in that given moment, and with the help of
the
Center button the frequency selected by the marker becomes the
center frequency on the screen, making very easy any signal analysis.
5.6 ESC This button allows to return to the previous view or condition.
