13-6 APD Mode Operating Instructions
13.3.9 Time
Moving the highlighter cursor on the eleventh line of the Setup page the time
period for each frequency measurement after the sweep can be entered
using the function keys on the right.
The range for this value is between 2 and 120s.
When a value outside the range is entered the default 20s is automatically
set.
If a value higher of the one set for the Search Hold Time is entered, the
Search Hold Time is automatically adapted to the same duration.
13.3.10 Method
Moving the highlighter cursor on the twelfth line of the Setup page the
method for the measurement can be entered between Method 1 (E based -
default) and Method 2 (P based).
The choice is possible by pressing the Change Key.
13.3.11 Search Hold
Time
Moving the highlighter cursor on the thirteenth line of the Setup page the
time duration for the sweep search can be entered using the function keys
on the right.
The range for this value is between 2 and 1000s.
When a value outside the range, or lower then the Time parameter, is
entered the default 20s is automatically set or it is adapted to the Time
duration.
13.3.12 Conversion
Factor
Moving the highlighter cursor on the fourteenth line of the Setup page one of
the stored Conversion Factors can be chosen from the list on the right.
This functionality is useful when using a transducer to make a measurement
– a Voltage or Current Probe, an Antenna, etc. – as 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 (default).
13.3.13 Preselector
Moving the highlighter cursor on the fifteenth line of the Setup page the
internal Preselector filter can be activated (On, default) or deactivated (Off).
The choice is possible by pressing the Change Key.
