11.16.6 Load Store
Pressing this key allows the User to have access to the memory of the
receiver and enables the storing up to a number of different
configurations/sweeps that depends on the parameters set on the receiver.
For example, using standard CISPR parameters it is possible to store up to
5 sweeps on the C+D+E bands (RBW120 kHz and 1 MHz, respectively).
Each new scan will be stored in the first available memory position thanks to
the button
Store #x , where x is the first available position. When all positions
are occupied by a scan, this function is disabled until one of the previous
scan is erased.
To load a stored trace, press the
Load #x button until the proper scan is
displayed; to unload a trace select the Unload Trace button.
Please note that the Load function is scanning the memory in a circular way,
therefore all the occupied memory positions are shown in sequence. When
the key shows “Load #4”, it means the trace #3 is displayed and that the #4
will be loaded after the key is pressed, and so on and so forth.
To erase a trace, press the
Erase#x button .
Due to the structure of the memory, it is possible to erase only the latest
stored memory, with a sequence “LIFO” (Last In First Out), therefore after
having erased the #x, the #(x-1) will be the trace to be erased. With
reference to the example at the left, the last stored trace is the #4, and it is
the first that will be erased. After that, the key will show “Erase #3”, and so
on and so forth.
A more advanced trace management could be done using the PMM 9010
Software Utility.
Turn Off the tracking generator, if it is not used, while you are in Scan
Mode.
This prevents interferences and the measurements are more clean and
accurate.
