Remote control 7-17
SLIM n
This setting command sets the Margin to be used with Smart Detector function. The
argument (n) in the range of -20 to 20.
The reply is
LIM =OK which acknowledges the command has been granted or LIM
=SERR if the command has been ignored.
Example:
#SLIM 2* Sets the threshold of smart detector to 2 dB below the limit.
SLIW
n,freq;lev This setting command is used for setting the custom limit frequency by frequency. It
consists of three fields as follows:
•
n Is the index of frequency being written and it should range from 0 to 15
•
freq Is the frequency, expressed in Hz (exponential notation allowed), being
written
•
lev Is the level of the limit and is expressed in dBµV
The procedure to set a custom limit on PMMER9000 is the following:
•
Send as many commands as the frequency points of limit are in
upwards order.
•
Terminate (and make it active) by sending the command SLIE
Here is an example how to make a custom limit on PMMER9000:
•
#SLIW 0, 150e3; 66 * Send the first line 150kHz 66 dBµV
•
#SLIW 1, 500e3; 56 * Send the second line 500kHz 56 dBµV
•
#SLIW 2, 5e6; 56 * Send the third line 5MHz 56 dBµV
•
#SLIW 3, 5e6; 60 * Send the fourth line 5MHz 60 dBµV
•
#SLIW 4, 30e6; 60 * Send the fifth line 30MHz 60 dBµV
•
#SLIE Custom CISPR 14-1 * Send the name and make the limit active
Note that all the higher indexes in the limit are cleared. Therefore, a limit must be made
in upwards order otherwise all points, having a higher index previously written, are
cleared.
It is
responsibility of the user to make sure the data sent are correct and coherent.
The reply is
SLIW =OK which acknowledges the command has been granted or LIW
=SERR if the command has been ignored.
