Remote control 14-13
SCFE n, name This setting command is used for saving the conversion factor (made by SCFW) .
The command is made of the string:
•
FCE (the command itself),
•
n which is the index:
o
From 1 to 4 saves into permanent memory
o
0 uses the factor temporarily
•
name which is a string representing the name of it
This command is intended for creating a conversion factor into PMM9010. For
further information see command
SCFW .
When the command is received the conversion factor is checked and, if data
(frequency and level) are coherent, the command is granted by replying
SCFW
=OK otherwise the replay is SCFW =SERR
Example:
#SCFE 2,Probe* checks the data previously loaded by SCFW
commands, names it as “Probe ” and saves it as #2.
SCFW n, freq; lev
This setting command is used for creating a conversion factor 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 499
• freq Is the frequency, expressed in Hz (exponential notation allowed),
being written
•
lev Is the level of the limit and is expressed in dB
The procedure to creating a conversion factor on PMM9010 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 SFCE
Here is an example how to make a custom limit on PMM9010:
• #SFCW 0, 150e3; -1 * Send the first line 150kHz -1 dB
•
# SFCW 1, 500e3; 0 * Send the second line 500kHz 0 dB
•
# SFCW 2, 5e6; 1.2 * Send the third line 5MHz +2 dB
• # SFCW 3, 50e6; 1.1 * Send the fourth line 50MHz +1.1 dB
•
# SFCW 4, 300e6; 1 * Send the fifth line 1 dB
• #SCFE 2,Probe* Save it permanently as #2 into 9010 and name it as
“PROBE”
Note that all the higher indexes in the conversion factor are cleared. Therefore, a
conversion factor must be made upwards 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
SCFW =OK which acknowledges the command has been granted or
LCFW =SERR if the command has been ignored.
