14-16 Remote control
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 31
• 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 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 SLIE
Here is an example how to make a custom limit on PMM9010:
•
#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 point, 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.
SMAF f This setting command sets the tuning frequency for manual mode. The string (f) can
be in exponential form and should be expressed in Hz. The reply is
MAF=OK which
acknowledges the command has been granted or MAF=SERR if the command has
been ignored.
When the command is granted the 9010 goes to manual mode automatically
Example:
#SMAF150e3* Sets the manual frequency to 150kHz
SMAN This setting command puts the 9010 in manual mode. The reply is always MAN=OK
which acknowledges the command has been granted.
The 9010 goes to manual mode.
Example:
#SMAN *
SMANP This setting command puts the 9010 in manual mode and sets the default value to
the following settings:
• RBW Automatic
•
Attenuator Automatic
•
MinAtt=10 dB
• Preselector On
•
Preamplifier OFF
•
Hold Time =1000ms
• Pulse Limiter = OFF
•
TG=OFF
The reply is always MANP=OK which acknowledges the command has been
granted.
The 9010 goes to manual mode.
Example:
#SMANP*
