This setting command sets the volume of demodulator. The string (v) should be in
SDMV v
the range of 0 to 100.
The reply is DMV =OK which acknowledges the command has been granted or DMV
=SERR if the command has been ignored.
Example: #SDMV 50* Sets the volume of demodulator to half of the audio power.
SLDW n,freq; This setting command is used for setting the custom double value limit frequency by
frequency. It consists of four fields as follows:
levq,leva
The purpose of this command is to have a double value limit that can be used along
with smart detector function when sweeping by the command SSFD:
The procedure to set a custom double value limit on PMMER8000 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 PMMER8000:
• #SLDW 0, 150e3; 66,56 * Send the first line 150kHz 66 dBµV (QP)
• #SLDW 1, 500e3; 56,46 * Send the second line 500kHz 56 dBµV (other det.)
• #SLDW 2, 5e6; 56,46 * Send the third line 5MHz 56 dBµV
• #SLDW 3, 5e6; 60,50 * Send the fourth line 5MHz 60 dBµV
• #SLDW 4, 30e6; 60,50 * Send the fifth line 30MHz 60 dBµV
• #SLIE Custom Double * 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 SLDW =OK which acknowledges the command has been granted or
LDW =SERR if the command has been ignored.
This setting command is used for naming the custom limit and making it active or
SLIE name
deactivating it. The command is made of the string LIE (the command itself) and a
string which represents the name of the limit it will be shown.
It is suggested a name of maximum 10 characters.
Sending a LIE with no argument (Limit name) deactivates all limit active, if any. This
command is intended for making a custom limit into PMM ER8000. For further
information see command SLIW.
When the command is received the limit is checked and, if data (frequency and level)
are coherent, the command is granted by replying SLIW =OK otherwise the replay is
SLIW =SERR
Example: # SLIE Custom Limit* checks the data previously loaded by SLIW
commands, names the limit as "Custom Limit" and activates it
Example: # SLIE * deactivates any limits
•
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
•
levq Is the level of the limit which refers to QPeak and is expressed in dBµV
•
leva Is the level of the limit which refers to the alternate detector and is
expressed in dBµV
