Remote control 14-23
SSFW n, freq
This setting command is used for creating a Frequency-Scan-Tab frequency by
frequency. It is made of two fields as follows:
• n Is the index of frequency being written and it should range from 0 to 99
• freq Is the frequency, expressed in Hz (exponential notation allowed), being
written
The procedure to make and use a Frequency-Scan-Tab on PMM9010 is the
following:
• Send as many commands SSFW as frequency points of table are in
upwards order.
• Send the command SSFD with step size set to zero
Here is an example how to make a Frequency-Scan-Tab on PMM9010:
• #SSFW 0, 150e3 * Set the first freq to 150kHz
• # SSFW 1, 500e3 * Set the second freq to 500kHz
• # SSFW 2, 5e6* Set the third freq to 5MHz
• # SSFW 3, 6e6* Set the fourth freq to 6MHz
• # SSFW 4, 30e6 * Set the fifth freq to 30MHz
Note that all the higher indexes in the Frequency-Scan-Tab are cleared. Therefore, a
Frequency-Scan-Table must be made in upwards order. All points, having a higher
index previously written, are cleared.
Note that only the present frequencies will be tuned and measured as all remaining
will be completely neglected. Hence, it is responsibility of the user to make sure
the data sent are correct and coherent.
The reply is SSFW =OK which acknowledges the command has been granted or
SSFW =SERR if the command has been ignored.
SSHT h
This setting command sets hold time for Sweep mode. The string (h) should be
expressed in ms. The reply is SHT=OK which acknowledges the command has
been granted or SHT =SERR if the command has been ignored.
Note that the Hold Time is automatically changed when detector is set to Smart
mode. In this case when the command SSDT is received the Hold Time = Min (Hold
Time, 1000). If one wants to set it lower than 1000 in smart mode, the user should
send the hold time command (SSHT) later than SSDT command.
Example: #SSHT 1500* Sets the hold time, for Sweep mode, to 1500 ms (or 1.5s)
SSOP f
This setting command sets the Stop frequency for Sweep mode. The string (f) can
be in exponential form and should be expressed in Hz. The reply is SOP=OK which
acknowledges the command has been granted or SOP =SERR if the command has
been ignored.
Example: #SSOP 10e6* Sets the Stop frequency, for Sweep mode, to 10MHz
SSPA a
This setting command switches Preamplifier, for Sweep Mode, according the
parameter (a) which can be either On or OFF.
The reply is SPA=OK which acknowledges the command has been granted or SPA
=SERR if the command has been ignored.
Example: #SSPA ON*
Example: #SSPA OFF*
SSPS a
This setting command switches Preselector, for Sweep Mode, according the
parameter (a) which can be either On or OFF.
The reply is SPS=OK which acknowledges the command has been granted or SPS
=SERR if the command has been ignored.
Example: #SPS ON*
Example: #SPS OFF*
