This command triggers a free sweep (no automatic items are selected) based on the
provided parameters. After this command has been received, all parameters issued
in the command itself are checked out and, if coherent, a sweep starts otherwise the
related error is notified and the sweep is not triggered.
After the command has been received, the ER9000 replies by sending a string which
reflects the status of parameters check as follows:
•
SFD=OK <CR><LF> No error in parameters and sweep started.
•
SFD=ERR 1 <CR><LF> An Error was found in start or stop frequencies. Errors
can be one of the following:
o
Start Frequency lower than minimum allowed frequency
o
Stop Frequency higher than maximun allowed frequency
o
Start Frequency higher than Stop Frequency
•
SFD=ERR 2 <CR><LF> An Error was found in step frequency. Step is either
o
Too small.
o
Is equal to zero (use of Frequency-Scan-Tab) but there are less than two
frequencies in the table
•
SFD=ERR 3 <CR><LF> An Error was found in detector . Errors can be one of
the following:
o
Invalid Detector or no detector found. Detectors must be indicated by
‘P’,’Q’,’R’,’A’,’N’ and ‘S ’ only
o
Smart Mode selected but no active limit
o
Smart Mode selected but no alternative detector
o
Smart Mode selected but more than two alternative detector indicated
•
SFD=ERR 4 <CR><LF> An Error was found in HoldTime value. HoldTime is
either too big (>30s) or negative.
•
SFD=ERR 5 <CR><LF> An Error was found in RBW . Errors can be one of the
following:
o
Unsuitable RBW for the active unit (for instance 200 Hz RBW while
operating in bands C, D and E)
o
Unsuitable RBW for the detector previously selected (for instance 100 kHz
RBW and QuasiPeak selected).
•
SFD=ERR 6 <CR><LF> An Error was found in MinAtt value. Errors can be one
of the following:
o
MinAtt value is negative
o
MinAtt value is higher than maximum available attenuation
o
MinAtt value is not in step of 5
•
SFD=ERR 7 <CR><LF> An Error was found in Preamp string. Preamp string
can be either ON or OFF only. String is not case sensitive.
•
SFD=ERR 8 <CR><LF> An Error was found in Preselector string. Preselector
string can be either ON or OFF only. String is not case sensitive.
•
SFD=ERR 20
<CR><LF> An Error was found in the
Frequency Step
.
Step is
too small.
•
SFD=ERR 101 <CR><LF> A generic Error was found.
•
SFD=ERR 102 <CR><LF> A generic Error was found.
•
SFD=ERR 103 <CR><LF> Radiated Sweep Mode required but RF Module not
yet ready. Please refer to command ?RFS.
