–223 Too much data; 200 
spurs found. 
Additional spurs 
ignored.
There are too many spurs for the table (the limit is 200), and any additional 
spurs that are found will be ignored
–224 Illegal parameter 
value
An exact data value (from a list of the allowed values) was required, but not 
found. See the specific feature description for information about the expected 
parameter values
–224 Illegal parameter 
value; <Value> 
invalid. Fractional 
values are not 
allowed.
The seconds parameter of an LXI time may not contain a fractional portion. For 
example 123456789.0 is valid, but 123456789.1 is not valid
–224 Illegal parameter 
value; <value> out of 
range.
The value does not fall within the valid range
–224 Illegal parameter 
value; Exceeding the 
max list length
The list parameters have a maximum allowed length. You are trying to set a 
length longer than the maximum
–224 Illegal parameter 
value; Gated FFT is 
not available while 
Sweep Type is set to 
Swept
The gated FFT function is not available if you have selected the swept type of 
sweep. You must select the FFT sweep type
–224 Illegal parameter 
value; Gated LO is 
not available while 
Sweep Type is set to 
FFT
The FFT sweep type moves the LO frequency in steps, so the gated LO function 
is not available if you have selected FFT sweep
–224 Illegal parameter 
value; Gated Video is 
not available while 
Sweep Type is set to 
FFT
The gated video function is not available if you have selected the FFT sweep 
type
–224 Illegal parameter 
value; Illegal 
identifier 
<identifier>. This 
value may already be 
in use.
The value for the LXI LAN identifier parameter must be unique (that is, LAN0 
and LAN7 must have different identifier strings)
–224 Illegal parameter 
value; Index out of 
range
When querying the LXI Event Log or the Servo Log, an index may be used to 
look at a specific entry. This error occurs if the index provided does not point to 
a valid entry
