frequency value up to the deviation value set via the SCPI command

SENSe2:FREQuency:CDR:SSCLocking:DEViation[?]
SENSe2:FREQuency:CDR:SSCLocking:DEViation <NR3>
SENSe2:FREQuency:CDR:SSCLocking:DEViation?
Sets/gets the amount of spread spectrum clocking,in percent, that the CDR can
follow. The allowed values are between 0 and 0.5. The interval is defined
asymmetrically; for a value of e.g. 0.3, the clock may vary between the nominal
CDR frequency, and 99.7% of this value (i.e. a deviation of -0.3%). The clock may
not be above the nominal CDR frequency. The example is valid for the default
DOWNspread.
SENSe2:FREQuency:CDR:SSCLocking:DEViation:TYPE[?]
SENSe2:FREQuency:CDR:SSCLocking:DEViation:TYPE[?] DOWNspread |
UPSPread | CENTerspread
SENSe2:FREQuency:CDR:SSCLocking:DEViation:TYPE?
This command specifies the way the frequency of the incoming signal will be
modulated. It can DOWNspread, UPspread or CENTERspread. DOWNspread is the
default deviation value.

SENSe2:FREQuency:CDR:TDENsity[?]
SENSe2:FREQuency:CDR:TDENsity <NR3>
SENSe2:FREQuency:CDR:TDENsity?
Sets/gets the transition density of the incoming signal, in percent. The allowed
values are between 25 and 100. This value is internally used by the CDR to adjust
its gain for locking on the incoming data.
Example: A 1010 pattern has a transition density of 100%, while a 1100 pattern
has a transition density of 50%.
