Technical data

Sets/gets the peaking of the CDR, in dB. The allowed values depend on both the

clock frequency of the CDR and its loop bandwidth, and can be queried with

SENS2:FREQ:PEAK:AVA? The peaking value will automatically change either after

the change in the CDR frequency or after the change of the loop bandwidth. Peaking

should be queried again by the remote program after such a change in the CDR

parameters.

SENSe2:FREQuency:CDR:PEAKing:AVAilable?

Gets a comma-separated list of allowed peaking values for the current CDR

settings. The command SENS2:FREQ:CDR:PEAK will only accept one of the the

values returned by this query. These values change either when the CDR frequency

or its loop bandwidth is modified. The values are expressed in dB.

SENSe2:FREQuency:CDR:RANGe?

IAgilentN490xEDCDR.GetRanges (not IVI-compliant)

SENSe2:FREQuency:CDR:RANGe?

Comma-separated list of CDR (Hertz) ranges: "min, max, min, max, min, max"

For example: 2.45e+009,3.21e+009,4.9e+009,6.42e+009,9.9e+009,1.09e+010

This indicates the following CDR ranges:

• 2.45 - 3.21 GHz

• 4.9 - 6.42 GHz

• 9.9 - 10.9 GHz

SENSe2:FREQuency:CDR:SSCLocking[?]

SENSe2:FREQuency:CDR:SSCLocking ON|OFF|0|1

SENSe2:FREQuency:CDR:SSCLocking?

Either enables or disables the CDR support for spread spectrum clocking. When

enabled, the CDR is able to extract a clock that deviates from the nominal CDR
