HW
The clock is generated from the source signal by the integrated
CDR circuitry. The HW CDR must be active to acquire the jitter
data (trigger type = CDR or serial pattern with CDR)
*RST: SW1
Usage: Asynchronous command
MEASurement<m>:JITTer:SOURce<n>:TIESlope <JitterTIESlope>
Sets the clock and data edges that are used for measurements. Clock or data is
defined by the SOURce suffix <n>.
The command is available for the following measurements: time-interval error, unit
interval and data rate (MEASurement<m>:MAIN and/or MEASurement<m>:
ADDitional are set to measurements TIE | UINTerval | DRATe.
Suffix:
<m>

<n> 1..2
1 = data slope (only relevant for time interval error measure-
ments with explicit clock signal)
2 = clock slope
Parameters:
<JitterTIESlope> POSitive | NEGative | EITHer
POSitive
The positive clock slope can be used, for example, for single
data rate (SDR) signals with bit start at the positive clock edge.
NEGative
The negative clock slope can be used, for example, for SDR sig-
nals with bit start at the negative clock edge.
EITHer
For clock edges, this option can be used for double data rate
(DDR) signals.
For data edges, it is the most common setting.

Usage: Asynchronous command
MEASurement<m>:JITTer:DRUNit <JittDatRateUnt>
Sets the unit for data rate measurements.
