get(timingReference=TimingReference.Default) → PulseSlope[source]
# TREFerence<*>:EDGE
value: enums.PulseSlope = driver.treference.edge.get(timingReference = repcap.TimingReference.Default)

Sets the clock edges that are used for measurements if method RsMxo.treference.typePy.set() is set for the indicated measurement. Sets the data edges for clock data recovery if method RsMxo.treference.typePy.set() is set for the indicated measurement.

Parameters:

timingReference – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Treference’)

Returns:

edge: 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 signals with bit start at the negative clock edge.

  • EITHer: Can be used for double data rate (DDR) signals and clock edges. For data edges, it is the most common setting.

set(edge: PulseSlope, timingReference=TimingReference.Default) → None[source]
# TREFerence<*>:EDGE
driver.treference.edge.set(edge = enums.PulseSlope.EITHer, timingReference = repcap.TimingReference.Default)

Sets the clock edges that are used for measurements if method RsMxo.treference.typePy.set() is set for the indicated measurement. Sets the data edges for clock data recovery if method RsMxo.treference.typePy.set() is set for the indicated measurement.

Parameters:

  • edge –

    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 signals with bit start at the negative clock edge.

    • EITHer: Can be used for double data rate (DDR) signals and clock edges. For data edges, it is the most common setting.

  • timingReference – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Treference’)
