MEASurement<*>:JITTer:CDRMode

Commands in total: 1

Subgroups: 0

Direct child commands: 1

get(measurement=Measurement.Default) → CdrMode

# MEASurement<*>:JITTer:CDRMode
value: enums.CdrMode = driver.measurement.jitter.cdrMode.get(measurement = repcap.Measurement.Default)

Defines the origin of the clock signal - wether a real clock signal or a clock generated using one of the CDR methods. The command is available for the following measurements: time-interval error, unit interval and data rate (method RsRtx.measurement.main.set() and/or method RsRtx.measurement.additional.set() are set to measurements TIE | UINTerval | DRATe) .

Parameters:

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

Returns:

jitter_cdrm_ode: SIGNal | SW1 | SW2 | SW3 | SW4 | | HW

• SIGNal: The clock is a real clock signal.

• SW1 | SW2 | SW3 | SW4: The clock is generated by a software algorithm. You can define two software algorithms for CDR. To configure the CDR, use the CDR:SOFTware commands.

• 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)

set(jitter_cdrm_ode: CdrMode, measurement=Measurement.Default) → None

# MEASurement<*>:JITTer:CDRMode
driver.measurement.jitter.cdrMode.set(jitter_cdrm_ode = enums.CdrMode.HW, measurement = repcap.Measurement.Default)

Defines the origin of the clock signal - wether a real clock signal or a clock generated using one of the CDR methods. The command is available for the following measurements: time-interval error, unit interval and data rate (method RsRtx.measurement.main.set() and/or method RsRtx.measurement.additional.set() are set to measurements TIE | UINTerval | DRATe) .

Parameters:

• jitter_cdrm_ode –

  SIGNal | SW1 | SW2 | SW3 | SW4 | | HW

  • SIGNal: The clock is a real clock signal.

  • SW1 | SW2 | SW3 | SW4: The clock is generated by a software algorithm. You can define two software algorithms for CDR. To configure the CDR, use the CDR:SOFTware commands.

  • 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)

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