Specifies whether to enable the traces to be stored and retrieved after performing the SlotPhase measurement.
SlotPhase:Measurement Enabled
Specifies whether to enable the SlotPhase measurement.
SlotPhase:Measurement Length (slots)
Specifies the duration of the SlotPhase measurement. This value is expressed in slots.
SlotPhase:Measurement Offset (slots)
Specifies the measurement offset to skip from the synchronization boundary. This value is expressed in slots. The synchronization boundary is specified by the SlotPhase Sync Mode property.
SlotPhase:RRC Filter Enabled
Specifies whether to enable the RRC filter. Use this property to disable the filter if the received signal is already RRC-filtered.
SlotPhase:Results:Discontinuity Count > Limit 1
Returns the number of times the phase discontinuity values exceed the Limit 1 value for the acquired signal. Limit 1 is fixed at 36 degrees.
SlotPhase:Results:Discontinuity Count > Limit 2
Returns the number of times the phase discontinuity values exceed the Limit 2 value for the acquired signal. Limit 2 is fixed at 66 degrees.
SlotPhase:Results:Discontinuity Minimum Distance (slots)
Returns the minimum distance between two phase discontinuity measurements exceeding the Limit 1 value. Limit 1 is fixed at 36 degrees. This value is expressed in slots.
SlotPhase:Results:Maximum Phase Discontinuity (deg)
Returns the maximum of all the measured phase discontinuity values at the slot boundaries.
SlotPhase:Spectrum Inverted
Specifies whether the signal spectrum is inverted.
SlotPhase:Synchronization Mode
Specifies whether the measurement is performed from the frame or the slot boundary.
SlotPhase:Transient Removal Enabled
Specifies whether the SlotPhase measurement excludes 25 microseconds from the start and end of each slot while computing the linear-fit chip phase error, which is used to compute phase discontinuities at the slot boundaries.
SlotPower:Measurement Enabled
Specifies whether to enable the SlotPower measurement.
SlotPower:Measurement Length (slots)
Specifies the duration of the SlotPower measurement. This value is expressed in slots.
SlotPower:Measurement Offset (slots)
Specifies the measurement offset to skip from the synchronization boundary. This value is expressed in slots. The synchronization boundary is specified by the SlotPower Sync Mode property.
SlotPower:RRC Filter Enabled
Specifies whether to enable the RRC filter.
SlotPower:Spectrum Inverted
Specifies whether the spectrum of the signal is inverted.
SlotPower:Synchronization Mode
Specifies whether the measurement is performed from the frame or slot boundary.
Trigger:Delay (s)
Specifies the trigger delay time.
Trigger:Digital Edge:Edge
Specifies the active edge for the trigger.
Trigger:Digital Edge:Source
Specifies the source terminal for the digital edge trigger.
Trigger:IQ Power Edge:Level (dB or dBm)
Specifies the power level at which the device triggers.
Trigger:IQ Power Edge:Level Type
Specifies the reference for the IQ Power Edge Level property.
Trigger:IQ Power Edge:Slope
Specifies whether the device asserts the trigger when the signal power is rising or when it is falling.
Trigger:IQ Power Edge:Source
Specifies the channel from which the device monitors the trigger. This property is used only when you set the Trigger Type property to IQ Power Edge.
Trigger:Minimum Quiet Time:Duration (s)
Specifies the time duration for which the signal must be quiet before the signal analyzer arms the I/Q power edge trigger.
Trigger:Minimum Quiet Time:Mode
Specifies whether the measurement computes the minimum quiet time used for triggering.
Trigger:Type
Specifies the trigger type.
