:FUNCtion CRECovery Commands

Command Syntax

:FUNCtionN:CRECovery:DDRFive:DQSSource <source_waveform>

Where N identifies one of sixty four {1:64} math functions that you can create. For example, :FUNCtion2.

Where <source_waveform> can be one of the following:

  • CHANnel{N} — Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is CHANnel4_2.
  • DIFF{N} — Where N identifies a specific differential waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 differential waveform 3 (from the pairing of channels 3 and 4) is DIFF5_3.
  • CMODe{N} — Where N identifies a specific common-mode waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 common-mode waveform 3 (from the pairing of channels 3 and 4) is CMODe5_3.
  • FUNCtion{1:64}
  • WMEMory{1:8}

Query Syntax

:FUNCtionN:CRECovery:DDRFive:DQSSource?

Description

When an DDR5 clock recovery mode is selected (see :FUNCtion:CRECovery:MODE), this command specifies the input source of the DQS (Strobe) waveform.
