:DIFF:CRECovery:CFRequency:EDIRection

Command Syntax

:DIFFN:CRECovery:CFRequency:EDIRection {RISing | FALLing | BOTH}

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.

:DIFFN:CRECovery:CFRequency:EDIRection?

Description

Specifies the edge(s) of a signal you would like to use to recover the clock. Typically, for all clock recovery methods except Explicit, you would use BOTH edges of a signal to recover a clock. However, the other options are available if, for example, the signal is a clock signal with a low duty cycle and you want to measure jitter only on its RISing (or FALLing) edges.
