Specify the error detector test pattern
From the Analyze menu, select Serial Error Detector, press Setup, and then select the Test Pattern tab. Error detector is not
available on DPO70000SX instruments.
Overview
The Test Pattern Setup provides control of the signal test pattern length and the Sync Pattern description. These are often the
most difficult settings, because they require knowledge of the signal. The Pattern Length is the number of bits in the repeating
signal being sent to the DUT or oscilloscope by the signal generator or AWG. The Sync Pattern is a 10-, 20-, 30-, or 40-bit unique
pattern in the signal that the error detector uses to align the signal to the acquired comparison pattern. The Advanced check box
just allows you to set the Disparity of each of the Sync Pattern symbols individually. The ‘X’ means “don’t care.” The Preset
Setups set these parameters to make the job easier for the common cases.
To use
■
Specify the Sync Pattern, Sync Pattern Polarity, and the Pattern Length.
NOTE. Signal test patterns may be 800 to 100K bits in length, modulo 40, e.g. 800, 840, 880, 920….
