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

Query Syntax

:FUNCtionN:PATTern:MODE?

Description

For data measurements like BER/SER (Bit/Symbol Error Ratio) where the measurement must know the pattern of a data signal, this command selects how the pattern is determined:

  • ADETect — (Auto Detect) This option tells the oscilloscope to automatically determine the pattern length and pattern by looking for at least two error-free copies of an identical repeating bit pattern in acquisition memory.

  • KPATtern — (Known Pattern) This option lets you select the pattern from a list of known patterns (see :FUNCtion:PATTern:KPATtern).

  • PFILe — (Pattern File) This option lets you load a pattern file that tells the oscilloscope the pattern length and pattern to measure against.

    Use the :FUNCtion:PATTern:FILE:NAME command to select the pattern file.
