## Command Syntax

    :CHANnelN:SNDRatio:LFPLength <number_of_UIs>

<number_of_UIs> is an integer.

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`.

## Query Syntax

    :CHANnelN:SNDRatio:LFPLength?

## Description

This parameter is used in the filter to compute the linear fit pulse response. It is the length of the pulse fit, expressed as the number of unit intervals (UIs). It is sometimes denoted using Np.

Technology standard test documents typically tell you the value expected to be used for this parameter.
