Performs limit testing on the input spectrum using a variable limit.

The input spectrum.

Start frequency, in Hz, of the spectrum.

**Default: **0

Frequency resolution, in Hz, of the spectrum.

**Default: **1

Spectrum of the input signal.

Upper limit that bounds the limit testing.

Minimum value of the *x*-axis.

**Default: **0

The interval between points on the *x*-axis.

**Default: **1

Y-axis values for the limit.

Lower limit that bounds the limit testing.

Minimum value of the *x*-axis.

**Default: **0

The interval between points on the *x*-axis.

**Default: **1

Y-axis values for the limit.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an **error in** input and an **error out** output so that the node can respond to and communicate errors that occur while code is running. The value of **error in** specifies whether an error occurred before the node runs. Most nodes respond to values of **error in** in a standard, predictable way.

**Default: **No error

Pass region for the limit test and whether to include the limit values in the region.

Region where signal points fall that passes the limit test.

Name | Value | Description |
---|---|---|

inside limits | 0 | The signal is within lower limit and upper limit. |

outside limits | 1 | The signal is not within lower limit and upper limit. |

**Default: **inside limits

Locations of failed test points.

*x*-value locations of failed test points.

*y*-value locations of failed test points.

Upper and lower limits, the input signal, and the failures.

Minimum value of the *x*-axis.

The *x*-axis interval between points in the limit.

Y-axis values for the limit.

Error information.

The node produces this output according to standard error behavior.

Measurement of distance between the signal and upper limit and lower limit.

Minimum distance between the signal and the upper limit.

Minimum distance between the signal and the lower limit.

Minimum, overall distance between the signal and the limits.

**min clearance** is the minimum of **clearance upper limit** and **clearance lower limit**.
