Affinity Additional Information
Note: Prior to creating a new test protocol you may wish to select a protocol
type in the Protocols to view dropdown list. This function is practical if you for
example wish to create a new protocol based on elements from the ANSI or
IEC standard. In this case the dropdown list can be used to select an ANSI
or IEC standard before clicking New. When asked if the new protocol should
be based on a copy of the currently selected protocol, click yes.

1) Ensure that Frequency Response is marked in the left hand side of the screen. The name of the
test will then appear in the Name of selected test section. Note the option to write a new name for
the test in this section (e.g. "Frequency Response 65 dB input")
2) Stimulus Selection:

Input Level: Set the input level using the slider.

Preconditioning: This is relevant when using broadband signals such as ICRA (see section
3.6.6.1 for details). Select a duration using the slider.

Stimulus type: Select a stimulus using the dropdown list (See stimulus list in section 3.12.1).

Sweep delays: This is relevant if Continuous measurement is selected for Pure Tone or Warble
Tone. In this case sweep delays (in milliseconds) may be entered between the individual
sweeps (see section 3.6.6.2 for details).

Start Frequency and Stop Frequency: Select the preferred frequencies using the sliders. To
avoid low frequency noise set the slider to a start frequency of 200Hz.
