Description

On the FP35 analyzer, this command is used to change the frequencies used in a pure-tone sweep or harmonic distortion test. You can also change the settle times per frequency for built-in or customized pure-tone sweeps. The first argument specifies what type of list is going to be specified. The next argument specifies how many frequencies are going to be included. Finally, the list of frequencies is given.

To set the settles times for a pure-tone sweep, first use this command to set the custom pure-tone sweep frequencies. Alternately, use the Set Stimulus Type command to change the source type to Normal, Fast, Short, or Long pure-tone sweep. Then use Set List to set the tone or I/O settle times for each tone. Normally the first tone in the sweep will have a longer delay time than the subsequent tones in the sweep.

The user frequency and distortion list is only used by the Do User Sweep command. Normal operation commands use the normal default frequency list.

On the 7000 analyzer, this command is used in the Visible Speech screen in order to set the list of Speech Intelligibility Index (SII) coefficients. This is the weights, in hundredths of a percent of the frequency bins. These weights are used when computing the SII value. The 7000 has not implemented the custom frequency sweeps or delay times on a per frequency basis as described above.

Note: As of software version 1.61, this command seems to have significant bugs on the 7000 analyzer.

On the 8000, this command is used in the Coupler Directional screen to:

Parameter 0: Set the Difference curve frequency list.

Parameter 4: Set the per frequency settling times for the Difference curve(if is is a tone curve).

Parameter 7: Set the list of Angles(times 64) used in the polar test.

Parameter 8: Set the list of Polar Settling times.

Note: Only the set Polar Angle list works in Ver 2.00.
