Frequency List

The Frequency List Sweep is a type of frequency sweep which may be added as a frequency entry in a Sweep Set in the Sweeps page of the Circuit Settings dialog box. A Frequency List sweep and the Frequency List window are pictured below followed by definitions of the control fields.

Frequency List allows you to enter a list of desired analysis frequencies in the Frequency List window. This is useful if you need multiple specific frequencies which are not related in a way which would allow you to use another sweep type. Each frequency is a floating point number and should be separated from the other frequency values using a comma, space or new line. If you wish to copy values from another source, perform a copy in the other source, then click on the Paste button. The copied values are added to the list. The frequencies do not need to be in numerical order, but you may click on the Sort button to sort all the values in the list from lowest to highest frequency.

If you are calculating a large number of frequencies, an Adaptive Sweep is often a more efficient way of calculating your response as an ABS sweep usually only requires a small number of analysis points to synthesize a fine resolution band. If you select the Adaptive checkbox at the end of the entry, em runs an Adaptive sweep, then synthesizes the response at the requested frequencies. Only the frequencies specified in the sweep are returned to the user.
