Description

The Series R block models the series resistor described in the block dialog box, in terms of its frequency-dependent S-parameters.

The series R object is a two-port network, as shown in the following circuit diagram.

Parameters

Main

Resistance (ohms) — Resistance value

1 (default) | scalar

Resistance value, specified as a scalar.

Visualization

Source of frequency data — Frequency data source

User-specified (default)

Frequency data source, specified as User-specified.

Frequency data (Hz) — Frequency data range

[1:1.0e5:4e6] (default) | vector
