Detailed Description

A 1-port resistor (terminator) that can be a power source.

The source frequency is held in source_f, source power in source_power, and the frequency width of the source is held in source_width. The power in source_power represents the power that would be delivered to a matched load resistance R at frequency source_f.

The default is to create an ideal power source, with perfect normalized impedance match R = Z0. Only a real resistance R can be specified for this device; if a complex impedance is required, use an ideal source and couple it to the circuit through a 2-port transformer with the desired matching impedance.

If the global frequency differs from source_f by more than source_width/2, then the source vector sdata::B will be set to 0.

Member Function Documentation

const nport::data_info & generator::get_data_info ( ) [virtual]

Returns: info about the sdata of the device Reimplemented from nport. Definition at line 60 of file sources.cc.

void generator::recalc ( ) [private, virtual]

The function for calculating sdata. recalc() should do the following: (1) Read device::f, device::Z0, and, by default, device::T to get the operating conditions for the response calculation. (2) Calculate the S, C, and B matrix values and store them to nport::data, with all values normalized using device::Z0. (3) Store the normalizing impedance to nport::data by calling data.set_znorm(). Reimplemented from nport. Definition at line 82 of file sources.cc.

void generator::recalc_S ( ) [private, virtual]

If the following function is implemented, it should only calculate the S matrix and B vector parts of data, leaving the C matrix part stale. Reimplemented from nport. Definition at line 67 of file sources.cc. Referenced by recalc().

int generator::size ( ) [inline, virtual]

Generators are 1-port devices. Returns: the number of ports Reimplemented from nport. Definition at line 114 of file sources.h.
