**@SteffanJvV,** You are correct. * Please change the category of this topic to Bug Report. **@UserSupport, ** The following describes the problem and what needs to be corrected to fix it. **Offset in the Rectangular and Triangle Wave outputs is not implemented correctly.** Both outputs of both waveforms are implemented using PULSE() sources. The low and high level output voltage of a PULSE() Source is defined by the **INITIAL** and **ON** parameters respectively. For an output with a peak to peak Amplitude, A, that swings equally A/2 above and A/2 below the Offset value, O, the expressions used to add an offset to the Pulse and Triangle Wave outputs should be: INITIAL=O-A/2 ON=O+A/2 **Offset in the Sine Wave output is implemented in an unexpected way.** For a function generator with two outputs in anitphase and a single offset control it would normally be expected that the same offset would be applied to both outputs and not - as is implemented at present - that one output would have a positive offset and the other a negative offset. The Sine Wave outputs are implemented using the SINE() Source. The offset of a SINE() output voltage is defined by the **DCOFFSET** parameter: The expression to control the offset for both SINE() outputs should be: DCOFFSET = O **The Amplitude of the Sine Wave output is double that of the Rectangular and Triangle Wave outputs.** The AMPLITUDE parameter of the SINE() Source represents the Peak value and not the Peak-to-Peak value. Therefore for the Sine Wave output to give the same Peak-to-Peak swing as the outputs defined by PULSE() Sources, the expression for the SINE() Source Amplitude should be: AMPLITUDE=A/2 For detailed information on SINE() and PULSE() signal sources in LTspice, please study: [https://easyeda.com/editor#mode=sim,id=5e3d25de3492487b88275e38c4620239](https://easyeda.com/editor#mode=sim,id=5e3d25de3492487b88275e38c4620239) and: [https://easyeda.com/editor#mode=sim,id=d49a7278feef4be2b72d851765f3acbb](https://easyeda.com/editor#mode=sim,id=d49a7278feef4be2b72d851765f3acbb) and for more information about sources: [https://docs\.google\.com/document/u/1/d/1OWZVVFRAe\_2NW3WratpkA\_SGuHa5AcRow5ZRfvcoVTU/pub\#h\.bq0i7caw31bh](https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.bq0i7caw31bh)
