| - | The CH A AWG generator should be configured for a 500 Hz Sine Shape with the Max value set to approximately 2.5 V + VBE and the Min value set to approximately +VBE. AWG channel A should be set to SVMI, Split I/O Mode and the AWG B channels should also be in Split I/O Mode (SVMI or Hi-Z does not matter in this case). The AIN and BIN input pins, are used to measure the voltage at the emitter or the voltage at the collector. To also display the AWG channel A output waveform we can use the X Math trace. From the Curves drop down menu select CA-V, CB-V and X Math traces. Open the Math controls screen and enter AWGAwaveform[t] in the X Math Formula entry. The Units can be V and the X Axis can be V-A. | + | The CH A AWG generator should be configured for a 500 Hz Sine Shape with the Max value set to approximately 2.5 V + VBE and the Min value set to approximately +VBE.

| To measure the input to output gain compare the p-p voltage measurements at the emitter and collector to the AWG A p-p setting (Max – Min). You can also display the differential voltage (DC part cancels) between the two outputs by clicking on the CBV-CAV Built In Expression on the Math controls. | To measure the input to output gain compare the p-p voltage measurements at the emitter and collector to the AWG A p-p setting (Max – Min).
