Signal Wizard 2.5 boasts a high precision, 24-
The first plot shows a spectrum, plotted in dB scale, for a 1 kHz sine wave generated using Signal Wizard. The plot on the far right shows a similar spectrum produced by a standard bench top analogue function generator. Noise harmonics are considerably lower for Signal Wizard. In the table, THD measurements are given for several spot sine wave frequencies (2 kHz, 3 kHz and 5 kHz), for Signal Wizard and the analogue instrument. The statistics confirm that at each frequency, the performance of Signal Wizard using the interpolation method is superior to that of the analogue function generator.
Rather than using a look-
The sine wave generator function is simplicity itself to use. Select the Sine Wave tab from the Hardware Control Panel, select the desired frequency or frequencies using the sliders, and click the button labelled “sine”. The frequencies and gains can be altered in real time. What’s more, the settings can be saved at the click of a mouse so that the hardware module starts up with the saved frequencies and gains as soon as it is powered up, without the need of a computer.
