Using the One Button Measurements to Measure N dB Bandwidth, Percent Amplitude Modulation, and Third Order Intercept (TOI).

The spectrum analyzer includes one-button measurement functions. With one key press they make accurate measurements of:

•N dB Bandwidth

•Percent Amplitude Modulation

•Third Order Inter-modulation

The signal or signals being measured must be displayed before activating the measurement. Measurements are made continuously, updating at the end of each sweep. This allows you to make adjustments and see changes as they happen. The single sweep mode can also be used, providing time to study or record the data. The individual measurements are described below.
