4.Advanced User Guidebook Using FFT function The FFT (fast Fourier transform) math function mathematically converts a time-domain waveform into its frequency components. It is very useful for analyzing the input signal on Oscilloscope. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies.
4.Advanced User Guidebook Best solution for frequency, worst for magnitude. Best type for measuring the frequency spectrum of nonrepetitive signals and measuring frequency components near DC. Recommend to use for: Rectangle Transients or bursts, the signal level before and after the event are nearly equal. Equal-amplitude sine waves with frequencies those are very close. Broadband random noise with a relatively slow varying spectrum. Best solution for magnitude, worst for frequency.
4.Advanced User Guidebook DC component or offset can cause incorrect magnitude values of FFT waveform. To minimize the DC component, choose AC Coupling on the source signal. To reduce random noise and aliased components in repetitive or single-shot events, set the oscilloscope acquisition mode to average. What is Nyquist frequency? The Nyquist frequency is the highest frequency that any real-time digitizing oscilloscope can acquire without aliasing. This frequency is half of the sample rate.
4.Advanced User Guidebook Figure 4-1 Information about Vertical Scale How to Set the Horizontal System The HORIZONTAL CONTROLS includes the Horizontal HOR button and such knobs as Horizontal Position and Horizontal Scale. 1. Horizontal Position knob: this knob is used to adjust the horizontal positions of all channels (include those obtained from the mathematical manipulation), the analytic resolution of which changes with the time base. 2.
4.Advanced User Guidebook How to Set the Trigger/Decoding System Trigger determines when DSO starts to acquire data and display waveform. Once trigger is set correctly, it can convert the unstable display to meaningful waveform. When DSO starts to acquire data, it will collect enough data to draw waveform on left of trigger point. DSO continues to acquire data while waiting for trigger condition to occur.
4.Advanced User Guidebook falling speed. Runt Trigger: Trigger pulses that pass through one trigger level but fail to pass through the other trigger level.
