    Math Waveforms FFT Measurement FFT is used to compute the fast Fourier transform using analog input channels or an arithmetic operation g(t). FFT takes the digitized time record of the specified source and transforms it to the frequency domain. When the FFT function is selected, the FFT spectrum is plotted on the oscilloscope display as magnitude in dBV versus frequency.

If you do manually set scale or offset, turning the horizontal scale knob will not change the span or center frequency settings, allowing you see better detail around a specific frequency.

When the FFT source is channel 1 or channel 2 (or channel 3 or 4 on 4-channel models), FFT units will be displayed in dBV when channel units is set to Volts and channel impedance is set to 1 MΩ. FFT units will be displayed in dBm when channel units is set to Volts and channel impedance is set to 50Ω.
  • Page 85 Math Waveforms The following figure illustrates aliasing. This is the spectrum of a 990 Hz square wave, which has many harmonics. The sample rate is set to 100 kSa/s, and the oscilloscope displays the spectrum.

    Acquisition Control Sampling Theory The Nyquist sampling theorem states that for a limited bandwidth (band-limited) signal with maximum frequency f , the equally spaced sampling frequency f must be greater than twice the maximum frequency f , in order to have the signal be uniquely reconstructed without aliasing.
  • Page 180 Acquisition Control At the oscilloscope bandwidth, sampling theory says the required sample rate is f = 2f . However, the theory assumes there are no frequency components above in this case) and it requires a system with an ideal brick-wall frequency response.

  • Page 182: Oscilloscope Bandwidth Required

    Acquisition Control Oscilloscope Bandwidth Required The oscilloscope bandwidth required to accurately measure a signal is primarily determined by the signal's rise time, not the signal's frequency. You can use these steps to calculate the oscilloscope bandwidth required: 1 Determine the fastest edge speeds. You can usually obtain rise time information from published specifications for devices used in your designs.

    UART/RS232 Triggering and Serial Decode UART/RS232 Triggering To set up the oscilloscope to capture UART/RS-232 signals, see "Setup for UART/RS232 Signals" on page 361. To trigger on a UART (Universal Asynchronous Receiver/Transmitter) signal connect the oscilloscope to the Rx and Tx lines and set up a trigger condition. RS232 (Recommended Standard 232) is one example of a UART protocol.
  • Page 364 UART/RS232 Triggering and Serial Decode • Rx 1:Data — For use when the device under test data words are 9 bits in length including the alert bit (the 9th bit). Triggers only when the 9th (alert) bit is 1. The specified data byte applies to the least significant 8 bits (excludes the 9th (alert) bit).

    UART/RS232 Triggering and Serial Decode 6 If the oscilloscope is stopped, press the [Run/Stop] key to acquire and decode data. If the setup does not produce a stable trigger, the UART/RS232 signals may be slow enough NOTE that the oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then press the Mode softkey to set the trigger mode from Auto to Normal.

    UART/RS232 Triggering and Serial Decode • When using the 9 bit format, all data words are displayed in green, including the 9th bit. The 9th bit is displayed on the left. • When a data word value is selected for framing, it is displayed in light blue. When using 9-bit data words, the 9th bit will also be displayed in light blue.

    UART/RS232 Triggering and Serial Decode Interpreting UART/RS232 Lister Data In addition to the standard Time column, the UART/RS232 Lister contains these columns: • Rx — receive data. • Tx — transmit data. • Errors — highlighted in red, Parity Error or Unknown Error. Aliased data is highlighted in pink.
