Page 222: Specified Region Shift
EDIT Menu Specified Region Shift The Region Shift... item shifts a user specified region of a waveform in one of the following ways. Right or left Expand (out from the center) Compress (in toward the center) If the specified amount of the shift is less than the sampling interval, the original waveform is resampled using data interpolation to derive the shifted values.
Page 223: Figure 4A 56: Data Shifted Using The "Right" Item
EDIT Menu Shift Type Selection There are four types of specified region shifts. The Type item selects which shift operation will be performed. Right or Left shifts the selected region to the right or left, respectively. Expand moves the data out from the center. Compress moves the data toward the center.
Page 224 EDIT Menu The Shift Values For Selecting Expand or Compress Expand The maximum value that you can specify for a shift is the number of waveform data points. If a section of data is shifted beyond the maximum number of data points, the data contained in that section is lost after the shift.

Interpolation Selecting the interpolation method Data Value Handling of overlapping regions in the shift result Cursor Point Interpolation of the data on the cursors Smooth +/- Points Setting the smoothing width at the data boundary positions Interpolation The data is resampled when shifting by fractional amounts.
Page 226: Figure 4A 59: Quadratic Interpolation
EDIT Menu Quadratic Interpolation Figure 4A 59 provides an example of quadratic interpolation. If point X is shifted to the left by 0.2, the new value is calcu lated by interpolation using three points: the shifted point, the point preced ing the shifted point, and the point following the shifted point.

Page 513: Fft (Fast Fourier Transforms
Appendix D: Miscellaneous FFT is an algorithm for fast calculation of discrete Fourier transform. FFT FFT (Fast Fourier transforms the time axis signal onto the frequency axis. FFT can also pro Transforms) vide the frequency component magnitudes and phases. With the FFT editor, you can use inverse FFT (IFFT) to generate the real time data from the frequency component magnitudes and phases.
Page 514: Relationship Between Phase And Delay
Appendix D: Miscellaneous For the given data length on the time axis, FFT has frequency components from -N/2 to N/2-1. However, when the real number data on the time axis is transformed, FFT gives results symmetrical about 0 Hz (DC). Because of this symmetry, all the necessary frequency data is contained between 0 and N / 2 - 1.
Page 515: Fft Window Functions
Appendix D: Miscellaneous FFT Window Functions FFT calculates with limited data blocks. Also, since FFT calculations assume that the sampled data blocks are repeated infinitely, frequency error arises from non continuities generated at the edges of data blocks. This frequency error is called leakage error.
Page 516: Square Wave Window
Appendix D: Miscellaneous The window functions are effective for investigating the frequency compo nents of the acquired waveform, but the waveform after the window function is applied differs from the original waveform. Square Wave Window The square wave window does not taper the time region data.
Page 517: Hamming Window
Appendix D: Miscellaneous Hamming Window The hamming window is similar to a hanning window, but it suppresses more the transmissivity for the side lobes next to the transmitting bandwidth. Compared to FFT processing using a hanning window, the degree of separation between two frequencies is greater, as can be seen in Figure D 10.
Page 518: Blackman Window
