FEATURES
Record Length
A long record length and high-speed sampling rates allows
the user to capture and view a more detailed “picture” of
a complex Waveform and it components. Up to 125kB samples
of waveform information may be captured and accurately
displayed on the LCD screen as show in the illustration below.
Math
Dual channel Math functions are available for
adding and subtracting waveforms applied to
the CHA and CHB inputs. The FFT allows you to
view a waveform spectrum using a Rectangular,
Hamming, Hanning or Black Man-Harris window.
