For example, :MATH:OFFSet2 /*Set vertical offset to 2V*/ :MATH:OFFSet? /*The query returns 2.000000e + 00*/ :MATH:FFT:SOURce For example, :MATH:FFT:SOURce CHANnel1 /*Set the source of FFT operation to CH1*/ :MATH:FFT:SOURce? /*The query returns CHAnel1*/ :MATH:FFT:WINDow For example, :MATH:FFT:WINDow BLACkman /*Set the window function for FFT operation to Blackman*/ :MATH:FFT:WINDow? /*The query returns BLACK*/ :MATH:FFT:SPLit 38 / 136 MathVerticalScale) to (1000 × MathVerticalScale) in steps of MathVerticalScale / 50 Description MathVerticalScale is the vertical scale of the calculation result, which can be set by the: MATH: SCALe command.
Return format The query returns the vertical offset of the current operation result in scientific notation. Command format :MATH:FFT:SOURce :MATH:FFT:SOURce? Function description Set or query the source of FFT operation / filter. Parameter Name Type Range Default Discrete {CHANnel1|CHANnel2|CHANnel3|CHAN nel4} CHANnel1 Return format The query returns CHANnel1, CHANnel2, CHANnel3, or CHANnel4. Command format :MATH:FFT:WINDow :MATH:FFT:WINDow? Function description Sets or queries the window function of the FFT operation.
Parameter Name Type Range Default Discrete {RECTangle|BLACkman|HANNing| HAMMing| FLATtop|TRIangle} RECTangle Description ▷Using the window function can effectively reduce the effect of spectral leakage. ▷Each window function is suitable for measuring different waveforms. You need to choose according to the measured waveform and its characteristics. Return format The query returns RECT, BLAC, HANN, HAMM, FLAT, or TRI. Command format :MATH:FFT:SPLit :MATH:FFT:SPLit? Function description Turn on or off the half-screen display during FFT calculation, or query the status of half-screen display during FFT calculation.
