MEASure Subsystem

Making Measurements

Using Baseband I/Q Inputs (Option B7C)

MEASure Subsystem

Spectrum (Frequency Domain) Measurement This measures the amplitude of your input signal with respect to the frequency. It provides spectrum analysis capability using FFT (fast Fourier transform) measurement techniques. You must select the appropriate mode using INSTrument:SELect, to use these commands.

Waveform (Time Domain) Measurement This measures the power in your input signal with respect to time and is equivalent to zero-span operation in a traditional spectrum analyzer. You must select the appropriate mode using INSTrument:SELect, to use these commands.
