Multi-Domain Analysis with M1 OT™


By combining a real-time oscilloscope with post-processing software, M1 Oscilloscope Tools is able to analyze and display your data in all three measurement domains:


Voltage Domain

M1's ScopeView™ lets users display a Voltage-versus-Time display of all scope analog channels and thereby remain in the M1 user interface to characterize or debug your problems. This greatly reduces switching time between applications. It also exposes a large number of new pulse parameter measurements to be made within M1 or within an M1 TestScript™ so that the user has a more complete physical layer test system. During the debug phase of the design process, the user can add to this integrated ScopeView by locking the X-axis for all TimeViews and use markers in each linked view that move together in unison across all views simultaneously. The ScopeView lets the user view up to 4 analog channels at once. Users can optionally turn on markers, see raw data points or interpolated waveforms, and see the thresholds being used for the timing measurements. Users can also zoom to the region around the minimum value in the acquisition, zoom to the region of the maximum value in the data, or zoom to the region of the trigger reference point (often referred to as time = 0).



Modulation Domain (i.e. Time vs Time)

M1's TimeView™ allows you to view the behavior of your signal in a time-vs-time manner, for example showing the length of each period in a clock train vs its order of arrival. ASA invented this type of analysis using the data from a real-time oscilloscope, and holds several patents on that technology for which we draw patent royalties from scope manufacturers.


Frequency Domain

 The M1 FFTView™ gives users a spectral view of their signals-under-test. The FFTView lets M1 users understand the jitter spectrum of their DUTs. The X-axis is in frequency units, and goes from 0 Hz to 1/2 of the fundamental frequency of the signal being measured. The FFT cannot go above this frequency because the 'sample rate' (for the purposes of the FFT) is equal to the fundamental frequency (the clock frequency for a Clock, or the data rate for a Data signal). In that case, Nyquist tells us that only frequencies up to 1/2 of that frequency can be extracted. The Y axis is in either decibel (dB) units or time units, as selected using the dropdown list. You may select either dB units or three different time units.  The time units are selected according to what amplitude you wish to see - RMS jitter, Peak (1-sided) jitter, or Peak-to-Peak (2-sided) jitter. Various filters and window methods (Hamming, Hanning, etc.) are available.
