Cursor measurement
Cursors can be placed on displayed waveforms to display the measured values between the
cursors and waveforms.
Select from the following cursors.
ΔT, ΔV, ΔT & ΔV, Marker, Degree
Automated measurement of
waveform parameters
The following waveform parameters can be automatically measured.
Items that are measured over the entire specified range of data and are irrelevant to the period:
Max, Min, P-P, High, Low, Amplitude, Rms, Mean, Sdev, , IntegTY, +Over,
–Over, Pulse Count, Edge Count
Items that are measured in the first period in the specified range:
Freq, Period, Burst, +Width, –Width, Duty, Rise, Fall, Delay
Items that are measured over all periods in the specified range:
AvgFreq, AvgPeriod
ΔT & ΔV cursor value:
V1, V2, ΔT
For logic signals, the following items are selectable.
Freq, Period, AveFreq, Duty, Pulse Count, Delay
In cycle mode, the following items are valid.
Max, Min, P-P, High, Low, Amplitude, Rms, Mean, Sdev, , IntegTY, +Over,
–Over
The maximum total number of items that can be displayed in Area1 and Area2 on the screen is
30. Area1 indicates the area (the first area) for the normal automated measurement of waveform
parameters. For details on Area2, see “Enhanced parameter measurement” described later.
Statistical processing of
waveform parameters
For the automated measured values of waveform parameters, the following three types of statistical
processing are available.
Continuous: Calculates statistics on normal measurement that is performed multiple times.
Cycle: Calculates statistics on the measurement of each period of the displayed waveform.
History: Calculates statistics on the measurements of multiple history waveforms.
The resultant statistics that are displayed are as follows:
Max, Min, Mean, σ, Count
The maximum total number of items that can be displayed in Area1 and Area2 on the screen is 9.
For details on Area2, see “Enhanced parameter measurement” described later.
Trend display and histogram
display of waveform
parameters
Up to two trends or histograms of the specified measurement items can be displayed.
The maximum total number of items that can be displayed in Area1 and Area2 on the screen is 9.
For details on Area2, see “Enhanced parameter measurement” described later.
Enhanced parameter
measurement
Performs automated measurement of waveform parameters on the second area (Area2).
In addition to the normal waveform measurement range (Area1; desribed earlier), you can
specify another measurement range (Area2). In addition, calculations can be performed using the
automated measurement values of waveform parameters.
The maximum total number of items that can be displayed in Area1 and Area2 on the screen is 30.
Frequency distribution
analysis
Counts the frequency of data occurrence in a specified area and displays the values in a histogram.
You can select whether to count the frequency on the vertical or time axis.
The mean, standard deviation, maximum value, minimum value, peak value, median, etc., can be
measured on the histogram.
You can set up to two histogram source waveforms.
Action-on-trigger
A specific action can be executed when the DLM4000 triggers.
You can set the number of times to execute the action on the basis of the number of waveform
acquisitions or the number of determinations.
Actions: Beeping, screen capture data printing or saving, waveform data saving, mail transmission
GO/NO-GO determination
A specific action can be executed when the GO/NO-GO result is NO-GO.
You can set the number of times to execute the action on the basis of the number of waveform
acquisitions or the number of determinations.
Conditions: Up to 4 can be specified.
Determination logic: Four conditions can be combined using AND or OR logic.
Reference: The source waveform enters the reference range (IN), moves outside the search
range (OUT), or don’t care (X)
Reference range type: Select from the following:
RectZone: Rectangular zone. Cannot be used on FFT waveforms.
WaveZone: Waveform zone. Cannot be used on XY or FFT waveforms.
PolygonZone: Polygonal zone. Cannot be used on FFT waveforms.
Parameter: Zone between the upper and lower limits of one waveform parameter.
Actions: Beeping, screen capture data printing or saving, waveform data saving, mail transmission
