File Menu

The File Menu provides a means to print plotted data, as well as open and save data files.

Open Data File … (.thd or .dsc)

Used to locate and open saved files. ZonicBook uses files with .thd extensions. View applications, i.e., WaveView, DaqView, Personal DaqView, LogView, and ChartView use files with .dsc extensions.

Save Plot Setup (PSET) …

These two menu items provide a means of saving [or opening] function files. Time and auto-spectrum data is saved. If there is any reference channel cross-spectrum is saved for all channel pairs. The file extension is .mds.

Recall Plot Setup (PSET) …

These two menu items provide a means of saving [or recalling] the current plot condition, such as window locations and window content, including: channel numbers, function type, axis-type, and range. These files can be recalled at a later date to process customized plot conditions.

Without user intervention, the plot setup file is automatically saved with .mds, .dsc, and .thd files.

You can have plot setups automatically recalled whenever you recall data files. To select this option, open the Preferences window [accessed through the Edit pull-down menu] and check the box labeled “Recall Plot Setup When Recall Data Files.”

An Introduction to eZ-Analyst Series Software 2

A Screen Capture from eZ-Analyst in Playback Mode

While the focus of this document is on eZ-Analyst, it can also be used for eZ-TimeView, and eZ-FrequencyView. Those two post-acquisition analysis applications were derived from

the more powerful eZ-Analyst program. It should be noted that the eZ-Analyst program is only compatible with WaveBooks,

ZonicBook/618E, and ZonicBook Medallion series devices. However, the related “view” applications can be used with many other devices, for example, DaqBooks, DaqBoards, LogBooks, ChartScans, and Personal Daqs.

Features of the view applications vary from one application to another, and are listed in the comparative table on the following page. Although the table includes a column for eZ-PostView, this document is not to be used as a reference for that application. eZ-PostView is discussed in a separate document, the eZ-PostView User’s Guide, p/n 1086-0926.

The “view” applications are integrated with the primary data acquisition software, including DaqView, Personal DaqView, ChartView, LogView, and WaveView. The eZ-PostView application provides easy-to-use post-acquisition analysis capability, and is included free of charge as a part of product support. The other two view programs (eZ-TimeView and eZ- FrequencyView) have additional features and are available for purchase. These more versatile “view” applications are initially accessed via an authorization-code. Note that the code is only required to “unlock” the application for its first run and is not required for subsequent startups.

The following table compares the “view” applications to the eZ-Analyst program, from which they were derived.

2) eZ-Analyst and eZ-FrequencyView - each offers the following Complex Function Display Types: Magnitude, Phase, Real, Imaginary, Nyquist, Magnitude and Phase, and Real and Imaginary.

3) eZ-Analyst and eZ-FrequencyView - each offers the following Function Display Types: Spectrum, Auto-Sp ectr um, PSD (Power Spectral Function), Strip Chart (Time).

4) eZ-Analyst and eZ-FrequencyView – each offers the following Response Channel FFT Windows: Hanning, Flat Top,

Exponential, and Blackman-Harris.

The eZ-Analyst Series “view” programs make use of eZ-Analyst’s Playback Mode and, therefore, do not require the presence of physical hardware. In fact, when eZ-Analyst is in Playback Mode, it is functioning in the exact manner as eZ-FrequencyView. In other words, when in PlayBack Mode, eZ-Analyst is strictly a post-acquisition display and analysis program.

Raw time-domain data, that has been recorded-to-disk, can be played back for analysis repeatedly. For example, a raw signal could be played back several times, each time using a different filtering algorithm to manipulate the original signal. Once the desired results have been achieved the new data can be exported in a new format and to a different file. The original file can remain unchanged, and kept for future analysis.

How this Manual Relates to the “View” Applications

This manual was original written as a reference guide for users of eZ-Analyst. This was prior to the development of the “view” applications. However, since the post-acquisition “view” programs were derived directly from eZ-Analyst, it is easy to apply the appropriate sections of the manual to your specific “view” application, i.e., to eZ-TimeView and to eZ-FrequencyView.

Note: WaveBook user’s who want to have post-data analysis view capabilities accessible from

WaveView’s <View Data> button will need to install one of the “view” applications, i.e., eZ-PostView, eZ-TimeView, or eZ-FrequencyView. The latter two applications are available for purchase. The eZ-PostView application is free.

eZ-FrequencyView

When you are using eZ-FrequencyView, you are essentially running eZ-Analyst in its Playback Mode. The table on page 2-2 indicates the applicable features. You can not record data from

eZ-FrequencyView. eZ-FrequencyView is supported by the primary data acquisition programs, for example, DaqView,

LogView, and WaveView. It can be accessed through the primary application’s View Data button, or

accessed independently from your program files directory (where you installed your software). The first time you run eZ-FrequencyView, you will need to enter an authorization code. The code is

supplied when the package is purchased.

eZ-TimeView

When you are using eZ-TimeView, you are essentially running eZ-Analyst in its Playback Mode, minus several analysis features that are available in eZ-FrequencyView and eZ-Analyst. For example, when using eZ-TimeView there are no Transfer Function Display Types, Complex Function Display Types, or FFT Windows available. However, the application does provide calculation options pertaining to peakto-peak, mean, RMS, and does allow for data zooming. Refer to the table on page 2-2 for a complete list of the applicable features. Note that you can not record data from eZ-TimeView.

eZ-TimeView is supported by the primary data acquisition programs, for example, DaqView, LogView, and WaveView. It can be accessed through the primary application’s View Data button, or accessed independently from your program files directory (where you installed your software).

The first time you run eZ-TimeView, you will need to enter an authorization code. The code is supplied when the package is purchased.

eZ-PostView provides simple “time-domain” viewing. From this application you can display up to 8 time-domain function windows and display up to 16 channel traces per window. Data is automatically scaled to optimize its fit in the window. Window, channel trace, and cursor colors can be customized.

eZ-PostView is a free “view” program. The application has no Transfer Function Display Types, Complex Function Display Types, or FFT Windows available. Refer to the table on page 2-2 for a complete list of the applicable features. Note that you can not record data from eZ-PostView.

eZ-PostView is supported by the primary data acquisition programs, for example, DaqView, LogView, and WaveView. It can be accessed through the primary application’s View Data button, or accessed independently from your program files directory (where you installed your software).

You do not need to enter an authorization code to run eZ-PostView.

Reference Note: If you are only making use of eZ-PostView you should refer to the eZ-PostView User’s Guide, p/n 1086-0926. A PDF version of that document is installed onto your harddrive (in the Program Group by default) as a part of product support.

Note that PDF versions of documents can be read directly from the installation CD.

A Look at eZ-Analyst

eZ-Analyst can only be installed as software support for ZonicBook

Medallion, ZonicBook/618E, and WaveBook devices. If your system is making use of another type of data acquisition device you cannot install eZ-Analyst. However, you can still install one of the “view” applications, i.e., eZ-PostView, eZ-TimeView, or eZ-FrequencyView.

eZ-Analyst is a graphical analysis application that can be used to collect, analyze, record, and play back recorded data. Using ZonicBook or WaveBook hardware systems, ez-Analyst can collect and display multiple channels of data in real-time. The graphical displays can consist not only of the raw time-domain data, but also plots of frequency domain data. For example, real time FFT (Fast Fourier Transform) plots.

Data that is recorded to disk-file is in the raw time domain and can be played back for additional analysis time and time again. For example, a raw signal can be played back overand-over using different filtering algorithms to manipulate the signal. Once the desired results have been achieved, the new data can be exported to a different file and format, while preserving the original file. In addition, the playback capability does not require the presence of a ZonicBook or WaveBook system.

eZ-Analyst Series 979595 Introduction 2-5

You can select the Measurement Mode or the Playback mode from either the Task pull-down menu, or by using the <Change Task Mode> button [the first button in the Task Bar]. The Task Tool Bar automatically changes to accommodate the selected mode.

Measurement Mode

The Measurement Mode is an active data-collecting mode, which, for that reason, requires the use of data acquisition hardware. The Measurement Mode can only be selected if a ZonicBook or WaveBook is available.

The Measurement Mode acquires data using one of the following three methods: (1) Scope- Continuous, (2) Scope-Single, and (3) Record.

The Scope-Continuous and Scope-Single methods display data, but do not log data. The scope methods are useful for signal validation and checkout. The Record method, in addition to displaying data, logs data-to-disk based on user-defined start and stop criteria.

In addition to being selected from the Task Menu, the Measurement Mode can be selected from the Task Tool Bar by clicking the <Change Task Mode> button while in the Playback Mode. Clicking this button from Measurement Mode will change the task mode tool bar to Playback.

Output Channel Setup, in chapter 4.

An active cursor lock button will have the image of an opened or locked padlock. When the padlock is locked (closed), cursors in multiple windows will be synchronized and locked, providing that the windows are of the same time domain, frequency domain, or have the same octave band data.

An opened padlock image indicates that cursors in multiple windows have independent cursor movement, i.e., they are unsynchronized.

Export

This button exports data, if export conditions are set. For details, see th e section, Export Menu> Function Data Set(s), in chapter 3.

eZ-Analyst Series 979595 Introduction 2-7

Playback Mode

The Playback Mode does not require the presence of physical hardware. When in Playback, eZ-Analyst is strictly a post-acquisition display and analysis program. Raw time-domain data, that has been recorded-to-disk, can be played back for analysis repeatedly. For example, a raw signal could be played back several times, each time using a different filtering algorithm to manipulate the original signal. Once the desired results have been achieved the new data can be exported in a new format and to a different file. The original file can remain unchanged, and kept for future analysis.

To activate the Playback Mode, select Playback/Review on the Task Menu. An option is to click the <Change Task Mode> button (the first button in the tool bar) while in the Measurement Mode. If a WaveBook or ZonicBook is not available eZ-Analyst will automatically enter the Playback mode and will display the data that was most recently recorded to disk.

A Word About Configuration

Playback Mode Task Bar

Configuring Input Channels

eZ-Analyst makes use of various menus and related windows for the purpose of configuration. Chapter 4 is devoted exclusively to the Edit menu. It is that menu which provides access to the Configuration Window (see figure). It is from that Configuration Window that the majority of acquisition related settings are made. Other menus are discussed in the following chapter.

Foreword

In addition to use as a reference for eZ-Analyst, this chapter can also be used for eZ-TimeView, and eZ-FrequencyView. However, there are many cases where a menu or

window does not apply to one or more of these “view” applications. In these instances, functions or selection options that can not be used will be either “grayed-out” or hidden in the actual application. The table on page 2-2 can be used as a quick reference as to what features apply to a particular application.

The menus, with exception of the Task Menu and the Edit Menu, are presented in the order that they appear on eZ-Analyst’s main window. The Task Menu is discussed first since it is from this menu that the user (1) selects Measurement Mode or Playback Mode and (2) makes use of the Auto-Ranging feature for input channels.

The Edit Menu is perhaps the most significant of all eZ-Analyst menus. It is used frequently and has roughly 40 pages of support documentation. For this reason the Edit Menu is discussed in a separate chapter.

Reference Note: Refer to chapter 4 for information regarding the Edit Menu.

Note that the “view” programs have no Task Menu. This is because they actually have only one task, “Playback Mode.”

Notes:

¾ eZ-Analyst only applies to ZonicBook Medallions, ZonicBook/618E, and WaveBook devices. ¾ LogBooks, DaqBoards, DaqBooks, ChartScans, etc., can use a “view” application such as

eZ-TimeView, eZ-FrequencyView, or eZ-PostView.

¾ The operational differences between the use of eZ-Analyst in ZonicBook Medallion,

ZonicBook/618E, and WaveBook are minor. The differences are noted when of importance to the user.

Task Menu > Input Range (Auto/Manual) *

Auto-ranging is a procedure that automatically sets the input full-scale voltage (FSV) range for input channels. The FSV is set by measuring a representative sample of real-time data. Autoranging is only performed on active channels.

WaveBook and ZonicBook/618E Applications

Auto-ranging works best if you supply the maximum expected voltage range for the data that will be captured during the acquisition. Therefore, make the Auto Range Duration long enough to apply a typical signal. The maximum duration is 65535 mSecond. Also, make sure that the Auto Range Analysis Frequency is fast enough to capture the high frequency component. Typically the Analysis Frequency will be the same setting as eZ-Analyst’s Acquisition Analysis Frequency.

Note that the AutoRange Dialog Box for ZonicBook/618E looks similar.

* You can access the dialog box for WaveBook and ZonicBook/618E by clicking the <Auto Range>

%, FSVF, & Factors Display

Maximum FSV is the high-end limit for the input voltage.

Note that 25.7 V is the highest possible FSV for a ZonicBook Medallion.

Minimum FSV is the low-end limit for the input voltage. In the figure at the right Minimum FSV is set to 0.2 volts.

HI Accept % defines the highest acceptable percentage of peak input voltage for the selected FSV, i.e., Current, Minimum, or Maximum. Thus, if our selected FSV was 0.2 V and we had an upper limit of 90%; then our upper limit in volts would be 0.18 V. An example follows as to how exceeding this value causes a range adjustment.

LO Accept % defines the lowest acceptable percentage of peak input voltage for the selected FSV, i.e., (Current, Minimum, or Maximum). Thus, if our selected FSV was 0.2 V and we had a lower limit of 10%; then our actual low limit in volts would be .02 V.

Incr Factor (Increasing Factor) is the factor by which the Current FSV will increase, should the peak exceed the upper limit. In the figure we see that the Increasing factor is

1.5. Decr Factor (Decreasing Factor) is the factor by which the Current FSV will decrease,

should the peak not reach the lower limit. Keeping the decrease factor at “1” will result in no decrease of the Current FSV. Setting the Decrease Factor to 0.8 would cause the Current FSV to decrease to 80% of its value if the peak fell short of the low limit.

Note: These are the same values that were entered in the Vpeak column in the Channel Setup

window. The values are immediately replaced when the Auto ranging process begins.

An Example of Auto-Ranging

Maximum FSV set at 25.7 V Minimum FSV set at 0.2 V Upper Limit set at 90% Lower Limit set at 10% Increasing Factor set at 1.5 Decreasing Factor set at 1

In the first iteration we see that we have a peak of 0.19 V. This falls outside of our band of

0.02 to 0.18 V that was established by our upper and lower limit percentages; i.e., 90% of the Current FSV and 10% of the FSV.

As a result, the Current FSV is increased by a factor of 1.5 (our Increasing Factor) and the Current FSV becomes 0.30 V. Our limits, in volts, also changed since we are now looking at percentages of 0.30 volts instead of the same percentages of 0.20 volts.

In the second iteration of our example, we see a 0.22 volt peak. This value is within our established limits so the Current FSV does not change.

Note 1: If the Capture Mode is the Input Channel (Trigger Mode), the Auto Range process waits for a

trigger.

Note 2: A Start FSV of Minimum or Maximum can selected instead of Current FSV, as in our example.

Minimum FSV is the default.

In this example we have set the radio button for Current FSV instead of Minimum or Maximum (note 2). The starting value, in the example, is 0.20 V.

Task Menu > Calibration

When calibration is performed, a signal of known Peak level [or RMS value] is supplied to a transducer that is connected to an active input channel. An accelerometer calibrator or piston phone is typically used to generate the calibration signal for vibration sensors and microphones, respectively.

eZ-Analyst includes a Calibration window for selecting the channels to be calibrated and for entering several signal-related parameters. In addition, the calibration is actually started from the window.

When you are in “Measurement Mode” you can access the Calibration window from the Task Menu or from the Input/Output Channels tab.

Examples: Accelerometer calibrators typically make use of linear engineering

units and, as their name implies, are used for calibrating accelerometers.

Piston phones are most often used for calibrating microphones. Piston phones typically make use of decibel (dB) engineering units.

Calibration Display Screen

¾ When a channel is calibrated, the number of averages used will be 5, or

the number that is designated in the “No. of Averages” field (located on the Analyzer Tab). The greater of the two values will be used, automatically.

¾ When a channel is calibrated, the blocksize of the acquisition will

automatically be 4096, or the blocksize value that is stated on the Analyzer Tab, providing it is 4096 or higher.

A discussion of the various regions of the Calibration window now follows. The section concludes with an example.

No. This column displays channel numbers [1, 2, 3, … etc.] for easy

reference to their associated cells. The channel numbers, being for display indication only, are fixed and can not be edited.

Active When “Single Channel” is selected, you can click on a radio button

in the “Active” column to enable one channel for calibration. When the calibration is complete, select the radio button for the next channel to be calibrated.

When “Multiple Channel” is selected, the radio buttons are replaced by checkboxes. Ensure that each channel to be calibrated has the associated box checked, and that the remaining channels remain unchecked. For multiple channel applications note that you can click on the column label, i.e., the word “Active” to simultaneously check or uncheck all channel checkboxes in the column.

Note: The channel settings in the Calibration window are

independent of the selections that appear in the Input Channel Setup window. Only active channel shows up at calibration window.

Calibration Procedure, an Example

Accelerometer type - Piezotronics 303A03 Calibrator - Piezotronics 394B05 - 1.02 G (RMS) at 80Hz Unit of acceleration - in/sec^2

Note: 1.02 G RMS is equivalent to 393.811 in/sec^2 (1G=386.089in/sec^2).

This is a linear scale, thus we will be selecting Lin in the Calibrator Scale column.

In this example we will be calibrating channel 1.

1. Attach the accelerometer to the calibrator (signal source). Connect the other end of the accelerometer cable to the channel 1.

2. Set the FSV into a proper range (i.e. 32.4 mV) in the Input Channels Setup window, then click the <Apply> button.

3. Set the desired blocksize in the Analyzer Tab if a block size of greater than 4096 is desired.

4. Set the “No. of Averages” in the Analyzer Tab if an average count of greater than 5 is desired.

5. Open the Calibration Window from the Task Menu, or from the Input/Output Channels Tab.

6. Select “Single Channel.”

7. Select “Auto Range,” if desired.

8. Select a Calibration domain. In this case, either “Time” or “Frequency” can be selected.

9. Enter 80 Hz in the Calibrator Frequency field.

10. Ensure the radio button for Channel 1 is enabled (in the Active column.)

11. Select RMS for the Calibrator Type.

12. Select Linear in the Calibrator Scale field.

13. Leave EU dB Reference set at 1.000. Note that this step can be skipped when linear scale is used.

14. Set Calibrator EU at 1.02 ; implying an engineering unit of 1G.

15. Enter 393.811 in the Transducer mv/EU field.

16. Leave the EU Offset at 0.0000. We are assuming no offset in this example. Leave 1.000 as the Transducer Gain. No amplifier or attenuator is being used in our

The Measurement Status Panel only applies to eZ-Analyst. The panel provides basic, but

important information, including trigger and processing conditions, and reference and response coordinates. Status Areas of the panel are as follows:

[A] – Averaging Status. Displays the number of measurements completed followed by the total

number of measurements. For example, “1/6” indicates that 1 of 6 measurements has been completed.

[B] – Trigger/Processing Status. Displays the following:

T – Triggered W- Waiting for Trigger S – Saved the data C – Completed measurement O – Overload rejected D (with yellow background) – Double Hammer Rejected

[C] – First Response Coordinate. Shows the channel number and the modal location. (Note 1) [D] – First Reference Coordinate. Shows the channel number and the modal location. (Note 1)

Note 1: A Response or a Reference Coordinate with a yellow background indicates that the

field is used for the “increasing” method. For example, the Response Field (figure, item “C”) with a yellow background means that the response increase method is being used. This is discussed in the FFT Setup Tab section of chapter 4.

Note 2: Measurement Status indicators are disabled when recording.

The large size of the status areas allows the user to see the measurement status from a relatively long distance, i.e., as compared to the very limited viewing range offered by standard-sized GUI text display fields.

A Note Regarding Frequency Resolution

This note pertains to frequency resolution and is related to the values seen in the Analyzer Tab’s Acquisiton Panel (next two figures). The frequency resolution is related to the Analysis Frequency (bandwidth), Blocksize (the number of data points in one block of data), and the Nyquist factor (a user-selected variable). The following equations apply.

w = b / 2.56f

Where:

w = Frame Width b = Blocksize

2.56 is one of 3 selectable Nyquist Factors. The other two are: 5.12 and 10.24 f = Analysis Frequency

Delta X (Frequency) = 1/w

Where:

Delta X (Frequency) is the frequency resolution w = Frame Width

With these equations we can see how the Frame Width and Delta X (Frequency) are calculated.

With other factors unchanged . . .

¾ Increasing Blocksize increases Frequency Resolution. ¾ Increasing Analysis Frequency decreases Frequency

Resolution.

¾ Increasing the Nyquist Factor decreases Frequency

Resolution.

The lower the “Delta X” frequency, the higher the Frequency Resolution. Thus, a Delta X (Freq.) of 6.25

Hz indicates a higher frequency resolution than does a Delta X (Freq.) of 100 Hz.

Example 1 (see figure)

2.56 is being used for the value of the variable.

Given: Analysis Frequency 5000 Hz Blocksize 2048

w = b / 2.56f = 2048 / (2.56)(5000) = 0.16 seconds

Delta X (Freq) = 1/w = 1 / 0.16

= 6.25 Hz

Note: A Delta X (Freq.) of 6.25 Hz indicates a higher frequency resolution than a Delta X (Freq.) of 100 Hz.

The values shown pertain to example 1.

Acquisition Panel on

the Analyzer Tab

Example 2 (no figure)

2.56 is being used for the value of the variable.

Given: Analysis Frequency 5000 Hz Blocksize 128

w = b / 2.56f = 128 / (2.56)(5000) = 0.01 seconds

Delta X (Freq) = 1/w = 1 / 0.01

= 100 Hz

Higher frequency resolutions indicate that the signal trace will be based on more data points for a given time frame. The higher the frequency resolution, the smoother the trace will be.

Edit Menu

The Analyzer Tab consists of four panels:

Acquisition Filters Trigger Averaging

Analyzer Tab

Edit Menu > Configuration > Analyzer Tab: Acquisiti on Panel

The Acquisition Panel provides a means of setting Analysis Frequency and Blocksize. A note regarding the relationship of Analysis Frequency and Blocksize, to Frame Width and Delta X, is located on the preceding page.

Analysis Frequency: This section of the Acquisition Panel is used to set the maximum bandwidth for analysis. Frequency components above the Analysis Frequency setting will result in aliasing errors in the data. The bandwidth measurement can be set for Hertz (Hz) or Cycles Per Minute (CPM) by use of radio buttons. Note that the processing time for a selected blocksize is fixed by CPU speed.

Increasing the analysis frequency results in:

(a) the hardware streaming packets of data more frequently to the software (b) a greater demand placed on the software to process the data blocks, and (c) less time between data blocks available for task performance.

Blocksize: This section of the Acquisition Panel is used to set the number of data points in a frame or block of data. Acceptable blocksizes range from 128 to 16384 data points.

Blocksize can be viewed as chunks, or packets of data, that move through eZ-Analyst’s software algorithms. As blocksize increases, the amount of data increases, the time required to acquire a block of data increases, and the amount of space required to save the data increases.

Nyquist Factor: A user-selected factor, for which waveform frequency is multiplied by, to ensure that a sampled analog signal is accurately reconstructed. eZ-Analyst has three selectable Nyquist Factors: 2.56, 5.12, and 10.24. The 2.56 Nyquist Factor should be used in most cases as it is the most efficient in FFT Analysis. However, if you suspect signal aliasing, a Nyquist factor of 5.12 or 10.24 should be selected. Higher Nyquist Factors result in more time data in the FFT Analysis. Note that the maximum available Analysis Frequency is reduced for higher Nyquist Factors.

Effects of Changing Analysis Frequency, Blocksize, or Nyquist Factor

The effects indicated by the these two tables pertain to changing the Analysis Frequency while the Blocksize and Nyquist Factor remain unchanged, and visa versa. If the Analysis Frequency, Blocksize, and/or Nyquist Factor are changed [for the same acquisition], then the effect on the other variables can differ, depending on the magnitude and direction of change of those variables.

To capture transient data, go to the Configuration dialog found under the Edit menu and on the Analyzer tab select Input Channel and specify the applicable channel and conditions.

Trigger-related items [in the Analyzer Tab or Recording Setup Tab] being locked-out indicates that the current mode is for playback operation. If so, perform the following:

(1) close the Configuration Window (2) select “Measurement Mode” from the Task pull-down menu (3) open the Configuration window

Capturing Transient Data

Setting eZ-Analyst to trigger on an Input Channel captures transient data when the associated parameters are correctly specified. The following sections discuss the associate parameter and how they apply to a signal such as an impact hammer striking an object. The signal show is from an accelerometer located in the hammer’s head.

Set Trigger level:

The first and most important parameter is the trigger level. This parameter specifies the level in which the signal must pass through in order for an acquisition process to begin. An ideal level will assure that the signal is well above any noise or erroneous movement that will cause a trigger. An ideal level will also assure that the level is not above the maximum output of the signal source. Violating these ideal conditions can result in either a premature trigger or no triggering at all. For example, if a signal has a noise floor of 0.5 volts and the trigger level is set to 0.2 volts the acquisition will always trigger for obvious reasons. Conversely, if the maximum signal output is 5.0 volts and the trigger is set to 5.5 volts the acquisition will never trigger.

eZ-Analyst 969795 Edit Menu 4-7

Shifting a Waveform with Pre-Trigger and Trigger Delay

(A) Setting Signal Position

Once an acceptable trigger level has been ascertained, positioning the signal within a block of sampled data (and in the display window) is the next consideration. Often it is necessary to capture the events that lead up to the trigger point. If this is the situation then positioning should be set for Pre-trigger capturing. On the other hand, if the signal of interest occurs after the trigger point, then positioning should be set for Trigger-Delay capturing.

(B) Normal Trigger

Normal Triggering is obtained by specifying zero for the Pre-Trigger and zero for the Trigger Delay; where the trigger point occurs at the first sample point as pictured in the figure to the left.

To capture information before the trigger point, select Pre-Trigger and specify a percentage of the blocksize (see note). For example, if the blocksize was set at 1024 samples, then setting the Pre-Trigger to 10% would result in capturing 102 sample points that exist prior to the trigger point. This has the effect of shifting the waveform to the right as pictured in the figure.

(D) Trigger Delay

Trigger Delay is the opposite of PreTrigger. The Delay causes eZ-Analyst to wait “n%” samples before it begins filling a block of data. This has the effect of shifting the signal to the left.

Note: For ZonicBook Medallion applications, the trigger level is specified in percentage

of full-scale voltage (FSV). For WaveBook and ZonicBook/618E applications, the trigger level is an absolute signal level that must be within the physical input range (within the FSV).

averaging will be applied to a spectral date.

¾ Averaging can be used to decrease the noise in a measurement.

Averaging Panel of Analyzer Tab (2 Views)

A brief description of averaging types and other panel terms now follows. Linear (+): All blocks of data are treated equally in terms of their effect on the averaged

result. Exponential: Similar to linear averaging, Exponential requires a weighting factor that either

increases or decreases the effect of each new data block on the resultant average. Weighting Factor: The Weighting Factor either increases or decreases the effect of each

new data block on the resultant average when Exponential Averaging is used.

New Average = ((New Data) * A.W.F.) + (Old Average * (1-A.W.F))

Peak Hold: The resultant block of data is a collection of points that represent the peak

amplitude for each point in the block. With each new block of data, the current data is compared with the new data on a point by point basis. The highest amplitude for each point in the block is retained.

Linear (-): Also known as Negative Averaging; Linear (-) Averaging is a technique used to identify the natural frequencies of in-service machines that cannot be shut down for analysis. Linear (-) Averaging is a two step process. First, a reference average is acquired. Second, a normal linear average is acquired for each frame. The running average is subtracted from the reference average and the result is displayed. The first time you attempt to start data acquisition after you select Linear (-) averaging, the Negative Averaging Setup/ Measurement window opens. An example of how to perform negative averaging follows these definitions.

eZ-Analyst 969795 Edit Menu 4-9

Time Sync: Time synchronous averaging uses a keyway, or a similar point of reference, as a trigger. The blocksize is set to allow enough time for at least one full revolution. This must be performed in Scope Mode. Channel trigger mode should be used in conjunction with this selection.

Number of Averages: This number specifies the condition for terminating a data acquisition sample. After the number of averages (blocks/frames of data) have been captured and averaged, the eZ-Analyst will automatically stop taking new data. This sample can then be saved. If the number of averages is set to zero, acquisition is continuous and must be halted by the user.

Continuous Measurement: Checking this option restarts the averaging process without user intervention. Note that the data itself is not continuous between measurements. This option is not meaningful for non-averaging operations.

Reference Notes: The following sections of this document contain information that closely relates to the subject of Averaging. Reading over the following material should improve your understanding of the important concepts involved.

4. Start Scope Measurement. Select “Use Current Spectrum as Reference.” Note that the Displayed Spectrum is a Negative Averaged Spectrum. The running

Spectra is subtracted from the Impact + Running, and you are left with the Impact vibration.

In regard to the following three screen shots, the first shows the impact spectra on the non- running motor; the second shows the impact spectra on a running motor; and the third shows the Negative Average spectra. If you compare the Negative Average spectra to the nonrunning impact you will notice that the Running Speed vibration has been subtracted out, leaving Resonances.

Main unit channels, i.e., those that connect directly to a WaveBook or ZonicBook/618E [as opposed to an expansion module] are denoted by the label, “Direct”. Channel Type cannot be edited.

Volts. A constant 4mA bias current is available for ICP transducers that are used as

signal input for ZonicBook/618E’s analog channels (CH1 through CH8) and for compatible expansion modules that accept ICP transducers, for example, the WBK18. The bias current is sourced through the center conductor of the input channel BNC connector and returns to the acquisition device [e.g., ZonicBook/618E or the WBK18] via the BNC’s outer conductor.

The current source features an operating compliance of 24V and is protected in regard to both short-circuit and overvoltage. Operating compliance refers to the highest voltage that can be applied without change of the current source value. In the absence of a transducer, the current source will output an open circuit voltage of 30V. For applications that do not require bias, the current source can be disconnected from the input by un-checking ICP in the Input Channels tab on a per-channel basis.

When the ICP cell is checked for a channel, the current source is enabled, the input voltage is continuously monitored with level detection circuitry. Recognition of a voltage greater than 25V (transducer open) or less than 1V (transducer short) triggers a transducer fault condition for the affected channel. This error is communicated to the user via a front panel LED and is also available through a software status request at the end of an acquisition. When recognized, an error is latched until the commencement of a new acquisition. Consequently, even intermittent faults are detected and communicated. Detection of a fault does not, however, alter the acquisition process or its data.

When the ICP function is not available to a channel a dash appears in the ICP column for the associated channel.

Channels tab. Coupling is available for analog channels (CH1 through CH8) and for compatible expansion channels [e.g., from a WBK18]. AC Coupling can be set to a high pass filter value of 0.1 Hz or 1 Hz. The value is selected in the Edit Menu’s Analyzer Tab (see page 4-5). Note that when DC Coupling is selected the high pass filter is bypassed.

When the Coupling function is not available to a channel, or not used by a channel, a dash appears in that channel’s Coupling column.

EU Mode E(ngineering) U(nits): Select EU or Volt.

Reference Note: Gain and offset adjustments are made from the Calibration

window. You can access the Calibration window from the Task Menu when in Measurement Mode, or from the Input Channels tab. The following parameters apply:

• mV/EU to set the scaling factor of millivolts to Engineering Units.

• EU Offset to set the offset factor that is to be applied to the Engineering

Units.

• dB EU Ref: is applied to displayed data when the Y-axis scale is set to

dB. This is valid only for frequency domain data.

Units Enter the measurement units you will be using. Location

Input Type

This is a simple numbering system. The channel number is the default value for location. However, you can highlight a cell and type a different location number. When you press the Enter key, the value is accepted.

This is the axial direction of the transducer connected to the channel. Make your selection on the popup menu that appears after clicking in the applicable cell.

This is the type of instrument attached to the channel. Menu selections include: Acceleration, Velocity, Displacement, Force, Pressure, Stress, Strain, General, and Tach (Tachometer).

Input Type refers to the Analog Input channel type for CH1 through CH8.

Note: Tachometer properties for the eight Analog Input

channels (CH1 through CH8) are set in the FFT Setup tab. Refer to that section of the document for additional information.

ZonicBook/618E users - do not confuse an analog input channel (CH1 through CH8) with a TACH Channel input (T1, T2, T3, or T4). The later is discussed in the following section.

Configuring Tach Channels (T1, T2, T3, and T4)

Tachometer Section of the Input Channels Tab*

No. This column lists the available Tach channels, e.g., T1, T2. Do not confuse these

channels with analog input channels which can also be used for tachometer input.

Active Available Tach channels are initially active. To set unused channels to OFF,

remove the check from the associated “Active” checkbox.

Label This should be a meaningful name. Highlight a cell before typing a label. When

you press the <Enter> key, the <Apply> button, or the <OK> button the label is accepted.

Ref / Resp There are two types of channels, Reference and Response. All channels are

initialized as Response channels. If you are using a force channel, then (1) highlight that channel’s Response/Reference cell, and (2) select Reference on the resulting popup menu.

Coupling Used to select AC or DC Coupling. For tachometer applications AC Coupling is

almost always preferred. DC Coupling is available to allow viewing of the DC signal, but is of no practical use to tachometer related triggers.

Tach Mode

Used to select one of three available modes: Voltage, Counter, or Period.

Pulse / Rev

Trig Level Trig Slope

RPM Multiplier

Displays the number of pulses per revolution.

Specifies the pulse level that the RPM algorithm considers valid. Specifies whether counting is Positive or Negative. Positive means that the

trigger will be active on rising signal levels. Negative means that the trigger will be active on falling signal levels.

This column is used for entering a value to convert RPM into other units, e.g., Miles per Hour, Revolutions Per Second, or HZ. The desired conversion factor is entered as a multiplier. To divide, enter an appropriate decimal. For example, divide by 2 you would enter a value of 0.5.

Synopsis of Tach Modes

When you connect a tach sensor to a tachometer designated connector, such as the ZonicBook/618E’s TACH BNCs (TACH1, TACH2, TACH3, or TACH4) you can select one of the following three modes: Counter, Period, or Voltage. If you connect a tachometer sensor to a direct Analog Signal Input channel (CH1 through CH8) then the tachometer signal will only be accepted in the Voltage Mode.

If tachometer triggers will occur at a rate greater than or equal to the “scan rate divided by 10” then the Period Mode must be used.

Counter Mode

Use Counter Mode when Pulses per Revolution are needed.

Counter Mode can be used for phase shift observance.

Counter Mode generates a Pulse of Amplitude “+1” for each tach trigger. The counter mode can be used when the number of pulses is less than the scan rate divided by ten (< scan rate / 10).

Once you have established the phase relationship of a machine running near optimum, the observance of phase shifts can be used to signal the development of a mechanical problem.

Period Mode

The period is the time from the rising edge of one pulse to the rising edge of the next pulse, or the time from the falling edge of one pulse to the falling edge of the next pulse.

Use Period Mode when multiple pulses are involved, such as from gear teeth.

Period Mode cannot be used for phase shift observance.

The Period Mode is used for Tachometer inputs which exhibit multiple pulses per revolution. The mode provides accurate overall RPM without sacrificing scan rate. Phase measurements are not possible when using period mode.

Note: 60 seconds divided by the period [in seconds]

equals RPM.

Voltage Mode

Voltage Mode is used for Tachometer inputs to view actual input voltages from the Tach Sensor. Voltage mode is useful for locating an ideal Tach Trigger Voltage setting. An ideal trigger voltage is one that is in a clean region of a leading edge. Note that Voltage Mode cannot be used for Phase measurements between Analog Inputs and Tachometer Inputs.

Use Voltage Mode when you need to determine a trigger voltage.

If you connect a tachometer sensor to one of the 8 Analog Signal Input channels (CH1 through CH8) instead of a TACH channel, then the tachometer signal will only be accepted in the Voltage Mode.

Edit Menu > Configuration > Block Rejection Tab eZ-Analyst Only

The Block Rejection Tab exists to allow the software (or user) to reject blocks of data that result from hammer double strikes, overloads, or simply because the data block “doesn’t look right.” There are three block rejection modes: Double Hammer protects measurements against double hammering. Overload protects the measurement by automatically rejecting overloaded data, and Manual allows you to inspect a measurement and optionally reject it. You can select any or all of the rejection modes. Also see: Considerations Regarding Double

Hammer Rejection, page 4-23.

Note: The Block Rejection panel is only active when in “Measurement Mode.”

When in “Playback” mode the panel fields will be grayed-out.

Block Rejection Tab

Block rejection looks at the acceptable parameters for a block, and rejects blocks that do not meet those parameters.

At the end of each average, if you want to reject that measurement, click on the <Reject?> button. eZ-Analyst will then reject the current frame of data. The data and average counter will go back to the previous measurement. Click in the Manual box to turn the Manual option ON or OFF. When the box is checked, the option is ON.

Block Rejection is used in conjunction with Capturing Transient Data (Input Channel triggering) and Averaging. These topics are discussed on pages 4-7 and 4-9, respectively.
