2. Hardware

The information contained in this chapter will help you to understand the
features of your oscilloscope.

2.1. Hardware description

The M570 series of dual channel digital storage USB oscilloscopes connect to
the computer via USB. They are compatible with both USB 2.0 and USB 1.1.
Measurement accuracy is achieved by the stability of the parts used together with the
computing power of the computer. Calibration data are part of the HW, which makes
it impossible to loose them (oppose to the calibration data located on the diskette).
Therefore, it is possible to simply connect the hardware to any computer (via USB 1.1
or USB 2.0 interface). All you have to do is just install the software.
The M570 series oscilloscopes allow user to measure waveforms using two
independent channels with resolution of 8 bits and sensitivity from 10mV/div to
5V/div (80mVfs to 40Vfs) in 9 steps. One division of the oscilloscope screen contains
32 dots. Input impedance matches the oscilloscope standards, therefore any regular
oscilloscope probe (with minimum compensation range of 32pF) can be connected to
the device. The software supports 1:1, 1:10, 1:100 and 1:1000 probes. AC or DC
coupling and type of probe can be independently selected for each vertical channel.
Any input can be grounded without disconnecting the probes from the measured
system. Vertical track position can be controlled with accuracy of 1 pixel of the
oscilloscope screen. Measurement can be triggered from the Channel A and Channel
B and/or blocked from Channel A, Channel B and/or External ARM input. Trigger
and ARM threshold can be set independently for each channel in the range of whole
oscilloscope screen with resolution of one pixel. Threshold of the External ARM input
is fixed to about 1.5V (TTL and CMOS compatible).
Each measuring channel of the M570 series oscilloscopes has its own AD
converter. No channel multiplexing is used for dual channel operation. Data are stored
in the internal dual port buffer of the device. The computer continuously reads data as
fast as possible (depending mainly on the operational system and other tasks opened).
If the computer interrupts reading for time longer then the time necessary to acquire
higher amount of data then the capacity of the internal buffer the buffer overflow
occurs. This situation is indicated by vertical red line. Probability of buffer overflow
is raising with higher sampling speed and higher amount of running applications.
During data acquisition it is recommended to close all applications, which are not
necessary for your current work.

3.3 Structure

The “Roll mode” control software consists of two independent applications.

- The data acquisition application controls device, measures and stores the

measured data.

- The data viewer displays the previously measured data and allows simple

voltage and time relation measurements.

These applications are independent. The only relations between them are the
measured data.

4. The data acquisition main window

The main window opens after the application starts. Most of the oscilloscope
functions are accessible via the controls located on this screen.

Fig. 4.1. – Main window

All controls connected to one of the channels have channel color.

TIP: The channel color can be changed in main menu.

4.1. Oscilloscope screen

The oscilloscope screen is located in the middle of the main window.

- 11 -

M570 series oscilloscope with rollmode User’s Guide

Fig. 4.1.1. – Oscilloscope screen

The oscilloscope screen is divided into 8 vertical divisions. The number of
horizontal divisions depends on the size of the application window and the screen
resolution.
There are three kinds of marks displayed on the screen.

- If the buffer overflow occurs, and some data are lost, data loss is marked by red
vertical line. This line marks the loose of data continuity.

- The device settings change is marked by read vertical line.

- If the data acquisition is blocked by ARM conditions, the data discontinuity is
marked by olive green vertical line.
The waveforms are displayed in the colors selected for each channel. The
default colors are: green for channel A and yellow for channel B.

TIP: The channel colors can be changed in main menu.

4.2. Grid controls

The cursors and grid controls are located in the left part of the main window.

Fig. 4.2.1. – Grid controls

“Grid” – switches the grid on/off

M570 series oscilloscope with rollmode User’s Guide

4.3. Channel visibility controls

The channel visibility controls are located in the left of the main window.

Fig. 4.3.1. – Channel visibility controls

“A“ – activates/deactivates channel A waveform
“B“ – activates/deactivates channel B waveform

4.4. Display mode controls

The display mode controls are located in the left of the main window.

Fig. 4.4.1. – Display mode controls

“BF“ – activates/deactivates „Beam finder“ mode. When activated, the
waveform exceeding vertical range is displayed as line on appropriate side of the
screen.
“Line“ – activates/deactivates mode, where the sample is connected with
adjacent one with line.

“Rew” (Rewrite) and “Roll” control the waveform drawing mode. When
“Rew” is selected, the waveform is always drawn from the left to right side of the
screen and the old waveform is continuously cleared off. When “Roll” is selected, the
waveform is drawn always on the right edge of the screen and rolls to left.

TIP: The “Roll” mode requires more processor time. If you display waveform
sampled with high sampling rate, choose the “Rew” mode.

“Display” – switches on/off the oscilloscope screen

TIP: Switching off the oscilloscope screen lowers the possibility of data loss.

4.5. Data save controls

The data save controls are located in the bottom of the main window.

- 13 -

M570 series oscilloscope with rollmode User’s Guide

Fig. 4.5.1. – Data save controls

The name of target file has to be inserted into the upper edit box.
The

button opens standard operating system dialog, where you can select
target file.
Click „Save“ to enter the “data saving” mode. The data are continuously saved
to disk during acquisition. The length of the file is indicated on the right of the “Size”
label.
“CLF” – (Clear file) erases the file

WARNING: The “Data save” controls are inactive, when the data acquisition is
in progress.

If the selected file already exists on the disk, measured data will be appended
to it.

4.6. Waveform display mode control

The controls are located in the bottom of the main window.

Fig. 4.6.1. – Waveform display mode controls

If more than 1 sample is displayed to one dot of the waveform, it is necessary
to set the mode of creating the dot. There are two buttons to choose the basic mode.

If “SNG” is selected, only the first sample of time period represented by the

dot is displayed.

If “Calc” is selected, the dot is calculated out of all samples. The method of

calculation depends on the following controls:
If the

is activated, the displayed dot is calculated as average of the

measured samples.
If the

is activated, the displayed dot is calculated as a maximum of

measured samples.
If the

is activated, the displayed dot is calculated as a minimum of

measured samples.

- 14 -

M570 series oscilloscope with rollmode User’s Guide

If both the

and are activated, the line between maximum and
minimum value of samples is displayed.
“Clear Scr” clears the oscilloscope screen.

4.7. Timebase controls

The timebase controls are located in the bottom of the main window.

Fig. 4.7.1. – Timebase controls

The scrollbar on the left side controls the sampling frequency. The actual
sampling frequency is shown above. Usable values are 50S/s to 5MS/s settable in 1-2­5 sequence.

WARNING: The fastest sampling frequency is usable only if the oscilloscope is
connected to computer via USB 2.0 interface. It is strongly recommended to close
any other application and choose the “Rew” display mode or switch the
oscilloscope display off (see chapter 4.4.). If the oscilloscope is connected to
computer via USB 1.1 interface the maximum usable sampling frequency is
250kS/s.

The scrollbar on the right side controls the display timebase. The following
information are displayed above this scrollbar:

- time of one grid division

- 1/time of one grid division

- number of samples aggregated to one screen point

TIP: For more information about display mode please see chapter 4.6.

If the change of one scrollbar results in lack of samples to create the dot, the
position of the second scrollbar will be adjusted to get one sample for each displayed
dot.

WARNING: If the scrollbar position is adjusted due to above mentioned reasons
automatically, it won’t be readjusted back, when the reasons are gone.

4.8. Data acquisition mode control

The data acquisition mode control elements are located in the bottom of the
main window.

- 15 -

M570 series oscilloscope with rollmode User’s Guide

Fig. 4.8.1 – Data acquisition mode controls

These controls allow to set mode of data acquisition start and its length.
The controls located in the left side sets the length of data acquisition. When
the “Cont” button is pressed, the continuous mode of data acquisition is selected. In
this case, only way to stop the data acquisition is pressing the “Stop” button located
on the right side of this group.
Pressing the “DEF” button activates the “Length” edit box. Now it is possible
to enter the length of the data acquisition in hours, minutes and seconds. “h” means
hours, “m” minutes and “s” seconds. For example 2h35m25s means two hours, 35
minutes and 25 seconds.
Controls on the right side of the group define the conditions for the start of
data acquisition and start or stop it.
The “FR” button sets the free run mode. In this mode the data acquisition
starts after pressing the “Start” button immediately.
The “TR” button sets the triggered mode. To start the data acquisition it is
necessary to press the “Start button” and then to reach the trigger conditions selectable
by “trigger controls” (see. chapter 4.9.).
Pressing the “Start” button starts the data acquisition according to the
conditions mentioned above.
Pressing the “Stop” button stops the data acquisition immediately.

4.9. Trigger controls

These elements are located in the bottom side of the main window. They have
effect only if the triggered data acquisition mode is set (see chapter 4.8.)

Fig. 4.9.1. – Trigger controls

The first row of the control elements represent Channel A, the second one
channel B trigger condition settings. The left button (“A” and/or “B”) activates the
trigger condition for Channel A, or Channel B. The buttons located in the middle
column set the relations to value written in edit boxes located at the right side of the
group. The value written to these boxes represents voltage in volts or milivolts (m).
The button located in the bottom row of the group becomes active if both
trigger conditions for Channel A and Channel B are activated. It defines the influence
of each of the channels on the trigger event. It can be set to one of the following
states:

- “AND” the data acquisition starts if both conditions are met

- 16 -

M570 series oscilloscope with rollmode User’s Guide

- “OR” the data acquisition starts if any condition is met.
The “TGD” indicator changes its color under the following conditions:

- it is red if the trigger condition did not occurred yet

- it is green if the trigger condition has already occurred.

WARNING: ARM-ing circuitry (see chapter 4.10.) have higher priority than the
triggering circuits. If the triggering circuits are set to the conditions under which
the data acquisition is blocked (by ARM-ing circuitry), the acquisition will never
start.

4.10. ARM-ing the data acquisition

Located in the bottom right side of the main window, these control elements
allow to set conditions under which the data acquisition is interrupted. The reason of
interruption can be the voltage measured by each channel and/or logic level on the
“E” input of the instrument.

Fig. 4.10.1. – ARM control elements

The first and second row of the control elements represents the Channel A and
Channel B ARM condition settings. The left button (“A” and/or “B”) activates the
ARM conditions for Channel A or Channel B. The buttons located in the middle set
the relations to value written in edit boxes located at the right side of the group. The
value written to these boxes represents voltage in volts, or milivolts (m). If the
condition set is FALSE the data acquisition is interrupted. It starts again when all
active conditions are met.
There are two buttons in the bottom row. When the “E” button is active the
data acquisition is controlled also by the “E” input of the device. This input is
LVCMOS 3.3V compatible with threshold of about 1.5V. The button located on the
right side defines the ARM condition for the “E” input. If it is set to “0” the data
acquisition will be interrupted if the “E” input is connected to log. 1. If it is set to 1,
log.0 interrupts the data acquisition.
If there are several ARM inputs set to active state, every active condition must
be met to allow data acquisition.

TIP: Internal 10 kOhm pull-up resistor is connected between “E” input and 3.3V
power supply of the oscilloscope. This sets log.1 to unconnected input. This
condition can be used for simple data acquisition control. If only the E arming
condition is active and set to 1, grounding the “E” input interrupts the data
acquisition. If the condition is set to 0, grounding the “E” input starts the data
acquisition.

The “ARM” indicator changes its color under following conditions:

- 17 -

M570 series oscilloscope with rollmode User’s Guide

- it is red, if the data acquisition is not started (and triggered) yet

- it is yellow, if the data acquisition has started already, but it is interrupted by ARM­ing system

- it is green if the data acquisition is in progress.

4.11. Vertical range controls

The vertical range controls are located in the right of the main window.

Fig. 4.11.1. – Range controls

Channel A controls are located in left, channel B controls are located in the
right side.

5. Data viewer main window

Figure 5.1. shows the main window of the data viewer.

Fig. 5.1. – The data viewer main window

The main window consists of the waveform screens, control elements, set of
measured data and the main menu. The first operation you have to perform is opening
the data file you want to view. If no file is opened, most of the control elements are
inactive.

5.1. Opening the data file

The viewer is designed to use data created by the “Roll mode” of M570 series
oscilloscopes. Every file is created with extension “rmd”. Structure of the data file is
designed for handling huge amount of data. To speed up operations with the data file
some data integrity checks are not performed. Please note that opening the file
containing data incompatible with the viewer data structure can lead to unpredicted
behaviour of the viewer.

WARNING: Opening the incompatible file can lead to unpredictable behaviour
of data viewer.

The control elements for opening the data file are located on the lower left side
of the screen.

M570 series oscilloscope with rollmode User’s Guide

Fig. 5.1.1. – Data file control elements

The file name has to be inserted into the upper edit box.
The

button opens standard operating system dialog, where you can select
the target file.
Click „Open“ to load data.

The length of the file is indicated on the right of the “Size” label.
The “progress” bar located on the right bottom side of the screen indicates the

state of the load operation.

5.2. Waveform screens

The waveform screens are shown on the fig. 5.2.1. They are used to display
the whole data stored in the data file, part of data stored in internal buffer of the
computer and part of data used for detailed measurements.

Fig. 5.2.1. – Waveform screens

The “file screen” is located on the bottom side of the screens. It shows whole
data stored in the data file (Fig.5.2.2). The violet color bar marks the data area cached
in the internal waveform buffer of the computer. By moving this bar it is possible to
change the content of the internal buffer. To move this bar click on screen on left or
right side of it, click on arrows or simply drag it to desired position.

Fig. 5.2.2. – File screen

M570 series oscilloscope with rollmode User’s Guide

WARNING: Moving data to internal buffer is the time consuming operation.
The reaction to bar movements can take several seconds.

The waveform stored in the internal buffer is displayed on the screen
positioned right above the file screen. Fig. 5.2.3. shows this “Buffer screen”.

Fig. 5.2.3. – Buffer screen

The brown color bar marks the area displayed on the screen called “Main
screen”. This screen shows detailed waveforms and allows cursor measurements. The
brown color bar can be moved over the buffer screen. Moving this bar changes the
content of the main screen.
The main screen occupies the largest part of the screen area (fig. 5.2.4.).

Fig. 5.2.4. – Main screen

Its vertical resolution is 256 points. It is able to display all details of the
waveform. There are auxiliary information displayed on the bottom of this screen.
From right to left: The real time of the left edge of the screen, horizontal grid size
(time) and time between the screen cursors (red and blue cross).

VARNING: Any place of the data can be marked by the time synchronization
mark. The real time of the marked place can be set to any value. The real time of
the left most edge of the screen is related to this mark. Sometimes it can be a
negative value.

In addition to the waveforms, three types of cursors can be displayed on the
main screen.

5.3. Cursors

There are three types of cursors to perform measurements on the waveforms.

- time synchronization mark

- waveform cursors

- 24 -

M570 series oscilloscope with rollmode User’s Guide

- screen cursors

The first and the second one are usable for time relation measurements. The
screen cursors are usable for both time and voltage measurements.
The time synchronization mark can be set to any place of the whole waveform.
The time of this place can be set to any value. Any “real time” information will be
calculated using this time. If the time synchronization mark is not used or it is deleted,
the “real time” information are synchronized with the beginning of the measurement
with time 0.
It is possible to place 10 “waveform cursors” (including the time
synchronization mark) to whole waveform. The positions of these cursors are shown
on all screens. They have different colors and names (C0 – C9). They are usable to get
“real time” information of their positions, information of time periods between these
cursors and the time period between the position of any of these cursors and the red
screen cursor. It is also simple to change the position of the main screen for displaying
the waveforms around any of these cursors (see chapter 5.3.1.).
It is possible to activate two ”screen cursors” on the main screen. They are
displayed as the red and blue crosses. The information about the time period between

these cursors is displayed under the screen (i.e.

). The results

of voltage measurements using these cursors are displayed above the main screen.

5.3.1. Using cursors

Click right mouse button on the main screen to pop-up menu.

Fig. 5.3.1.1. – Cursor manipulation menu

Add waveform cursor – Adds waveform cursor. It is possible to drag it to any
place of the main screen. The image of this cursor is also added to the file and buffer
screens. The cursor is visible on main and buffer screen depending on their content.

Set time synchro – Creates time synchronization mark, if it is not already
created. The mark has real time value 0 and it is possible to drag it to any place of the
main screen.

Bring cursor – Moves selected waveform cursor to the main screen. After
activation of this function the cursor selection menu will be displayed.

M570 series oscilloscope with rollmode User’s Guide

Fig. 5.3.1.2. – Cursor selection menu

Delete last cursor – Deletes the last added cursor

Delete all cursors – Deletes all waveform cursors

Display times – Displays time periods between cursors

Fig. 5.3.1.3. – Time periods table

Because the string of the displayed time could be too long to display, if you
locate the mouse over the time string, the full information will be displayed. The time
periods are displayed including information of the relation of the cursors. It is the
difference between position of the cursor from the upper row and the cursor from left
column. If the time period value is negative, the cursor from left column points to
later time than the cursor from upper row.
Click “Export to clipboard” to save the time periods information to the
clipboard. The data consists of the pair of cursor’s names followed by data period
information (from position of the second cursor is subtracted the position of the first
one). The example of the clipboard export follows:

The entered attributes become active after clicking on the “OK” button.
Clicking “Cancel” closes the window with no property changes.

Clicking on the time synchronization mark opens different window.

Fig. 5.3.1.6. – Time synchro mark modification window

Cursor color – Change the cursor’s color

Cursor name – The name of the selected cursor

Time – Sets the real time of the time synchronization mark position. All real time

information will be related to this time. The following format is usable to enter the
time: xxhyymzz.zzzs. Where xxh – time in hours, yym – time in minutes, zz.zzzs –
time in seconds. While entering the time information the color of the string is blue. It
changes to black after pressing the “ENTER” key. Then it is possible to click to
“OK”, or “Cancel” as it is described above.
Fig. 5.3.1.7. shows the viewer screens with screen cursors activated. The
screen cursors can be activated/deactivated using the “Cursors” button above the
screens. There are nine waveform cursors and the time synchronization mark
positioned over the waveform. If the screen cursor or the time synchronization mark is

- 29 -

M570 series oscilloscope with rollmode User’s Guide

not visible on the main screen, its position is marked by left or right pointing triangle.
The color of the triangle is the same as the color of the cursor.

Fig. 5.3.1.7. – Viewer screens with waveform cursors and time synchro mark

The relative position (order) of these triangles is the same as the placement of
the cursors.
Positioning the mouse cursor to the triangle, the real time of the cursor
position and the time period between the red screen cursor and the selected waveform
cursor (or synchronization time mark) is displayed. If the waveform cursor is visible
on the main screen, positioning the mouse cursor to it has the same effect as the
positioning to the triangle. If the screen cursors are not active, the time period
between the waveform cursor and the red screen cursor is not displayed.
The triangles are also usable to change the main screen position in the
waveform. Clicking to triangle changes the position of the main screen to display
waveform around the selected cursor (or time synchronization mark).
The screen cursors are also usable to measure voltages. The voltage of the
vertical position of red cursor, blue cursor and voltage between red and blue cursors
(for channels A and B) are displayed above the screen.

5.3.2. Measuring non-continuous data

Two types of discontinuity can occur:

- Internal buffer overflow during data acquisition.

- Discontinuity caused by ARM-ing data acquisition.
The result of a time period measurement with time discontinuity caused by
internal buffer overflow is displayed in red color, or as a string followed by “!”
character. This indicates, that the displayed time is not correct.
If the time break is caused by ARM-ing the data acquisition, the time can be
reconstructed and there is no difference between displaying the result of

- 30 -

M570 series oscilloscope with rollmode User’s Guide

measurements with no time discontinuities and with time discontinuities caused by
ARM-ing.

5.4. Channel visibility controls

The channel visibility controls are located in the left of the main window.

Fig. 5.4.1. – Channel visibility controls

“A“ – activates/deactivates channel A waveform
“B“ – activates/deactivates channel B waveform
The buttons on the bottom row are reserved for future use and have no effect.

5.5. Waveform display mode control

The controls are located in the bottom of the main window.

Fig. 5.5.1. – Waveform display mode controls

If more than 1 sample is displayed to one dot of the waveform, it is necessary
to set the mode of creating the dot. There are two buttons to choose the basic mode.

If “SNG” is selected, only the first sample of time period represented by the
dot is displayed.

If “Calc” is selected, the dot is calculated out of all samples. The method of
calculation depends on the following controls:

If the

is activated, the displayed dot is calculated as average of the

measured samples.
If the

is activated, the displayed dot is calculated as a maximum of

measured samples.
If the

is activated, the displayed dot is calculated as a minimum of

measured samples.
If both the

and are activated, the line between maximum and

minimum value of samples is displayed.
