At first start-up the following windows are opened:
Enter a "name" for the instrument (by default MTX 162 is selected); the instrument configuration files will be associated to this name.
Restarts a search for connected instruments
launches online help for this window.
The SCOPEin@BOX_LE software automatically searches for MTX 162 oscilloscopes connected to the PC WiFi if equipped). It then displays the list of these instruments with, for each one:
- its generic name,
- the onboard software version
- the serial number.
The selected MTX 162 oscilloscope's IP address and the PC's address are displayed.
Press the key to refresh the display if your oscilloscope does
not appear in the list of connected instruments. If this fails, check your instrument's connection and/or re-start it by disconnecting and reconnecting it to the power supply.
1. Name your instrument.
2. Select one of the instruments connected to the PC (via USB or ETHERNET) from the proposed lists.
3. Click on the button to create and launch the instrument.
In our example we are starting up the "MTX 162UEW"
oscilloscope for the first time. By default the instrument's IP address is 192.168.0.100 (with the
55.255.255.0 network mask).
2 The instrument's IP address must therefore be adapted to the
network address used by the host-PC (here: 14.3.212.31).

The selection of an instrument connected using Ethernet leads to the display of the following window if the IP address, entered by default, is not compatible with the network to which the PC is connected:
To avoid IP address conflicts on the network you are using, consult your administrator in order to select an available address that is compatible with the network.
In our example the network mask used is 255.255.0.0; we program our
IP address: 14.3.215.215 and validate the entry using the key.
The IP address is tested on validation to make sure that the entered address is not already used on the network.
If the result is correct the instrument starts up.

This window contains the graphical representation of the signals:
2500 points per channel are used to display curves.
They are sent from the oscilloscope to the PC via the communications interface (USB / ETHERNET / ETHERNET WiFi).
These 2500 points are different depending on the activation or not of the FFT calculation:
- when FFT is not active,
to avoid erroneous graphical representations related to the selection of one point in 20 (the acquisition memory being 50 000 points), the 2500 points sent to the PC are in fact 1250 couples (min, max) of the extreme values encountered in each 40 point interval in the acquisition memory.
- when FFT is active,
the points that are sent are also used in the Fourier transformation and the use of the couples (min, max) would lead to an erroneous frequency representation. They are therefore obtained using a basic decimation (1 point every
20) of the content of the acquisition memory. Erroneous temporal representations on the screen are therefore possible.
if the zoom is activated, 2500 additional points are sent (double time
base).
These 2500 points are generally couples (Min, Max) except for when
he zoom is at its maximum and the 2500 viewed points correspond to
t a continuous series of points from the acquisition memory.

Programming the WiFi connection

Only the MTX 162UEW versions have the wireless communication option: WiFi.
This WiFi function is compatible with the IEEE 802.11b and g wireless communications standards, and for security it is compatible with the 802.11i Encryption standard.
The MTX 162UEW can be used in one of the network topologies described by this standard:
- the infrastructure topology, in which wireless clients are connected to an access point that permits the interconnection of this wireless network to a cabled network.
- the Ad Hoc topology, in which the clients are connected to each other without any access points. This mode makes it possible, for example, to connect one or more oscilloscopes directly to a PC.
It is strongly recommended that you protect your netwo encryption and authentication mechanism, the MTX 162UEW manages the WEP (64 and 128 bits), WPA and WPA2 security modes. The latter two are to be privileged in terms of security.
However, when in Ad Hoc mode, only WEP security is supported.
The MTX 162UEW operates in roaming mode. It is therefore capable, in an adapted network, (that has several access points with the same network name (SSID) and the same security characteristics), of automatically switching to the access point that has the greatest transmission power.

'Persistence' simulates the analogue persistence of the displays on cathode tube screens by keeping the 8 last traces for each channel, the brightness of the colour shows the age (the brightest colour shows the most recent trace).

Auto

The trigger is essential to obtain a correct representation of the signal.
Its setting is made using 5 settings that can be accessed from the "Oscilloscope control" window which are:
the mode
the filter
the front selection
the source
the level
The Trig LED on this block shows the presence of triggering events.
4 trigger modes are available:
for automatic; this mode guarantees signal acquisition even in the absence of trigger conditions. If no pulse is detected for approximately 500 ms, the oscilloscope switches to automatic triggering and regularly, with a period < 80 ms, generates virtual triggers making it possible to have acquisition If pulses are detected (signal frequency > Hz and level correctly adjusted), the automatic mode operates as the triggered mode.
When the oscilloscope switches to triggered mode (without trigger
signal), the trace is no longer stabilised on the screen, the averaging of the "envelope" modes, if they are triggered, can then give erroneous representations and erroneous automatic measurements.

Trig

Mono

for "triggered"; in this mode each detection of a trigger event (ascending or descending wave) on the signal selected as the source, causes a trigger that makes it possible to complete the current acquisition. A new acquisition is immediately begun to anticipate the next trigger event. In the absence of a signal the acquisition is not completed ('Ready' status), the trace is not, therefore, displayed.
for single; a single acquisition is run and continues until a trigger event is detected.
Pressing on resets the trigger for a new acquisition.
Trigger events are only taken into account once the Pretrig phase
is complete (filling of the memory between the origin of the window and the trigger's horizontal position). A horizontal positioning of the trigger on the left of the screen is used to reduce the acquisition time.

Filter

Source

To limit false triggers or to adapt to a signal that is used as a trigger source 4 filters are available:
AC cuts the continuous component of the signal (see remark below).
DC
lets the signal pass without filtering (the continuous and alternative components are kept).

LF Reject activates a high-pass filter (cut-off frequency 10 kHz).

HF Reject activates a low-pass filter (cut-off frequency 10 kHz).

The coupling of the channel, selected in the vertical block of the control panel is input to the acquisition string. Consequently, if the AC input coupling is selected, the DC component of the signal is removed on the CHx channel and on the trigger source CHx (the AC or DC filtering of the trigger gives the same result).
3 trigger sources are available: CH1, CH2 and LINE.
LINE is used to trigger on the power supply voltage to which the instrument is connected. In this case only the trigger wave (ascending or descending) can be programmed. The trigger representation on the trace is a vertical blue line, the notion of level (vertical position) is no longer available.

General autoset

As with a traditional oscilloscope, the correct representation of a signal necessitates making a number of adjustments:
Choice of the channel
Trigger
Time base
Vertical sensitivity
etc. …
Your oscilloscope proposes different strategies in order to obtain these adjustments in the best conditions.
It defines all the instrument settings including the search for a signal on all channels, the trigger settings and the time base. The signal frequency must
be
20 Hz for the autoset to succeed.
≥≥
This action has a momentary effect after which it is possible to take over manually using the classical commands.
When the autoset succeeds it overwrites all the current settings.
Otherwise it has no effect on the current settings.
When 2 signals with different frequencies are present on the inputs, the trigger is forced on the lowest frequency signal and the time base is adapted to this signal.

Vertical autoset

Vertical autorange

Horizontal autorange

By default the time base is calculated in order to view at least 3 signal periods. If the FFT is activated the time base is calculated so that the fundamental of the frequency representation is at approximately one division from the origin of the frequencies.
This command is specific to the associated channel (CH1 or CH2).
It activates the channel, adjusts sensitivity, offset, coupling (if DC coupling is selected and offset is possible) to better adapt to the trace display.
It is a momentary action.
When vertical autoset succeeds it overwrites the current settings.
If it fails the channel remains selected with its initial settings.
This function permanently adjusts the sensitivity on the signal amplitude on condition that the signal's points have been acquired (select the AUTO trigger mode if there is no trigger).
This function only works on the channel selected as the trigger source. It permanently searches for the time base which is best adapted to view this trace (display of at least 2 periods on the screen).

Making measurements from the trace

Selecting the reference channel

Once the representation of the traces has been obtained a more in-depth analysis of the signals can be undertaken by making a few measurements on the signal.
Two categories of measurements can be made using the MTX 162:
1. manual measurement using the cursors
2. automatic measurements
In both cases the measurements are made on the channel that was selected as the reference.
It is selected:

1. Min/Max high resolution acquisition

2. Averaging the trace

In order not to hide the rapid voltage variations due to signal sub-sampling for slower time bases the MTX 162 has a Min/Max high resolution acquisition mode.
When this option is activated each pair of acquired points is the result of a search for extreme min. and max. values from all the samples acquired using the highest sampling speed, i.e. 50 MSamples/s.
This Min/Max acquisition mode guarantees that any peaks in voltage of more than 40 ns width are seen and displayed on the oscilloscope screen.
This mode is activated from the 'Horizontal’ menu:
To reduce the random noise observed on the signals it is possible to average the acquired samples.
The calculation is made using the following formula:

The settings needed for this function are concentrated in the FFT block on the "Oscilloscope Control" panel.
Logarithm scale:
- The vertical sensitivity of the FFT representation is of 10 dB/div.
- The 0 dB position corresponds to the top part of the screen.
The trace can be offset from +60 dB to -140 dB.
Linear scale:
- The vertical sensitivity of the FFT representation is that of the channel.
- The 0V position places the channel reference in the 'Trace FFT' window on the 1st division from the bottom of the screen. The offset is adjustable from 0 to 8 div.
This sensitivity is directly related to the time base of the time representation (unit Hz / div. : 12.5 / time base). It varies from 62.5 mHz to 125 MHz.

c) Interpreting
the FFT
The Fourier Fast Transformed (FFT) is used to calculate the discrete representation of a signal in a frequency domain using its discrete representation in the time domain.
FFT can be used for the following applications:
measuring the different harmonics and the distortion of a signal,
analysing an impulse response,
searching for sources of noise in logical circuits.
The Fourier fast transform is calculated using the equation:

where: x (n) : a sample in the time domain X (k) : a sample in the frequency domain N : FFT resolution n : time index k : frequency index
This calculation is made on 2500 points obtained by selected one point every 20 in the acquisition memory. These same points are used for the non zoomed time representation in the "Oscilloscope Trace" window.
The finite duration of the studied interval is shown by a convolution in the signal's frequency domain using a sinx/x function. This convolution changes the FFT graphic representation because of the lateral lobes that are characteristic of the sinx/x function (except if the study interval contains a whole number of periods).
Before calculating the FFT, the oscilloscope weights the signal to be analysed using a window that acts as a high-pass filter. The choice of a type of window is essential to distinguish the different signal rays and make precise measurements.

This error is related to the FFT calculation when there is not a whole number of periods in the observation window.
Thus, with a 'Flat Top' window, the 0 dB level is obtained on the ray of the fundamental of a sinusoidal 1 Vrms amplitude signal.
Be careful to respect the Shannon theory, i.e. that the sampling frequency "Sf" must be greater than 2 times the maximum frequency containing by the signal.

In order not to deform the spectral content of the signal and obtain a better FFT calculation precision it is recommended to work with a peak to peak amplitude of 3 div. to 7 div.
Too weak amplitude leads to a reduction in the precision and a too high amplitude of over 8 divisions causes signal distortion, this causes undesirable harmonics to appear.
The simultaneous time and frequency representation of the signal eases the surveillance of the changes in signal amplitude.
Effects of under-sampling on the frequency representation: If the sampling frequency is not adapted (less than double the maximum
frequency of the signal to be measured) high frequency components are under sampled and appear on the FFT graphical representation by symmetry (folding).
The "General Autoset" function avoids this phenomenon and adapts the
horizontal scale so that the representation is more legible.

Exporting to EXCEL from the "Oscilloscope Control" panel causes a new capture and therefore the loss of the current capture. The following message appears:
If you wish to export the current captures click on 'No'.
To exit close one of the "Capture" windows:
or
The closure of the 'Capture' windows leads to the permanent loss of the traces. If you wish to keep the captured traces to work on them further stop acquisition, make a backup of the signals in question in a ".TRC" file just after having carried out the capture. All that needs to be done then is to recall these traces and make a new capture with these MEMx traces (see §. Recalling the trace).

Freezing, Saving, Displaying the trace

1. Freezing the trace

Traces of channels
Frozen traces of
channels CH1 and CH2
To highlight an eventual signal variation it is possible to freeze the traces at a point in time. These traces appear in a light colour in the 'Oscilloscope Trace' window.
A trace can only be frozen if it is on the screen.
This trace "snapshot" is made using the button on the tool bar. Pressing the button again erases the current frozen traces.
The frozen trace is not lost if you exit and open new work session
using the same instrument configuration file

acquisition time base

De-selecting a channel permanently deletes its snapsho
These frozen traces are static display data: activating the zoom therefore has no effect on them and they cannot be moved up or down.
For a zoom the
frozen traces
only appear on
the zoomed
graph.

2. Saving the trace

a) ".TRC" saving

Example
The MTX 162 gives the possibility of saving the traces displayed on the screen.
Two memorization formats are available: ".TRC" or ".TXT".
In both cases the 50 000 acquired samples that form the trace as well as the data relating to the acquisition and making it possible to interpret the data are transferred to the PC are backed up.
This is the only format that can be used to reload a trace into the oscilloscope (see §. Recalling the trace). It is a binary file with a ".TRC" extension that can only be used by the SCOPEin@BOX_LE software.

3. Recalling the
trace
Example
Only the trace files backed up using SCOPEin@BOX_LE and having the ".TRC" extension can be recalled by the application.
These traces can replace either the CH1 and/or the CH2 traces.
In the 'Oscilloscope Control' window the channel name is displayed as MEMx, and the settings for the vertical block for the channel in question are updated using the values contained in the file. The acquisition time base of the recalled trace and the file name are displayed instead of .
The deletion of the recall is made by de-selecting the MEMx channel which returns to CHx.
The recalled trace behaves in the same way as a normal trace: they
can moved up or down and all the available automatic or manual measurements can be carried out.

Memorizing, Recalling the configuration

Memorizing, Recalling the configuration
The general instrument configuration is the set of data that makes it possible to restart the device in the same status as it was in when the last session was closed.
An automatic backup of the general configuration is made every time a session is closed.
This general configuration is stored at the same level as the "SCOPEin@BOX_LE.exe" executable on the PC's hard drive.
It has three files:
setup.7up
This is the configuration file for the SCOPEin@BOX_LE software; it contains the following data:
- first install indicator
- language used
- software work directory
<nameInstrument>.INI
where <nameInstrument> is the name given to the instrument when a session is created.
<nameInstrument>.INI.CFG
The ".INI" file is the PC configuration, it includes the following data:
- the size and location of all the open windows
- the access paths to the various directories (trace backups, configurations, software updates...)
- identification of the software and equipment versions
- information relative to the instrument being used (oscilloscope name, serial number, MAC address, IP
dress …)
ad
- the previously used communication mode (Ethernet/USB)
- trace references
- etc. …
The ".CFG" file is the oscilloscope configuration, it contains all the current instrument settings.

Memorizing, Recalling the configuration (continued)

1. Memorizing the configuration

Example
This backup only covers the oscilloscope configuration, the PC configuration is specific to the open session.
During the backup the oscilloscope configuration is stored in a file with a ".CFG" extension which it is recommended to place in a specific directory in order to differentiate it from general configurations (in the example below we have created a CFG directory).
The access path to this directory is memorized in the PC configuration so that the user will be directed to this directory by default for all operations pertaining to configuration management.
Backup of the oscilloscope configuration in config1.cfg.

Exporting the trace to EXCEL

Exporting the trace to EXCEL
To export the trace the PC must first recall the 50 000 samples acquired from the oscilloscope; this is why the Capture windows open if they are not already open.
The samples can be transferred to EXCEL in three ways:
by clicking on the button in the tool bar,
from the 'Tools/Export to EXCEL…' menu
from the "Capture: Oscilloscope Control" window by pressing the
