Simple to use, no adjustments are needed for a local application.
ETHERNET Depending on the oscilloscope equipment Ethernet can be connected:
- using a cable (straight cable for connection to a network or crossed
for local use)
- or wireless using WiFi (MTX 162UEW only).
Powering up Before powering up your oscilloscope and its connection to the Host-PC, insert the
supplied CD ROM and install the SCOPEin@BOX_LE driver software.
Then, connect the oscilloscope:
• either to the PC by USB using the supplied USB A/B cable
• or to the PC on the ETHERNET local network (point to point) using a
crossed ETHERNET cable
• or to the ETHERNET cable network using a straight ETHERNET cable
• if your oscilloscope has the WiFi option (MTX 162UEW), you must first configure
this connection mode before being able to use it (see chapter III).
Finally, connect the power supply cable to the power outlet and refer to the
following paragraphs.

First use
Command software The command software is SCOPEin@BOX_LE.exe :
Installation Carefully read the safety instructions shipped with the instrument and
insert the CDROM in your PC CD drive.
Launching When the oscilloscope's "READY" LED lights, you can launch the
SCOPEin@BOX_LE.exe software.
First start-up At first start-up the following windows are opened:
 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
255.255.255.0 network mask).
The instrument's IP address must therefore be adapted to the
network address used by the host-PC (here: 14.3.212.31).
The SCOPEin@BOX_LE software automatically
searches for MTX 162 oscilloscopes connected to
the PC
by using USB, or ETHERNET (RJ45 cable or
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.
Enter a "name" for the instrument (by default MTX
162 is selected); the instrument configuration files
will be associated to this name.
The selected MTX 162 oscilloscope's IP address
and the PC's address are displayed.

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.

descriptions
When the instrument is launched the "Oscilloscope Control" and
"Oscilloscope Trace" should be displayed.
"Oscilloscope
Control"
This window contains all the possible settings for the oscilloscope:
"Oscilloscope
Trace"
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
the zoom is at its maximum and the 2500 viewed points correspond to
a continuous series of points from the acquisition memory.

blink (unless communications with the instrument cannot be
established).
Starting a new
oscilloscope
Use the key to open the "Create a new instrument" window
(see chapter II, §. First start-up).
Our
recommendations
If a communications mode is not operational:
• Make sure that the instrument is connected: disconnect the cables (USB
and Ethernet) and reconnect them.
• For driving using Ethernet check that the cable used is adapted to the
type of connection you wish to make (the green Ethernet RJ45
connector LED lights if the connection is operational):
- Straight-thru cable for connection to a company network
- crossover cable for a local connection to the PC
 Recent network cards accept a straight-thru cable for a direct
"instrument to PC" connection.

For Ethernet, make sure that:
• the IP address in the configuration file is the same as the address
programmed in the oscilloscope: click on and find your
instrument in the list of connected devices, or start-up the
instrument using USB; check the network parameters using the
Tools menu (see below).
• the oscilloscope's IP address is not already used on the network
and does not cause an addressing conflict:
- disconnect the network cable from the oscilloscope, run a 'ping <IP
address>’ command from your DOS Command screen (menu
'Start/Run…’ and open 'cmd').
If an instrument responds, change the IP address.
- If the problem persists, close the SCOPEin@BOX_LE application,
disconnect it, then reconnect the power supply on the MTX 162 to
reinitialise it.
When the "READY” LED lights, re-launch the application.
Changing the IP
address
The IP address can be changed from the Tools 

 Network… menu in the
"Oscilloscope Control" window:
The key gives access to the network mask and gateway
programming.
Once the new IP address has been entered click on to validate it.
The address is then controlled before programming to make sure that the
entered address is compatible with the network and is not currently in use.
If the instrument is driven via Ethernet, the connection is stopped and
reinitialized using the new address settings.

Following start-ups (continued)
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 network using a data
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.
The WIFi settings cannot be changed if the device is using this
communication method. It is therefore necessary to return to a cable
connection first (USB or Ethernet).
If the oscilloscope is currently in WiFi mode it can be connected using the
'Tools' menu:
To continue, connect one of the communication cables to your oscilloscope
and click on to start a new connection.

Our
recommendations
If the WiFi connection is not operational in the 'Start of an oscilloscope'
window:
- Make sure that the WiFi connection settings for your oscilloscope are
identical to those programmed on your wireless access point.
- Use the key in the WiFi programming window, to assess the
reception level and, if needed, move your MTX 162UEW oscilloscope
closer to your access point in order to check whether you have a range
problem.
- Make sure (especially when switching from Ad Hoc / Infrastructure)
that the oscilloscope's IP address is compatible with the rest of the
equipment.
- For use in an Ad Hoc topology (PC + MTX 162UEW), it is imperative
to establish the Ad Hoc connection on your PC before starting the
network search on the oscilloscope (powering on the oscilloscope).
