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).

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.

Virtual digital oscilloscopes, 60 MHz II - 9

• 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.

Changing the IP address

Our

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.

The IP address can be changed from the Tools 

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.
