Initial operation of
the oscilloscope The portable oscilloscopes in this range are designed to operate on a power
source delivering 98 to 264 V (ACrms) or in stand-alone mode with a
battery.
The instruments are delivered with a mains adapter, an external power
supply (battery charger) and a NiMH battery (9.6 V, 3.5 A/h).
Fuse
Type: time delay, 2.5 A, 250 V, 5 x 20 mm
The external power supply is equipped with a protection fuse that must only
be replaced with an identical model.
Replacement must only be performed by qualified personnel.
Contact your nearest service center.
Starting up with the
external power
supply
•Connect the 4-point lead of the external power supply to the "'DC-Input"
socket located on the side of the oscilloscope.
*Do not insert any metal objects into this lead.
•Connect the mains lead from the external power supply to the external
power supply.
The POWER LED on the adapter lights up, indicating that it is live.
The CHARGE LED flashes, indicating:
•the absence of the battery or
•slow charging of the battery, if it is present in the oscilloscope.
Press the instrument's ON switch: it lights up and then a clock is displayed
on the screen during the start-up sequence.
The message "Instrument start-up" is displayed.
The oscilloscope is then ready for use.
By default, the "Advanced" mode is not active (see page 90).
*
The symbol in the display area for the current value means
that the instrument is connected to the AC power supply.

Installation of the
battery in the
oscilloscope
*To prevent any electric shocks, remove the Probix adapters and the
external power supply lead before installing or replacing the battery.
•Using a coin or a screwdriver, turn by a quarter turn (counter-clockwise)
the 2 plastic screws located on the cover of the battery compartment
located at the rear of the instrument
•Lift the cover of the battery compartment by inserting the coin under the
slot at the top of the cover.
•Then connect the 4-point battery connector to the connector located
inside the battery compartment of the oscilloscope, taking care to
respect the failsafe systems.
•Position the battery inside the oscilloscope compartment (battery wires
at the bottom of the oscilloscope's battery compartment).
•Close the cover of the battery compartment and lock it by turning the 2
plastic screws by one quarter turn (clockwise).
Changing the
battery Follow the same procedure and make sure that the replacement battery
model is identical to the original one.
The oscilloscope contains a NiMH battery. The flat battery must be handed
over to a recycling firm or a company specialized in the treatment of
dangerous waste materials. Never dispose of the battery with other
solid waste.
For further information, contact your nearest service center.
When the oscilloscope is delivered, the battery may be discharged and
require a complete recharge. Full charging of the battery will then take
about two and a half hours, with the oscilloscope switched off.

Charging the battery
*
Once the battery is located in its compartment, follow the external power supply
start-up instructions.
•To speed up recharging of the battery, switch off the power to the
oscilloscope by a long press on the ON/OFF button.
•Battery fully discharged: during the first 10 minutes, the CHARGE LED of the
external power supply flashes, indicating that the battery is slow-charging.
The CHARGE LED then lights up when it switches to fast-charging.
During the charging of the battery (after 15 min), the startup of the
oscilloscope causes the premature stop of the load. It is possible to restart
the charging while disconnecting, then reconnecting the charger.
The LED goes out when the battery is fully charged (approx. 2h30).
Charging the battery
while using the
oscilloscope
When the oscilloscope is connected to AC power via the external power supply,
it is possible to perform slow-charging of the battery.
The CHARGE LED of the external power supply lights up. Full recharging of a
totally discharged battery then takes approx. 5 1/2 hours. The LED goes out
when the battery is fully charged.
*Frequently recharging a battery when it is not fully discharged reduces its life
span.
Powering the
instrument with the
battery
When the oscilloscope is powered by a battery, an charge status indicator is
included in the display area of the current value:
The battery is 100% charged
The battery is 80% charged
The battery is 60% charged, etc.
If only one charge level is present, it means that the battery can
only operate for a few minutes more, so you are advised to
recharge it or switch to the AC power supply.
The battery is total
ly dead and the screen is about to be deactivated. You must
either recharge the battery or connect the instrument to the
external power supply.
If you change battery, a complete battery charge and discharge cycle (until the
instrument is automatically deactivated when discharging has finished) is
essential to calibrate this indicator.
To maintain the battery in good condition, use the oscilloscope at least until
the level before recharging.

Description of the instrument (cont'd)
The various instrument parameters can be accessed via menus.
The rules for using, selecting and modifying an option are identical to those
defined by Microsoft Windows.
Using the menus
To input a numerical value (time base, alignment, etc.), a double click on the
numerical field brings up a virtual keyboard:
Network Configuration of the "Network" interface (ETHERNET).
This interface uses the same connector (RS232/ETHERNET), located on the
right-hand side of the instrument, and requires a specific ETHERNET / RJ 45
cable.
General principles of
the ETHERNET
network
Addressing
ETHERNET and TCP/IP (Transmission Protocol/Internet Protocol) are used to
communicate on a company's network.
Each piece of equipment under TCP/IP has a physical address
(ETHERNET) and an Internet address (IP).
ETHERNET physical
addresses A physical or ETHERNET address, stored in ROM or PAL, identifies each
item of equipment on the network. The physical address enables the
equipment to determine the source of data "packet" transmission.
The physical address is a number coded over 6 bytes represented in
hexadecimal form. Hardware manufacturers procure physical addresses and
allocate them incrementally when the product is manufactured. The physical
addresses cannot be modified.
Numerical value being input
Pressing on one of these keys initialises
the input field with the min. or max. value
of the parameter
The window title indicates the adjustment
in process and the measurement unit
Erase
key
Exit the window, validating (or cancelling) the
value entered
Use the E key followed by an exponent to
indicate a power of 10

Description of the instrument

Description of the instrument (cont'd)
Network (cont’d)
IP addresses
An IP address is coded over 4 bytes, displayed in decimal format.
(#Example: 132.147.250.10). Each field may be coded between 0 and 255
and is separated by a decimal point.
Unlike the physical address, the IP address can be modified by the user.
You must ensure that the IP address is unique on your network. If an address
is duplicated, network operation becomes random.
The IP address is made up of two parts:
•the network identifier (Network ID) identifying a given physical network
•the host identifier (Host ID) identifying a specific item of equipment on the
same network.
There are 5 addressing classes. Only classes A, B and C are used to identify
the equipment.
See below:
Class A
0XXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX
Network ID Host ID
Class B
10XXXXXX XXXXXXXX XXXXXXXX XXXXXXXX
Network ID Host ID
Class C
010XXXXX XXXXXXXX XXXXXXXX XXXXXXXX
Network ID Host ID

SCOPIX Oscilloscopes II - 19
Description of the instrument (cont'd)
SUBNET mask
and GATEWAY If the result of the operation ' AND LOGICAL' between IP address of the
recipient of the message and the value of subnet mask is different from the
address of the recipient of the message, this message is sent to the
gateway which will be given the responsibility to forward it to destination.
The programming of the mask and the address of the gateway is possible
on the instrument, in the Advanced mode.
DHCP Protocol
This protocol is used to automatically assign an IP address to the
instrument when it connects up to the network.
A DHCP (Dynamic Host Configuration protocol) server must be accessible
on this network (contact your network administrator to make sure that this
server is present).
FTP protocol A file can be transferred quickly between a PC and the instrument using FTP
(File Transfer Protocol).
To use it, open the browser on the PC and, in the URL field, type the IP
address of the instrument, preceded by "ftp:"
#Example: ftp://192.168.3.1
The oscilloscope is an FTP server.
See §. Applications p. 176.
HTTP protocol The instrument integrating the 'HTTP server' protocol functions like a WEB
server and can be accessed from a PC using a standard browser (EXPLORER,
NETSCAPE, FIREBOX …). You can then reach the most current adjustments
and visualize traces on your PC.
To use it, open the browser on the PC and, in the URL field, type the IP
address of the instrument, preceded by "http:"
#Example: http://192.168.3.1
See §. Applications p. 174.
To be able to display the traces, you must install on your PC the Java Virtual
Machine JVM SUN 1.4.1 (or higher). This JVM can be downloaded from the
site http://java.sun.com
LPD protocol This protocol (Line Printer Daemon) is used by most of the printers
connected to an ETHERNET network, but also by the printing server units
which handle conversion between ETHERNET and CENTRONICS
(#Example: Jet Admin) and UNIX and LINUX workstations.
An LPD server can also be installed on a PC (available as an option with
WINDOWS 2000 or XP).
In all cases, the instrument is an LPD client which has to be configured to
indicate to it the IP address of the LPD server (the workstation PC or
directly the printer) and the logical name of the printer managed by the
server.
See §. Applications p. 180.
