Charging the battery
Charging the battery while using the oscilloscope
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 loading of the battery (after 15 min), the startup of the oscilloscope causes the premature stop of the load. It is possible to re­start the loading while disconnecting, then reconnecting the charger.
The LED goes out when the battery is fully charged (approx. 2h30).
When the oscilloscope is connected to the mains 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. five hours and a half. 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
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.
the battery is 60% charged, etc.
this symbol indicates that there are only a few minutes more, so you are advised to recharge it or switch to the mains supply.
The battery is totally flat and the screen is about to be deactivated. You must either recharge the battery or connect the instrument to the external power supply.

Network
General principles
of the ETHERNET
network
Addressing
ETHERNET physical
addresses
Configuration of the "Network" interface (ETHERNET). This interface uses the same connector (USB/RS232/ETHERNET), located on
the right-hand side of the instrument, and requires a specific ETHERNET / RJ 45 cable.
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).
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.
SCOPIX II - 19
Description of the instrument
Description of the instrument (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

SUBNET mask and GATEWAY
DHCP Protocol
FTP protocol
If the result of the operation ' ET LOGIQUE' 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.
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).
A file can be transferred quickly between a PC and the instrument using FTP (File Transfer Protocol). To use the "FTP Server" function, open your favourite browser on the PC (Firefox, Explorer 7, Chrome, ...) and type in the URL field: "ftp://192.168.3.1/RAM:" to access the internal file system of instrument IP address 192.168.3.1 "ftp://192.168.3.1/CARD:" to access the file system of instrument SDCARD IP address 192.168.3.1
The oscilloscope is can also be used as an FTP client.
See §. Applications p. 190.
HTTP protocol
LPD 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. 156.
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
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. ”Virtual Printers” can also be used for this purpose.
See §. Applications p. 189.

Formatting the
SD Card
A specific folder on the SD Card, called "metrix", is used for recording files by the oscilloscope.
From within the oscilloscope, the user can only act in this folder:
File creation,
File saving,
File deletion.
If, at the moment of file saving, the "metrix" folder does not exist, it is automatically created.
It is possible to insert or remove an SD Card from its compartment, even when the oscilloscope is running. Never remove a card while a file is being written on it. Doing so can cause the file save operation to fail, and even
damage the memory card.
If a window displaying the memory was open during card insertion/removal, it is recommended to close it, then to open it again to update the display.
The SD Card is formatted using a PC. It cannot be formatted via the oscilloscope.

Distribution of stray capacitances:
It is essential, given the stray capacitances, to connect properly the reference conductors for each probe. These conductors should preferably be connected to the cold points, to prevent the transmission of noise by the stray capacitance between modes.
The noise of the digital earth is transmitted to the analog input by the stray
capacitance.
To prevent electric shocks or possible fire, never use the “earthing spring” accessory of the 1/10 probe for voltages > 30Vrms in relation to ground.

Vpp(ch1) = Vpp(ch2) = 6 V
Sensitivity (ch1) = 1 V/div
Sensitivity (ch2) = 1 V/div
Vertical scale math3 = 2.00 div Vpp math3 = 12.00 div Vhigh math3 = 6.00 div
There is a high and low overshoot, so division by 2 is necessary to optimize display of the result.

Sensitivity(ch2) = 5 V/div
Vamp(ch1) = Vamp(ch2) = 10 V
As for the addition of traces, there is a even more significant high and low overshoot.
The overshoot is due to the increased dynamics of the numbers after a multiplication ; to avoid this and standardize the result, use the divv () function.
Example
following function is used to get an amplitude of 1 divv :
math3 = (ch1 * ch2) / divv (1)
The result of the multiplication is translated into divisions on the screen.
: If Amplitude on CH1 = 2 divv and Amplitude on CH2 = 2 divv, the
- If Vamp ch1 = 8 div and Vamp ch2 = 8 div, the result
must be divided by divv(4) to obtain Vamp math3 = 4 div.
- When mathematical functions associated with traces are used, the dynamics of the result obtained must be verified.
Correction of the result of the operations by mathematical functions (divv(), divh(), / …) is recommended to optimize the screen display.

FFT (Fast Fourier

Description
The Fast Fourier Transform (FFT) is used for calculating the discrete
representation of a signal in a frequency domain from its discrete representation in the time domain.
FFT can be used in the following applications:
measurement of the different harmonics and the distortion of a signal,
analysis of a pulse response,
search for noise source in logic circuits.
The FFT is calculated over 2500 points.
The Fast Fourier Transform is selected by the FFT icon in the control area. When the trace is zoomed, the FFT applies to the zoomed part of the trace
(next to the time base adjustment).
The Fast Fourier Transform is calculated using the equation:
N

X (k) =
with: x (n): a sample in the time domain X (k): a sample in the frequency domain N: resolution of the FFT n: time index k: frequency index
The displayed trace represents the amplitude in V or dB of the various signal
frequency components according to the scale selected (linear or logarithmic).
