Fuse

Starting up

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 an Ni-MH battery (9.6V, 3.5Ah).

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 centre.

• 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 on and then a clock is displayed on
the screen during the start-up sequence.

The message "Instrument start-up" is displayed.

The oscilloscope contains a Ni-MH 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 centre.

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

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

Insertion/Extraction

Operation

The internal memory of the oscilloscope (2MB) may be extended by using
an SD Card (128MB - 2GB).

The oscilloscope accepts the Micro-SD format (but not Micro-SDHC).

FAT32 format is not compatible with the oscilloscope.

The SD Card compartment is located on the right-hand side of the
oscilloscope near the communications interface connector.

- Insert the SD Card, in the card compartment, printed surface facing up.

- Push to the click Æ the card is in position.

- To remove the card, press slightly on the card itself and support it while

removing.

Recording

a file

• The filename is limited to a maximum of 20 characters + extension.
If this rule is not observed, the message: 'Filename too long’ is displayed.

• If the name already exists or is incompatible, an error message
‘Impossible! File already exists' will be displayed.

• By moving the pointer

onto the names of the files, you will see their

characteristics displayed (date and time saved and size).

Special folder

"Hot Plugging"

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.

Description of Accessories

Concept The portable oscilloscopes in this range use Probix intelligent probes and

adapters, offering users active safety.

When connected to an oscilloscope input, a safety message in English
concerning the probe or adapter used indicates:

• its maximum input voltage according to the category

• its maximum voltage in relation to the earth, according to the category

• its maximum voltage between channels, according to the category

• its type

• its basic specifications

• the use of suitable safety leads.

* For user and instrument safety, this information must be respected.

Some probes are equipped with buttons whose assignment can be
programmed.

The color of the signal measured with a particular accessory is
parameterized in the "Green" Æ "chX" Æ "Probix" menu. An
interchangeable elastic band or plastic ID markers can be used to match the
probe color to the curve color.

The scaling and the units are managed automatically by the Probix system, thus
allowing fast measurements and without risk of error.

The oscilloscope provides the power supply for the probes and adapters.

Recommendations for use: see p. 39.

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.

• Predefined divv() function used on its own: math3 = divv(3).

The trace is equal to 3 vertical divisions.

• Predefined step() function associated with a trace:

- math2 = ch1*step(t-divh(4))

The result of math2 is 0 vertical divisions as long as t is less than

four horizontal divisions (t-divh(4) < 0).

The result of math2 is equal to ch1 when t becomes greater than

four horizontal divisions (t-divh(4) > 0).

- math2 = ch1*step(divh(4)-t)

The result of math2 is equal to ch1 as long as t is less than four

horizontal divisions (t-divh(4) > 0).

Example 1

Addition of two

traces

Traces ch1 and ch2 are optimized on 6 vertical divisions.

Vamp ch1 = 6 vertical divisions
Vamp ch2 = 6 vertical divisions

- math3 = ch1+ch2

Vhigh

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.

- math3 = (ch1+ch2) / 2

Vertical scale math3 = 2.00 div
Vpp math3 = 12.00 div
Vhigh math3 = 6.00 div

Division by two adjusts the addition to the dynamics of the screen.

Vamp math3 = 6 vertical divisions

The measuring unit and the sensitivity of ch1 are used during the

display of measurements.

You can then open the menu “Vertical Scale" of math3 (see §. Opening
from math3, math4) to assign a coefficient to the result and to modify
the measuring unit.

Example 2

Multiplication of two

traces

Oscilloscope Mode - The "Vertical" Menu

Sensitivity(ch1) = 5 V/div

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

−

1

2

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).

The DC component of the signal is removed by software.

The finite duration of the study interval results in a convolution in the signal
frequency domain with a function sinx/x.

This convolution modifies the graphic representation of the FFT because
of the lateral lobes characteristic of the sinx/x function (unless the study
interval contains an whole number of periods).

Effects of under-sampling on frequency representation:
If the sampling frequency is not correctly adjusted (less than or twice the

components will be under-sampled and appear in the graphic
representation of the FFT by symmetry (aliasing).
