Presentation

The adjustment of the 2 ways is accessible by the opposite keys. This instrument is part of our range of portable oscilloscopes.

Its special feature is that it groups 2 instruments into one (OX 6062 and OX 6152 only) :

OX 6062 and OX 6152 only : an 4,000-count multimeter. Caution : “measurement ground is connected to earth ground".

The instrument works with a constant acquisition depth of 2500 counts. Memory management is organized using a "Windows®"-type file system. A large colour (or monochrome OX 6062-M) LCD screen is used to view the

signals applied, along with all the settings. The main control functions are directly accessible using the keys on the front

panel and can be modified using a touch-sensitive pad with the stylus supplied.

A graphical interface similar to a PC's is used to:

•

select the advanced functions by means of drop-down menus and the

touch-sensitive pad

•

act directly on the objects (curves, cursors, etc.) displayed on the screen. This means that the settings can be modified. This instrument is completed by RS232, ETHERNET and CENTRONICS

communication interfaces (option).

Starting up

•

The oscilloscopes are designed to operate on a power source delivering

90 to 264 V (ACrms) at 50 to 60 Hz.

• Take the power cord which is in the trunk (p. 9). The power supply can remain in the trunk.

• Connect the power cord to the mains.

• 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 is then ready for use.

By default, the "Advanced" mode is not active

Network

General principles of

the ETHERNET

network

Addressing

ETHERNET physical

addresses

IP addresses

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.

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.

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).

FTP (File Transfer Protocol) is used in the oscilloscope for fast file transfers to or from a PC.

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. 87 and 82.

HTTP protocol

LPD protocol

With this protocol, the instrument can act as a WEB server and you can access the most frequent settings and view traces on your PC using your browser (EXPLORER, NETSCAPE, …)

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. 84.

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 dowloaded 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.

See §. Applications p. 83.

As for the addition of traces, there is an even more significant high and low overshoot. The overshoot is due to the increase in dynamics of the numbers after a multiplication; to avoid this and standardize the result, the vertical scale adapts.

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.



Description

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.

The Fast Fourier Transform is calculated using the equation:

−

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).
