Description of the instrument

Presentation

The particularity of these oscilloscopes is that they group 3 instruments in

one:

Digital

oscilloscope

Multimeter

OX 5022
OX 504

Harmonic

analyser

• a laboratory digital oscilloscope for the analysis of electronic and

electrotechnical signals,

• a 2-channel, 8000-count multimeter,

• a harmonic analyser, for the simultaneous decomposition

of 2 signals with their fundamental and their first 31 harmonics.

The instrument operates at a constant acquisition depth of 2,500 points.

Power supply

An LCD TFT screen is used to view the applied signals along with all the
setting parameters.

The main command functions are accessible using the keys on the front
panel.

A graphic interface is used to:

- adjust the parameters related to the selected button,

- navigate using a horizontal main menu showing the current settings and
vertical sub-menus.

The oscilloscope is delivered with:

• one external power supply Æ Voltage: 12 VDC

Power: 1.25 A

Polarity:

• 6 rechargeable Æ Ni-MH (1.2 V, 2700 mAh) accumulator batteries.

When the external power supply is connected, this power source is preferred
for the instrument's operation. Thus the accumulators are only used when
there is no external power supply.

*

With the external power supply you can use your oscilloscope even if
the batteries are flat, defective or even absent.

Description of the instrument (cont’d)

Batteries

Charge

A "battery empty" indicator appears on the screen when the accumulator­battery charge level is insufficient and a new power source is needed
quickly:

• connect the external power supply or

• change the batteries.

If the external power supplied is not connected when the level becomes

critical, an alarm message "Battery level is critical, the appliance is
about to power off" precedes the automatic shutdown of the instrument.

The batteries are charged when the oscilloscope is powered off but
connected to the external power supply.
During the fast charge of the batteries, the front-panel LED is on.

It flashes in the following situations:

• pre-charge of very flat batteries

• temperature too low or too high

• batteries damaged.

When the charge is complete the LED switches off. The batteries must be
replaced with Ni-MH rechargeable batteries. Battery charge life is
guaranteed for same-capacity batteries (in mAh) as those shipped with the
oscilloscope.

*

Access

It is possible, but not recommended, to use standard alkaline batteries
(AA type) to replace the accumulators, but in this case be careful:

• not to connect the external power supply because when the

instrument is switched off the charge mechanism is activated which
can lead to destruction of the batteries and damage to the
instrument;

• not to leave the batteries in the instrument for too long to avoid

any problems caused by leakage from the batteries.

If necessary, the batteries(1) are accessible from the rear panel of the
oscilloscope after turning the "quarter turn" (2) lock anti-clockwise; use a
coin (3):

Channel insulation

The two oscilloscope input channels are insulated from each other and from
the earth and the mains power supply block. This insulation is double or
reinforced in compliance with the safety standards
IEC 61010-1 and IEC 61010-2-030.

This makes it possible to make measurements on installations or systems
connected to the electricity supply network for voltages of up to 600 V in
CAT III. The common mode authorised between the two channels is 600 V
in CAT III.

Thus the operator, the test systems and the environment are completely
protected at all times.

Any voltage (even dangerous) on one channel will not be present on the
other channel. The low points of the inputs are completely insulated, so there
is no possibility of the low points looping (which can be dangerous and highly
destructive).

The oscilloscope insulation is as shown in the diagram below:

*

The use of accessories with a voltage and/or category lower than 600 V
CAT III reduces the operating range to the lower voltages and/or
categories.

Your oscilloscope is rated 600 V CAT III; at least 600 V CAT III
accessories must be used. The accessories shipped with the instrument
allow this.

Advice for use of the sensors

Connection of the

reference

conductors to the

sensor

Distribution of stray capacitors:

It is imperative, considering the stray capacitances, to correctly connect the
reference conductors for each sensor. The conductors should preferably be
connected to the cold points to avoid the transmission of noise by the stray
capacitance between modes.

Reminder In order to prevent electric shocks or possible fires:

Reminder See p. 4 Input connection and disconnection instructions.

The noise of the digital ground (earth) is sent to the analogue input by the

stray capacitance

Never use accessories on which the casing

is accessible if it has a voltage of > 30 Vrms
compared to the earth.

This precaution is necessary for example for sensors with an
accessible metal BNC. The accessories shipped with the instrument
are compliant.

Sensor calibration

The calibration output (3 Vpp, 1 kHz) for the sensors is underneath the
battery cover (see p. 10).

To obtain optimum response, the sensor's low frequency compensation must
be adjusted. To carry out this adjustment, the two channels of your
oscilloscope must be disconnected from the measured circuits before
opening the battery housing cover.

Select the DC coupling for the channel to which the sensor is connected and
run an autoset (icon opposite) to carry out pre-setting. Adjust the sensitivity
and the vertical offset of the channel so that the signal fills the screen, and
adjust the time base to 200 µs to view a signal period on the screen. Turn the
BNC base of the sensor in order to access the sensor adjustment screw:

Connect the sensor to be
adjusted to the calibration
output under the battery housing
cover, as shown opposite.

In the example opposite the
sensor is over-compensated:
an overshoot occurs.

Turn the screw in either direction
until the signal is horizontal and
looks like the screen shown
opposite. Your sensor is now
calibrated, so you can turn the
BNC base again to close access
to the adjustment screw.

*

Replace the battery cover in order to use your instrument in optimum safety
conditions.

1. Mathematical
functions

Warning, the calculation of the mathematical functions is not carried out on
physical quantities, but on the signal samples. Be careful in particular to use
identical sensitivities on channels A and B for addition and subtraction so
that the calculation is meaningful.

Thus, the sensitivity of the Math channel is determined as follows:

Operation

- A X - X

- B - Y Y

A + B X

A - B X

A * B X Y XY

A / B X Y X / Y

Sensitivity

In our example the amplitude of the resulting signal is 10 Vpp. As the
sensitivity of channel M is 1 Vpp, it can be seen that the trace overshoots
but is contained on the screen by dividing the representation by 2:

Example 2

M = A * B, multiplication of a 5 Vpp sine and square almost in phase:

The sensitivity of the M
channel becomes 2 V
and the amplitude
remains at 10 Vpp.

In our example, the peak
amplitude of our
mathematical function is

2.5 V * 2.5 V = 6.25 VV.
As the channel M
sensitivity is 1 VV (with
the factor x 1), it can be
seen that the trace
overshoots and can be
corrected by using the /2
coefficient.

2 VV and the peak

Example 3

M = A / B, division of a 5 Vpp sine and square almost in phase:

As the positive voltages of signals A and B are equal, the division leads to a
positive peak voltage of 1 V/V, and therefore a representation of 1 division
on the trace. This can be expanded by choosing factor x 2 or x 5:

The sensitivity of channel M changes to 500 mV/V and the positive peak

amplitude of the trace is 1 V/V.

Remote programming

Presentation

Connecting the oscilloscope

The oscilloscope can be programmed remotely from a computer:

• either using the SX-METRO software,

• or using basic standardised commands that comply with the

IEEE488.2 standard and the SCPI protocol.

This remote programming is used to:

• Configure the instrument

• Perform measurements and retrieve the results

• Transfer files (traces, configuration, screenshots, etc.)

Here we will only describe the connection of the oscilloscope to
SX-METRO. For all other use, refer to the remote programming
instructions.

The dialogue between the instrument and the PC is carried out via the
USB/optical link provided by the HX0056-Z cable.

• Connect the USB end of the cable to one of the PC USB ports
(if necessary install the driver shipped with the cable).

• Connect the optical connector to the oscilloscope after first powering it
up.

• Open SX-METRO; select USB communications and wait for
communications to be established (in the event of a problem, refer to
the SX-METRO instructions).
