Precautions

 Use proper power cord. Use only the power cord shipped with this

instrument and certified for the country of use.

 Maintain ground. This product is grounded through the power cord

grounding conductor. To avoid electric shock, connect only to a
grounded mating outlet.

 Connect and disconnect properly. Do not connect/disconnect probes or

test leads while they are connected to a voltage source.

 Observe all terminal ratings. Do not apply a voltage to any input (C1,

C2, C3, C4 or EXT) that exceeds the maximum rating of that input. Refer
to the front of the oscilloscope for maximum input ratings.

 Use only within operational environment listed. Do not use in wet or

explosive atmospheres.

 Use indoors only.
 Keep product surfaces clean and dry.
 Do not block the cooling vents. Leave a minimum six-inch (15 cm) gap

between the instrument and the nearest object. Keep the underside
clear of papers and other objects.

 Do not remove the covers or inside parts. Refer all maintenance to

qualified service personnel.

 Do not operate with suspected failures. Do not use the product if any

part is damaged. Obviously incorrect measurement behaviors (such as
failure to calibrate) might indicate impairment due to hazardous live
electrical quantities. Cease operation immediately and sequester the
instrument from inadvertent use.

Operator’s Manual

922131-00 Rev A 5

Operating Environment

Temperature: 10 to 40 °C.

Humidity: Maximum relative humidity 80 % for temperatures up to 31 °C

decreasing linearly to 50 % relative humidity at 40 °C (or at the upper
operational temperature limit).

Altitude: Up to 10,000 ft (3,048 m) at or below 25 °C.

Note: Direct sunlight, radiators, and other heat sources should be taken into

account when assessing the ambient temperature.

Cooling

The instrument relies on forced air cooling with internal fans and vents. Take
care to avoid restricting the airflow to any part of the oscilloscope. Around the
sides and rear, leave a minimum of 15 cm (6 inches) between the instrument
and the nearest object. At the bottom, the oscilloscope feet (up or down)
provide adequate clearance.

CAUTION. Do not block oscilloscope vents. Always keep the area
beneath the oscilloscope clear of paper and other items.

The instrument also has internal fan control circuitry that regulates
the fan speed based on the ambient temperature. This is performed
automatically after start-up.

Cleaning

Clean only the exterior of the oscilloscope using a damp, soft cloth. Do not use
harsh chemicals or abrasive elements. Under no circumstances submerge the
instrument or allow moisture to penetrate it. Avoid electric shock by
unplugging the power cord from the AC outlet before cleaning.

CAUTION. Do not attempt to clean internal parts. Refer to qualified
service personnel.

Power Consumption

< 50 Watts for all models (depending on accessories installed - probes, USB
devices, etc.).

Power consumption in Standby Mode: < 5 Watts.

Power and Ground Connections

The instrument is provided with a 10A/250V 18AWG rated grounded cord set
containing a molded three-terminal polarized plug and a standard IEC-60320
(Type C13) connector for making line voltage and safety ground connections.

The AC inlet ground is connected directly to the frame of the instrument. For
adequate protection again electric shock, connect to a mating outlet with a
safety ground contact.

WARNING. Interrupting the protective conductor inside or outside
the oscilloscope, or disconnecting the safety ground terminal, creates
a hazardous situation. Intentional interruption is prohibited.

Standby Power

The Power (Standby) button controls the operational state of the
oscilloscope. Press the button to switch the instrument On or into Standby
mode (Off).

Always use the Power button to execute a proper shut down process and
preserve settings before powering down.

Powering off does not disconnect the oscilloscope from the AC power supply.
The only way to fully power down the instrument is to shut down then unplug
the AC power cord from the outlet.

We recommend unplugging the instrument if it will be unused for a long
period of time.

You can choose one of these input coupling modes:

 DC - Passes both AC and DC components of the input signal.
 AC - Blocks the DC component of the input signal and attenuates signals

below 10 Hz.

 GND - Disconnects the input signal. Use GND coupling to display a zero-

volt waveform. Internally, the channel input is connected to a zero-volt
reference level.

NOTE:

 If the channel is set to DC coupling, you can quickly measure the DC

component of the signal by simply noting its distance from the ground
symbol.

 If the channel is set to AC coupling, the DC component of the signal is

blocked allowing you to use greater sensitivity to display the AC
component of the symbol.

1. Choose an input coupling mode. Turn on the desired channel by

pressing the appropriate channel button - CH1 or CH2 (or CH3 or 4 on 4
channel models).

2. Now, press the Coupling option button on page 1/2 of the channel

menu, and then select a coupling mode from the menu.

Limiting Bandwidth

You can limit the bandwidth to reduce display noise. When you turn
Bandwidth Limit ON, the Bandwidth Limit value is set to 20 MHz. It also filters
the signal to reduce noise and other unwanted high frequency components.

NOTE: The oscilloscope vertical response rolls off slowly above its bandwidth;
or, above 20 MHz when the Bandwidth Limit is set to ON. Therefore, the FFT
spectrum can show valid frequency information higher than the oscilloscope
bandwidth. However, the magnitude information near or above the
bandwidth will not be accurate.

1. Turn the Bandwidth Limit ON by activating the specific channel. Press

the desired channel button - CH1 or CH2 (or CH3 or 4 on 4 channel
models).

2. Now, press the BW Limit option button on page 1/2 of the channel

menu, and then select On.

A highlighted B icon at the lower-left of the display indicates bandwidth
limitation is on.
