HDO9000 Getting Started Guide
5
To achieve optimal signal integrity, connect the ground at the tip of the flying
lead for each channel used in measurements. Use either the provided ground
extenders or flying ground leads to
make the ground connection.
To connect the leadset to the
oscilloscope, push the connector
into the mixed signal interface until
you hear a click.
To remove the leadset, press in and
hold the buttons on each side of the
connector, then pull out to release it.
Powering On/Off
Plug the line cord only into a grounded AC power outlet. See Power in
“Safety” for ratings.
Press the
Power button
to turn on the oscilloscope. The
button will light to show the oscilloscope is operational.
CAUTION.
Do not power on or calibrate with a signal attached.
Press the Power button again or use or the
File > Shutdown
menu option
to execute a proper shut down process and preserve settings.
CAUTION
. Do not press and hold the Power button. This will
execute a hard shutdown, but may not preserve setups and data.
The Power button does not disconnect the oscilloscope from the AC
power supply, but puts it into "Standby" mode. Some “housekeeping”
circuitry continues to draw power. The only way to fully power down the
instrument is unplug the AC line cord from the outlet. We recommend
unplugging the instrument if it will remain unused for a long period of time
CAUTION.
Do not change the Windows® Power setting to System
Standby or System Hibernate. Doing so may cause failure.
OVERVIEW
The
touch screen display
is the principal viewing and control center of
the oscilloscope. See p.10 for an overview of its components.
The
front panel
houses hard controls for different acquisition settings.
Operate the instrument using front panel controls, touch screen controls,
or a mix that is convenient for you. See "Front Panel" on p.9.
Channels 1–4
are used to input analog signal.
EXT
can be used to input
an external trigger signal.
AUX out
can be configured to send a pulse to another device upon a
trigger event or Pass/Fail outcome.
The
LBUS port
may be used with the optional 8-Channel Sync to provide
precise synchonization with other instruments, or the HDA125-xx-LBUS
for high-speed digital analysis and triggering.
Cal out
emits a signal that can be used to compensate passive probes.
HDO9000 oscilloscopes are compatible with the included passive probes
and all ProBus active probes that are rated for the oscilloscope’s bandwidth.
Probe specifications and documentation are at
teledynelecroy.com/probes
.
Supplied with the Mixed Signal
models, the digital leadset connects
to the
Mixed Signal interface
to
input up-to-16 lines of digital data.
Two digital banks with separate
threshold and hysteresis controls
make it possible to simultaneously
view data from different logic
families. Each flying lead has a
signal and a ground connection. A
variety of ground extenders and
flying ground leads are available for
your probing needs.
