1 Getting Started
Inspect the Package Contents
• Inspect the shipping container for damage.
If your shipping container appears to be damaged, keep the shipping container
or cushioning material until you have inspected the contents of the shipment
for completeness and have checked the oscilloscope mechanically and
electrically.
• Verify that you received the following items and any optional accessories you
may have ordered:
• InfiniiVision DSOX1204A/G oscilloscope.
• Power cord (country of origin determines specific type).
• Oscilloscope probes (one for each analog input channel).
12 Keysight InfiniiVision DSOX1204A/G Oscilloscopes User's Guide
Power-On the Oscilloscope
WARNING
Getting Started 1
Power
Requirements
Ventilation
Requirements
To powe r-on the
oscilloscope
Line voltage, frequency, and power:
• ~Line 100-120 Vac, 50/60/400 Hz
• 100-240 Vac, 50/60 Hz
•50W max
The air intake and exhaust areas must be free from obstructions. Unrestricted air
flow is required for proper cooling. Always ensure that the air intake and exhaust
areas are free from obstructions.
The fan draws air in from the left side and bottom of the oscilloscope and pushes it
out behind the oscilloscope.
When using the oscilloscope in a bench-top setting, provide at least 2" clearance
at the sides and 4" (100 mm) clearance above and behind the oscilloscope for
proper cooling.
1 Connect the power cord to the rear of the oscilloscope, then to a suitable AC
voltage source. Route the power cord so the oscilloscope's feet and legs do not
pinch the cord.
2 The oscilloscope automatically adjusts for input line voltages in the range 100
to 240 VAC. The line cord provided is matched to the country of origin.
Always use a grounded power cord. Do not defeat the power cord ground.
Keysight InfiniiVision DSOX1204A/G Oscilloscopes User's Guide 13
3 Press the power switch.
The power switch is located on the lower left corner of the front panel. The
oscilloscope will perform a self-test and will be operational in a few seconds.

WARNING
Connect Probes to the Oscilloscope
1 Connect the oscilloscope probe to an oscilloscope channel BNC connector.
2 Connect the probe's retractable hook tip to the point of interest on the circuit or
device under test. Be sure to connect the probe ground lead to a ground point
on the circuit.
Maximum input voltage at analog inputs
150 Vrms, 200 Vpk
Do not float the oscilloscope chassis
Defeating the ground connection and "floating" the oscilloscope chassis will probably
result in inaccurate measurements and may also cause equipment damage. The probe
ground lead is connected to the oscilloscope chassis and the ground wire in the power
cord. If you need to measure between two live points, use a differential probe with
sufficient dynamic range.
Do not negate the protective action of the ground connection to the oscilloscope. The
oscilloscope must remain grounded through its power cord. Defeating the ground
creates an electric shock hazard.
14 Keysight InfiniiVision DSOX1204A/G Oscilloscopes User's Guide
Input a Waveform
WARNING
The Probe Comp signal is used for compensating probes.
1 Connect an oscilloscope probe from channel 1 to the Demo, Probe Comp terminal
on the front panel.
2 Connect the probe's ground lead to the ground terminal (next to the Demo
terminal).
A voltage source should never be connected to the ground terminal of this instrument.
If, for any reason, the Protective Conductor Terminal is disconnected or not functioning
properly and a voltage source is connected to the equipment's ground terminals, the
entire chassis will be at the voltage potential of the voltage source, and the operator or
bystanders could receive an electric shock.

autoscaled, or preserve the acquisition mode during autoscale, press Fast
Debug, Channels, or Acq Mode.
These are the same softkeys that appear in the Autoscale Preferences menu.
See "Utility Settings" on page 87.
If you see the waveform, but the square wave is not shaped correctly as shown
above, perform the procedure "Compensate Passive Probes" on page 18.
If you do not see the waveform, make sure the probe is connected securely to the
front panel channel input BNC and to the Demo/Probe Comp terminal.

Compensate Passive Probes
Each oscilloscope passive probe must be compensated to match the input
characteristics of the oscilloscope channel to which it is connected. A poorly
compensated probe can introduce significant measurement errors.
If your probe has a configurable attenuation setting (like the N2140/42A probes do), the 10:1
setting must be used for probe compensation.
1 Input the Probe Comp signal (see "Input a Waveform" on page 15).
2 Press [Default Setup] to recall the default oscilloscope setup (see "Recall the
Default Oscilloscope Setup" on page 16).
3 Press [Auto Scale] to automatically configure the oscilloscope for the Probe
Comp signal (see "Use Autoscale" on page 17).
4 Press the channel key to which the probe is connected ([1], [2], etc.).
5 In the Channel Menu, press Probe.
6 In the Channel Probe Menu, press Probe Check; then, follow the instructions
on-screen.
18 Keysight InfiniiVision DSOX1204A/G Oscilloscopes User's Guide
If necessary, use a nonmetallic tool (supplied with the probe) to adjust the
trimmer capacitor on the probe for the flattest pulse possible.
On some probes (like the N2140/42A probes), the trimmer capacitor is located
on the probe BNC connector. On other probes (like the N2862/63/90 probes),
the trimmer capacitor is a yellow adjustment on the probe tip.
7 Connect probes to all other oscilloscope channels.

20. USB Host port This port is for connecting USB mass storage devices or printers to the oscilloscope.
On G-suffix models, the built-in waveform generator can output sine, square, ramp, pulse, DC, or
noise on the Gen Out BNC. Press the [Wave Gen] key to set up the waveform generator. See
"Waveform Generator" on page 75.
You can also send the trigger output signal or the mask test failure signal to the Gen Out BNC
connector. See "Utility Settings" on page 87.
• Demo terminal — This terminal outputs the Probe Comp signal which helps you match a probe's
input capacitance to the oscilloscope channel to which it is connected. See "Compensate
Passive Probes" on page 18. The oscilloscope can also output demo or training signals on this
terminal.
• Ground terminal — Use the ground terminal for oscilloscope probes connected to the Demo/Probe
Comp terminal. See the warning in "Input a Waveform" on page 15.
Connect a USB compliant mass storage device (flash drive, disk drive, etc.) to save or recall
oscilloscope setup files and reference waveforms or to save data and screen images. See
"Save/Recall (Setups, Screens, Data)" on page 82.
To print, connect a USB compliant printer. For more information about printing see "Print
(Screens)" on page 85.
You can also use the USB port to update the oscilloscope's system software when updates are
available.
NOTE: You must Eject a USB mass storage device before unplugging it; otherwise, the device will be
marked as needing repair when connecting to a computer with the Windows operating system (even
though there are no harmful effects to the device).
CAUTION:Do not connect a host computer to the oscilloscope's USB host port. A host computer
sees the oscilloscope as a device, so connect the host computer to the oscilloscope's device port (on
the rear panel). See "Learn the Rear Panel Connectors" on page 26.
Front Panel Overlays for Different Languages
Front panel overlays, which have translations for the English front panel keys and
label text, are available in many languages. The appropriate overlay is included
when the localization option is chosen at time of purchase.
To install a front panel overlay:
1 Gently pull on the front panel knobs to remove them.
2 Insert the overlay's side tabs into the slots on the front panel.
3 Reinstall the front panel knobs.
