Installation
Power Cord Use only the power cord provided with your oscilloscope. Appendix C:
Accessories lists the standard and the optional accessories.
Power Source Use a power source that delivers 90 to 264 VACRMS,45to66Hz.Ifyouhavea
400 Hz power source, it must deliver 90 to 132 VACRMS, 360 to 440 Hz.
The product's maximum power consumption is 30 W.
Security Loop Use a standard laptop computer security lock, or thread a security cable through
the built-in cable channel to secure your oscilloscope to your location.

Functional Check
Perform this functional check to verify that your oscilloscope is operating
correctly.
ON/OFF button
1. Power on the oscilloscope.
Push the Default Setup button.
The default Probe option attenuation setting is
10X.
Default Setup button
PROBE COMP
2. Connect the TPP0051, TPP0101, or TP0201
probe to channel 1 on the oscilloscope. To do this,
align the slot in the probe connector with the key
on the channel 1 BNC, push to connect, and twist
to the right to lock the probe in place.
Connect the probe tip and reference lead to the
PROBE COMP terminals.
3. Push the Autoset button. Within a few seconds,
you should see a square wave in the display of
about 5 V peak-to-peak at 1 kHz.
Push the channel 1menu button on the front panel
twice to remove channel 1, push the channel
2menu button to display channel 2, and repeat
steps 2 and 3.
Calibration: PASSED 4. Check that the instruction passed the calibration
tests. Push Utility ►- more - page 1 of 2 (push

Ventilation NOTE. The oscilloscope cools by convection. Keep two inches clear on the sides
and top of the product to allow adequate air flow.

Probe Safety
Check and observe probe ratings before using probes.
A guard around the TPP0051, TPP0101, or TPP0201 probe body provides a finger
barrier for protection from electric shock.
Finger guard
WARNING. To avoid electric shock when using the probe, keep fingers behind
the guard on the probe body.
To avoid electric shock while using the probe, do not touch metallic portions of
the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope, and connect the ground terminal to ground
before you take any measurements.

Manual Probe Compensation
You can manually perform this adjustment to match your probe to the input
channel.
PROBE COMP Autoset
button
1. Push the 1►Probe ►Voltage ►Attenuation
option and select 10X. Connect the appropriate
TPP0051, TPP0101, or TPP0201 probe to
channel 1 on the oscilloscope. If you use the
probe hook-tip, ensure a proper connection by
firmly inserting the tip onto the probe.
2. Attach the probe tip to the PROBE COMP
~5V@1kHz terminal and the reference lead to
the PROBE COMP chassis terminal. Display the
channel, and then push the Autoset button.
Overcompensated
Undercompensated
Compensated correctly
3. Check the shape of the displayed waveform.
4. If necessary, adjust your probe.
Repeat as necessary.
Probe Attenuation Setting
Probes are available with various attenuation factors which affect the vertical
scale of the signal.
Select the factor that matches the attenuation of your probe. For example, to
match a probe set to 10X connected to CH 1, push the 1►Probe ►Volt age ►
Attenuation option, and select 10X.
NOTE. The default setting for the Attenuation option is 10X.

Electronics Katrangi Trading

Getting Started
If you change the Attenuation switch on a P2220 probe, you also need to change
the oscilloscope Attenuation option to match. Switch settings are 1X and 10X.
Attenuation switch
NOTE. When the Attenuation switch is set to 1X, the P2220 probe limits the
bandwidth of the oscilloscope to 6 MHz. To use the full bandwidth of the
oscilloscope, be sure to set the switch to 10X.
Current Probe Scaling
Current probes provide a voltage signal proportional to the current. You need to
set the oscilloscope to match the scale of your current probe. The default scale is
10 A/V.
For example, to set the scale for a current probe connected to channel 1, push the
1►Probe►Current ►Scale option, and select an appropriate value.
Self Calibration
The self calibration routine lets you optimize the oscilloscope signal path for
maximum measurement accuracy. You can run the routine at any time but you
should always run the routine if the ambient temperature changes by 5 °C (9 °F)
or more. The routine takes about two minutes.
For accurate calibration, power on the oscilloscope and wait twenty minutes to
ensure it is warmed up.
To compensate the signal path, disconnect any probes or cables from the input
connectors. Then, access the Utility ►Do Self Cal option, and follow the
directions on the screen.

Operating Basics
The front panel is divided into easy-to-use functional areas. This chapter provides
you with a quick overview of the controls and the information displayed on the
screen.
Display Area
In addition to displaying waveforms, the display provides details about the
waveform and the oscilloscope control settings.
NOTE. For details on displaying the FFT function, (See page 53, Displaying
the FFT Spectrum.)
The items shown below may appear in the display. Not all of these items are
visible at any given time. Some readouts move outside the graticule area when
menus are turned off.

Operating Basics
1. The acquisition readout shows when an acquisition is running or stopped.
Icons are:
Run: Acquisition enabled
Stop: Acquisitions not enabled.
2. The trigger position icon shows the trigger position in the acquisition. Turn
the Horizontal Position knob to adjust the position of the marker.
3. The trigger status readout shows:
Armed: The oscilloscope is acquiring pretrigger data. All triggers are ignored
in this state.
Ready: All pretrigger data has been acquired and the oscilloscope is ready to
accept a trigger.
Trig’d: The oscilloscope has seen a trigger and is acquiring the posttrigger
data.
Stop: The oscilloscope has stopped acquiring waveform data.
Acq. Complete: The oscilloscope has completed a Single Sequence
acquisition.
Auto: The oscilloscope is in auto mode and is acquiring waveforms in the
absence of trigger.
Scan: The oscilloscope is acquiring and displaying waveform data
continuously in scan mode.
4. The center graticule readout shows the time at the center graticule. The
trigger time is zero.
5. The trigger level icon shows the Edge or Pulse Width trigger level on the
waveform. The icon color corresponds to the trigger source color.
