Operating Safely with
Battery Power
WARNING. To avoid electric shock, always connect the rear-panel ground
terminal to earth ground when operating the instrument from battery power.
For safe operation, the oscilloscope chassis must remain at earth ground potential
even when operating from battery power. Without a connection between the
chassis and earth ground, you can receive a shock from exposed metal on the
chassis if you connect an input to a hazardous voltage (>30 VRMS, >42 Vpk). To
protect against this condition, attach the Tektronix-supplied grounding wire from
the terminal on the rear panel to earth ground. If you use a different grounding
wire, it must be larger than 18 gauge (1 mm2).
When you start to use the battery pack, an on-screen message reminds you to
connect the grounding wire between the ground terminal on the rear panel and
earth ground.

Main Board
The Main Board module contains the following functions.
3- 2
Acquisition System
The acquisition system begins with the analog signal path and ends with a
digitized signal in memory. The signal enters a channel input and then passes
through an attenuator and preamplifier. The analog signal from each preamplifier
goes through a sampler and digitizer, a time base controller, and then into
acquisition memory. The analog signal from each preamplifier is also distributed
to a trigger circuit.
Trigger System
The trigger system processes the analog signals from the preamplifiers and sends
trigger information to the time base controller. Advanced trigger functions are
enabled only when the appropriate application modules and supporting software
is installed.
Display System
The display system combines live waveform data from acquisition memory with
menus and text and stores this information in display memory. It then uses this
data to refresh the VGA display module (LCD).
TDS3000B Series Service Manual
Theory of Operation
Processor System
Power Converter
The processor system contains a MPC680DC Power PC microprocessor that
controls the entire instrument. The processor system also contains FLASH
ROM, system RAM, and interfaces to communication modules, the parallel
printer port, and the floppy disk drive.
The power converter receives 15 VDC (or battery voltage) from the battery board
and generates voltages for the analog and digital circuitry on the main board.
Display Module
The display module consists of a color liquid crystal display (LCD), a display
driver, a pair of fluorescent back light tubes, and a high-voltage back light power
supply.
Front-Panel Board
The front-panel board contains a microprocessor that reads the front-panel
buttons and controls and then sends this information to the processor system.
The front-panel board also generates the probe compensation output signal and
provides an interface to the application modules.
Disk Drive
The disk drive module consists of a 3.5 inch, IBM format, floppy disk drive. The
disk drive is controlled by circuitry on the Main Board.

Performance Verification
Performance Verification Procedures
The following three conditions must be met prior to doing these procedures:
1. The oscilloscope must have been operating continuously for twenty (20)
minutes in an environment the meets the operating range specifications for
temperature and humidity.
2. You must perform the Compensate Signal Path operation described on
page 2--22. If the operating temperature changes by more than 10° C, you
must perform the Compensate Signal Path operation again.
3. You must connect the oscilloscope and the test equipment to the same AC
power circuit. Connect the oscilloscope and test instruments into a common
power strip if you are unsure of the AC power circuit distribution. Connecting the oscilloscope and test instruments into separate AC power circuits can
result in offset voltages between the equipment, which can invalidate the
performance verification procedure.
The time required to complete the entire procedure is approximately one hour.
WARNING. Some procedures use hazardous voltages. To prevent electrical shock,
always set voltage source outputs to 0 V before making or changing any
interconnections.
Self Test
This procedure uses internal routines to verify that the oscilloscope functions and
passes its internal self tests. No test equipment or hookups are required. Start the
self test with these steps:
1. Disconnect all probes and cables from the oscilloscope inputs.
2. Push the UTILITY menu button.
3. Push the System screen button to select Diags.
4. Push the Loop screen button and choose Once.
5. Push the Execute screen button.
6. Push the OK Confirm Run Test screen button.

The number required is reduced by two if you are adjusting a two-channel oscilloscope.
Overview of the Adjustment Process
The oscilloscope is protected from inadvertently changing factory adjustments
by a rear-panel switch. To perform the factory adjustment, you must push and
hold the switch while you power on the oscilloscope.
Before performing adjustment procedures, you must warm up the oscilloscope at
least ten minutes in an ambient temperature between 20° C and 30° C. Adjustments performed prior to warm-up or outside this temperature range may result
in poor performance. You must also recall the default factory settings before
starting the factory adjustment procedure.
The factory adjustment procedure consists of a series of steps; as you move
through these steps, the oscilloscope display provides instructions that describe
the specific input signal requirements for each step. If the the step passes, the
oscilloscope moves on to the next step. If any step fails, you can repeat the step
or choose to abort the procedure.
NOTE. Do not turn any knobs or push any front-panel buttons other than the
Next Step or Previous Step buttons during the adjustment procedure. Doing so
will cause the oscilloscope to abort the adjustment procedure. The oscilloscope
uses the previous calibration constants if the adjustment procedure is aborted.
The screen does not display the actual oscilloscope settings (such as channel
input impedance, vertical and horizontal settings, and so on) during the
adjustment procedure. The oscilloscope automatically sets the instrument
settings, but these settings may not read out correctly on the display.
During some steps, the instrument may appear to be idle for several minutes
while it is processing information internally. Please have patience.
If all steps in the procedure are completed successfully, a “Pass” message is
displayed and the new calibration constants take affect. If the procedure fails for
any reason, the oscilloscope reverts to the previous calibration settings.

Adjustment Procedures
Signal Connections
The adjustment procedure requires three types of equipment setups if you are
adjusting a four-channel oscilloscope, or four types if you are adjusting a
two-channel oscilloscope. For each step of the procedure, the oscilloscope
display indicates which setup is the correct one to use. The equipment setups are
described below.
Applying DC Voltage to
Input Channels
The first adjustment procedures require a DC voltage (or zero volts) applied
simultaneously to all instrument channels. A typical on-screen instruction might
read:
Apply 0.0000 V DC signal to all channels.
When you see an instruction similar to this, connect the oscilloscope to the DC
voltage source to all the channels as shown below and then set the DC voltage to
the specified value.

Adjustment Procedures
NOTE. If the DC voltage source you are using has an output head, use a
female-to-female BNC adapter and a short BNC cable to make the connection to
the first BNC tee.
A number of steps require setting the input voltage to 0.0000 V. Some calibration
equipment can inject a small amount of noise or have a very low-level AC signal
near ground. This can result in failure of the performance verification procedure
even though the instrument passes the factory adjustment procedure. If you think
that your calibration equipment injects noise or AC at zero volts, make sure to
disconnect signal cables from the oscilloscope for all steps that require 0.000 V
input.
Applying AC Voltage to a
Channel
Later in the procedure, a leveled sine wave needs to be applied to each channel,
one channel at a time. A typical on-screen instruction might read:
Apply 400.00 mV Pk-Pk 80 MHz sine wave signal to
channel 1 only.
When you see an instruction similar to this, connect the leveled sine wave
generator to the specified channel and then set the amplitude and frequency to
the specified values.

NOTE. If the leveled sine wave generator you are using has an output head,
connect the head directly to the channel input.
Make sure that the AC generator output is set for a 50-ohm load for all
AC-source steps.
5- 4
TDS3000B Series Service Manual
Adjustment Procedures
Applying Fast Rise Step
Signals to all Channels
During the procedure a fast rise step signal needs to be applied simultaneously to
all channels. A typical on-screen instruction might read:
Apply -2.2 V to 0 V (unloaded), fast-rise signal (≤1 ns)
to all channels.
Use the Applying DC Voltage to Input Channels equipment setup shown on
page 5--3.
NOTE. Make sure to set the generator source impedance to 50 ohms.
Set the fast-rise signal repetition rate to anywhere between 100 Hz and 1 MHz,
inclusive.
The fast-rise signal Pk-Pk range is -2.2 V to 0 V (unloaded). Measure the
fast-rise signal, using an independent device with an input termination set to
1 MΩ or greater, to verify that the fast-rise signal does vary between --2.2 V and
0 V, regardless of the generator’s programmed value. This ensures that there is
enough signal range to adjust either 2-channel or 4-channel oscilloscopes.
Make sure that the coax cable connection path length is the same for all
channels.
Applying DC Voltage to
the External Trigger
If you are adjusting a two-channel oscilloscope, a DC voltage needs to be
applied to the external trigger input. A typical on-screen instruction might read:
Apply -5.00 V DC signal to external trigger input.
When you see an instruction similar to this, connect the oscilloscope to the DC
voltage source and set the DC voltage to the specified value.

Adjustment Procedures
Factory Adjustment Procedure
To perform the factory adjustment procedure, do these steps:
1. Connect the oscilloscope to an AC power source.
NOTE. You must connect the oscilloscope and the test equipment to the same AC
power circuit. Connect the oscilloscope and test instruments into a common
power strip if you are unsure of the AC power circuit distribution. Connecting
the oscilloscope and test instruments into separate AC power circuits can result
in offset voltages between the equipment, which can invalidate the adjustment
procedure.
2. Locate the hole that provides access to the CAL switch on the rear panel.
CAL
3. Put the adjustment tool into the CAL switch hole. Push and hold the CAL
switch in while you power on the oscilloscope. Release the switch when the
oscilloscope shows the power-on message with the oscilloscope graticule in
the background.
4. Push the SAVE/RECALL button.
5. Push the Recall Factory Setup screen button.
6. Push the OK Confirm Factory Init screen button to restore factory settings
prior to doing the factory calibration.
NOTE. Do not skip the Recall Factory Setup steps. You must recall the factory
settings in order to correctly start the factory adjustment procedure.
7. Push the MENU OFF button.

Adjustment Procedures
8. Push the UTILITY button.
9. Push the System screen button to select Cal.
10. Push the Factory screen button.
11. Push the OK Do Factory Calibration screen button to start the adjustment
process.
12. Connect signals from the DC voltage source, leveled sine wave, or fast-rise
generator as instructed by the oscilloscope display. After you connect the
correct signal, push the OK Do Next Step screen button to continue the
process.
NOTE. The oscilloscope adjusts itself automatically using the reference signal
from the DC voltage source, leveled sine wave, or fast-rise generator. There are
no manual oscilloscope adjustments that you need to make.
If you make an error, such as connecting the wrong input signal, you can repeat
the last step by pushing the Return to Previous Screen screen button.
13. Continue the adjustment process until it is complete. You can abort the
process at any time by pushing the MENU OFF button or by changing to a
different menu.
14. Do the performance verification tests (Section 4) to verify that the adjustment procedure has correctly calibrated the oscilloscope. Incorrect use of
calibration equipment can cause the oscilloscope to pass the adjustment
procedure but fail performance verification. Refer to the note on page 5--4
regarding possible injected noise for 0.000V DC input levels.

Maintenance
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules. Do service of static-sensitive
modules only at a static-free work station.
4. Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the modules over any surface.
7. Avoid handling modules in areas that have a floor or work-surface covering
capable of generating a static charge.
Inspection and Cleaning
This section describes how to inspect for dirt and damage, and how to clean the
oscilloscope. Inspection and cleaning are done as preventive maintenance.
Preventive maintenance, when done regularly, may prevent malfunctions and
enhance reliability.
Preventive maintenance consists of visually inspecting and cleaning the
oscilloscope, and using general care when operating it. How often to do
maintenance depends on the severity of the environment in which the oscilloscope is used. A proper time to perform preventive maintenance is just before
adjustment of the oscilloscope.
General Care
Protect the oscilloscope from adverse weather conditions. The oscilloscope is not
waterproof.
Do not store or leave the oscilloscope where the LCD display will be exposed to
direct sunlight for long periods of time.
CAUTION. To avoid damage to the oscilloscope, do not expose it to any sprays,
liquids, or solvents.
Inspection and Cleaning
Procedures
6- 2
Inspect and clean the oscilloscope as often as operating conditions require. The
collection of dirt on internal components can cause them to overheat and
breakdown. Dirt acts as an insulating blanket, preventing efficient heat dissipation. Dirt also provides an electrical conduction path that could cause an
oscilloscope failure, especially under high-humidity conditions.
TDS3000B Series Service Manual
Maintenance
Inspection — Exterior. Inspect the outside of the oscilloscope for damage, wear,
and missing parts. An oscilloscope that appears to have been dropped or
