General Information
Introduction
The TEKTRONIX 2467 portable oscilloscope has four vertical channels with
350 MHz bandwidth. Through channels 1 and 2, deflection factors from 2 mV to 5 V
per division can be selected, in a 1-2-5 sequence, with either 1 M!l or 50 n input
resistance. With 1 Mn input resistance, compatible with the standard accessory
probes, either AC or DC input-signal coupling is available. Channels 3 and 4 give
either 0.1 V or 0.5 V per division, with 1 M!l input resistance, and DC input-signal
coupling.
The trigger system works automatically for most signals. It operates with versatile
mode selection, any of the four channels as a source, and optimum couplings for a
wide range of signals. The trigger gives stable displays from de to 500 MHz.
All sweep speeds are continuously calibrated, from 1.5 s to 500 ps per division,
including the X10 magnifier and the variable range between 1-2-5 steps. Horizontal
display choices include A-Sweep, B-Sweep (delayed), A alternated with B, and CH 1
(for X/Y displays).
The 2467 yields 4 divisions/ns visual writing rate. This is about 100 times faster
than conventional, high-performance oscilloscopes. The 2467 visibly displays any
signal, at any repetition-rate, at any sweep speed, in typical room light. Visible single-
shots include 1 ns steps at 500 ps/division.
The AUTO, SAVE, and RECALL features save time and prevent errors, whether
you are a novice operator or a master. Pressing the AUTO Setup button gives a
workable setup for almost any signal. For repetitive measurements, the Save and
Recall functions record and immediately or sequentially restore as many as 20
instrument setups. The SETUP buttons operate all instrument functions, including the
extended function options.
Direct, on-screen readouts of time measurements, voltage measurements, scale
factors, trigger levels, and auxiliary information also save time and improve operator
confidence.

General Information
Preparation for Use
Safety
Before connecting the oscilloscope to a power source, read entirely both this
section and the Safety Summary at the front of this manual. Be sure you have the
training required to safely connect the instrument inputs to the signals you will be
measuring. Refer to the Safety Summary for power source, grounding, and other
safety considerations pertaining to the use of the instrument.
This instrument may be damaged if operated with the LINE VOLTAGE
SELECTOR switch set for the wrong applied ac input-source voltage or if
the wrong line fuse is installed.
Line Voltage Selection
The oscilloscope operates from either a 115-V or a 230-V nominal ac power-line
with any frequency from 48 Hz to 440 Hz. Before connecting the power cord to a
power source, verify that the LINE VOLTAGE SELECTOR switch, located on the
rear panel (see Figure 1-1 ), is set correctly (see Table 1-1) and that the line fuse is
correct. To convert the instrument for operation on the other line-voltage range,
move the LINE VOLTAGE SELECTOR switch to the correct nominal ac source-
voltage setting. The detachable power cord may have to be replaced to match the
particular power source.
Line Fuse
1-2
To verify the instrument power-input fuse rating, do the following steps:
1. Press the fuse-holder cap and release it with a slight counterclockwise
rotation. Pull the cap (with the attached fuse inside) out of the fuse holder.
2. Verify that the fuse is of the type listed on the back of the instrument.
Then install the proper fuse and reinstall the proper fuse-holder cap. The
two types of fuses listed are not directly interchangeable; they require
different types of fuse caps. Included in the accessory pouch is a 5x20 mm
fuse holder cap for use with 1.6 A, 250 V, 5x20 mm (IEC 127) fuses.

General Information
Instruments are shipped with the required power cord as ordered by the
customer. Available power-cord information is presented in Table 1-1, and part
numbers are listed in "Options and Accessories· (Section 7). Contact your
Tektronix representative or local Tektronix Field Office for additional power-cord
information.
Instrument Cooling
To prevent instrument damage from internally generated heat, adequate air flow
must be maintained. Before turning on the power, verify that the spaces around the
air-intake holes on the bottom of the cabinet and the fan-exhaust holes in the rear
panel are free of any obstruction to airflow.
Start-up
The oscilloscope automatically performs a set of diagnostic tests each time the
instrument is turned on. These tests warn the user of any available indication that
the instrument may not be fully functional. The tests run for several seconds after
power is applied. If no faults are encountered, the instrument operates normally. A
failure of any of the power-up tests will be indicated by either a flashing TRIG'D
indicator on the instrument front panel or a bottom-line readout on the CRT in the
form: TEST XX FAIL VY (where XX is the test number and VY is the failure code
of the failed test).
If a failure of any power-up test occurs, the instrument may still be usable for
some applications. To operate the~nstrument after a power-up test failure, press
the A/B TRIG button. Even if the instrument then functions for your particular
measurement requirement, it should be repaired by a qualified service technician at
the earliest convenience. Additional information on the power-up tests may be
found in Appendix A at the rear of this manual. Consult your service department,
your local Tektronix Service Center, or nearest Tektronix representative if
additional assistance is needed.

Operation
Introduction
Basic measurements require only simple operations with a few controls. In
addition, the instrument can also analyze the details of complex signals or measure
the characteristics of unusual signals.
The best way to use this information is "hands-on· with the oscilloscope and a
signal source. More detailed information may be found in the ·controls,
Connectors, and Indicators" section of this manual. See Figure 2-1 for a drawing of
the instrument front panel.
Fundamentals
Like any oscilloscope, this instrument draws a graph of voltage as a function of
time. The controls in the VERTICAL section of the front panel, marked off by a
heavy gray line, define the voltage axis of the display. The SEC/DIV, horizontal
POSITION, and X10 MAG controls define the time axis of the display. The
TRIGGER controls, marked off by a green box, define a reference point on a
signal. The instrument locks the time axis (sweep) to this point. The controls under
the crt affect the visual characteristics of the display, but do not affect the
waveform.
Getting a Display
AUTO Setup initializes the vertical, horizontal, trigger, and intensity controls for
a usable display. To display a waveform:
1. Connect a probe to a signal.
2. Select the channel to which the probe is attached, using the Vertical MODE
buttons.
3. Push AUTO. (If STEP is illuminated, push RECALL first to extinguish it.)
4. If the display isn't exactly what you prefer, adjust the appropriate
VOLTS/DIV, SEC/DIV, POSITION, or Trigger controls.
You can select any combination of vertical channels and AUTO will set them up
for a useful display. If you are using the standard accessory probes, make sure the
CH 1 or CH 2 inputs are not set at 50 O.
