SPECIFICATION
INTRODUCTION
The TEKTRONIX 2465 Oscilloscope is a portable 300-
MHz instrument having a four-channel vertical deflection
system. Channel 1 and Channel 2 provide calibrated
deflection factors from 2 mV per division to 5 V per division.
For each of these channels, input impedance is selectable
between two values: either 1
MR in parallel with 15 pF, or
50 R internal termination. Input-signal coupling with 1-MR
impedance can be selected as either AC or DC. Channel 3
and Channel 4 have deflection factors of either 0.1 V or
0.5 V per division. Each of these channels has an input
impedance of 1 MR in parallel with 15 pF, with DC input-
signal coupling. Trigger circuits enable stable triggering over
the full bandwidth of the vertical system.
The horizontal deflection system provides calibrated
sweep speeds from 1.5 s per division to 500 ps per division.
Drive for the horizontal deflection system is obtained from a
choice of A,
B
delayed, A alternated with B delayed sweeps,
or CH 1 (for the X-Y display mode).
The 2465 incorporates alphanumeric crt readouts of the
vertical and horizontal scale factors, the trigger levels,
time-
difference measurement values, voltage-difference
measurement values, and certain auxiliary information.
The 2465 Oscilloscope is shipped with the following
standard accessories:
Probe packages
Snap-lock accessories pouch
Zip-lock accessories pouch
Operators manual
Power cord (installed)
2-A, 250-V fuse
Clear plastic crt filter

For part numbers and further information about both
standard and optional accessories, refer to the "Options
and Accessoriesn section (Section
7)
of this manual. Your
Tektronix representative, local Tektronix Field Office, or
Tektronix product catalog can also provide accessories
information.
PERFORMANCE CONDITIONS
The following electrical characteristics (Table 1-1) are
valid for the 2465 when it has been adjusted at an ambient
temperature between
+
20°C and +30°C, has had a warm-
up period of at least 20 minutes, and is operating at an
ambient temperature between
-
1 5
O
C and
+
55
O
C (unless
otherwise noted).
Items listed in the "Performance Requirements" column
are verifiable qualitative or quantitative limits that define the
measurement capabilities of the instrument.
Environmental characteristics are given in Table 1-2. The
2465 Oscilloscope meets the environmental requirements of
MIL-T-28800C for Type
Ill,
Class
3,
Style C equipment, with
the humidity and temperature requirements defined in
paragraphs 3.9.2.2, 3.9.2.3, and
3.9.2.4.
Mechanical characteristics of the 2465 are listed in
Table 1-3.
