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
deflectionfactors 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
50R 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 15pF, with DC input-
signalcoupling.Trigger circuitsenable stable triggeringover
the full bandwidthof the vertical system.
The horizontal deflection system provides calibrated
sweepspeeds from 1.5 s per divisionto 500 ps per division.
Drivefor the horizontaldeflection system is obtained from a
choiceof A,
B
delayed, A alternatedwith Bdelayed sweeps,
or CH 1 (for the X-Y display mode).
The 2465 incorporates alphanumeric crt readoutsof the
verticaland horizontalscale factors, the trigger levels, time-
difference measurement values, voltage-difference
measurement values, and certain auxiliary information.
