SPECIFICATION
INTRODUCTION
ACCESSORIES
The TEKTRONIX 2205 Oscilloscope is a rugged,
lightweight, dual-channel, 20 MHz instrument that
features a bright, sharply defined trace on an 80 by
100 mm cathode-ray tube (crt).
Its low-noise vertical system supplies calibrated
deflection factors from 5 mV to 5 V per division at
full bandwidth.
Stable triggering Is achieved over the full
bandwidth of the vertical system. The flexibility and
high sensitivity of the trigger system provides a
range of conveniences such as hands-free trigî™–
gering with the peak-to-peak automatic mode, indeî™–
pendent selection of TV line and TV field triggering at
any sweep speed, and single-sweep triggering. The
trigger signal is do coupled. An external triggering
signal or an external 2-axis modulation signal can be
applied via a front-panel connector and the source-
seiector switches.
The horizontal system provides calibrated sweep
speeds from 0.5 s to 100 ns per division. For greater
measurement accuracy, a X I0 magnifier circuit exî™–
tends the maximum sweep speed to 10 ns per
division.
The instrument is shipped with the following
accessories:
1 Operators Manual
2 IX Signal Adapters
1 Power Cord
2 Fuses
1 Power Cord Clamp
1 Washer
1 Screw
Part numbers for these standard accessories, as
well as for other optional accessories, are located in
Section 7, Options and Accessories. The voltageî™–
sensing signal adapters were designed specifically
to complement the performance of your 2205.
