Change inform ation, if any, affecting this section w ill be found at the rear o f the manual.
Introduction
The T ektronix 434 Oscilloscope is a solid-state portable
instrument that combines small size and light weight with
the ability to make precision waveform measurements. It is
designed for general-purpose applications where display
storage is desired, along w ith conventional (non-store)
operation. The instrument is mechanically designed to w ith
stand the shock, vibration, and other extremes of environ
ment associated w ith portability.
The dual-channel DC-to-25 megahertz vertical system
provides calibrated deflection factors from 1 m illivolt to 10
volts/division. The trigger circuits provide stable triggering
over the full range of vertical frequency response. The hori
zontal deflection system provides calibrated unmagnified
sweep rates from 5 seconds to 0.2 microsecond/division. A
push-to-turn direct-reading six-position magnifier allows
sweep magnification up to a maximum of 50 times and
provides a maximum sweep rate of 0.02 microsecond/
division.
X-Y measurements can be made applying the vertical (Y)
signal to one of the vertical input connectors (appropriate
vertical mode of operation selected) and the horizontal (X)
signal to the EXT HORIZ connector on the instrum ent rear
panel (T IM E /D IV switch set to EXT HORIZ).
The cathode-ray tube is a direct view, bistable storage
tube having an 8 X 10 division display area divided into two
4X10 division storage screens. The storage screens are
independently controlled fo r split-screen applications. A
non-storing area to the left of the storage screens permits
beam location w itho ut disturbing a stored display.
The regulated low-voltage power supply assures that
instrument performance is not affected by variations in line
voltage and frequency. A new design light-weight, high
efficiency power supply used in the 434 permits instrument
operation over a wide range of line voltages and frequencies
w ithou t line voltage range selection.
Inform ation given in this instruction manual applies to
the R434 also unless otherwise indicated. The R434 is
electrically identical to the 434, but is adapted fo r mounting
in a standard 19-inch rack. Rackmounting instructions and
a dimensional drawing for the R434 are provided in Section
6 of this manual.
The electrical characteristics which follow are divided
into two categories. Characteristics listed in the Performance
Requirement column are instrument specifications, and are
checked in the Performance Check procedure provided in
the Calibration section. Data in the Supplemental Informa
tion column does not constitute instrum ent specifications
and is provided fo r reference only. The follow ing electrical
characteristics apply over an ambient temperature range of
— 15°C to +55°C, except as otherwise indicated. Warm-up
time for given accuracy is 30 minutes.
