Tektronix 314 Manual

OPERATING INFORMATION
INTRODUCTION
NOTE
The Sony-Tektronix 314 is a dual-channel, 10 MHz portable
storage oscilloscope.
The de to 10 MHz vertical bandwidth provides calibrated
deflection factors from 1 mV to 10 V/graticule div (25 V/div,
or greater, uncalibrated, with VOLTS/DIV VARIABLE in
fully counterclockwise position). A delay line in the verti 
cal system permits observation of that part of the signal
which triggers the sweep.
The horizontal deflection system provides calibrated sweep
rates from 5 s/div to 1 µs/div; and a 10X sweep magnifier to
increase the fastest sweep rate to 0.1 µs/div. Three sweep
modes are available: AUTO, NORM, and SINGLE SWEEP.
The trigger circuit provides a stable display over the full
vertical bandwidth.
External horizontal input provides deflection factors of
20 mV to 2 V/div for X-Y operation.
The ert is a direct-view bistable storage device having an
8 x 10 div internal graticule. Each graticule div equals 0.25
inch. An enhance mode increases single-sweep writing speed.
An internal 1 kHz calibrator is connected internally to the
vertical inputs and to a front-panel connector.
The 314 is operated from a line voltage of 100, 115, 120,
200, 230, or 240 V ac, 48 to 440 Hz, or from a +12 or
+24 V de source.
The 314 automatically reduces the display intensity
level when sweep speeds of 10 ms and slower are
selected. This reduces the possibility of accidentally
burning the sensitive storage ert phosphor at slower
sweep speeds.
When changing from sweep speed settings faster than
10 ms to settings of 10 ms and slower, readjust the
INTENSITY control setting as necessary for a visible
display.
SAFETY INFORMATION
The instrument is designed to operate from a single-phase
power source having one of the current-carrying conductors
(the neutral conductor) at ground (earth) potential. Oper 
ation from power sources where both current-carrying
conductors are live with respect to ground (such as phase-
to-phase on a three-wire system) is not recommended since
only the line conductor has overcurrent (fuse) protection
within the instrument.
The instrument has a three-wire power cord with a three-
terminal polarized plug for connection to the power source
and safety earth. The ground (earth) terminal of the plug
is directly connected to the instrument frame. For elec 
tric shock protection, insert this plug into only a mating
outlet with a safety earth contact.
