Introduction

The Sony/Tektronix Type 324 Oscilloscope is a solid-
state portable instrument that combines small size and light
weight with the ability to make precision waveform meas­
urements. The instrument is mechanically constructed to
withstand the shock, vibration and other extremes of
environment associated with portability. A DC to 10 mega­
hertz vertical system provides calibrated deflection factors
from 0.01 volt to 20 volts/division (0.002 volt/division min­
imum with reduced frequency response). The trigger cir­
cuits provide stable triggering over the full vertical band­
width. The horizontal deflection system provides calibrated
sweep rates from 0.2 second to 1 microsecond/division. A
X5 horizontal magnifier allows each sweep rate to be in­
creased 5 times to provide a maximum sweep rate of 0.2
microsecond/division in the
ments can be made by applying the vertical (Y) signal to
the VERT INPUT connector and the horizontal (X) signal
to the EXT TRIG OR HORIZ INPUT connector (TIM E/

The Type 324 can be operated from any one of three
power sources; AC line, external DC, or internal recharge­
able batteries. A power regulator circuit assures that instru­
ment performance is unaffected by variations in internal
battery charge level, applied DC voltage, or AC line voltage
and frequency. Operation from an AC line also provides full
or trickle charging for the internal batteries.
The electrical characteristics which follow are divided
into two categories. The instrument is checked in the Per­
formance Check/Calibration Section against the character­
istics listed under Performance Requirement. The following
electrical characteristics apply over a calibration interval of
500 hours at an ambient temperature range of —15°C to
+55°C, except as otherwise indicated. Warmup time for
given accuracy is 10 seconds.
