Hitachi V-151F - 1. Introduction; Outline of Oscilloscope; Technical Specifications

1. Introduction
1.1 Outline
Model V-151F is a single trace oscilloscope with a
bandwith of DC-15MHz and sensitivity of ImV/DIV
(Pulled x5 Gain). The time base provides a maximum
sweep speed time of 0.2uS/DIV. When magnified by
10, the sweep speed is lOOnS/DIV. High accelerated
voltage CRT, with 8 x iqdiv effective display area
and post acceleration, enables high speed pulses to
be clearly displayed.
Engineered for service in the field of television,
VTR, and computer, the V-151F is portable, easy and
features convenient operation for use in education
and industry.
o Wide bandwidth and high sensitivity
In addition to wide bandwidth, DC-15MHz, (-3dB)
this instrument provides high sensitivity of 5mV/
DIV. A 15 MHz frequency is obtained with im
proved triggered synchronization.
o Bright CRT
By using a new, highbrightness CRT, a stable ac
celerated CRT high voltage, calibration voltage
accuracy, and time base are obtained.
o TV Synchronization
A circuit for extracting the synchronizing signal
is equipped to trigger easily with a composite
video signal. TV vertical or horizontal sync
signal is automatically selected by the time base
switch.
o Improvement in portability and operation
Equipped with a convenient carrying handle and
designed for light weight, this unit is excellent
both in portability and operation with various
functions installed on the front panel.
o X-Y functions
Set the switch to X-Y.position and X-Y oscillo
scope is displayed with EXT TRIG OR [x] IN as X
axis and INPUT as Y axis.
