Faircild Instrumentation 765 Osciloscópio
Fabricante:
Faircild Instrumentation
Modelo: 765

Categoria: Instrumentos de medição
Grupo: Osciloscópio
Descrição:
Informações:
                                    The Fairchild Types 765, 766, and 767 Family of
Oscilloscopes are available in three basic form factors:
bench, rack, and portable models. The Portable Models are
identified by the Type 765 numerical Series; the Bench
Models by the Type 766 numerical Series, and the
Rack-mounted Models by the Type 767 numerical Series.

In addition, there are alphabetical suffixes appended to the
numerical series to identify special electronic circuits.
The suffix H denotes the high-voltage oscilloscope with an
accelerating potential of 13 Kv. The low voltage option is 5
Kv and these series oscilloscopes are identified by the
absence of the H alphabetical suffix.

The suffix H/F denotes the high-voltage, high-frequency
model. These models are provided with the Type 7062 CRT
Termination Network to enable them to accommodate the Type
79-02A DC to 100 Me Plug-in Amplifier. The suffix M denotes
the militarized model. Further details for all of the models
are listed in the Specifications.

Since the electrical circuits are identical in all models
except for minor differences, discussion will be confined to
the Type 766H Series Oscilloscope. All references to the
Type 766H Series will be equally applicable to the other
models unless otherwise indicated.

To simplify discussion, the Type 766H Series Oscilloscope
may be categorized into three basic Series: (1) Low-voltage,
(2) High-voltage, and (3) High Frequency.

1.	The following models comprise the low-voltage Series:

Type 765, 765M, 766, 766M, 767, and 767M

2.	The following models comprise the high-voltage

Series:

Type 765H, 765MH, 766H, 766MH, 767H,

767MH

3.	The following models comprise the high-frequency Series:*

Type 765H/F, 765MH/F, 766H/F, 766MH/F,

767H/F, & 767MH/F
*Note: These oscilloscopes are electrically identical to the
high-voltage series except for the addition of the
high-frequency CRT Termination Network.

Separate manuals are provided for each of the plugin units.
If desired, these manuals may be inserted into the same
binder supplied with your Indicator unit.

1-2. FEATURES

The Fairchild Type 766H Family of Oscilloscopes consists of
an Indicator Unit and any two of a number of available
plug-in modules. The Indicator Unit contains the power
supplies, a cathode-ray tube with associated circuitry, and
an internal amplitude calibrator.

The plug-in modules take the place of the vertical and
horizontal deflection systems of a conventional
oscilloscope, and their outputs are connected directly to
the deflection plates of the cathode-ray tube.

All plug-ins in the Type 74-00 and 76-00 Series may be used
universally in the oscilloscope. The plug-in modules may be
selected to give a degree and type of performance demanded
of them by the particular application for which they are to
be used.

•	13 Kv accelerating potential (low-voltage option:

5 Kv)	" '	'	’ '

•	Quality display area of 6 cm by 10 cm

•	Three basic Main Frames available: Portable (Type 765-),
Bench (Type 766-) and Rackmounted (Type 767-)

•	Silicon solid state circuitry

•	Dual Plug-in capability (DC to 100 Me) with all High
Frequency or H/F Models

•	Z-axis input provided on all bench and rackmounted models

•	Illuminated internal graticule optionally available

•	Silicon transistors and fully regulated electronic power
supplies, assure maximum drift stability and long-term
reliability
