Opis:
5 inch Dual Beam Oscilloscope
Informacja
Model bwd 521/521R is a true double beam, precision
Oscilloscope possessing by virtue of its
range of Plug-In Amplifiers and Time Bases a wide measuring
range of both voltage and time.
1 .1 The instrument is 100% Silicon Solid State design
employing no valves or neons other than the double gun CRT
and panel indicators. It incorporates three identical
Plug-In compartments for the series '5' interchangeable
plug-ins providing facilities for single trace, dual trace,
with similar or dissimilar amplifiers , delayed sweep,
identical X-Y operation or raster type displays. As no
partition exists between the Plug-In compartments special
twin or triple units can be supplied for specific applications.
1 .2 The main frame consists ot the 5" double gun CRT, all
low voltage power supplies, EHT supplies, two <.30MHz
vertical amplifiers,< 1.5MHz horizontal Amplifier,
Calibrator and Plug-In cage, etc . All DC supplies are
electronically regulated to accommodate input voltage and
lead variations.
1 .3 An additional feature of this model is in the complete
DC isolation of all circuits permitting the input COMMON
terminal to be connected to DC voltage rails up to ± 400V
from ground, making isolated measurements as simple as
clipping a meter across the circuit.
1 .4 Where signals require measuring between two points,
both of which are varying with respect to a reference or
ground rail, Differential Amplifiers Models 5A or 5C can be
employed in which either input can be separately AC or DC
coupled to further increase their measuring flexibility.
1 .5 All inputs are protected against overload. However,
care must always be exercised to not exceed the specified
voltage limits of each input and, in particular, do not
attempt to connect the COMMON of each Plug-In to different
voltages or damage may result to the power supplies or
printed circuit ground line tracks.
1 .6 It has been designed for reliable long-term use and has
been subjected to environmental tests. Each instrument is
heat soaked and vibrated as part of its alignment procedure.
1 .7 For maximum reliability it is advisable to replace the
Power supply protection fuses every 2000 hours of operation
to guard against thermal stress failure. Additionally, if
the instrument is to be left non-operating for long periods
and is stored in a dusty atmosphere, it is wise to drop a
plastic protection cover over it to minimise dust ingress
into switch wafers, etc . A storage cover and a carrying
case are available from B.W.D. Electronics piy. Ltd.,
together with a full range of Accessories (see catalogue).
