Informationen
The BWD 821 Oscilloscope is a remarkable instrument. It
offers a 50MHz bandwidth at 5mV/div, 75MHz triggering, and
incorporates a completely new MIX--MAG facility. This unique
BWD feature enables both the normal x1 display and a x10
magnified display to be presented simultaneously at the turn
of a knob. The magnified portion of the trace can extend
from 0 to over 80% of the trace length.
If the normal xlO magnifier is used with the MIX-MAG, the
trace can be magnified x100 to a maximum sweep speed of
approx 10nsec/div.
These features, together with a 1mV/div max sensitivity, a
wide range time base from 0.02jjs/div down to 2.5 sec/div
and an amplifier rise time of less than 7 nano seconds is
suited to a large number of applications. It accurately
displays fast digital pulses from TTL, CMOS or even ECL
circuits making it suited for uprocessors, small home or
business computers, video games and other digital equipments.
A video sync separator with automatic change over from frame
to line lock makes servicing of video cassette recorders,
colour TV’s and all other video products a simple matter.
the 1mV/div sensitivity vertical amplifiers can be switched
to differential operation to view signals developed at any
point in the circuit from the recording to the playback heads.
The same features that are ideal for video work are also
excellent for all audio applications, including the new
digital recording techniques. An identical ECS facility with
low phase shift to 200kHz is incorporated for specialist
audio and telecommunication measurements. A useful feature
of the video sync separator is that it will also demodulate
a modulated carrier to enable the carrier envelope to be
displayed.
To ensure the high performance characteristics will be
maintained, the BWD 821 is built to high standards of
manufacture and reliability. It closely conforms to I EC 348
recommendations and other relevant standards of safety in
high quality electronic test equipment.
