Informazioni
PM 3267 has been designed for a wide range of applications -
from the simple to the sophisticated - in workshops,
laboratories or tough field conditions. In particular those
engineers with nonspecialist experience in electronics
seeking easy-to-operate test equipment will find the PM 3267
a most useful, uncomplicated tool, well within the scope of
their understanding.
Its vertical deflection characteristics make it more than
adequate to use with modern logic techniques, whilst its
wide trigger bandwidth allows the display of very high
frequency, complex signals.
Its many attractive features include: -Trigger view which
allows the active trigger point to be observed on a third
channel
-Alternate time base switching for
simultaneous display of a complete signal and magnified
detail over the full screen width
- Independent triggering of the main and delayed time bases,
very important in digital applications
-Automatic triggering including video waveform applications
- External Z-modulation facility allowing an additional
timing facility via blanked markers
- 'Out of calibration' warnings indicated by front panel lamps
The instrument will operate from an external 24Vqc power
supply as well as standard line voltages between 90V and
270V (up to 440 Hz). This facility, plus the completely
sealed sturdy metal case, increase the application
possibilities beyond the laboratory or workbench, into more
hostile environments.
Flexible triggering
Main and delayed time bases can be triggered independently
and composite triggering is possible. TV triggering vyith
automatic changeover from line to 18
frame is standard. Capturing single shot signals is
simplified by a LED indicator which illuminates when the
instrument has triggered.
Automatic triggering of ECL or TTL levels is an optional extra.
