Class:
Type:
SubType:
100 MHz general-purpose oscilloscope

Information

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.
