With its variety of operating and trigger modes, the HM604 is a new in-
novative general purpose oscilloscope satisfying a wide range of exacting re-
quirements in laboratory, production, and service. The dual-channel measure-
ment amplifier ensures highly faithful waveform transfer characteristics,
which can be readily checked on the built-in fast-risetime 1 MHz Calibrator
from probe tip to CRT screen! Using Y-axis magnification, the instrument’s
high sensitivity enables stable displays of very small signals as low as 0.5
An analog output is provided for connecting multimeters or counters. Another
important feature is the internal delay line for observations of the leading edge
of a signal. As in dual-time base oscilloscopes, the HM604 features a calibra-
ted sweep delay mode, allowing smallest waveform sections to be expanded
up to 1000 times.
The
most outstanding feature, however, is the unique, newly
developed automatic After-Delay Trigger mode to ensure extremely stable
displays and jitter-free measurements of asynchronous signal sections and
bursts or pulse trains, independent of amplitude fluctuations. An active
Sync-Separator further enhances trigger quality of video frame and line sig-
nals. In the alternate trigger mode, two signals of different frequencies can be
compared.
With this state-of-the-art oscilloscope,
again sets a new price/
performance standard which is not likely to be met by others in this category.
Users will be particularly impressed by the instrument’s outstanding versatility
and ease of operation. These features are possible in the HM604 due to
meticulous attention to detail and many decades of successful
design experience.
