The HM1005 is a multi-function oscilloscope loaded with features such as
true 3-channel operation, a genuine second time base, and even a separate
second trigger facility.
Up to 6 traces can be displayed for evaluating waveform relationships by
using the alternating time base mode and all three input channels. In this
configuration, the normal signal is displayed together with the expanded
signal section. The second trigger facility, with its own separate slope
and level control, provides for the stable viewing of normally troublesome
asynchronous signal components.
The main time base trigger circuit is designed to provide reliable
triggering to greater than 130 MHz, at signal levels as low as 1 division.
A user-selectable x10 magnifier extends the maximum sweep range to
5ns/division.
An active TV Sync Separator extracts clean field and line sync. pulses to
ensure a high degree of display stability when viewing composite video
signals. The built-in delay line permits viewing of the trigger edge at
all times. The overscan feature indicates if any part of the trace passes
beyond the vertical limits of the CRT screen.
An analog Y-output, switchable to Channel I or II, allows further external
processing of the signal. Another new feature on the HM 1005 is the easy to
read 3-digit LED delay time multiplier for accurate measurements.
The HM 1005 offers the right combination of triggering control, frequency
response and time base versatility, to facilitate measurements in every
enviroment from Workshop to Field service.
