The HAMEG HM604, manufactured in 1988, is a 60 MHz dual‑channel analogue bench oscilloscope in very good condition, tested and working, weighing about 8 kg, with an original manual and power cord.
Description from the seller
The Hameg HM‑604 Oscilloscope is a dual-channel analog bench oscilloscope produced in the late 1980s by the German company HAMEG GmbH. It was designed as a general-purpose laboratory and service instrument for electronics troubleshooting, education, and research.
Description
The Hameg HM-604 is a 60 MHz analog oscilloscope with two input channels that allows simultaneous viewing and comparison of two electrical signals. It uses a CRT display and offers advanced triggering modes, a built-in calibration generator, and a delay line for observing the leading edge of signals.
The instrument was widely used in electronics laboratories, service centers, and technical schools because of its reliable analog measurement performance and relatively compact design.
One of its notable features is the automatic After-Delay Trigger mode, which stabilizes waveform displays even for asynchronous signals or pulse trains.
