Innovation right from the Beginning…

Without doubt the oscilloscope is the primary measuring instrument when it comes to characterisation of signal curve shapes in the time domain. In recent years the demand for pure analogue instruments has decreased, because DSOs (digital storage oscilloscope) provide users, at higher cost, with numerous advantageous features like documentability of measurements, smaller size instruments or a Mixed Signal Oscilloscope (MSO) function (simultaneous display of the acquired analogue and digital data).

Facing a broad mix of applications and budgets in industry, service, handcraft, science, training and private use, HAMEG Instruments offers a diversified portfolio of conventional CRTs (Cathode Ray Tube) in pure analogue or mixed design (CombiScope^®) as well as modern DSO/MSO instruments.

A host of applications in industry and handcraft are well served with a standard analogue scope or a CombiScope^®, to adequately perform troubleshooting on electronic assemblies and appliances. Modern devices are more and more often equipped with microcontrollers, FPGA´s and high speed interfaces. Their internal processing often uses square wave signals with frequency ranges more than 20MHz. Of course a 50MHz scope can only display the base wave and first, possibly second harmonic overtone. This can lead to considerably erroneous indications of the signal. Regarding analogue scopes, this could be tolerated, as it “only” results in amplitude errors in the cut-off frequency area. But considering DSOs/MSOs, the Nyquist sampling theorem occurs. Then, for recording a 20MHz square wave signal, an instrument with a sampling rate of at least 100MS/s, even better 200MS/s, should be used.

Bandwidth and sampling rate are the most focused criteria when searching for a new DSO to purchase. Unfortunately, the advertised sampling rate often can’t be used, when the critical signal curves are very far away from the trigger point to be recorded in a restricted memory depth of only a few thousand sampling points. HAMEG is clearly aware of this and offers the three vital criteria topics in a truly balanced composition to ensure meaningful results.

Last but not least our 50 years of experience in oscilloscope technology stand for excellent trigger performance, outstanding input sensitivity, low-noise A/D conversion, unequalled long live cycle and an excellent price-performance ratio.
