The complete family consists of 4 Analog- and 4 Analog-/Digital Oscilloscopes. The latter are so called CombiScopes with Bandwidths between 50 and 200 MHz, Real Time Sampling Rates from 500 MSa/s to 2 GSa/s and up to 2 Mb Memory. Common features are: the user interface that enables intuitive operation, a multilingual menu, direct operation of most important functions, help functions, wide mathematic and cursor measurement functions; as well as interface options like USB, IEEE-488 and Ethernet. Probes are recognised automatically. Further features are a 6 Digit Frequency Counter and extensive possibilities in video triggering. In addition, 2 models feature 2 Logic Inputs and logic triggering. A common feature of all models is that they do not cause noise pollution as no fan is required.

Universities, schools and training facilities are the traditional clientele. HAMEG therefore attaches great importance to quality, ease of operation and especially measurement result reliability. For this reason HAMEG offers both Analog and Analog/Digital Oscilloscopes (CombiScopes). For elementary physical reasons, analog oscilloscopes offer an unmatched signal display quality and the highest refresh rate. Digital Storage Oscilloscopes however do not show the signal direct, but as a more or less correct reconstruction of separate samples which could be distorted beyond recognition (aliasing). Thus displayed values can be wrong by large factors. One of many reasons for this is the fact that DSOs have to reduce the sampling rate if slower time base settings are chosen. This can cause only kSa/s to be effected instead of GSa/s, without knowledge of the operator. Such problems can be largely avoided by the use of high memory depth. By this reason HAMEG uses memories with 2MSamples capacity in the top models, so that even at 200 µs/cm, the highest sampling rate is present while competitors with 10 kSamples memory are forced to reduce the sampling rate to 10 MSamples at 200 µs/cm range.

Although DSOs in principle can not replace analog oscilloscopes, they offer advantages when single events have to be captured or slow signals must be recorded. CombiScopes offer the best of both worlds: one keystroke switches from analog to digital mode, so that an erroneous signal display attracts the user's attention. Pure DSOs do not offer this, and often cause measurement errors in practice. The operator can only be sure that measuring results are correct if he uses an Analog or CombiScope.
