High-speed sampling and expanded memory are essential for simultaneously observing switching carrier waveforms and basic waveforms. Furthermore, greater memory has been requested by users to allow measurement of sporadic and unpredictable events and signals that cannot be triggered. The 20 MS/s highspeed sampling and a memory capacity of up to 512 megawords (1 GB, optional) of the 8855 MEMORY HiCORDER makes it the best-equipped isolated digital oscilloscope on the market, and the ideal instrument to search for and analyze anomalous waveforms.

The 8855 can be used to observe various inverter waveforms. To provide stable measurement of voltage waveforms, the 8855 uses high-frequency, noise-resistant CMRR and maintains high floating voltages with isolated inputs. When observing current waveforms, you can install a special amplifier unit for current measurement that allows you to use a supersensitive, broadband clamp-on probe to perform measurements without breaking the electric circuit.

When performing engine characterization analysis, the 8855 is ideally-suited to measuring waveforms derived from boost pressure, oil pressure, air-fuel ratio, ignition timing, rotation speed, or injector opening. The 8855 also has an expanded memory for storing large quantities of data taken in various conditions. The 8855 can be used to observe pressure waveforms, such as those for fuel injection lines or jet pumps, and then compare them with standard waveforms.
