The unique construction of the M774 oscilloscope provides a pair of isolated inputs. Isolation introduces increased security when measuring the voltage beyond safe levels, and makes measurement much more resistant to noise caused by grounding to multiple points.
This means the device is perfect for measurement on complex systems where the probability of multiple grounding is quite high (such as communication hubs). The M774 is ideal for measurements on power systems, because the isolation together with possibility of safety grounding greatly decreases risk of electric shock.
The 1MS memory per channel enables you to perform detailed analysis of fast, long processes (such as digital communication).
The device has a metal casing which can withstand rough manipulation and is fully recyclable.
The M774 offers precise electronic engineering and automated calibration processes during manufacturing. Each kit contains a traceable calibration certificate. The inputs withstand ±200V, which is quite rare in this category.
The used memory size is configurable. This allows you to switch between high update rates (short memory) and high data amounts (large memory) easily. Since the M774 device uses USB 2.0 for communication (with automatic fallback to USB 1.1), it provides you with high refresh rates comparable to stand-alone devices.
Software The basic package contains complex yet easy-to-use oscilloscope software (Scope). Scope allows you to control the oscilloscope, use advanced functions (such as FFT, persistent display mode, mask testing) or export the data. The Spectrum Analyzer software is the part of the basic package as well.
Each kit includes a license for Roll Mode software, which allows you to acquire data as fast as 2.5MS/s and store them directly to the hard drive. You can use either the viewer to analyze the data, or export tools to analyze data in third-party applications.
Support ETC provides unlimited tech support, and software updates also are free of charge always.
