TiePie engineering has released the TiePieSCOPE HS805, a PC oscilloscope that can sample at 1GSps on one channel, 500MSps simultaneously on two channels, real time. To display the measured signals accurately and without distortion, the TiePieSCOPE HS805 has a high bandwidth of 250 MHz.

When measuring at high sample rates, a long record length is a must, otherwise the acquisition buffer is full before the signal is measured. The TiePieSCOPE is equipped with a large memory buffer of 32MSps per channel, enabling long measurements at full speed.

The TiePieSCOPE HS805 is also equipped with an on-board Arbitrary Waveform Generator that allows to generate signals up to 20MHz, with amplitudes up to 12V peak value. Signal shapes include sine wave, square wave, triangular wave, noise and user-defined arbitrary signal shapes. For arbitrary signals, a waveform buffer of 32MSps is available. The maximum sampling clock for generating signals is 200MSps. The generator can also be used to generate previously measured signals.

Typical applications for the TiePieSCOPE HS805 with high sampling rate and long record length are debugging fast serial communications, like SPI, ProfiBus and CAN bus signals. The high sampling rate enables capturing the fine details of the signal while the long record length makes sure that a complete block of the serial communication can be captured. The AWG can then be used to regenerate the signal, to simulate the original source in your lab.

The TiePieSCOPE HS805 also comes with sophisticated multichannel measurement software that turns the it into an oscilloscope, a multimeter, a spectrum analyzer and a transient recorder.

In addition, mathematical operations like adding, subtracting, multiplying, dividing, integrating, differentiating are available in the form of processing blocks. Besides the mathematical operations, there are also several processing blocks to perform other operations on the data, like determining minimum or maximum values, limiting to specified range, averaging, filtering, applying gain and offset, etc. Combining these mathematical processing blocks gives unrivaled possibilities in constructing complex mathematical operations. The results of these operations can be displayed in one or more graphs, can be displayed in numeric displays and can be written to disk in various common formats. The software also provides an I?C protocol analyzer and a serial protocol analyzer.
