TiePie engineering has unveiled a PC oscilloscope that can sample at 1 Giga samples per second on one channel, 500 Mega samples per second 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. Therefore the TiePieSCOPE is equiped with a large memory buffer of 32 Mega samples per channel. This enables long measurements at full speed.

The TiePieSCOPE HS805 is equiped with an on-board Arbitrary Waveform Generator. This waveform generator allows to generate signals up to 20 MHz, with amplitudes up to 12 Volt 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 32 Mega samples is available. The maximum sampling clock for generating signals is 200 MS/s. The generator can also be used to generate previously measured signals.

Typical applications for the TiePieSCOPE HS805 with it's 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. 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 H805 comes with sophisticated Multi Channel measurement software that turns your TiePieSCOPE HS805 into an oscilloscope, a multi-meter, a spectrum analyser and a transient recorder.

Mathematical operations
Mathematical operations like adding, subtracting, multiplying, dividing, integrating, differentiating etc. 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 unrivalled 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 disc in various common formats. The software also provides an I2C protocol analyser and a serial protocol analyser.
