With the Multi Channel oscilloscope software, the world's most sophisticated measuring software, the Handyscope HS5 can be used as: High Resolution USB Oscilloscope, multimeter, spectrum analyzer, data logger/transient recorder, protocol analyzer and Arbitrary Waveform Generator. This powerful and compact measuring instrument can solve almost any measurement problem.

The Handyscope HS5 measures with high resolutions of 14 and 16 bit. A signal measured with the Handyscope HS5 therefore has 256 times more resolution than most standalone oscilloscopes, which usually have a low resolution of 8 or 9 bit. The high resolution of the Handyscope HS5 precision oscilloscope allows for measuring signals with more accuracy, because the quantization error is much lower.

The input circuit of the Handyscope HS5 has a high accuracy of 0.25 % of the full scale input range, where most standalone oscilloscopes have an accuracy of 2 - 3 % of the full scale range.

To display a signal measured with the Handyscope HS5 High Resolution oscilloscope at the same level of detail as the standalone oscilloscope, the display can be 256 times larger. Viewing the signals on a 24" monitor immediately gives a very detailed impression of the signal. The smallest deviations are very well visible and because of the high resolution, it is still possible to zoom in and reveal additional details.

Figure 1: Handyscope HS5 high visible accuracy compared to competition.

Shown in figure 1 are two displays, both showing a measurement of the same signal. The left display size corresponds to a size comparable to a standalone oscilloscope; at 8 bit resolution, zooming will not reveal more details. The right display corresponds to a maximized window on a standard PC screen; at 14 bit resolution, zooming will still reveal more details.

The high resolution and high accuracy of the Handyscope HS5 and the unlimited zoom of the Multi Channel oscilloscope software allow to zoom in to mV levels. Figure 2 shows a measurement of a 2 mV sine wave made in the 200 mV input range, which is then zoomed in to view the signal at an 8 mV scale.

Figure 2: Zoomed in to get an 8 mV input scale.

With a time base accuracy of 1 ppm, frequency and timing can be measured very accurately. The time base of the Handyscope HS5 is 25 to 100 times more accurate than comparable instruments of the competition.

Coupling multiple instruments to a large combined instrument does not affect the time base accuracy. The timing deviation between the coupled instruments is 0 ppm.

The Handyscope HS5 is the first High Resolution USB oscilloscope with built-in 30 MHz low distortion function generator. The built-in Arbitrary Waveform Generator uses CDS signal synthesis technology, developed by TiePie engineering, resulting in the best signal fidelity in its class, generating the true form of your signals. With spurious distortion as low as -85 dB at 100 kHz signal frequency, a very flat amplitude spectrum and a rise time of 8 ns, the low distortion function generator creates signals that approach perfection.

Figure 3: Handyscope HS5 function generator sine wave with extremely low spurious.

Combined with an output voltage of 24 V_pp, a resolution of 14 bit at 240 MS/s and a waveform buffer of 64 MSamples, this makes the Handyscope HS5 Arbitrary waveform generator truly a high quality low distortion function generator. Standard signal shapes like sine wave, square wave, triangle, pulse, DC and noise are available. When a custom signal shape is required, this can be created in the 64 million samples large memory or by loading a previously measured signal from the oscilloscope.

The Handyscope HS5 supports continuous streaming measurements with a speed up to 20 MS/s, which makes it possible to measure endlessly, without any memory limits. Data can be stored directly to disk using the multi channel integrated data logger, which is only limited by the amount of available disk space.

During recording, the measured signal can be viewed and analyzed in real time. The high continuous sampling frequency is high enough to log serial communication signals such as CAN bus. Using streaming measuring, difficult problems can easily be measured, traced back and analyzed.

With its high resolution of 16 bits, the Handyscope HS5 can be used as a comprehensive and accurate high performance digital multimeter, with measurements like RMS, peak-peak, Max, Min, Mean, Variance, Standard deviation, Frequency, Duty cycle, Crest factor, Rise time, Fall time, dBm, etc. Both numerical and gauge displays are available in the multimeter. The stable and 1 ppm accurate time base of the Handyscope HS5 enable very accurate frequency and time measurements. These qualities make an extra multimeter or frequency counter redundant and make the Handyscope HS5 unique in its class.

You can make as many high performance multimeter displays as you want, in any size and different layouts.

The Handyscope HS5 definitely brings an end to the idea that spectrum analyzers are expensive, hard to control and difficult to understand. The large flexibility of the spectrum analyzer makes it not just suitable for measuring high frequency signals of transmitters and receivers, but also for viewing signals that are invisible in the time domain display of an oscilloscope.

When troubleshooting, usually an oscilloscope is used, but when the amplitude of the signal of interest is small, it may be badly visible on an oscilloscope and drown in noise. When viewed with a spectrum analyzer in the frequency domain however, all spectral components of the signal and their magnitude can be clearly observed.

Figure 4: While invisible in the time domain, a small signal is clearly visible in the spectrum.

Analyzing signals in the frequency domain is very useful for example when measuring disturbances caused by a switched power supply. The switching signal of the switched mode power supply can be measured by holding the probe close to the inductor of the power supply and can be stored as a reference signal. When this reference signal is displayed besides a live spectrum during measuring, the switching signal is easily distinguished from other signals in the device under test. When taking measures to reduce the unwanted influence of the power supply, the suppression can be observed directly with the Handyscope HS5 USB spectrum analyzer.

This method of troubleshooting in the frequency domain is only possible (and unique for the Handyscope HS5) because of the Handyscope HS5's unique combination of features:

• 250 MHz bandwidth
• 14 and 16 bit resolution
• 32 Million samples memory
• very fast FFT calculations.

The high resolution of the Handyscope HS5 (14 and 16 bit) and its large large record length of 32 MSamples make it possible to perform a spectral analysis with up to 16 million frequency components with a very high resolution in the frequency domain. A spectrum with a dynamic range of more than 120 dB can be measured, which makes the Handyscope HS5 unique in its class.

When measuring at high sample rates, a long record length/large memory is necessary to be able to record a complete signal in the acquisition buffer. Where most oscilloscopes have 2.5 kSamples or 100 kSamples memory, the Handyscope HS5 has 32 MSamples memory per channel. This gives the user 300 to 10000 times more memory. An advantage of a large memory is that once-only fast phenomena can be captured completely. For example complete serial communications, like CAN bus signals, can be measured all in one record to be reviewed and analyzed afterwards.

The large memory results in the advantage of a large dynamic range in the USB spectrum analyzer, which enables troubleshooting in the frequency domain.

The unlimited superzoom feature of the Handyscope HS5 allows to zoom in to individual samples, no matter what record length is used.

Figure 5: The same signal viewed simultaneously with several zoom factors up to 30000

Figure 1 shows the same signal four times with different zooming factors. The lower right graph shows just 0.01 ms of the total 300 ms, a zoom factor of 30000 and still provides enough detail for accurate signal analysis.

The various serial protocol analyzers of the Handyscope HS5 can be used to analyze and debug serial data buses. The data is displayed in an elaborate table with information on the serial data. Locating "wrong" data packets has become very easy with a protocol analyzer. For each developer or service technician this is a welcome option. Protocol analyzers for CAN bus data, J1939, RS232, I²C communication and various other serial data communications are available with the Handyscope HS5 protocol analyzer.

The High Resolution USB oscilloscope and the arbitrary waveform generator in the Handyscope HS5 can be easily synchronized by setting the trigger source of the oscilloscope to one or more generator trigger events: start, stop and new period. This synchronization makes it possible for example to perform a sweep, and directly measure the frequency spectrum. In the shown measurement, a sweep from 1 MHz to 7 MHz is generated and injected in a resonance filter of 4 MHz of which the output is measured. As this is a real time synchronized scope with AWG measurement, a drop in resonance frequency is immediately visible when the resonance filter is heated.

The Multi Channel oscilloscope software for the Handyscope HS5 offers a large variety of mathematical operations like adding, subtracting, multiplying, dividing, integrating, differentiating, determining the square root, determining the logarithm, etc. These mathematical operations are available in the form of I/Os, also called processing blocks, and can be used to process the measured signals and reference signals.

Besides the basic mathematical operations, there are also several processing blocks to perform other, more complex mathematical operations on the data, like determining minimum or maximum values, limiting to specified range, averaging, filtering, applying gain and offset, resampling etc.

Icon	Operation	Icon	Operation
	Gain/Offset		Average
	Add/Subtract		LowPass
	Multiply/Divide		MinMax
	SQRT		Limiter
	ABS		Resampler
	Differentiate		DataCollector
	Integrate		FFT
	Log		DutyCycle

Combining these mathematical processing blocks gives unrivaled possibilities in constructing complex mathematical operations to analyze your measurements thoroughly and obtain all the information you need from your data. The results of the mathematical operations can be displayed in one or more graphs, can be displayed in numeric displays, in tables and can be written to disk in various common file formats.
