TiePie Handyscope HS4 DIFF, 4-Channel, 16Bit PC Differential Oscilloscope Series
The Handyscope HS4 DIFF is a 4-channel differential USB oscilloscope with a maximum sampling speed of 50MSa/s and 128kSa memory per channel. The digital storage oscilloscope is delivered with a complete measurement software package that offers all you need for your measurement applications.
The Handyscope HS4 DIFF oscilloscope features a user selectable 12 bit, 14 bit or 16 bit resolution, 200mV to 80V full scale input ranges each and 128kSa record length per channel.
The Handyscope HS4 DIFF is available in several variants with different maximum sampling rates on all four channels simultaneously: 5MSa/s, 10MSa/s, 25MSa/s or 50MSa/s
The variants differ in sampling rate and warranty period. (Please select when ordering!)
Differential inputs
The Handyscope HS4 DIFF features four isolated differential input channels. This makes it the ideal instrument to perform measurements in high voltage and mains circuits, amplifiers, switch mode power supplies, power inverters etc. No more risk of creating short circuits through your oscilloscope!
A differential input is not referenced to ground, but both sides of the input are "floating". It is therefore possible to connect one side of the input to one point in the circuit and the other side of the input to the other point in the circuit and measure the voltage difference directly.
Advantages of a differential input:
- No possibility to create a short circuit to ground through the oscilloscope.
- Only one channel is used to measure the signal.
- More accurate measurement, since only one channel introduces a measurement error.
- The Common Mode Rejection Ratio of a differential input is high. If both points have a relative high voltage, but the voltage difference between the two points is small, the voltage difference can be measured in a low input range, resulting in a high resolution.
There are various applications for oscilloscopes with differential inputs:
Power systems
One application for oscilloscopes with differential inputs is measurements in (switch mode) power supplies, motor drives, frequency inverters. The high common mode voltages and low voltage differences make an oscilloscope with differential inputs the ideal measuring instrument. It also reduces the risk of creating short circuits, resulting in damaged circuits and/or measuring instruments.
Communication buses
Oscilloscopes with differential inputs can also be used very well when measuring at (high speed) digital communication buses like e.g. USB and CAN.
To improve signal integrity, such buses use two differential signal lines and a common ground line. The two signal lines transport the same signal, with the difference that they are each others inverse. This reduces the effect of external influences, since most external disturbances are additive and cause the same offset error in both signal lines. The voltage difference will remain the same, so the actual signal is not affected. To measure the actual signal, a differential input is required.
Audio systems
Another application for oscilloscopes with differential inputs is measuring in professional audio systems. Just as for the digital buses described above, also in professional audio systems two signal lines and a ground line are used to improve the signal integrity (here called "balanced").
The Handyscope HS4 DIFF is supplied among others with a set of four DP-DA10 differential 1:10 attenuators which allow to measure voltages up to 300V.
Fast Continuous Streaming
The Handyscope HS4 DIFF is a high-performance 50MSa/s USB oscilloscope that can be used as a multimeter, spectrum analyzer, data logger/transient recorder or protocol analyzer via the accompanying Windows software. To operate, the oscilloscope must be connected to the USB interface of a PC and the software must be loaded. The device is powered via the USB interface, but can also be connected to an optional external power supply if the computer's USB interface does not provide enough power.
Besides measuring in block mode as oscilloscope, the Handyscope HS4 DIFF is also capable of performing continuous streaming measurements as a data logger. This will create a continuous uninterrupted data stream to the computer. The data can then be displayed on the screen and/or saved to disk.
Combining multiple Handyscope HS4 DIFFs
When one Handyscope HS4 DIFF does not offer enough input channels, the Handyscope HS4 DIFF can be coupled to one or more other instruments. This allows to make a combined instrument which will enable simultaneous measuring on all channels of all combined instruments.
