USB Handyscope HS6 DIFF the USB oscilloscope 신제품 1 GS/s 샘플링속도 14 bit 분해능 4채널 디퍼련셜 입력quad differential channel High Resolution Oscilloscope.-256M memory , 세이프그라운드기능,슈어콘텍션기능,5년 워런티

This powerful USB 3.0 super speed oscilloscope combines fast sampling up to 1 GS/s with high resolutions of 12, 14 and 16 bit and a large memory of 64 MSamples on all four channels. The oscilloscope supports continuous streaming measurements up to 200 MS/s and can be synchronized with other oscilloscopes using the CMI interface to form a multi channel combined instrument with synchronized time base. The CMI interface is available by default on the Handyscope HS6 DIFF. Optionally, the Handyscope HS6 DIFF can be delivered with SureConnect connection test and resistance measurement on each channel. Also, the Handyscope HS6 DIFF can be delivered with SafeGround option. With SafeGround you can switch the differential inputs of the Handyscope HS6 DIFF into single ended inputs with ground protection. It allows to make measurements using standard attenuating probes and protects the scope when a short circuit to ground is created.

Differential / single ended switchable inputs with SafeGround protection

SafeGroundSafeGroundSafeGround gives the possibility to use the oscilloscope inputs both as single ended and as differential. When SafeGround is active and you accidentally create a wrong connection that causes a short circuit,SafeGround will disconnect the ground of the input channel without damaging the oscilloscope or PC. You can therefore simply switch from a differential input to a single ended input without worrying if anything will damage because of a short circuit current1. The Handyscope HS6 DIFF is the only oscilloscope in the world with this unique SafeGround protection. And as you all know, a connection mistake is easily made, which will now have no more strange and financial consequences because of SafeGround as the short circuit current is limited thanks to SafeGround.

Background: The advantage of an oscilloscope with differential inputs is that there are no connections between the channels and with the ground of the computer. It is therefore not possible to create a short circuit. With SafeGround enabled you can connect a standard 1:10 probe to your channel, this is not possible with a standard differential channel of other oscilloscope manufacturers. Sometimes it is also required to perform a single ended measurement, but then there is a risk of a short circuit.

When you do want to measure with a single ended input, your input is connected to the ground of your oscilloscope and your computer (the alligator clip of your probe is directly connected to ground). The input channels are also connected to each other. When you connect the alligator clip of your probe accidentally to a point in your test subject that is not at ground level but to a point with an elevated voltage, a short circuit current will flow through your probe, oscilloscope and computer. This can cause serious damage to the test subject, the scope and the computer. SafeGround avoids this and safes you a lot of misery. SafeGround can be enabled individually for each channel of the Handyscope HS6 DIFF.

SafeGround current limit menuThe ground current at which the SafeGround protection activates and shuts off the ground connection is adjustable in steps of 10 mA. This allows to use single ended inputs in a situation where the instrument and the device under test do not have the exact same ground level, e.g. due to voltage drop over a ground connection. The small current that then will flow could activate SafeGround. Setting the current limit to a higher value may keep SafeGround from being activated.

When your device under test is very sensitive to damage, the SafeGround current limit can be set to a lower value, to give the highest level of protection.

SafeGround protects your scope, your computer and your circuit under test against accidental wrong ground connections.

SafeGround properties:

  • Low switch off current
  • High speed switching
  • High voltage protection
  • SafeGround on each channel
