Siglent launched handheld digital oscilloscope SHS800 series. There is a big price gap between the SHS1000 series and the SHS800 series. With the same 1G sampling rate, 60/100MHz bandwidth, 2M memory depth, why there is a price gap between these two series handheld oscilloscope? In fact, the answer is reflected in the name: Isolation Handheld Oscilloscope SHS1000 series and Handheld Oscilloscope SHS800 series, the key lies in the word “isolated” Isolation security level between the oscilloscope channels: CATII 1000V, CATIII 600V Security level between the oscilloscope channels and earth: CATII 1000V, CATIII 600V From the description above we can see that SHS1000 embodies the "floating" and "isolation" concept particularly, but the SHS800 is not. The traditional oscilloscopes are the structure shown in the right figure. In this structure, in multi-channel measurements, all the input signals must have the same voltage reference, and the shared default reference is the "earth". If there is no differential preamplifier or external signal isolator, this traditional desktop oscilloscope is not suitable for floating measurements. Comparing the isolation oscilloscope and the traditional oscilloscope, the isolation oscilloscope’ There is not real ground reference level of the handheld oscilloscope, so as shown above, ground reference for the various modules belongs to virtual ground, and reference voltage of the oscilloscope channel directly relies on input voltage of the probe’s clip. Comparing SHS1000 and SHS800, the main difference lies in function “isolation” When it comes to isolation, let me introduce the definition rules of CAT (overvoltage category), as shown below: Operating voltage Peak instantaneous voltage Test resistor CAT I 600V 2500V 30Ω CAT I 1000V 4000V 30Ω CAT II 600V CAT II 1000V 6000V 12Ω CAT III 600V CAT II 1000V can withstand instantaneous high-voltage 6000V. Although SHS800 is lacking in function “isolation” About SIGLENT: Siglent is a national high-tech company, concentrates on R&D, sales, production and services of measurement products.
