Figure 1-1: Isolation scheme of the R&S RTH
The input isolation has several advantages:
● You can measure independently floating signals simultaneously.
● The risk of causing a short circuit while measuring multiple signals is reduced
substantially.
● When measuring signals with different grounds, the induced ground currents
are kept to a minimum.

Measurement Categories
To ensure safe operation of measurement instruments, IEC 61010-2-030 defines
particular safety requirements for testing and measuring circuits. The standard
introduces measurement categories that rate instruments on their ability to resist
short transient overvoltages that occur in addition to the working voltage of the
instrument and can exceed the working voltage many times over.
Measurement categories are distinguished as follows:
● O - Instruments without rated measurement category
