Solution
We could refer to the user manual and specification datasheet of the mentioned product, for example the VirtualBench 8012 on section of
Mixed-Signal Oscilloscope - Analog Channels- Vertical SystemThe value of the maximum input voltage allowed would depends on the
Selected Vertical Sensitivity and
DC Offset Range. Based on these two factors, we could find the maximum input value as:
Maximum Input Voltage = Selected Maximum Range Vpp + Selected Maximum Range DC Offset
Maximum Input Voltage = 40 Vpp +20 V
