13.3 I²C (option R&S MXO4-K510)
The Inter-Integrated Circuit is a simple, low-bandwidth, low-speed protocol used for
communication between on-board devices, for example, in LCD and LED drivers,
RAM, EEPROM, and others.
Required options and equipment
For performing I²C decode measurements, you need the following equipment:
●
MXO 4 with 2 available channels. The channels can be a combination of the follow-
ing:
– Analog channels (C1-C4)
– Logic channels (D0-D15) (requires option R&S MXO4-B1)
