LA3000/4000 series or BF6000/7000 series
Used with the LVDS probe set, it can measure LTPI signals.
Using a 2 GHz or 2.4 GHz sample rate, it can measure LTPI signals up to 300 MHz (600 Mbps).
Introduction
LTPI (LVDS Tunneling Protocol & Interface) is an interface protocol designed for transmitting low-speed signals between the HPM (Host Processor Module) and SCM (Server Control Module). It supports multiple channels such as GPIO, I2C/SMBus, and UART, utilizing time-division multiplexing (TDM) over LVDS links to achieve multi-channel transmission.
The GPIO channel includes both low-latency and normal-latency types. The I2C/SMBus channel handles single-controller communication links. The UART channel supports flow control. An OEM channel is also provided for proprietary interfaces, and a data channel supports memory image data transfers.
