RS-232/UART specifications and characteristics

UART protocols supported RS-232

RS-422 up to 10 Mbp/s, differential probing recommended.

RS-485 up to 10 Mbp/s, differential probing recommended.

Other UART interfaces which admit to user-specified parameters

available in the application.

The application relies on probing and trigger/measurement thresholds

to properly condition the signal for triggering and decode.

The Infiniium 90000 Series requires E2697A hi-pod adapters for probes

with 1 MΩ impedance.

Tx and Rx source Analog channels 1, 2, 3, or 4

Any waveform memory

Auto setup Automatically configures trigger levels, measurement thresholds, memory depth, sample

rate, trigger and holdoff for proper decode and triggering.

Decode word size User-selectable: 5, 6, 7, 8, or 9 bits

Parity: odd, even, none

Decode bit order User-selectable: LSB or MSB

Supported baud rates User selectable: 1.2 kb/s up to 10 Mb/s

Idle Polarity User selectable: low or high

Triggering

(software-based)

User selectable: transmit or receive

User selectable data length: 1 to 13 words (each word takes 2 trigger symbols)

Word size selectable from 5 to 9 bits

Enter trigger in HEX, binary, decimal or ASCII
