Performance Characteristics (continued)

Trigger System (continued)

I2C Trigger on I2C (Inter-IC bus) serial protocol at a start/stop condition or user defined frame with address and/or data

values. Also trigger on Missing Acknowledge, Restart, EEPROM read, and 10 bit write.

SPI Trigger on SPI (Serial Protocol Interface) data pattern during a specific framing period. Support positive and negative Chip

Select framing as well as clock Idle framing and user specified number of bits per frame.

Duration Trigger on a multi-channel pattern whose time duration is less than a value, greater than a value, greater than a time value

with a timeout value, or inside or outside of a set of time values.

Minimum duration setting: 5 ns

Maximum duration setting: 10 s

Autoscale Finds and displays all active analog and digital (for 54621D/54622D/54641D/54642D) channels, sets edge trigger mode on

highest numbered channel, sets vertical sensitivity on analog channels and thresholds on digital channels, time base to

display ~1.8 periods. Requires minimum voltage >10 mVpp, 0.5% duty cycle and minimum frequency >50Hz.
