User Manual

The oscilloscope will trigger on the clock edge for the Ack bit after the trigger event

is found. This data byte does not need to occur directly after the control byte. The

oscilloscope will trigger on any data byte that meets the criteria defined by the Byte

Length and Data1 softkeys during a current address read, a random read, or a

sequential read cycle.

 7-bit Address & Data Condition - The oscilloscope triggers on a read or write frame in 7-

bit addressing mode on the 17th or the 26th clock edge if all bits in the pattern match.

For triggering purposes, a restart is treated as a start condition:

Figure 71 - 7-bit address and data condition trigger (17

clock edge)

Figure 72 - 7-bit address and data condition trigger (26th clock edge)

 To set the oscilloscope to trigger on a 7-bit address read or write frame condition or

a 10-bit read or write frame condition:

a) Press the Addr softkey and turn the Universal Knob to select the 7-bit or 10-bit device

address.

You can select from an address range of 0x00 to 0x7F (7-bit) or 0x3FF (10-bit)

hexadecimal. When triggering on a read/write frame, the oscilloscope will trigger

after the start, address, read/write, acknowledge, and data events occur. If "don't

care" is selected (0xXX or 0xXXX) for the address, the address will be ignored. The

trigger will always occur on the 17th clock for 7-bit addressing or 26th clock for 10-

bit addressing.

b) Press the Data1 or Data2 softkey and turn the Universal Knob to select the 8-bit data

pattern on which to trigger. You can select a data value in the range of 0x00 to 0xFF
