2 In the Search Menu, press the Search softkey; then, turn the Entry knob to select
the serial slot (Serial 1 or Serial 2) on which the I2C signal is being decoded.
3 Press Search; then, select from these options:
• Missing Acknowledge — finds SDA data is high during any Ack SCL clock bit.
• Address with no Ack — finds when the acknowledge of the selected address
field is false. The R/W bit is ignored.
• Restart — finds when another start condition occurs before a stop condition.
• EEPROM Data Read — finds EEPROM control byte value 1010xxx on the SDA
line, followed by a Read bit and an Ack bit. It then looks for the data value
and qualifier set by the Data is softkey and the Data softkeys.
• Frame(Start:Address7:Read:Ack:Data) — finds a read frame on the 17th clock
edge if all bits in the pattern match.
• Frame(Start:Address7:Write:Ack:Data) — finds a write frame on the 17th clock
edge if all bits in the pattern match.
• Frame(Start:Address7:Read:Ack:Data:Ack:Data2) — finds a read frame on the 26th
clock edge if all bits in the pattern match.
• Frame(Start:Address7:Write:Ack:Data:Ack:Data2) — finds a write frame on the
26th clock edge if all bits in the pattern match.

Setup for SPI Signals
Serial Peripheral Interface (SPI) signals setup consists of connecting the
oscilloscope to a clock, MOSI data, MISO data, and framing signal, then setting
the threshold voltage level for each input channel, and finally specifying any other
signal parameters.
To set up the oscilloscope to capture SPI signals, use the Signals softkey which
appears in the Serial Decode Menu:
1 Press [Serial].
2 Press the Serial softkey, turn the Entry knob to select the desired slot (Serial 1 or
Serial 2), and press the softkey again to enable decode.
3 Press the Mode softkey; then, select SPI trigger type.
