| General Specifications |
| Model |
I2Cbus TD and I2Cbus TDME |
| Definition |
| Source Setup |
Select Source for Clock and Data |
| Trigger Capability |
| Format |
Hexadecimal or Binary. ADDRESS and DATA can be set up with different formats |
| Trigger Setup |
Trigger on START, ReSTART, STOP, Missing ACK, ADDR, DATA, ADDR+DATA, ADDR+DATA FRAME LENGTH, EEPROM DATA TRANSFER |
| ADDRESS Setup |
Specify one ADDRESS with condition of "=".
7 or 10 bit ADDRESS supported with full Read, Write, or R/W="Don’t Care" on both 7 and 10 bit ADDRESSes.
Choose to Trigger on address values that include/don’t include R/W bit in address value. |
| DATA Setup |
ADDRESS+DATA Trigger Type:
Hexadecimal: # Data Bytes = 0 to 12. Data can be defined by nibble.
Binary: Any combination of 0,1, or X for 1-96 bits
Data pattern can be set to start at any location in the 12 Byte / 96 bit sequence.
ADDRESS+ DATA FRAME LENGTH Trigger Type: # Data Bytes = 0 to 2047. EEPROM DTA TRANSFER Trigger Type: # Data Bytes = 0 to 12. Data can be defined by nibble. Data pattern can be set to start at the beginning of any byte in an up to 2048 byte sequence. |
| DATA Conditions |
<=, <, =, >, >=, < >, IN RANGE, OUT OF RANGE, or DON’T CARE |
| ACK Conditions |
For any ADDR, ADDR+DATA, ADDR+DATA FRAME LENGTH, or EEPROM DATA TRANSFER setup, select an ACK Condition of ACK, NO ACK, and DON’T CARE. |
| Bit Rates |
Full range over I2C specification for Standard, Fast, Fast-Mode Plus, and High-Speed modes. Auto-detected |
| Trigger Input |
Any analog Channel or Digital input, or the EXT input. Clock may be input to EXT to conserve available analog Channels. |
| Decode + Search Capability |
| Format |
Hexadecimal, Binary, ASCII |
| Decode Setup |
Threshold definition required. Default is to Percent amplitude. Choose to Decode address values including/not including the R/W bit in address value. |
| Decode input |
Any analog Channel, Memory or Math trace, and any Digital trace. Clock channel may be turned OFF and data will still decode (reduces screen clutter) |
| No of Decodes |
Up to 4 buses may be decoded at one time. In addition, zooms can be displayed (with decoded information). |
| Visual Aid |
Color Coding for FRAME, START/ReSTART bit, ADDR, R/W, DATA, ACK, NACK, and STOP bit. Decode information is intelligently annotated based on timebase setting, and overlaid on acquired waveform. |
| Table Configure, Export Table |
Display 1 to 20 rows of decoded information for up to 4 different protocols or decodes in time order in a single table. Displayed information includes Index, Timestamp, and other various protocol-specific information. Table permits scrolling, touch to zoom, export to .csv file, and special display of long data or other patterns. |
| Pattern Search |
Search for Previous or Next ADDRESS, PACKET, or DATA in hexadecimal format. |
| Model |
SPIbus TD and SPIbus TDME |
| Definition |
| Source and Protocol Setup |
Select Source for Clock, Data, and Chip/Slave Select (Chip/Slave Select not required for SIOP or SSPI types). Select SPI Type (SPI, SIOP, SSPI, or SPI-DDR). SPI Type CUSTOM is also available in the decoder. For SPI or SPI-Custom, select CPOL (Clock Polarity 0 or 1) and CPHA (DATA Polarity 0 or 1) (SIOP permits CPOL selection of 0 or 1, but CPHA =1; SSPI CPOL=1, CPHA=1; SPI-DDR does not have CPOL or CPHA selection). Select DATA = MSB or LSB. Select InterFrame Setup to Auto or Manual. |
| Trigger Capability |
| Format |
Hexadecimal or Binary |
| Trigger Setup |
Trigger on DATA for any of the five SPI Modes with either MSB/LSB and with or without Slave Select. InterFrame Setup permits user-definition of expected maximum time between clock bits so as to permit triggering with CLOCK and DATA signals in the absence of a CHIP/SLAVE SELECT signal (SIOP or SSPI). Typically, the InterFrame AUTO default of 4x a bit length is sufficient, but this can be set to any value. |
| DATA Setup |
Hexadecimal:
# Data Bytes = 0 to 12. Data can be defined by nibble.
Binary: Any combination of 0,1, or X for 1-96 bits
Data pattern can be set to start at any location in the 12 Byte / 96 bit sequence.
InterFrame Time Setup is available for SIOP, SSPI, and SPI-CUSTOM Types. This permits user-definition of expected maximum time between clock bits so as to permit decoding in the absence of a Chip/Slave Select signal. The InterFrame AUTO default of 4x a bit length is typically sufficient, but this can be set to any value up to 10 seconds. It also enables definition of multiple SPI (any Type) byte packets into a single long message package of multiple SPI Data bytes, over which up to 12 Data Bytes can be defined for triggering (as described above). |
| DATA Condition Setup |
<=, <, =, >, >=, <>, IN RANGE, OUT OF RANGE, or DON’T CARE |
| Bit Rates |
Any, up to 25 Mb/s (typical).
Auto-detected from clock signal |
| Trigger Input |
Any analog Channel or Digital input, or the EXT input. Clock or Chip/Slave Select may be input to EXT to conserve available analog Channels |
| Decode + Search Capability |
| Format |
Hexadecimal, Binary, ASCII |
| Decode Setup |
Threshold definition required. Default is to Percent amplitude.
Choose to Decode address values including/not including the R/W bit in address value. |
| Decode Input |
