Connecting for HCI and Logic Capture | Protocol Solutions User Documentation

The X240/X500/X500e/X700 Logic Analyzer Pods are designed for use with TTL voltage levels, 0 to 3.3 volts maximum. Exceeding the 3.3 volts maximum may damage the pods.

X240 supports up to 2 HCI connections and 16 logic signals using two channel Pods. X500/X500e/X700 - Supports up to 2 HCI connections and 24 logic signals using three channel Pods.

To capture UART, SPI, I2S and logic data at the Bluetooth Host Controller processor interface using a wired connection:

Connect a Logic Analyzer Pod to one of the Oculink connectors on the front panel of the X240/X500/X500e/X700. A Logic Analyzer Pod can be connected to either Oculink connector or two pods can be connected to both Oculink connectors at the same time.

**Logic Analyzer Pods Installed on X500/X500e**

Attach the Flying Lead assembly to the end of the Logic Analyzer Pod. The connector is keyed to ensure proper installation.

UART Capture Configuration

Successful HCI UART capture requires the following Logic Analyzer Pod connections.

Required UART Layer Connections

UART Signal	Logic Analyzer Pod Pin	Comment
Tx	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) TX pin. Only 1 data pin can be used. That pin cannot be used for Rx. Also, select this pin in the Wired tab of the Record Options.
Rx	Any single line labeled Data 0 through Data 7	Connect to the DUT Rx pin. Only 1 data pin can be used. That pin cannot be used for Tx. Also, select this pin in the Wired tab of the Record Options.
GND	Any line labeled Ground	Any of the three Ground pins can be used to connect the DUT ground to the Logic Analyzer Pod.

For more information, refer to the Wired Record Options.

Logic Event Capture Configuration

Successful logic event capture requires the following Logic Analyzer Pod connections. The Logic Analyzer Pod has up to eight pins that can be used for logic event capture.

Logic is internally limited to capturing less than 40,000 transitions per second to prevent sluggishness in WPS real-time captures. These transitions can occur at a rate up to 1 MHz reliably.

Required Logic Connections

Logic Signal	Logic Analyzer Pod Pin
0	Data 0
1	Data 1
2	Data 2
3	Data 3
4	Data 4
5	Data 5
6	Data 6
7	Data 7
GND	Any line labeled Ground

The above are TTL logic inputs for data. Select the corresponding pins in the Wired tab. For more information, refer to the Record Options in the Wired Tab.

For grounding, any of the three Ground pins can be used to connect the DUT ground to the Logic Analyzer Pod.

SPI Capture Configuration

Successful HCI SPI capture requires the following Logic Analyzer Pod connections.

Required SPI Connections

SPI Signal	Logic Analyzer Pod Pin	Comment
SCLK	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) SCLK pin. Only 1 data pin can be used.
MOSI	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) MOSI pin. Only 1 data pin can be used.
MISO	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) MISO pin. Only 1 data pin can be used.
SS/CS	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) SS/CC pin. Only 1 data pin can be used.
GND	Any line labeled Ground	Any of the three Ground pins can be used to connect the DUT ground to the Logic Analyzer Pod.

I2S Capture Configuration

The Inter-IC Sound Bus (I2S) was designed to transport a multi-channel digital audio signal between circuit components on a single printed circuit board.

Successful HCI I2S capture requires the following Logic Analyzer Pod connections.

Required I2S Connections

I2S Signal	Logic Analyzer Pod Pin	Comment
SCLK	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) SCLK pin. Only 1 data pin can be used.
FS	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) FS pin. Only 1 data pin can be used.
DS	Any single line labeled Data 0 through Data 7	Connect to the Device Under Test (DUT) DS pin. Only 1 data pin can be used.
