My goal is to measure the concentration / quality of AdBlue liquid using a single ultrasonic transducer operating in a pulse-echo mode (transmit signal -> bounce off a fixed reflector -> receive echo on the same transducer). Since standard flow-metering examples rely on a dual-transducer bi-directional setup (upstream/downstream), I would like to get step-by-step guidance on setting up a single-transducer pulse-echo configuration: 1. Hardware Connections: Which specific channel header/pins should I use for connecting a single transducer for both pulse transmission and echo reception? Are any jumper configurations required on the MSP430FR6043EVM? 2. USS GUI Configuration: How should I configure the System Configuration in the USS Design Center GUI for single-transducer operation (e.g., channel selection, gain settings, and capture window timing for liquid reflection)? 3. Software / USS Library Configuration: How can I adapt the demo firmware (or USS Library parameters) in Code Composer Studio (CCS) to execute a single-ended pulse-echo capture sequence without expecting a second channel? Thank you for your guidance and recommendations.

However, the only document currently available on your website is the TX08D_Datasheet_Short_sbasaw7a.pdf. Are there any other more detailed technical documents (such as a full datasheet) for the TX08D chip? Additionally, is the schematic for the TX08DEVM available? We would like to obtain these resources to facilitate our upcoming custom system PCB design.https://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1677932/tx08devm-tx08devm-question/6468000Mon, 31 Aug 2026 17:27:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:d81957d1-bf0f-44fc-a1c2-e81656052a8eRoshan DivakarHi, no we don't have any reference design for connecting TX08D to a actual transducer. Ideally, our customers build their own system PCB which has the relevent HV Muxes and switches requried to map the TX08D channels to the transducer elements. As such, there is no damping or protection network requried. Regarding matching, the circuit will be highly dependent on the transducer load, and we don't have much exertise in the tuning circuits for the transducer. The TX08D has receive outputs which are the outputs of T/R Switch that can be connected to the AFE inputs.https://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1677932/tx08devm-tx08devm-questionMon, 31 Aug 2026 10:25:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:f1de18f7-ba9d-42a1-bd25-9970f1ec954cyin luPart Number: TX08DEVM Other Parts Discussed in Thread: TX08D , Does TI provide a recommended reference design or interface/adapter board for connecting TX08D to an actual piezoelectric probe? For real transducer evaluation, should we design a separate TX08D board based on the EVM schematic rather than modifying the TX08DEVM? What output damping/matching/protection network does TI recommend between TX08D and a 4 MHz piezoelectric array element? How should the TX08D T/R switch interface with the receive AFE in a pulse-echo system?Also, please share the detailed specs of the main chip and the schematics for the TX08DEVM board so we can use them for future application development."TX08DTX08DEVMTest & Measurementhttps://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1676995/tx08devm-tx08devm-troubleshootingThu, 27 Aug 2026 01:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9ff13c61-4f23-4622-b772-bcf2b3d1b8adyin luPart Number: TX08DEVM Other Parts Discussed in Thread: TX08D , We are currently debugging the TX08D using the TX08DEVM. The EVM powers up normally, the USB/GUI connection works correctly, and the initial diagnostics pass. However, when following the TX08DEVM User Guide (SBAU469) to generate both the built-in LIN waveform and a custom waveform, there is no LIN output, and the following errors are reported: TX_START_ERR LONG_TRAN_ERR_LIN We have attached a short document including our test procedure, GUI settings, and oscilloscope waveforms. Could you please help us check whether there is any issue with the configuration, synchronization/trigger settings, or operating sequence? As we will continue developing with the TX08D, if possible, we would also appreciate being connected with a TI China technical support engineer/FAE. It would be very helpful if we could add each other on WeChat and create a small technical discussion group with our engineers for further debugging. Thank you very much for your support.

Based on the mass‑production experience together with our customers, we have included the transducer recommendations in the document FAQ on ultrasonic sensing technology (as shown below), Audiowell and Jiakang transducers are common, recommended choices and typically pair well with MSP430FR604x devices , the links in the document may not work but you can use the links provided below to view the recommended models. These models might be a bit outdated and of course, other new transducers from these recommended manufacturers with similar specifications can also be used.
