Tobo: the HV-pulser

What does it look like?

Information

What is it supposed to do?

The aim of this echOmod is to get the HV Pulse done.

How does it work: block diagram

• ITF-9_Pon->HV7360
• ITF-10_Poff->HV7360
• ITF-2_VDD_5V->R05-100B->HV7360->ITF-mET_Transducer
• ITF-mET_Transducer->ITF-mET_SMA
• ITF-mET_Transducer->ITF-18_Raw

About the module

Pros

• Only needs 5V and 3.3V
• Energy use : TODO
• Using any logic voltage for PulseOn and PulseOff is a pplus
• Can use the potentiometer to control the tension
• Modularity through jumpers and SMA

Cons

• Takes a lot of space because of the modularity. SMA, jumpers and pots could be removed.

• Little flexibility from the use of ICs.

• There's no impedance matching for the pulser to the transducer, could be better.

Constraint and limits

The pulser-control

Output signal

With and without a pulser - no impedance adaptation

Look of the schematics

and a link to it (plus some bonus with the map).

Source files include Altium and KiCad - along with the BOM.

Availability of HV7360

• Some issues with the availability of the HV7360, living its end of life. The latest version of Altium and Kicad source files should show the new HV7360 CABGA.
• However, this latest should be available officially in Jan 2017.

TODO

DONE

• Writing specs
• HV7360 has been updated
• Sending microcircuits to Edgeflex
• Agreeing on the strips/tracks
• Defining the ICs to use to pulse
• Getting schematics
• Publishing schematics
• Receive the module
• Test it with different transducers
• Publish the sources in KiCAD
