Part Number: TMDSHVPSFBKIT
Other Parts Discussed in Thread: SFRA, TMS320F28035, TMS320F28027

Hi,

I came up with C2000™ Software Frequency Response Analyzer (SFRA) which was using TMS320F28035 controller. The TMDSHVPSFBKIT is using TMS320F28027 controller. Can SFRA code be used to see the stability for TMDSHVPSFBKIT with TMS320F28027.

Thanks

on PSFB EVM timing for things are being maintained through assembly code, hence for F28027 it is not possible.

There is a possibility to check it with F28035 where CLA is used for the control and SFRA runs on C28x.

Hello Manish,

Could you elaborate on your explanation? Why does maintaining timing through assembly code preclude the use of SFRA? Is it possible to output the data for a frequency response plot though an external D to A and use a frequency response analyzer?

Thanks,

Chuck
