Hi,
we followed your advice and tested the pga450 with dual transducers functioning as a separate receiver\transmitter (our main goal is to decrease the minimum measurable distance to ~5cm)
we did reach a minimum of ~10cm in a test in which:
- Configured 2 58kHz transducers to function as separate Rx\Tx.
- Jumpers JP4 and JP3 are removed and jumper JP5 is installed.
- Blanking timer is 0.
- XFMR config is set to single-ended.
- On firmware side :
- EN_CTRL register value is changed from 0x85 to 0x82 to disable the decay monitoring function
and to enable bursts on OUTB in single-ended.
- Cancel while loop to indicate saturation decay.
The thing is that I can still see saturation in the first ~15 fifo samples and I’m not sure it makes sense as in theory, saturation time should not exist on the receiver side. Am I wrong to assume that?
Thanks!
Guy
