Subject: T9 System changed to version 8 

I have changed the T9 system to be using Version 8.

Tests using the detector and pulser seem to be ok.

Transmission to the Merge and Merging operating ok

Shaping time 8uS and threshold 64.

Note:-

The Leading Edge Discriminator has changed in Version 8 and is a true implementation of a Leading Edge Discriminator. With hysteresis which requires the input signal to go below the threshold before allowing another trigger.

The Delay setting on the LED web page is removed.

The LED web page is aware of the version being used ( shown at the top of the page ) as the Threshold for the LED is an ADC value ( 0 to 16383 ) rather than a difference from the current baseline.

For a positive waveform where the baseline is expected to be about 8192 a value of 9000 will potentially give a trigger.

For a negative waveform where the baseline is expected to be about 8192 a value of 7000 will potentially give a trigger.

Example window attached.

I would value feedback.
