Appendix E - AT35 (35V Output Option)
AT35 Description
When the Adjustable Mode is enabled for this module, the outputs will provide an
adjustable output from 5 volts to 35 volts. The pulse width can be set over the
standard range of the unit, but the 35 volt output will self limit to approximately 4
µs with some droop. There is no change to TTL output mode functionality with
this module.
To maintain the highest possible rise time, care must be taken with cabling and
termination. Low capacitance cable and 50 ohm termination will provide the
fastest rise times without overshoot. Faster rise times can be achieved by
increasing the termination resistance, but some overshoot is likely to occur.
While the 35 volt output provides a fast, controlled rising edge, the pulse width
and falling edge are not tightly controlled. Also, when using the 35V mode, the
option will only function if the ‘Polarity’ is set for “Active High”.
