XPLA Programmer - What should the ATE vector clock speed for TCK be?

Urgency: Standard

General Description:
What clock speed should be used to run ATE vectors?


We generate our program and init pulses by requesting a delay that is based
upon a number of TCKs during programming. This value is set at an arbitrary
10,000 clock pulses (for at least a 10ms delay). Our devices require a 10 ms
program pulse; therefore, TCK generated by the ATE setup can not be faster
than 1 MHz.
