A.

All input pulses are supplied by a generator having the following characteristics: tr or tf ≤ 1ns, frequency = 1MHz, duty cycle = 50 ± 5%.

B.

RL is 1% tolerance, metal film, surface mount, and located within 2 cm of the D.U.T

C.

CL is the instrumentation and fixture capacitance within 2 cm of the D.U.T. and ±20%. The measurement is made on test equipment with

a –3dB bandwidth of at least 1GHz.
