PARAMETER MEASUREMENT INFORMATION (continued)

A.

All input pulses are supplied by a generator having the following characteristics: tr or tf ≤ 1 ns, frequency = 500 kHz,

duty cycle = 50

± 5%.

B.

C1, C2, and C3 include instrumentation and fixture capacitance within 2 cm of the D.U.T. and are

±20%.

C.

R1 is a metal film, surface mount, and 1% tolerance and located within 2 cm of the D.U.T.

D.

The measurement is made on test equipment with a –3 dB bandwidth of at least 1 GHz.
