NOTES: A. The pulse generators have the following characteristics: Z
O
= 50 Ω, t
r
= 10 ± 5 ns, t
f
= 10 ± 5 ns, t
pd1
= 500 ns, PRR ≤ 1 MHz,
t
pd2
= 1 µs, PRR ≤ 500 kHz.
B. Strobe input pulse is applied to Strobe 1G when inputs 1A-1B are being tested, to Strobe S when inputs 1A-1B or 2A-2B are being
tested, and to Strobe 2G when inputs 2A-2B are being tested.
C. C
L
includes probe and jig capacitance.
D. All diodes are 1N916.
