E4887A-10x Series Cable Emulators
The E4887A-10x series offers different cable emulators for compliant jitter
tolerance testing. Each cable emulator is packaged and has 3.5 mm (f) connec-
tors for TMDS clock and all three TMDS data lanes. Each lane is differential
and matched in length.
The cable emulators are offered in 3 versions:
E4887A-101 CTS 1.3 low frequency ≤ 74.25 MHz
E4887A-102 CTS 1.3 high frequency > 74.25 MHz
E4887A-103 CTS 1.3 compliant passive EQ cable emulator
The E4887A-101 emulates a CAT 1 reference cable, while E4887A-102
emulates a CAT 2 reference cable.
