■
A 3-ft., 100 ohm BNC-to-Bantam cable
This is a custom cable that can be ordered directly from Digital
Lightwave (Part Number 002727). It is used for Frequency Adjustment
calibration.
■
A 3-ft., 75 ohm BNC-to-Bantam cable with 1.0
µ
F capacitor
This is a custom cable that can be ordered directly from Digital
Lightwave (Part Number 001901). It is used for DS1 calibration.
