loss characteristic, and a loss of 17 dB at 1/2 the
serial clock frequency.
For example: 175 meters (574 ft) of Belden 8281 low loss 75 cable.
12. 75 Terminators
4 required. 3 should be end-line, 2 of which are for use on the Serial Inputs,
and 1 should be a standard, for use on the External Reference Input. The
fourth one should be a feed-through type.
For example:
- 75 End–line Terminations, 26 dB to 300 MHz (Tektronix Part
No. 011–0163–00)
for use on Serial Inputs.
1
- 75 End-line Termination (Tektronix Part No. 011–0102–00) for use on the
