The Coordinated Connection Of A Remote Voltage Source Through A Pair Of Long Line With A Wave Resistance Zw With Matching On The Signal Source Side - L-Card ADC Series User Manual

6.1.9. The coordinated connection of a remote voltage source through a pair of long
line with a wave resistance Zw with matching on the signal source side

R – internal (output) impedance of the signal source.
BH
R – balancing resistor on the signal source side.
The cable must be paired (shielded twisted pairs) with wave resistance of wire pairs Zw.
Below is a practical case where a broadband operational amplifier acts as a remote voltage source (providing
a low-impedance voltage output in the frequency band up to 10 MHz).
