At that frequency cable length there won't be much in the way of attenuation. Are the "dual conductors" twisted or are they just side by side like speaker wire? The total delay for a round trip is likely to be less than 10 nsec. so the reflection situation will be hard to see on a scope. How were you planning to measure the voltage?I am trying to measure the voltage at the output. The signal is a 230kHz sine wave. The cable is a dual conductor eco cable by Alphawire. The cable is approx 3 feet long.
1. Alpha part number?It is twisted. I tried to check for a reflection situation, but yeah, you cannot see it. I took the simplest approach at first...put a scope probe at the output and measure away. The measurement I took had a drop, but I am guessing that it is due to the out impedance of the frequency generator in the input impedance of the scope and probes causing a divider?
1. 783421. Alpha part number?
2. Signal generator output Z?
3. 'Scope probe input Z?
true...I think at this point, the capacitance of the cable probably has the biggest impact....For all practical purposes 3 feet is not a transmission line for a 230 kHz sine wave .
That's too low a resistance for a 10:1 probe and too low a capacitance for a 1:1 probe.3. 12 pF and 1Mohm
Can you elaborate?That's too low a resistance for a 10:1 probe and too low a capacitance for a 1:1 probe.
