Figure 8 shows a series of measurements taken from the line simulator when the cable resistance has been increased to 500 Ohms.
The results are satisfactory and the increased variation of the data being caused in part by the thermal effects on the various components of the circuit.

Figure 9 shows a series of measurements when the line simulator resistance is increased to to 2 K Ohm ie 20 times that of a normal 4 Km circuit using category 5 cable. The results show that the VibWire-108 maintains its reading even when a sensor cable deteriorates considerably as occurs in most systems over time.
Figure 7 shows a sample of results taken using a sensor cable length of only 50m. Clearly shown are the 0.1 Hz steps that is the maximum resolution that the instrument can resolve.
The measurements are very stable and suitable for any application.
