Figure 3: Twisting the input leads

Extension Leads

The extension leads allow you to reach widely spaced connection
points. Connect the extension leads to the input leads using the
adapters provided. Be sure to use both extension leads so that the
input leads are the same length.

The extension leads, however, do affect the high-frequency
performance of the probe. With longer lead length, differential noise
induced into the input leads is greater. Also, because of the added
inductance of the leads, voltage measurements at frequencies above
approximately 10 MHz may not be as precise. Figure 4 on page 14
shows the affect on HF transient response.

The extension leads do not affect the performance of the probe when
bandwidth is set to 5 MHz.
