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-freque ncy
performance of the probe. With longer lead length, differe n tial noise
induced into the input leads is greater. Also, because of the added
inductance of the leads, voltage me asurements at frequencies above
approximately 10 MHz may not be as preci se. 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.
