NOTE

Splitting the signal using the SMA T does not preserve the 50 W

environment. As a result, you will see aberrations of the signal due

to this impedance mismatch. The aberrations are of no conseĆ

quence for the examples. However, to obtain accurate measureĆ

ments, be sure you split signals using a 50 W power divider to

match the impedance of the test setup.

CAUTION

To prevent damage to the inputs do not attempt to measure any

signals greater than 3ĂV peak-to-peak with the TDS 820 with

Option 1D (6ĂV peakĆtoĆpeak with the standard TDS 820).
