10:1 Divider
10:1 Divider
The 10:1 divider fits over the tip of the probe and provides the following changes to the probe’s
operating parameters:
•
Increases (by a factor of 10) the input voltage at which 1 dB compression occurs.
•
Decreases the input capacitance without changing input resistance, thereby decreasing capacitive
loading.
Two or more dividers may be cascaded to provide higher divide ratios.
Operating Characteristics
Inspection
Make sure the tip is not bent or discolored. Periodically inspect the barrel of the probe receptacle,
making sure it is clean and free of grit. Clean the receptacle with clean compressed air.
When cascading 10:1 dividers, periodically inspect and clean the exterior of the metal sleeve.
