NOTES

CAUTION

Chapter 1 Getting Started

Operating the Counter

The Counter displays CH2 NO SIGNAL or CH1 NO SIGNAL and shuts down all unnecessary circuits when a signal of insufficient amplitude (or no signal) is applied to the corresponding input. This extends the reliability of the affected components, and if the Battery option is installed, extends the length of time the Counter can operate from the batteries.

When the frequency of a signal applied to the Channel 2 input exceeds the maximum rated frequency for the instrument, the Counter displays CH2

TOO HIGH.

The 2.9 mm Planar Crown* connector used for the Channel 2 input on the Agilent 53152A must be handled with care to prevent damage and/or contamination, especially since it acts as a wave guide as well as an electrical connection. Observe the following precautions when handling this connector:

1.If you remove the outer portion of the connector, do not touch the exposed surfaces of either part of the connector with your bare skin or any material that is not intended for cleaning this type of connector.

2.Avoid dropping or striking either portion of the connector.

If the connector becomes contaminated, it can be cleaned with isopropyl alcohol and a lint-free cloth or other suitable cleaning implement.
