Operating the Counter

1-18 Operating Guide

NOTES 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.

CAUTION 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.
