Getting Started 1
Keysight 53150A/151A/152A Operating Guide 45
NOTE
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
[a]
connector used for the Channel 2 input on the
Keysight 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.
