Operating the Counter

Measuring Power (Channel 2 Only)

The Agilent 53150A/151A/152A Counter can measure signal power (in the same frequency ranges as for frequency measurements) on Channel 2. The example procedure for measuring power in the following diagram assumes that the Counter has previously been set up to measure a 25 GHz input on Channel 2.

When the power of a signal applied to the Channel 2 input exceeds the maximum rated power for the instrument, the Counter displays HI.

The Channel 2 input path circuits contain sensitive GaAs semiconductors. To prevent damage to these components, always adhere to standard ESD (Electro-Static Discharge) prevention procedures, and ensure that the maximum power specification for this channel (+27 dBm) is not exceeded.
