Operating the Counter

Measuring Frequency

The following diagram shows the basic sequence to use to make a frequency measurement using Channel 1. This example assumes that the Counter is on and has completed the Self Test. For the purposes of this example, use the 10 MHz reference output on the Counter’s rear panel as a signal source for input to Channel 1.

The same procedure applies to making a basic frequency measurement on

 

Channel 2. However, since Channel 2 is automatically selected when you

 

turn on the Counter, the channel-selection step is unnecessary (unless you

 

previously selected Channel 1).

 

 

CAUTION

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.
