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.

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.
