Making Measurements

To Control Measurement

Use these two keys to control the measurement of the Counter.
The Run key provides repetitive measurements, whereas the
Run Single/
Stop
Stop/Single key allows you to make one measurement.
With the 10 MHz signal still connected to CHANNEL 2, perform the
following steps so you can better understand the Run and Stop/Single
operations.
The Counter is now making repetitive measurements (continuously
making "live" measurements).
The Counter stopped making measurements. The Gate annunciator is not
lit. Hence, pressing the Stop/Single key while the Counter is making
measurements (in Run) causes the Counter to stop after the measurement
in progress is completed. If you press the Stop/Single key again while the
Counter is stopped, the Counter will make a single measurement and then
stop—the Gate annunciator will light one time, momentarily.
If you press the Stop/Single key while the Counter is stopped and when
the Stats menu item ON SINGLE is set to N, the Counter will make
N measurements and then stop. This enables a set of statistics to be
computed.
While the Counter is still stopped, perform the following step.
The Counter is making repetitive measurements again.
