Chapter 2 Operating Your Frequency Counter
Setting the Resolution and Measurement Rate

Setting the Measurement Rate

The measurement Rate setting determines how frequently the counter
initiates measurements. Since the actual measurement rate is also
affected by the resolution setting and the signal quality, as mentioned
earlier, the available rate settings (FAST, MED, and SLOW) do not equate
to a fixed number of measurements in a given amount of time.The HOLD
setting turns off automatic measurements, so that a single measurement
is made each time you press the Reset/Local key.

Rate Setting Example

1 Press the Rate key to enter the rate-setting mode.
Freq
Offset
Rate The current rate setting is displayed (the current value and the indicator
between the arrow keys are flashing to indicate that you can use the up-
On/Off
and down-arrow keys to change the setting).
Clear
2 Press the up-arrow or down-arrow key to decrease or increase the
measurement rate.
You can press these keys as many times as necessary to locate the setting
you want to use. The available resolution settings are FAST, MED, SLOW,
and HOLD.
3 Press the Enter key to activate your setting and exit the rate-
setting mode.
The setting you chose is now in effect. The measurement rate is adjusted
accordingly; you can observe the effect on measurement speed by
monitoring the flash rate of the Gate indicator. There is no annunciator
on the display for the rate setting, unless you set the rate to HOLD.
4 If you set the rate to HOLD, press the Reset/Local key to initiate
a measurement.
The Counter displays the MEASURING message while it computes the
Hold
measurement, and then displays the result. Press the Reset/Local key
again each time you want to take an additional measurement.
