2 Operating Your Frequency Counter
78 Keysight 53150A/151A/152A Operating Guide
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.
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- and
down-arrow keys to change the setting).
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.
