Chapter 2 Operating Your Frequency Counter

Using the Menu

•SAVE — Saves a copy of the current user settings in non-volatile memory. Nine sets (0 – 8) can be saved, and set 0 is automatically read on startup. To have the Counter automatically start up with your preferred settings, save these settings in set 0.

•PWR CORR — Activates (or deactivates) the Power Correction function and allows you to edit and select power-correction profiles. Power Correction is used to compensate for losses in the test configuration, such as attenuation resulting from cable impedance.

Each of these menu items is described in more detail on the following pages.

Navigating in the Menu and Changing Settings

When you select the Menu (with the Shift and Menu [Reset/Local] keys), the indicator between the arrow keys flashes to indicate that the arrow keys are now active. Since the Reference Oscillator setting is the first one displayed when you invoke the Menu (unless you’ve used the Menu to change another setting since you turned the Counter on), you don’t have to use the up-arrow key or the down-arrow key to get to it.

When you press the right-arrow key, the flashing annunciator ( ) changes direction, and the current setting for the Reference Oscillator INT (internal) or EXT (external) flashes. This indicates that you can now change this setting. Use either the up-arrow key or the down-arrow key to change the setting.

If there are more than two settings available for the currently selected function, you can cycle through the available settings by repeatedly pressing either the up-arrow key or the down-arrow key. For example, to change the setting for the Baud rate for the serial port, invoke the Menu, and then repeatedly press the up-arrow or down-arrow key until BAUD is shown on the display. Then, press the right-arrow key to select the BAUD option, and press the up- or down-arrow repeatedly until the setting you want is displayed. Finally, press the Enter key to implement your choice.

You navigate to and adjust the remaining settings available in the Menu in the same manner. Each time you modify a setting and press the Enter key, the Menu closes, so you have to reinvoke it each time to change additional settings.
