• 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.
