Chapter 2 Operating Your Frequency Counter

Using the Menu

Some of the menu items listed on the previous page provide information only (no settings are required [or possible] for these), such as Battery Voltage, Operation Hours, and information that identifies the Counter (Agilent model number, firmware version number, serial number, and installed option codes). These menu options are described in the remainder of this chapter and also in “The Front Panel Menus at a Glance” on page 1-4.

Always terminate each setting you change in a menu option by pressing the Enter key. You can abort any change while the Menu is displayed by pressing the Reset/Local key or the Clear key. Both keys nullify the change you made to the current menu option, but they do not affect any of the other menu options. The Clear key terminates the current menu session, but the Reset/Local key does not.

Reference Oscillator (REF OSC)

By default, the Counter uses its internal 10 MHz reference oscillator (or the optional Oven Timebase, Option 001) as a timebase for all measurements, unless REF OSC is set to EXT, and it detects a 1, 2, 5, or 10 MHz reference signal on the Reference connector on the back panel. If an external reference signal is present, you can force the Counter to use the internal reference oscillator by setting the REF OSC menu option

to INT.

The available settings are EXT (external) and INT (internal), and the default setting is INT.

When REF OSC is set to internal (INT), the Counter outputs a 10 MHz, 1 V p-p signal on the Reference connector on the back panel.
