Operation 4-1
4. Operation
This section presents the control menus and procedures for operating the 4540 Series in the manual mode. All the display
menus that control the instrument are illustrated and accompanied by instructions for using each menu item.
Note
Before any pulse measurements can be acquired with the 4540 Series, a peak power sensor must be
connected from the instrument to the built-in or external calibrator, and calibrated. Making measurements
with a CW sensor can be accomplished without calibration. However, it is recommended that
autocalibration be performed for optimal performance for CW sensors as well. RF voltage probes do not
require autocalibration. For more information about calibration refer to Section 3.5.
4.1 Manual Operation
In the manual mode, the instrument is controlled from the front panel by selecting items from a system of displayed menus.
The menu structure is illustrated in Figure 4-1. To properly input commands and data using these menus, you should be
familiar with the menu conventions described in the next subsection. Subsequent subsections provide detailed instructions.
4.2 Control Menus
The menus that control the 4540 Series begin with a top level that is displayed by pressing the Menu key. There are 2 pages
of top level menus that are selected by the More box in the botton postion. As the More menu key is repeatedly pressed,
page 1 and 2 are alternately displayed and the current page number is displayed in the More menu box.
Several menus lower in the hierarchy also have 2 pages and are controlled and indicated in the same manner. No menus have
more than 2 pages.
The 4540 Series includes the single channel Model 4541 and the dual channel Model 4542. In the 4542 there are two
instances of the Channel menu, designated Channel 1 and Channel 2. For ease of use Channel 1 displayed menus have
yellow characters and Channel 2 displayed menus have blue characters. In the Menu Reference that follows the designation
"Channel 1 | 2" is used to mean that both Channel 1 and Channel 2 (if present) have menus of this structure type except for
different colorization.
Some menus have mode dependent properties. Typically one or more menu boxes in a submenu may change as the
measurement mode is changed from Modulated to Pulse to Statistical. In the Menu Reference that follows these menus are
labelled for mode dependency and shown as parallel paths, one for each mode or mode pair. Menus that are not labelled as
such have no mode dependency.
