3.2 KEY FUNCTION SUMMARY
Table 3-1 references each operating key or connector to a callout in Figure 3-1or 3-2 and briefly describes the key
function
50 MHz Calibrator 1 The output of the built-in 50MHz programmable calibrator is available
from a Type-N connector located on the front or optionally on the rear
panel of the instrument. This calibrator is used to automatically calibrate
sensor offset and linearity, and can also be used as a general purpose
calibration signal source.
Display 2 The 4530 Series RF Power Meter uses a 160x80 pixel graphic liquid crystal
display module with a switchable LED backlight. The display contrast
may be adjusted by holding down the ESC key while pressing the

< and > Keys 3 Used to navigate between levels of the menu structure while in Menu
Mode or Zero/Cal Mode and to select individual editing numeric param-
eters. In Text Mode and Graph mode these keys can be used to switch
the display between channels. In Text or Graph Edit Modes, the < and >
keys scroll the header line left or right through a list of editable param-
eters.
∧ and ∨ Keys
4 Used to scroll up and down through a list of items when in Menu Mode
or Zero/Cal Mode. They are also used to increment and decrement pa-
rameter values or individual digits when editing. In certain Text Modes,
these keys can be used to page up or down through a series of measure-
ment screens.
(Key Repeat) --- Note - If the
∧ or ∨ key is pressed and held when incrementing or
decrementing a variable, it enters auto-repeat mode. At first, there is a
short delay, and then the number begins to increment at a slow rate. The
increment rate accelerates to a medium rate after 2 seconds, and to a high
rate after 7 seconds. To select and hold the medium repeat rate, double-
click the key - releasing and immediately pressing the key will inhibit the
high-speed auto-repeat rate so the value doesn’t “run away” just as the
desired number is being approached.
Enter/Run Key 5 Activates a menu selection or completes update of a parameter in Menu
Mode or Zero/Cal Mode. Pressing Enter/Run while stopped in Text
Mode or Graph Mode will start (or restart) the measurement process.
ON/STBY Key 6 Switches the power meter between on and standby modes. When in
standby, some circuitry remains powered to reduce drain on the battery
used to maintain the non-volatile memory.
