The cursor buttons control the movement of the cursor on the display. When a parameter is opened for editing, a cursor highlights the open parameter. Each time the right or left pad is pressed, the cursor moves left or right by one digit. The up or down pad can then be used to increase or decrease the value of the parameter. The unit size of the increase or decrease that occurs each time the up or down pad is pressed is determined by the cursor position.
In addition, when editing frequency, power level, and time parameters, the incremental size can be set to a specific value. Once set and activated, each time the up or down pad is pressed, the parameter's value increases or decreases by the set amount. The cursor does not appear with the increment mode is toggled ON. See INCREMENT Menu.
Editing the Parameter
To modify a numeric parameter setting that is displayed on a menu or annotated field, press the unit to make it active. Edit the parameter by using the numeric keypad, arrow buttons, or rotary data knob to change the value as shown in Figure: Edit Parameter Display.
Use a termination buttons to close the window. The termination buttons are described in
Termination buttons are used to terminate keypad data entries and change the parameter values in memory. As shown on the left, termination soft buttons are located on the right side of the menu display. If the entered value is outside the allowable range of the open parameter, an error message will be displayed along with an audible “beep.” This example displays frequency termination buttons in the left-side settings menu.
Frequency:
GHz / MHz / kHz / Hz / mHz
Level:
dB / dBm / dB/mV (in log power level mode)
Time:
Sec / ms / ms / ns
BACKSPACE
The back space button is used to correct keypad data entry errors by deleting the last number, “–”, or decimal point entered.
CLEAR
When a parameter is open for editing, the clear entry button is used to clear the parameter entry.
ESC
Clears the data entry and the previous parameter is displayed.
Entering a New Value
To change the current value of a parameter by entering a new value for the parameter, use the data entry keypad and termination buttons.
Press the parameter to be edited. Enter the new value for the parameter, then press the appropriate terminator button. If the entered value is outside the allowable range of the open parameter, the entry is not accepted and the previous value for the parameter is displayed.
Numeric Entry Buttons
The numeric keypad provides for direct entry of numerical values. The +/– button changes the sign of the numerical value during data entry. The SELECT button enters the value that is currently displayed in the parameter entry field.
Invalid Entries
When setting parameters or entering other types of data, if an entry is out of range or is otherwise invalid, an audible beep will be sound and may provide a message indicating a invalid range. In this case, clear or cancel the entry and enter a valid value or change the units by using either the drop-down selection next to the data entry window, or with the unit terminators to the left of the keypad.
Using a Set Increment
When editing frequency, power level, and time parameters, you can increase or decrease the parameter's value by a set amount each time the arrow buttons are pressed or the rotary data knob to increase or decrease the value. For instructions on setting the increment size, refer to INCREMENT Menu.
