![]() | The keypad typically provides controls to: • Enter new values directly, such as frequency entries in Hz, kHz, MHz, or GHz. There are two places on the keypad to enter unit terminators when applicable, on left side pop-out that occurs as frequency keypad entries are selected, or on the top right corner drop-down of the entry field. • Drag a parameter value within its settable range using a sliding control. • Increment the parameter value up or down. At each end of the slider are plus (+) and minus (–) controls that increment the parameter value. Most parameters have a fixed increment, such as bandwidth that follows a 1:3:10 sequence and span that follows a 1:2:5:10 sequence. In the case of frequency, you can set a custom frequency step increment value. Once the entry is complete, select the desired unit or select ACCEPT to complete the entry. • Set the parameter to the maximum or minimum possible value. • CLEAR the entire entry. • Left arrow to backspace and delete the entry • CANCEL to terminate any entries made for that particular setting. Note that selecting the "X" to close the keypad is the same as selecting cancel. Selecting CANCEL will restore settings back to the state they were in before the keypad opened, even if changes from the +/- controls are already reflected in the data display. • ACCEPT to operate with the settings displayed on the keypad. |
