Signal Generator Overview
Front Panel
Chapter 16
1. Display
The LCD screen provides information on the current function. Information can include status
indicators, frequency and amplitude settings, and error messages. Labels for the softkeys are
located on the right-hand side of the display. For further description of the front panel
display, refer to “Front Panel Display” on page 11.
2. Softkeys
These softkeys activate the function indicated by the corresponding label on the display.
Corresponding menu labels appear directly to the left of each key.
3. Knob
Rotating the knob increases or decreases a numeric value or changes a highlighted digit or
character. You can also use the knob to step through lists or select items in a row.
4. Amplitude Key
Pressing this hardkey makes amplitude the active function. You can change the RF output
amplitude or use the menus to configure amplitude attributes such as power search, user
flatness, and leveling mode.
5. Frequency Key
Pressing this hardkey makes frequency the active function. You can change the RF output
frequency or use the menus to configure frequency attributes such as frequency multiplier,
offset, and reference.
6. Save Key
This hardkey accesses a menu of choices enabling you to save data in the instrument state
register. The instrument state register is a section of memory divided into 10 sequences
(numbered 0 through 9) each containing 100 registers (numbered 00 through 99). It is used to
store and recall frequency, amplitude, and, for PSG-A Series signal generators, modulation
settings. It provides a quick alternative to reconfiguring the signal generator via the front
panel or SCPI commands when switching between different signal configurations. Once an
instrument state has been saved, all of the frequency, amplitude, and modulation settings can
be recalled with the
Recall hardkey.
