Other Function Selection Keys
There are several functions that you access directly from front-panel keys
(not from within the Menu). These functions are:
• Measurement Rate (Rate key)
• Number of Averages (Avg key)
• Display Resolution (Resol key)
• GPIB Address (GPIB key)
Use the Selection keys in the manner described earlier in this chapter
(see “Numeric Entry” and “Changing States”) to adjust the settings for
these functions. Detailed procedures for using the Rate, Avg, Resol, and
GPIB keys are provided later in this chapter.
There are also a number of functions that are toggled between states
(no selections are displayed) using named front-panel keys. These are:
• Display backlight on and off ( On/Off). Press Shift, and then press
the On/Off / Clear key.
• Channel selection (Chan Select). Press Chan Select to switch between
the two input channels.
• Display power measurement (Display Power). Press Display Power to
turn the power-measurement function on and off.
• Frequency offset measurement (FREQ Offset On/Off). Press the Offset
On/Off key in the FREQ area of the front panel to turn the frequency
offset function on or off.
• Power offset measurement (POWER Offset On/Off). Press the Offset
On/Off key in the POWER area of the front panel to turn the power
offset function on or off (the Display Power function must be on).
