FREQUENCY Controls
The FREQUENCY controls allow control of frequency-based
parameters. Exactly which parameter is controlled by the
FREQUENCY controls depends on which panel is displayed, and what
parameters are selected.
For example, in the Main panel, the FREQUENCY controls adjust the
frequency of the generator. In the Sweep panel, the FREQUENCY
controls adjust the start and stop frequencies of the sweep.
The x10 and ÷10 keys will cause the selected frequency parameter to
increase or decrease by a factor of 10.
The INC and DEC keys will increment or decrement the frequency
parameter by a certain step size. The user can program the step size,
choosing either a specific linear step size or choosing ISO, which will
step among the ISO-standard 1/3 octave values. This setting is made
on the Setup panel. Pressing the top right Soft key in this panel will
select between ISO and a specific value. When a specific value is
selected, the frequency controls can be used to adjust the step value.
The FREQUENCY knob can be turned clockwise or counterclockwise
for fine adjustment of the frequency parameter. The knob controls the
frequency with resolution of 0.04%. One full rotation will change the
frequency by about 15%. This may be different for other parameters.
AMPLITUDE Controls
The AMPLITUDE controls allow control of amplitude-based
parameters. Exactly which parameter is controlled by the
AMPLITUDE controls depends on which panel is displayed, and what
parameters are selected.
For example, in the Main panel, the AMPLITUDE controls adjust the
amplitude of the generator. In the Sweep panel, if an amplitude-based
measurement function is selected, the AMPLITUDE controls adjust the
top and bottom amplitude values of the sweep.
The +10 dB and 10 dB keys will cause the selected AMPLITUDE
parameter to increase or decrease by a factor of 10 dB.
