Carrier Frequency
Carrier frequency: 10 mHz to 15 MHz (100 kHz for triangle
and ramp). The default is 1 kHz.
For arbitrary waveforms, the maximum carrier frequency depends on
the number of points specified in the waveform. The five built-in
arbitrary waveforms can be output at a maximum of 5 MHz.
The carrier frequency must always be greater than or equal to the
peak frequency deviation. If you attempt to set the carrier frequency
to a value less than the deviation, the function generator will auto-
matically adjust the carrier frequency to equal the present deviation.
From the front panel, “
MIN VALUE” is displayed and the carrier
frequency is adjusted. From the remote interface, a -221, “Settings
conflict” error is generated and the carrier frequency is adjusted.
The sum of the carrier frequency and peak frequency deviation must
be less than or equal to the maximum frequency for the selected
function
plus 100 kHz (15.1 MHz for sine and square, 200 kHz for
triangle and ramp, and 5.1 MHz for arbitrary waveforms). If you
attempt to set the carrier frequency to a value that is not valid,
the function generator will automatically adjust the carrier frequency
to equal the present deviation.
From the front panel, “
MAX VALUE” is displayed and the deviation is
adjusted. From the remote interface, a -221, “Settings conflict” error is
generated and the deviation is adjusted.
Front-Panel Operation: Press the Freq key to select any valid
frequency for the selected function (the present amplitude and offset
voltage are used).
