Output Configuration
This section contains information to help you configure the function
generator for outputting waveforms. You may never have to change
some of the parameters discussed here, but they are provided to give
you the flexibility you might need.
Output Function
The function generator can output five standard waveforms including
sine, square, triangle, ramp, and noise. You can also select one of five
predefined arbitrary waveforms or download your own custom waveforms.
You can internally modulate any of the standard waveforms (including
arbitrary) using
AM
,
FM
,
FSK
, or burst modulation. Linear or logarithmic
frequency sweeping is available for any of the standard waveforms
(except noise) and arbitrary waveforms.
The default function is sine wave.
•
Possible Conflict with Output Frequency
: The output frequency is
automatically adjusted if you select a function whose maximum
frequency is
less than
that of the currently active function.
For example, if you output a 1 MHz sine wave and then change the
function to triangle wave, the function generator will adjust the
output to 100 kHz (the upper limit for triangle waves).
From the front panel, “
FREQ LIMIT
” is displayed and the frequency is
adjusted. From the remote interface, a
-221, “Settings conflict”
error
is generated and the frequency is adjusted.
•
Possible Conflict with Output Amplitude
: The output amplitude is
automatically adjusted if you select a function whose maximum
amplitude is
less than
that of the currently active function. This
conflict may arise when the output units are
Vrms
or
dBm
due to the
differences in crest factor for the output functions. For example, if you
output a 5 Vrms square wave (into 50 ohms) and then change the
function to sine wave, the function generator will adjust the output
amplitude to 3.535 Vrms (the upper limit for sine waves in Vrms).
From the front panel, “
AMPL LIMIT
” is displayed and the amplitude
is adjusted. From the remote interface, a
-221, “Settings conflict”
error is generated and the amplitude is adjusted.
