Function Limitation
If you change to a function where the maximum frequency is
less than the current function, the frequency will be
adjusted to the maximum value for the new function.
For example, if you are currently outputting a 20 MHz sine
wave and then change to the Ramp function, the U2761A
will automatically adjusts the output frequency to 200 kHz
(the upper limit for Ramp).
Amplitude Limitation
If you change to a function where the maximum amplitude
is less than the current function, the amplitude will
automatically be adjusted to the maximum value for the new
function. This may occur when the output units are Vrms or
dBm due to the differences in crest factor for the various
output functions.
For example, if you output a 2.5 Vrms Square wave (into
50 Ω) and then change to the Sine wave function, the
U2761A will automatically be adjusted the output amplitude
to 1.768 Vrms (the upper limit for Sine wave in Vrms).
