-221 Settings conflict;
triggered burst not available for noise
You cannot use the noise function in the triggered burst mode. Noise is
allowed only in the gated burst mode.
-221 Settings conflict;
amplitude units changed to Vpp due to high-Z load
The output units (VOLT:UNIT command) cannot be set to dBm if the
output termination is currently set to “high impedance” (OUTP:LOAD
command). The function generator has converted the units to Vpp.
-221 Settings conflict;
trigger output disabled by trigger external
When the external trigger source is selected ( TRIG:SOUR EXT command ),
the function generator automatically disables the “trigger out” signal.
The rear-panel Trig connector cannot be used for both operations at the
same time.
-221 Settings conflict;
trigger output connector used by FSK
If you have enabled FSK and have selected the external source
(FSK:SOUR EXT command), the “trigger out” signal cannot be enabled
(OUTP:TRIG ON command). The rear-panel Trig connector cannot be
used for both operations at the same time.
-221 Settings conflict;
trigger output connector used by burst gate
If you have selected the gated burst mode (BURS:MODE GAT command)
with burst enabled, the “trigger out” signal cannot be enabled
(OUTP:TRIG ON command). The rear-panel Trig connector cannot be
used for both operations at the same time.
