Model 3390 Arbitrary Waveform Generator User’s Manual Appendix B: Error Messages
-148 Character data not allowed
A discrete parameter was received when it was not
expected.
-151 Invalid string data
An invalid character string was received.
-158 String data not allowed
A character string was received when it was not
permitted for this command.
-161 Invalid block data
For a definite-length block, the number of bytes of
data sent does not match the number of bytes
specified in the block header.
-168 Block data not allowed
This command does not accept the data format.

Execution errors
Error code Description
-211 Trigger ignored
A GET or *TRG trigger was received, but the trigger
was ignored.
-221 Settings conflict; turned off
infinite burst to allow immediate
trigger source
An infinite burst count command can only be sent
from a remote interface.
-221 Settings conflict; infinite
burst changed trigger source to BUS
An infinite burst count command can only be sent
from a remote interface.
-221 Settings conflict; burst
period increased to fit entire
burst
The specified number of cycles in the BURS:NCYC
command takes priority over the burst period. The
instrument increased the burst period to
accommodate the burst count or the waveform
frequency.
-221 Settings conflict; burst count
reduced to fit entire burst
The burst period is currently at its maximum. The
waveform generator adjusted the burst count to
accommodate the waveform frequency.
-221 Settings conflict; triggered
burst not available for noise
Noise function is not permitted in the triggered burst
mode.
-221 Settings conflict; amplitude
units changed to Vpp due to high-Z
load
dBm is not available as a unit when the output
termination is set to high impedance.
-221 Settings conflict; trigger
output disabled by trigger external
When accepting an external trigger source, the Trig
Out signal is automatically disabled.
-221 Settings conflict; trigger
output connector used by burst gate
If you have enabled burst and selected gated burst
mode, the Trig Out signal is automatically disabled.
-221 Settings conflict; trigger
output connector used by FSK
If you have enabled FSK and are using the external
trigger source, the Trig Out signal is automatically
disabled.
-221 Settings conflict; trigger
output connector used by trigger
external
When accepting an external trigger source, the Trig
Out signal is automatically disabled.
-221 Settings conflict; frequency
reduced for user function
The maximum output frequency for an arbitrary
waveform is 10 MHz. When you change function
from one allowing higher frequency to arbitrary
waveform, the frequency is adjusted to 10 MHz.
