Model 3390 Arbitrary Waveform Generator User’s Manual Appendix B: Error Messages
-440 Query UNTERMINATED after
indefinite response
The *IDN? command must be the last query
command within a series of commands in a
command string.
Table B-5:
Instrument errors
Error code Description
501 Cross-isolation UART framing
error
Internal hardware failure.
502 Cross-isolation UART overrun
error
580 Reference phase-locked loop is
unlocked
The PHAS:UNL:ERR:STAT has been turned on
and the internal phase-locked loop is currently
unlocked.
Table B-6:
Self-test errors
Error code Description
621 Self-test failed; square-wave
threshold DAC
A possible malfunctioning digital-to-analog converter
(DAC), failed DAC multiplexer channels, or
associated circuitry.
623 Self-test failed; dc offset DAC
A possible malfunctioning DAC, failed DAC
multiplexer channels, or associated circuitry.
624 Self-test failed; null DAC
625 Self-test failed; amplitude DAC
626 Self-test failed; waveform
filter path select relay
The specified relay is not properly switched or the
attenuator/amplifier does not provide the expected
attenuation or gain. These self-tests use the internal
analog-to-digital converter (ADC) to verify whether
the output path relays, output amplifier (+20 dB), and
output attenuators operate properly.
627 Self-test failed; -10 dB
attenuator path
628 Self-test failed; -20 dB
attenuator path
629 Self-test failed; +20 dB
amplifier path
630 Self-test failed; internal ADC
over-range; condition
A probable ADC failure.
631 Self-test failed; internal ADC
measurement error
A probable ADC failure.
632 Self-test failed; square/pulse
DAC test failure
A probable failure of the square/pulse DAC.
Table B-7:
Arbitrary waveform errors
Error code Description
770 Nonvolatile arb waveform memory
corruption detected
A checksum error was found in the nonvolatile
memory (used to store arbitrary waveforms). The
arbitrary waveform cannot be retrieved.
781 Not enough memory to store new
arb waveform; use DATA:DELETE
All nonvolatile memory locations are occupied. There
is no room to store a new waveform.
