Troubleshooting Waveform Files
Symptom Possible Cause
ERROR 224, Text file busy
Attempting to download a waveform that has the same name as the waveform
currently being played by the signal generator.
To solve the problem, either change the name of the waveform being downloaded
or turn off the ARB.
ERROR 628, DAC over range The amplitude of the signal exceeds the DAC input range. The typical causes are
unforeseen overshoot (DAC values within range) or the input values exceed the DAC
range.
To solve the problem, scale or reduce the DAC input values. For more information,
see “DAC Input Values” on page 209.
This error can also occur if an encrypted file (.SECUREWAVE) is being downloaded
to the signal generator from a PC or USB Media with a different suffix (i.e. not
.SECUREWAVE).
To solve the problem, use the Use as or Copy File to Instrument softkey
menus to download the encrypted file to the instrument. For more information, see
“Encrypted I/Q Files and the Securewave Directory” on page 226.
ERROR 629, File format invalid The signal generator requires a minimum of 60 samples to build a waveform and
the same number of I and Q data points.
ERROR –321, Out of memory
There is not enough space in the ARB memory for the waveform file being
downloaded.
To solve the problem, either reduce the file size of the waveform file or delete
unnecessary files from ARB memory. Refer to “” on page 220.
No RF Output The marker RF blanking function may be active. To check for and turn RF blanking
off, refer to “Configuring the Pulse/RF Blank” on page 318. This problem
occurs when the file header contains unspecified settings and a previously played
waveform used the marker RF blanking function.
For more information on the marker functions, see the User’s Guide.
Undesired output signal Check for the following:
— The data was downloaded in little endian order. See “Little Endian
and Big Endian (Byte Order)” on page 207 for more information.
— The waveform contains an odd number of samples. An odd number
of samples can cause waveform discontinuity. See “Waveform
Phase Continuity” on page 217 for more information.
