Reference > Troubleshooting Error and Information Messages
This message appears if the "Results Length", the time over which the measurement computed its results,
is less than the Actual Analysis Length reported in the Analysis Time control panel tab and the Time
Overview display. The Results Length is indicated by the magenta line below the Time Overview graph.
This can occur because the acquisition contained more data samples than a measurement can process (for
example, digital demodulation is limited to 80,000 samples) or the measurement had to use some of the
fi rst and last samples for pre-measurement processes.
Analysis length too small for current setup
Increase the Analysis Length or decrease the RBW (Spectrum, ACPR, MCPR).
Avg Tx not available in Volts units
The Average Transmitted Power measurement is not de fi ned for Volts.
Cache fi le missing. Unable to create new cache fi le. Not enough free space (need XXX GB).
Remove unnecessary fi les, defragment the hard drive using a standard disk management utility,
then relaunch application.
The instrument is unable to create a required cache fi le. To resolve this issue, use a standard disk
management utility to defragment the hard disk. If this error persists, backup your data (including any
setup
fi les you have saved), any applications and associated fi les you have installed and perform an OS
restore on the hard disk. After restoring the OS, reinstall the RSA6100A Series product software.
NOTE.
The speci fi c OS restore procedure required for your instrument depends on when your instrument
was manufactured. Go to www.tektronix.com/manuals and download the RSA6100A Series Service
Manual, Tektronix part number 077-0249-00 or later. Review the OS restore procedure in the manual to
determine the procedure appropriate to your instrument.
Can’t get acquisition data record
No acquisition record currently exists in memory (run an acquisition or recall a fi le), or an error has
occurred. Repeat the acquisition.
Can’t replay data from swept acq
The measurement could not produce results because it is a real-time only measurement but was asked to
reanalyze (Replay) an acquisition taken in swept mode.
Can’t replay. Live data needed for swept settings
The measurement could not produce results because it was asked to reanalyze (Replay) the acquisition but
it is in Swept acquisition mode. Swept-mode measurements cannot analyze recalled data.
CISPR accuracy limited by acq memory. Adjust RBW or freq range
The CISPR function was applied, but the available data did not represent a long enough time to satisfy
CISPR requirements. Increasing RBW reduces the amount of time needed for analysis. Reducing
frequency range (for example, by reducing Span), decreases sample rate, allowing the available memory
to cover a longer time period.
