Error Messages
Error Messages in Alphabetical Order
ASCII: MISSING 'BEGIN' STATEMENT. Error Number 193. The CITIfile you just downloaded over the GPIB or
via disk was not properly organized. The analyzer is unable to read the “BEGIN” statement.
ASCII: MISSING 'CITIFILE' STATEMENT. Error Number 194. The CITIfile you just downloaded over the GPIB or
via disk was not properly organized. The analyzer is unable to read the “CITIFILE” statement.
ASCII: MISSING 'DATA' STATEMENT. Error Number 195. The CITIfile you just downloaded over the GPIB or
via disk was not properly organized. The analyzer is unable to read the “DATA” statement.
ASCII: MISSING 'VAR' STATEMENT. Error Number 196. The CITIfile you just downloaded over the GPIB or via
disk was not properly organized. The analyzer is unable to read the “VAR” statement.
AUTOBIAS IS TURNED OFF. Information Message. The modulator bias mode is switched off , either manually
or due to insufficient signal for bias adjust. Autobiasing can be switched on in the Service Menu and it is
advised to switch autobias ON when making O/O and O/E measurements.
AVERAGING INVALID ON NON-RATIO MEASURE. Error Number 13. You cannot use sweep-to-sweep averaging
in single-input measurements. Sweep-to-sweep averaging is valid only for ratioed measurements (A/R, B/R,
A/B, and S-parameters). You can use other noise reduction techniques, such as narrower IF bandwidth, for
single input measurements.
BAD FREQ FOR HARMONIC. Error Number 181. You recalled a calibration that resulted in start and stop
frequencies that are beyond the allowable limits.
BANDWIDTH LIMIT INVALID: MIN BW > MAX BW. Information Message. The bandwidth test has a minimum
bandwidth greater than the maximum bandwidth. Change the minimum bandwidth to a frequency less
than the frequency of the maximum bandwidth or change the maximum bandwidth to a frequency greater
than the frequency of the minimum bandwidth
BATTERY FAILED. STATE MEMORY CLEARED. Error Number 183. The battery protection of the non-volatile
CMOS memory has failed. The CMOS memory has been cleared. Refer to Chapter 8, “Preset State and
Memory Allocation” for more information about the CMOS memory.
BATTERY LOW! STORE SAVE REGS TO DISK. Error Number 184. The battery protection of the non-volatile
CMOS memory is in danger of failing. If this occurs, all of the instrument state registers stored in CMOS
memory will be lost. Save these states to a disk. Refer to Chapter 8, “Preset State and Memory Allocation”
for more information about the CMOS memory.
BLOCK INPUT ERROR. Error Number 34. The analyzer did not receive a complete data transmission. This is
usually caused by an interruption of the bus transaction. Clear by pressing the Local, key or aborting the
I/O process at the controller.
BLOCK INPUT LENGTH ERROR. Error Number 35. The length of the header received by the analyzer did not
agree with the size of the internal array block. Refer to the programmer’s guide for instructions on using
analyzer input commands.
CALIBRATION ABORTED. Error Number 74. You have changed the active channel during a calibration, so the
calibration in progress was terminated. Make sure the appropriate channel is active and restart the
calibration.
CALIBRATION REQUIRED. Error Number 63. A calibration set could not be found that matched the current
stimulus state or measurement parameter. You will have to perform a new calibration.
