ASCII: MISSING ‘VAR’ STATEMENT
Error Number The 
CITblle
 you just downloaded over the HP-IB or via disk was not properly
196 
organized. The analyzer is unable to read the “VAR” statement.
AVERAGING INVALID ON NON-RATIO MEASURE
Error Number You cannot use sweep-to-sweep averaging in single-input measurements.
13 
Sweep-sweep averaging is valid only for 
ratioed
 measurements (A/R, B/R, 
A/B,
and S-parameters). You can use noise reduction techniques, such as narrower
IF bandwidth, for single input measurements
BAD FREQ FOR HARMONIC OR FREQ OFFSET
Error Number You turned on time domain or recalled a calibration that resulted in start and
181 
stop frequencies that are beyond the allowable limits.
BATTERY FAILED. STATE MEMORY CLEARED
Error Number The battery protection of the non-volatile CMOS memory has failed. The CMOS
183 
memory has been cleared. Refer to the

 STORE SAVE REGS TO DISK
Error Number 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 and refer to the

BLOCK INPUT ERROR
Error Number The analyzer did not receive a complete data transmission. This is usually
34 
caused by an interruption of the bus transaction. Clear by pressing the 
ILocal
key or aborting the I/O process at the controller.
