RF Network Analyzers
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
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 analyzer’s programmers 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.
CANNOT READ/WRITE 1 FILE SYSTEM
Error Number
203
The disk is being accessed by the analyzer and is found to contain an 1
(hierarchical file system) or files nested within subdirectories. The analyzer does
not support 1. Replace the disk medium with a LIF or DOS formatted disk that
does not contain files nested within subdirectories.
CAUTION: POWER OUT MAY BE UNLEVELED
Error Number
179
There is either a hardware failure in the source or you have attempted to set the
power level too high. The analyzer allows the output power to be set higher or
lower than the specified available power range. However, these output powers
may be un-leveled or unavailable. Check to see if the power level you set is
within specifications. If it is, refer to Chapter 7 , “Source Troubleshooting.”
CORRECTION CONSTANTS NOT STORED
Error Number
3
A store operation to the EEPROM was not successful. You must change the
position of the jumper on the A7 CPU assembly. Refer to “A7 Switch Positions”
on page 3-4.
CORRECTION TURNED OFF
Error Number
66
Critical parameters in your current instrument state do not match the
parameters for the calibration set, therefore correction has been turned off. The
critical instrument state parameters are sweep type, start frequency, frequency
span, and number of points.
