Error messages
Order of Alphabet
error coefficients based on the measurement.
-281 Cannot create program
Programs cannot be created. Insufficient memory is suspected.
35 CAN'T CALCULATE EQUIVALENT PARAMETERS
Because measurement data does not match with the selected equivalent circuit, equivalent
circuit parameters cannot be calculated. Acquire data again or select another equivalent
circuit.
82 CAN'T CHANGE -ANOTHER CONTROLLER ON BUS
When an active controller was on the same GPIB bus, you attempted to set the 4294A as a
system controller. Unless another active controller is removed from the same GPIB bus,
you cannot set the 4294A as a system controller.
133 CAN'T CHANGE ON LIST SWEEP
When the sweep type was set to the list sweep, you attempted to execute a command to
specify the lower limit of a partial search range (SEARMIN) or a command to specify the
upper limit of a partial search range (SEARMAX) and, as a result, the command was
ignored. When the sweep type is the list sweep, you cannot specify a partial search range
using the lower limit and the upper limit. Before specifying a partial search range using the
lower limit and the upper limit, specify a sweep type other than the list sweep (command:
SWPT LIN or SWPT LOG).
130 CAN'T CHANGE ON ZERO SPAN
During the execution of the list sweep when the sweep span of each segment was zero, you
attempted to change the list sweep span (integrated total span of individual segments
specified as the horizontal axis of the graph for the list sweep) to the single span (the way
to specify a linear frequency axis for the horizontal axis of the graph whose left edge and
right edge are the minimum frequency and the maximum frequency within all segments)
using the LIST SPAN [ ] key or the LISPAN SINGLE command and, as a result, the
command was ignored. When executing the list sweep while the sweep span of each
segment being zero, the list sweep span is automatically set to the segment span and cannot
be changed.
114 CAN'T SAVE GRAPHICS WHEN COPY IN PROGRESS
You commanded to save the graphics screen during the execution of copying (outputting to
a printer), but the graphics screen cannot be saved during output to a printer.
-140 Character data error
An error not included in error numbers between -141 and -149 occurred during the syntax
analysis of a character data element.
-148 Character data not allowed
A character data element (that did not violate the standard) was received at where the
4294A did not accept any character data elements. For example, a parameter must be
enclosed with double quotation marks (“) but they are missing.
-144 Character data too long
The length of the character data element exceeds 12 characters. (Refer to
IEEE488.2,7.7.1.4.)
-100 Command error
