Error messages
Error number: 140
on the marker DC voltage level monitor or the marker DC current level monitor
(MKRMON DCV or MKRMON DCI) and, as a result, the command was ignored. Before
turning on the marker DC voltage level monitor or the marker DC current level monitor,
turn on the corresponding DC bias level monitor (command: BMON VOLT or BMON
CURR).
140 OSC LEVEL MONITOR NOT VALID
When the oscillator level monitor was not on, you attempted to execute a command to turn
on the marker AC voltage level monitor or the marker AC current level monitor
(MKRMON ACV or MKRMON ACI) and, as a result, the command was ignored. Before
turning on the marker AC voltage level monitor or the marker AC current level monitor,
turn on the AC bias level monitor (command: OMON ON).
141 INSUFFICIENT MEMORY
Multiple processes were executed at the same time and the memory was exhausted, which
caused the last process to be aborted. For example, if the execution of an HP Instrument
BASIC program, the printout of the screen, and the transfer of the data array are executed
at the same time, the memory of the system is exhausted, and this message may be
displayed. In this case, terminate some of the processes and then perform the next
operation.
142 WRONG I/O PORT DIRECTION
For a 24-bit input/output (I/O) shared port (port C and port D), you attempted to execute
input/output (I/O) of data in the direction opposite from the preset input/output direction.
The command was invalid. For example, if you use the CIN command to specify port C as
an input port and then use the OUTCIO <value> command to output data from port C, this
error is displayed.
143 FLOATING POINT ERROR OCCURED
Due to the execution of an application inside the instrument for inappropriate data sent
from outside the instrument, an error for floating point operations occurred inside the
instrument. The result of the operation may be incorrect. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
154 INVALID DATE
You attempted to specify the date of the built-in clock using the DATE key or the
SETCDATE command, but the date was out of range and, as a result, the setting you
attempted to execute became invalid. The settable range is: 1900 to 2099 for year, 1 to 12
for month, and 1 to 31 for day. Also, you cannot specify a date that does not exist actually.
Specify correct date data.
193 POWER ON TEST FAILED
In the power-on self-test, a fault of the instrument was detected. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
194 EEPROM WRITE FAIL
A write error was detected in the memory (EEPROM) to store the OPEN, SHORT, and
LOAD data for the four-terminal pair extension setting. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
-100 Command error
A comprehensive syntax error occurred for which the 4294A could not detect further
details of the error. This error code simply indicates the occurrence of a command error
