F
-256 File name not found
A designated file could not be found and the command has not been correctly executed.
For example, attempts have been made to read and write on a file that does not exist or a
disk has not been properly inserted.
95 Frequency sweep only
A command that is only valid when the sweep parameter is in frequency has been sent. For
example, when a sweep parameter other than frequency is set, the
CALC{1-5}:MARK:UNIT command is attempted in order to set the marker X-axis display
to relaxation time (1/2f).
First, use the SWE:TYPE command to set the sweep parameter to frequency.
G
-105 GET not allowed
While receiving a program message, the Group Execution Trigger (GET command in
HTBasic) has been inputted (refer to IEEE4888.2,7.7). For example, a wait command such
as "*OPC?", or "*WAI" has been sent.
I
-224 Illegal parameter value
The parameter value is not appropriate. For example, when the program message
"DISP:TRAC1:Y:SPAC OBAS" has been sent instead of the correct program message
"DISP:TRAC1:Y:SPAC LOG", the parameter rate is regarded by the E4991A as
inappropriate.
Refer to the command reference and confirm that the parameter value is correctly inputted.
71 Impedance measurement mode only
A command has been sent that is only valid for Impedance Measurement Mode. For
example, during the Magnetic Material Measurement Mode, the
SENS:CORR2:CKIT:STAN1:C command has been attempted in order to define the user
defined fixture compensation kit.
Select Impedance Measurement Mode.
-213 Init ignored
Because another measurement is already underway, the Measurement Initialize Request
("INIT" command) has been ignored. For example, this happens when changing the setting
of "INIT:CONT" to "OFF" and the "TRIG:SOUR" command to "BUS" or when
attempting a trigger with the "*TRG" command. If the "INIT" command is sent to the
E4991A before the sweep is completed (without a wait time), it is regarded as an invalid
command.
-161 Invalid block data
Even though the block data is expected, the received block data is invalid for some reason
(refer to IEEE488.2, 7.7.6.2). For example, before the length of block data has been filled,
an END message is received.
