Memory error

and a floppy disk is write-protected. If necessary, disable the write-protection of the floppy

disk.

-311 Memory error

An error is detected in the memory of the Agilent 4294A.

34 MEMORY TRACE NOT ACTIVE

Although no data is stored in the memory trace, you attempt to execute a command (DISP

MEMO, DMNM, and so on) that uses the memory trace. Therefore, the command is

invalid. First, use the DATMEM command and store data in the memory trace.

-252 Missing media

You attempt to access a storage device, but the media type does not exist or is not installed

correctly. This message is displayed, for example, when you specify the floppy disk drive

as the storage device but no floppy disk is correctly inserted into the drive.

-109 Missing parameter

The number of parameters is less than that the command requires. For example, although

the “POIN” command requires 1 parameter such as “POIN 101,” no parameter is added as

“POIN.”

36 MUST BE MORE THAN 2 POINTS FOR ANALYSIS

Although the calculation of equivalent circuit parameters (CALCULATE PARAMETERS

key, CALC PARMS key, or CALECPARA command) is executed, because the number of

points (NOP) within the sweep range (if the partial search function is on and within the

specified search range) is two, they cannot be calculated. Set the number of points within

the sweep range (if the partial search function is on, within the specified search range) to

three or more.

98 NO ACTIVE MARKER

When the marker is not displayed, you attempt to execute the marker moving (Marker?)

function and, as a result, the command is ignored. For example, when the marker is not

displayed, a command corresponding to the MKR?START key (MKRSTAR) is sent. Before

executing the marker moving function, display the marker (command: MKR ON).

0 (No error)

No error has occurred. This message is not displayed on the LCD. 0 is returned as the error

number if no error occurs in the instrument when the OUTPERRO? command is sent

through GP-IB.

100 NO FIXED DELTA MARKER

When the fixed D marker (FIXED DMKR) is not displayed, you attempt to execute a

command of a function that needs the display of the fixed D marker and, as a result, the

command is ignored. For example, when the fixed D marker is not displayed, a command

corresponding to the FIXED DMKR VALUE, FIXED DMKR AUX VALUEN key

(DMKRVAL <value>, DMRRAUV <value>) is sent. Before executing a function using the

fixed D marker, first display the fixed D marker (command: DMKR FIX).

113 NO STATE/DATA FILES ON DISK

Although you attempt to display the list of files and directories on a floppy disk on the

1 2 ... 442 443 444 445 446 447 448 449 450 451 452 ... 468 469
