140 OSC LEVEL MONITOR NOT VALID
When the oscillator level monitor is not on, you attempt to execute a command to turn on
the marker's ac voltage level monitor or the marker's ac current level monitor (MKRMON
ACV or MKRMON ACI) and, as a result, the command is ignored. Before turning on the
marker's ac voltage level monitor or the marker's ac current level monitor, turn on the ac
bias level monitor (command: OMON ON).
-220 Parameter error
An error not described by error numbers from -221 to -229 occurs during the analysis of a
program data element. This error occurs, for example, when you attempt to specify an
invalid value for the LOAD correction reference value or the LOAD correction data
(values that are not finite when converted to R-X form impedance values). If this error
occurs, the command is ignored. This error also occurs when you attempt to specify an
invalid LOAD correction reference value from the front panel keys.
-108 Parameter not allowed
The number of parameters is larger than that the command requires. For example, though
the "POIN" command requires one parameter such as "POIN 101," two parameters are
added as "POIN 101,1."
89 PERCENT FORMAT NOT SELECTED
When the percent format is not selected as the display format, you attempt to select delta %
as the data operation setting (you send the MATH DELP command). If you want to select
delta % as the data operation setting, the percent format (command: FMT PERC) must be
selected as the display format.
48 PHASE LOCK LOOP UNLOCKED
Anomalies in the Agilent 4294A's internal circuit are detected (phase lock loop is not
locked). The instrument needs adjustment or repair. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
193 POWER ON TEST FAILED
In the power-on self-test, an instrument fault is detected. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
26 PRINTER: not on, not connected, out of paper
The printer does not respond to commands from the Agilent 4294A. Check the power to
the printer, on-line status, paper, and so on. Otherwise, the connected printer may not be
supported. For information on supported printers, refer to the "Options and accessories"
chapter.
-284 Program currently running
A program is running. This message is displayed when you attempt to perform an
operation that cannot be executed at the same time as a program is running. For example,
this occurs when you attempt to delete a running program.
