264 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
Standard -223 “Too much data”
Description:
A function returns more data or th e user requests more data than the
application is able to handle.
Example:
A tunable laser source produces m ore data when lambda va lues of a
sweep are stored than the 816x instrument is able to handle. Use the new
SENSE:FUNC:RES:BLOCK? command to split the data aquisition into
multiple parts.
Standard -224 “Illegal parameter value”
[Used where exact value, from a list of possibles, was expected.]
New -225 "Out of memory"
Description:
The request application or function cannot be executed because the in-
strument runs out of memory.
Old -231 "Data questionable (StatValNYetAcc)"
Description:
The data that is retured is not accurate or reliable. The user should repeat
the operation. The reason fo r this error is unspecif ic.
Example:
A powermeter configured a long average time has not completed its cur-
rent measurement cy cle when the u ser queries t he current powe r.
Old -231 "Data questionable (StatRangeTooLow)"
Description:
As -231 (StatValNYetAcc) but for a more spe cific reason: The powe rmeter
readout data is not reliable bec ause the currently set (manual) range does
not correspond with the input power.
Old -261 "Math error in expression (StatUnitCalculation Error)"
Description:
This may occur when the user attempts to transform data in a way that is
currently not possible.
Example:
When a powermeter is measuring very small p owe values in dBm (such as
noise power), negative power values in Watt may also be present (such as
when the powermeter calibration wavelength does not correspond to the
wavelength of input signal). T he instrument cannot t ransform negative
Watt values to dBm because the logari thm of a negative value is not de-
fined.
