Figure 3-9. Ul Error Status Word
The various bits in the error condition word are odes-
cribed as follows:
TRIGGER OVERRUN-Set when the instrument receives
a t-igser while it is still processing a treading from a
previous trigger.
INTERVAL OVERRUN-Set when the instrument cannot
m as fast as the selected interval.
BIG STRING-Set if more than a 10 &mzter message is
sent using the
display (D) command.
UNCAGSet when E'PROM memory fails the self test.
Instrument calibration is invalid.
NO SCANNER-Set if a scanner command is sent with
no scanner installed.
CHAN 4 MAX-Set if attempting to pro&am channels 5
through 8 in the 4pole mode.
CHAN 8 MAX-Set if scanner commands N9 or N19 are
sent.
CAL LOCKED-Set-when trying to calibrate the instru-
ment with the calibration switch in the disable position.
CONFLICT-Set when trying to calibrate the instrument
while it is in an improper state. (i.e. dB function).
Translator Error (TRANSERR)-Set when any one of ten
possible Translator errors occur. Table 3-15 in paragraph
3.10 liits and describes the Translator errors.
NO REMOTE-Set when a progamming command is
received when REN is false.
IDDC-Set when an illegal device-dependent command
(IDDC), such as ELX is received ("E" is illegal).
IDDCO-Set when an illegal device-dependent command
option (IDDCO) such as l9X is received ("9" is illegal).
