When an abnormal condition is detected during op-
eration, the 680XXB displays an error message to in-
dicate that the output is abnormal or that a signal
input or data entry is invalid. It also displays warn-
ing messages to alert the operator to conditions that
could cause an inaccurate signal generator output.
Status messages to remind the operator of current
menu selections or settings are also generated.
Table 6-2 is a summary list of possible error mes-
sages that can be displayed during normal opera-
tions. Table 6-3 is a summary list of possible
warning/status messages.

Error Message
Description
ERROR
Displayed (on the frequency mode title bar) when (1) the
output frequency is not phase-locked or (2) an invalid
frequency parameter entry causes a frequency range
error.
LOCK ERROR
Displayed (in the frequency parameters area) when the
output frequency is not phase-locked. The frequency
accuracy and stability of the RF output is greatly
reduced. Normally caused by an internal component
failure. Run self-test to verify malfunction.
RANGE
Displayed (in the frequency parameters area) when (1)
the
∆
F value entered results in a sweep outside the
range of the instrument, (2) the step size value entered is
greater than the sweep range, or (3) the number of steps
entered results in a step size of less than 1 kHz (0.1 Hz
with Option 11) or 0.1 dB. Entering valid values usually
clears the error.
SLAVE
Displayed (in the frequency parameters area of the
Master 68XXXB) during master-slave operation in VNA
mode when the slave frequency offset value entered
results in a CW frequency or frequency sweep outside
the range of the slave 680XXB. Entering a valid offset
value clears the error.
