Error Message Descriptions

(16)

Input Overload Decrease max total power in

input.

Excessive input power has been detected which will
cause the ADC to clip the signal. Reduce the signal
level, change the attenuator/max total power setting
(under

Input

 menu), or press

Restart

 if the

RF Input

Range

 is

Auto

.

(17)

Data Acquisition forcing SHORT packing

The data acquisition rate is too high to use longer word
packing.

(18)

Command not implemented

The requested command is not implemented.

(19)

Function not implemented

The requested function is not implemented.

(20)

Signal exceeds maximum allowable power -

Reduce input power

Excessive input power has been detected which will
cause the ADC to clip the signal.

(21)

Memory Allocation FAILURE

(22)

Memory limit caused Data Acquisition to be

truncated

Caused by a Memory Allocation failure. The
measurement limited the acquisition time in order to
complete the measurement.

(23)

Setup INVALID

The parameters chosen create a measurement request
that is impossible to complete, often due to memory
limitations.

(24)

External reference missing

The external frequency reference signal either is
missing, has too low an amplitude, or does not match
the frequency value previously entered into the
instrument memory by the operator.

(25)

Even Second Clock missing

The even second clock signal supplied from the base
station is missing. Check the external trigger input
connection where the even second clock signal is fed
into the instrument.
