Error Messages in Numerical Order
133 CAN'T CHANGE ON LIST SWEEP
When list sweep is selected, the following parameters are not allowed to be changed:
CENTER, SPAN, START, STOP
NOP
IFBW or RBW
POWER
DC SOURCE
Modify the list table to change these parameters in the list sweep.
134 CAN'T COUPLE IN CURRENT INPUTS
When one channel measures a ratio measurement, and the other one measures an absolute
measurement (for example: A/R and B),
N
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
COUPLED CH can not be turned on.
135 COUPLED CHAN - BETWEEN NA&NA OR ZA&ZA
The analyzer types of both channels must be the network analyzer mode or impedance
analyzer mode when the coupled channel is turned on. It is not possible to turn the coupled
channel on in spectrum analyzer mode
.
136 DC SOURCE OVERLOAD
The DC SOURCE output is overloded.
137 DC CURRENT LIMIT OCCURED
The output current at DC SOURCE port is reached to an upper limit and the output voltage is
reduced so that the current does not exceed the upper limit. This message appears when the
DC SOURCE port is used in voltage control mode
.
138 DC VOLTAGE LIMIT OCCURED
The output voltage at DC SOURCE port is reached to an upper limit and the output current is
reduced so that the voltage does not exceed the upper limit. This message appears when the
DC SOURCE port is used in current control mode.
141 INSUFFICIENT MEMORY
If a lot of tasks is executed at same time, memory might be insucient for a while.(For
example, running HP Instrument BASIC program, printing a screen, and sending or receiving
data array by HP-IB are required at same time
.) Please wait until nishing some tasks then
execute the next task.
143 FLOATING POINT ERROR OCCURED
Indicate that a oating point error occured in the analyzer. Data processing may not be correct.
This error message is used when an internal application was executed for illegal data sent from
an external device, or when an internal software bug was detected. Contact your nearest
Hewlett-Packard oce.
146 ON POINT NOT ALLOWD FOR THE CURRENT TRIG
The trigger event mode cannot be changed to the ON POINT mode because the current trigger
source setting does not allow the ON POINT mode
. The ON POINT mode is available for only
MANUAL, EXTERNAL, and BUS trigger sources of the network analyzer mode
.
