Instrument Messages Introduction
Instrument Messages Introduction
The analyzer can generate various messages that appear on the display
during operation. There are four types of messages.
• Status Messages, beginning on page 58, appear on the right side of
the analyzer display and/or set status bits in the SCPI Status
Register system. These messages indicate a condition that may
result in erroneous data being displayed. Most messages will only be
displayed until the error condition is corrected. Multiple messages
can be displayed and will be listed in the display area. In each case
the name of the corresponding status bit is indicated in parenthesis.
It will be noted if only a status bit is used (no message).
• Informational Messages, beginning on page 64, provide information
that requires intervention. These messages appear in the status line
at the bottom of the display. If you have a color display and are using
the default display colors, the message will appear in green. The
message will remain until you preset the analyzer, press ESC , or
another message is displayed in the status line. The information
provided in brackets, for example <filename> or <directory>, is a
variable that represents a specific input provided previously.
• Annunciator Bar Messages, beginning on page 70, provide Status
Message information and appear on the left or right side of the
annunciator bar of the analyzer display when running
measurements. Some of the messages appear on the left side of the
annunciator bar in red and other appear on the right side of the
annunciator bar in green. An annunciator bar message may map to
several different status messages, and you should check the related
status messages to determine the cause of your annunciator
message. For more information on status messages, refer to Status
Messages above.
• User Error Messages, beginning on page 20, appear when an
attempt has been made to set a parameter incorrectly or an
operation has failed (such as saving a file). These messages are often
generated during remote operation when an invalid programming
command has been entered. These messages appear in the status
line at the bottom of the display. If you have a color display and are
using the default display colors, the message will appear in yellow.
The message will remain until you preset the analyzer, press ESC, or
another message is displayed in the status line. A summary of the
last 30 error messages preceded by an error number may be viewed
in the Error Queue by pressing, System then Show Errors. Refer to
Table 1-1 for more information on the characteristics of the Error
Queue. When a remote interface initiates activity that generates an
error, the messages are output to the remote bus. When output to the
remote interface, they are preceded by an error number.

Instrument Messages Introduction
When a user error condition occurs in the analyzer as a result of
SCPI (remote interface) activity, it is reported to both the front panel
display error queue and the SCPI error queue. If it is a result of front
panel activity, it reports to the front panel display error queue, and
depending on the error, may also report to the SCPI error queue.
These two queues are viewed and managed separately.

• Pop-up Messages indicate a condition that may require intervention.
They appear in the middle of the display in a framed box. The
message will remain until the appropriate intervention has taken
place or the condition has been corrected.
Error Message Format
The system–defined error numbers are chosen on an enumerated
(“1 of N”) basis. The error messages are listed in numerical order
according to the error message number. Status and Informational
messages without numbers will be listed in alphabetical order following
the numerical listing.
NOTE
To see an error number, view the error queue as described on page 17.
In this chapter, an explanation is included with each error to further
clarify its meaning. The last error described in each class (for example,
–400, –300, –200, –100) is a “generic” error. There are also references to
the IEEE Standard 488.2-1992, IEEE Standard Codes, Formats,
Protocols and Common Commands for Use with ANSI/ IEEE Std
488.1-1987. New York, NY, 1992.

Error Message Example
Error Message Types
Events do not generate more than one type of error. For example, an
event that generates a query error will not generate a device-specific,
execution, or command error.
–499 to –400:
Query Errors
These errors indicate that the analyzer output queue control has
detected a problem with the message exchange protocol described in
IEEE 488.2, Chapter 6. Errors in this class set the query error bit (bit 2)
in the event status register (IEEE 488.2, section 11.5.1). These errors
correspond to message exchange protocol errors described in IEEE
488.2, 6.5. In this case:
• Either an attempt is being made to read data from the output queue
when no output is either present or pending, or
• data in the output queue has been lost.
–399 to –300:
Device-Specific
Errors
An error number in the range –399 to –300 indicates that the analyzer
has detected an error where some device operations did not properly
complete, possibly due to an abnormal hardware or firmware condition.
This is not a error in response to a SCPI query or command, or
command execution. The occurrence of any error in this class will cause
the device-specific error bit (bit 3) in the event status register to be set.
–299 to –200:
These errors indicate that an error has been detected during analyzer
Execution Errors execution.
18
Chapter 1
Instrument Messages
Instrument Messages Introduction
–199 to –100:
These errors indicate that the analyzer parser detected an IEEE 488.2
Command Errors syntax error. Errors in this class set the command error bit (bit 5) in the
event status register (IEEE 488.2, section 11.5.1). In this case:
• Either an IEEE 488.2 syntax error has been detected by the parser
(a control-to-device message was received that is in violation of the
IEEE 488.2 standard. Possible violations include a data element
which violates device listening formats or whose type is
unacceptable to the device.), or
• an unrecognized header was received. These include incorrect
device-specific headers and incorrect or unimplemented IEEE 488.2
common commands.
201 to 799:
Device-Specific
Errors
These errors indicate that a device operation did not properly complete,
possibly due to an abnormal hardware or firmware condition. These
codes are also used for self-test response errors. Errors in this class set
the device-specific error bit (bit 3) in the event status register (IEEE
488.2, section 11.5.1).
The <error_message> string for a positive error is not part of the SCPI
standard. A positive error indicates that the analyzer detected an error
within the GPIB system, within the analyzer firmware or hardware,
during the transfer of block data, or during calibration.
Greater than
10000:
Measurement
Applications
Errors
These errors indicate that an error has been detected while executing
measurements requiring a personality option such as Option BAH, the
GSM Measurement Personality or those measurements found under
the MEASURE front-panel key in Spectrum Analyzer mode.

Query UNTERMINATED after indefinite response
Indicates that a query was received in the same
program message after a query requesting an indefinite
response was executed (see IEEE 488.2, 6.3.7.5).
–430
Query DEADLOCKED
Indicates that a condition causing a DEADLOCKED
query error occurred (see IEEE 488.2, 6.3.1.7). For
example, both the input buffer and the output buffer
are full and the analyzer cannot continue. The analyzer
automatically discards output to correct the deadlock.
–420
Query UNTERMINATED
Indicates that a condition causing an
UNTERMINATED query error occurred (see IEEE
488.2, 6.3.2.2). For example, the device was addressed
to talk and an incomplete program message was
received.
–410
Query INTERRUPTED
Indicates that a condition causing an INTERRUPTED
query error occurred (see IEEE 488.2, 6.3.2.7). For
example, a query was followed by DAB or GET before a
response was completely sent.

Emission bandwidth not found. Consider

This error is normally generated when attempting

you entered (Meas Setup, X dB ) to calculate the emission
bandwidth is the difference between the highest point
on the trace and the point “X dB” down on either side of
the maximum. If the actual difference is less than the
value entered, the emission bandwidth cannot be
computed. Some responses to this situation are as
follows:
1. Connect a signal to the input. (If there is no signal
present, the difference between the trace minimum
and maximum will generally be less than “X dB”.)
2. Increase the span. (If the signal is wide, the
shoulders of the signal might not be present on the
screen, and again, the difference between the trace
minimum and maximum will be less than “X dB”.)
3. Center the signal. (There must be a point on the
trace that is “X dB” down from the maximum on
both sides of that maximum.)

Carrier Not Present.
A carrier signal/burst is expected at the analyzer input.
This signal cannot be found; however, the measurement
will still run. Check input signal connection.
10420
Valid burst not found.
This error only occurs when RF Amptd is selected for
Burst Sync. It indicates that a valid burst envelope
which meets the specified Burst Search Threshold was
not found within the specified Burst Search Length.
Note that the demodulation measurement will proceed
by attempting to demodulate the signal without Burst
Sync alignment. Possible causes may be:
1. Carrier signal is not actually bursted.
2. Burst Search Threshold and/or Burst Search
Length may need to be adjusted.
10421
Cannot lock to carrier.
This error only occurs when attempting to demodulate
OFFSET QPSK signals. It indicates that the
demodulation algorithm is unable to lock to your signal.
Possible causes may be:
1. There is no carrier signal.
2. Carrier signal is present, but Demod settings do not
match the modulation format of the OFFSET QPSK
signal being measured.
3. OFFSET QPSK signal is too noisy to achieve carrier
lock.

Signal Tracking disabled when measuring
DANL Floor (Removal).
Measuring the DANL Floor with DANL Method set to

What You Will Find in This Chapter
What You Will Find in This Chapter
This chapter describes the functional tests and provides information on
how to perform them.
What Are the Functional Tests?
Functional tests are tests of various instrument parameters that give a
high degree of confidence that the analyzer is operating correctly. They
are recommended as a check of analyzer operation for incoming
inspection or after a repair. Measurement uncertainty analysis is not
available for functional tests, and the analyzer is checked against limits
that are wider than the published specifications. The functional tests
are designed to test an analyzer operating within the temperature
range defined by the analyzer specifications using a minimum set of
test equipment. If a test does not pass, performance tests must be run
to confirm a problem exists.
Functional Test Versus Performance Verification
Performance verification tests check a wide range of analyzer
parameters and provide the highest level of confidence that the
analyzer is operating satisfactorily. They are used to verify that the
analyzer conforms to published specifications. They are time consuming
and require extensive test equipment. The functional tests check a
much smaller range of parameters and a limited number of data points
for each parameter. They require only limited test equipment.

Test Descriptions
Each of the following test descriptions include the test limits (pass/fail
criteria), a description of what the test does or what it measures, a list
of equipment required for the performance of the test, an illustration of
the test setup used, and a step by step test procedure. The tests are
designed to be run on an analyzer operating within the operational
temperature range defined by the analyzer specifications. Only perform
tests after the specified warm-up time.
At the end of each test is a test results worksheet. Copy a worksheet to
record your test results for each procedure you’ll be conducting.

Test Description
The Displayed Average Noise Level is measured within the frequency
range specified. The analyzer input is terminated in either 50 Ω or
75 Ω, depending on analyzer options.
The test tunes the analyzer frequency across the band, uses the marker
to locate the frequency with the highest response, and then reads the
average noise in zero span.

Test Description
The output of the synthesized sweeper is fed through a power splitter to
a power sensor and the analyzer. The synthesized sweeper’s power level
is adjusted at 50 MHz to place the displayed signal at the analyzer
center horizontal graticule line. Measurements are made at various
points depending on the model being tested. The signal source
amplitude is measured with a power meter to eliminate errors due to
source flatness. The power meter is zeroed and calibrated before
starting the measurement.

Test Description
A 50 MHz CW signal is applied to the Input of the analyzer. The
amplitude of the source and the analyzer’s reference level are decreased
in 10 dB steps. The analyzer marker functions are used to measure the
amplitude difference between steps. Reference Level Accuracy is tested
in both Log and Linear Scale Modes. Most of the error is contributed
from the output attenuator inaccuracy in the synthesized sweeper and
not the analyzer.

Test Description
A 50 MHz CW signal is applied from a synthesized sweeper to the input
of the analyzer. The source is adjusted for a response at the reference
level. The synthesized sweeper amplitude is adjusted to achieve a
nominal amplitude below the reference level. The analyzer’s amplitude
marker is compared to the actual source change to determine the scale
fidelity error. Most of the error is the source’s output attenuator
inaccuracy from the synthesized sweeper.

Test Description
To test second harmonic distortion, a 50 MHz low pass filter is used to
filter the source output, ensuring that harmonics read by the analyzer
are internally generated and not coming from the source. The source
power and input attenuation on the analyzer are adjusted so –20 dBm
is the power level at the first mixer.

Test Description
A calibrated power sensor is connected to the tracking generator output
to measure the power level at 50 MHz. The power meter is set for REL
mode so that future power level readings are in dB relative to the power
level at 50 MHz. The tracking generator is then stepped to several
frequencies throughout its range. The output power difference relative
to the power level at 50 MHz is measured at each frequency and
recorded. Analyzers with 75 Ω tracking generators are only tested from
1 MHz to 1500 MHz.
