Definitions and requirements
This data sheet contains specifications and supplemental 
information for Agilent N9344C handheld spectrum 
analyzer. The differences between specifications, typical 
performance, and nominal values are described as follows.
Definitions
"Specifications" describe the performance of parameters 
covered by the product warranty and apply to temperatures 
ranging from –10 to 50 °C, unless otherwise noted.
95th percentile values indicate the breadth of the popula-
tion (> 2) of performance tolerances expected to be met in 
95% of the cases with a 95% confidence, for any ambient 
temperature in the range of 20 to 30 °C. In addition to the 
statistical observations of a sample of instruments, these 
values include the effects of the uncertainties of external 
calibration references. These values are not warranted. 
These values are updated occasionally if a significant 
change in the statistically observed behavior of production 
instruments occurs.
"Typical" describes additional product performance 
information that is not covered by the product warranty. It 
is performance beyond specification that 80% of the units 
exhibit with a 95% confidence level over the temperature 
range of 20 to 30 °C. Typical performance does not include 
measurement uncertainty.
"Nominal values" indicate expected performance, or 
describe product performance that is useful in the applica-
tion of the product, but is not covered by the product 
warranty.
Your job just got easier:
• Get the features you need in a field-ready instrument.
• Gain confidence in your measurements with benchtop performance in a handheld instrument.
• Innovative task planner (www.agilent.com/find/taskplanner) reduces test setup time by 95%, 
delivers test automation and consistency, and makes it easy to capture test results, generate 
reports, and share task plans with others.
Conditions required to meet specifications
The following conditions must be met for the analyzer to 
meet its specifications.
• The analyzer is within its calibration cycle. 
• Under auto couple control, except when Swp Time Rule 
is set to Accuracy.
• Any analyzer that has been stored at a temperature 
range inside the allowed storage range but outside the 
allowed operating range must be stored at an ambient 
temperature within the allowed operating range for at 
least two hours before being turned on.
• The analyzer has been turned on at least 30 minutes. 
Certification
Agilent Technologies certifies that this product met its 
published specifications at the time of shipment from the 
factory. Agilent Technologies further certifies that its cali-
bration measurements are traceable to the United States 
National Institute of Standards and Technology (NIST), to 
the extent allowed by the Institute’s calibration facility, and 
to the calibration facilities of other International Standards 
Organization (ISO) members.
