N9320B RF Spectrum Analyzer
9 kHz to 3.0 GHz
Data Sheet
Definitions and Conditions
The spectrum analyzer will
meet its specifications when:
“Specifications” describe the performance of parameters covered by the
product warranty and apply to the full temperature range of 5 to 45 °C, unless
otherwise noted.
• It is within its calibration
cycle
• It has been turned on at
least 30 minutes
• It has been stored at an
ambient temperature within
the allowed operating range
for at least two hours before
being turned on; if it has
been stored previously at
a temperature range inside
the allowed storage range,
but outside the allowed
operating range
“Typical” values describe additional product performance information that is
not covered by the product warranty. It is performance beyond specifications
that 80 percent of the units exhibit with a 95 percent confidence level over the
temperature range 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 application of the product, but are not covered by the
product warranty.
