Agilent E4408B Specifications and
Characteristics
About This Chapter
This chapter contains specifications and characteristics for the Agilent
E4408B spectrum analyzer. The distinction between specifications and
characteristics is described as follows.
• Specifications describe the performance of parameters covered by
the product warranty. (The temperature range is 0 °C to 55 °C,
unless otherwise noted.)
• Characteristics describe product performance that is useful in the
application of the product, but is not covered by the product
warranty.
• Typical performance 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 20 to 30 °C.
Typical performance does not include measurement uncertainty.
• Nominal values indicate the expected performance, or describe
product performance that is useful in the application of the product,
but is not covered by the product warranty.
The following conditions must be met for the analyzer to meet its
specifications.
o The analyzer is within the one year calibration cycle.
o If
Auto Align All is selected:
— After 2 hours of storage within the operating temperature range.
— 5 minutes after the analyzer is turned on with sweep times less
than 4 seconds.
— After the front-panel amplitude reference is connected to the
INPUT, and
Align Now RF has been run, after the analyzer is
turned on. And, once every 24 hours, or if ambient temperature
changes more than 30 °C.
