Agilent E4403B Specifications and Characteristics
About This Chapter
About This Chapter
This chapter contains specifications and characteristics for the Agilent E4403B 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.
oIf 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.

About This Chapter
oIf Auto Align Off is selected:
—When the analyzer is at a constant temperature, within the operating temperature range, for a minimum of 90 minutes.
—After the analyzer is turned on for a minimum of 90 minutes, the front panel amplitude reference has been connected to the INPUT, and Align Now All has been run.
—When Align Now All is run:
•Every hour
•If the ambient temperature changes more than 3 ° C
•If the 10 MHz reference changes
—When Align Now RF is run (with the front-panel amplitude reference connected to the INPUT):
•Every 24 hours
•If the ambient temperature changes more than 30 ° C
oIf Auto Align All but RF is selected:
—When the analyzer is at a constant temperature, within the operating temperature range, for a minimum of 90 minutes.
—After the analyzer is turned on for a minimum of 90 minutes, the front panel amplitude reference has been connected to the INPUT, and Align Now RF has been run.
—When Align Now RF is run (with the front-panel amplitude reference connected to the INPUT):
•Every hour
•If the ambient temperature changes more than 3 ° C

Immunity Testing |
|
|
Radiated Immunity |
|
Testing was done at 3 V/m |
|
|
according to IEC 801-3/1984. |
|
|
When the analyzer tuned |
|
|
frequency is identical to the |
|
|
immunity test signal |
|
|
frequency, there may be |
|
|
signals of up to − 60 dBm |
|
|
displayed on the screen. |
Electrostatic Discharge |
|
Air discharges of up to 8 kV |
|
|
were applied according to IEC |
|
|
801-2/1991. Discharges to |
|
|
center pins of any of the |
|
|
connectors may cause damage |
|
|
to the associated circuitry. |
