Data Sheet

These specifications apply to the Agilent

Technologies E7402A and E7405A EMC
analyzers.

Frequency Specifications Specifications

Frequency range All specifications apply over 0 °C to +55 °C unless other-
E7402A wise noted and are covered by the product warranty. The
dc coupled 100 Hz1 to 3.0 GHz analyzer will meet its specifications when: it’s within the
ac coupled 100 kHz1 to 3.0 GHz one year calibration cycle, AUTO ALIGN [ALL] is selected,
E7405A stored a minimum 2 hours within the operating tempera-
Band LO harmonic = N ture range, turned on for at least 5 minutes, and Align
0 1- dc coupled 30 Hz1 to 3.6 GHz Now RF has been run once every 24 hour period. Typical per-
ac coupled 100 MHz to 3.6 GHz formance describes the level at which 80% of the units will
1 1- 2.85 GHz to 6.7 GHz meet or exceed with a 95% confidence level over 20 to 30 °C,
2 2- 6.2 GHz to 13.2 GHz but is not covered in the product warranty. Characteristics
3 4- 12.8 GHz to 19.2 GHz describe expected product performance levels that are not
4 4- 18.7 GHz to 26.5 GHz covered in the product warranty.
