HP ESA-L1500A (E4411A) Portable Spectrum Analyzer, 9 kHz to 1.5 GHz

Ideal for field environments, the HP ESA-L1500A gives you fully-sythesized performance in a rugged, 27-pound package for lasting accuracy in tough environments. Rubber-encased frames and the lack of vibration-prone internal adjustments improve reliability during transportation. Rain-resistant front panel, shielded vents, and side-mounted fan protects the instrument in diverse conditions. Continuous background alignment provides accuracy over varying temperatures and eliminates the need for daily calibration. Field measurements can be made accurately and quickly with 5-minute warmup. In addition, the backlit LCD display is readable over a wide variety of lighting conditions, and the flexible tilt handle optimizes viewing angles on the bench or floor for easy installation and service of base stations.

The HP ESA-L1500A gives you a rapid display update rate and state-of-the-art 5-ms sweep time that reduces test time and increases throughput. Also, costly repairs can be avoided with automatic input overload protection, and the use of component integration reduces the probability of failure. The snap on battery pack and 12 vdc operation provide freedom from the AC power main.
