Custom-Cal has a high success rate in repairing the Agilent 8560E, 8561E, 8562E Spectrum Analyzers. We specialize in quick turnaround times and we can handle expedited deliveries upon request.
The HP 8560E, 8561E, 8562E E-series portable spectrum analyzers combine outstanding phase noise, sensitivity, 1 Hz resolution bandwidths, and wide dynamic range in a MIL-rugged package built to withstand harsh environmental conditions. They offer a complete solution for ACP testing of burst carrier signals using digital modulation such as is used in NADC-TDMA, GSM, DECT, CT2-CAI, PDC and PHP system. With digitally implemented resolution bandwidths of 1, 3, 10, 30, and 100 Hz they sweep from 3 to 600 times faster than is possible with comparable analog filters. A narrow 5:1 shape factor allows you to view close-in, low-level signals easily. Digital bandwidths also provide the spectrum analyzer with a full 100 dB onscreen calibrated display.
