The 85620A mass memory module is a plug-in module for the 8560A, 8560B and 8560E-series portable spectrum analyzers. The 85620A is a standard feature of the Keysight 8560EC-series spectrum analyzers. It adds measurement personality capability, enough memory to store 100 traces, memory-card capability, and computer capability without an external controller. Create complex measurement routines and save then as single-key measurements stored on memory cards or in the module's 128 KB of battery-backed RAM. One Keysight 85700A 32K-byte RAM memory card is supplied with the mass memory module.
