Specifications

Specifications describe the instrument's warranted performance over the temperature range of 0°C to +55°C unless otherwise
noted. Typical values for the specified parameters represent probable but non-warranted performance. Nominal values provide
useful but non-warranted information about functional performance.

Test Receiver

The following system specifications apply when the 85685A RF preselector (RFP) operates with the 8566B or 8568B spectrum
analyzer (SA) and with or without the 85650A quasi-peak adapter (QPA). The test receiver system is fully GPIB programmable.
Refer to the specific instrument data sheets for more detailed information.
