version of GPIB. Requires USB/Memory board assembly. USB/Memory
board contains both USB and extended memory circuitry although a
license keyword is required for each option.
Option 115 (All PSA Series) Extended Memory. Provides 512 MB of
additional memory for optional measurement personality or user files
such as state or trace files. Requires USB/Memory board assembly.
USB/Memory board contains both USB and extended memory circuitry
although a license keyword is required for each option. See Option 117
Secure Memory description for additional information.
Option 117 (All PSA Series) Secure Memory Erase. Forces all user
files such as trace, state and screen data to be stored only on the
extended memory board. Prohibits the storage of instrument
measurement personalities or any other non-user data.
Two levels of security are provided. Provides a means to thoroughly
erase only user data by erasing the contents of the extended memory
board. This level of security allows the core analyzer and measurement
personalities to remain intact so the analyzer will still function.
The second level is an erase all routine that clears all instrument
memory including memory on the CPU assembly resulting in a
non-functional instrument.
See "Managing Security" under the Systems section of the PSA User's
Guide (Volume 1) and the firmware upgrade chapter in this manual for
important information.
Requires USB/Memory board assembly and license keyword for Option
117. Option 115 is incompatible with Option 117 since Option 115 also
provides storage of measurement personalities to the extended memory
board.
Option 122 (E4440A, E4443A, E4445A, E4446A, E4448A)
80 MHz Bandwidth Digitizer. Provides 80 MHz wideband IF from
10 MHz to the upper frequency range of the analyzer. This option adds
the A31 Wideband Analog IF and A32 Wideband Digital IF assemblies
and associated filtering and cabling.
Option 123 (All PSA Series) Switchable Microwave and Millimeter
Wave Preselector Bypass. Provides a switchable signal path that
bypasses both the microwave 3 to 26.5 GHz preselector in RHYTHM,
and the 26.5 to 50 GHz preselector in the SBTX. The option adds a
microwave mixer and switches. If this option is installed, Option AYZ
external mixing cannot be installed due to limited LO ports.
