OPTION 008 RF PROFILES AND COMPLEX SWEEP
Annex-C-21
RF profiles
Used for specifying a level profile over a frequency range. Consists of relative offsets,
from a predefined reference level, at user defined frequencies. Linear interpolation is used to
calculate the level between frequency points. Up to 10 profiles can be stored away in non-volatile
memory for future use.
These profiles can be used in conjunction with segmented sweeps as well as in NORMAL
instrument mode, but not with ordinary frequency carrier sweeps.
The following GPIB commands are used to provide GPIB control of the RF profiles.
PROFILE [not used alone]
:STATUS [not used alone]
:NUM Select Profile (0-9)
Data type: Decimal Numeric Program Data
Allowed Suffices: None
Default Suffix: None
:ENABLE Enable Selected Profile
:DISABLE Disable Selected Profile
:SAVE Store profile setting and status in memory
Data type: None
Allowed Suffices: None
Default Suffix: None
PROFILE:STATUS?
Responds with Selected Profile number (0-9) and Status as
follows:
:PROFILE:STATUS:NUM <nr1>;<status>
Example: :PROFILE:STATUS:NUM 4;ENABLE
To edit a profile, first set the instrument mode to PROFILE
IMODE Select instrument mode
Data type: Character program data (NORMAL, SWEEPER or PROFILE)
Allowed Suffices: None
Default Suffix: None
Example: IMODE PROFILE
PROFILE [not used alone]
:EDIT [not used alone]
:CFRQ Set Carrier Frequency
Data type: Decimal Numeric Program Data
Allowed Suffices: GHZ, MHZ, KHZ, HZ
Default Suffix: HZ
