Response to query
(Target to controller)
Spectrum Inversion SPI_ 5 bytes Command or Query.
Used to set or query the Converter spectrum inversion setting,
in the form SPI_x_yyy where:
x = ‘A’ (Converter A) or ‘B’ (Converter B)
yyy = NRM (normal spectrum) or INV (inverted spectrum).
Example: SPI_A_INV (Converter A set to inverted spectrum)
Note: This command is only valid for down converters.
Same as command SPI_x_ SPI_x_
(see Description of
Arguments for details)
Reference Oscillator
Adjust SRO_ 3 bytes,
numeric
Command or Query.
