Data Processing Commands
:DPRocessing[:MODE]
Command
:DPRocessing[:MODE] {DIRect|DDC}
Description
The command selects the data processing mode for the specified channel.
The selected mode determines, which type of data is forwarded to the
capture memory and the ODI port.
DIRect:
No data processing, the raw ADC samples are forwarded to the
capture memory and the ODI port.
DDC:
Digital-down conversion, the ADC samples are down-converted
from the center frequency to baseband followed by a decimation and then
forwarded to the capture memory and the ODI port.
<N>
An integer, 1-4 in a single digitizer system.
Query
:DPRocessing[:MODE]?
The query returns the current data processing mode for the specified
channel.
Returned Format
:DPRocessing[:MODE]] {DIRect | DDC}<NL>
:DPRocessing:DDC:DECimation
Command
:CHANnel<N>:DPRocessing:DDC: DECimation {POW5 | POW6
| POW7 | POW8}
Description
The command sets the decimation factor of the DDC for the specified
channel. All decimation factors are powers of 2.
