Flatness correction on: 0.25 dB to 33 MHz, 0.1 dB across center
5 MHz
Phase Flatness (typical with correction on)
0.03 radians pk-pk to 33 MHz
Data Output
A sample data block (equal to the data capture length) can be stored
to the memory internal to the 3030 and then transferred to the con-
troller via the PCI bus. Sample data can be continuously streamed out
of the LVDS connector.
IF data samples have 16 bit resolution. IQ data samples can be 16 or
32 bit resolution.
Data Transfer Rate
Typically 10 Mwords/s (a word is 32 bits long)
