Type. Shows the type of data. In the RSA2200A series, only this type is used:
H
WCA380IQT. The data block contains I and Q values in the time domain.
This type is called WCA380IQT for compatibility with the *.IQT file of the
WCA300 series.
FrameReverse. Shows the frame order. This item is always Off in the
RSA2200A series. The following parameters are provided:
H
Off.
Frames are stored in the order of acquisition. The last frame in the data
block is the latest acquired frame.
H
On.
Frames are stored in the reverse order of acquisition. The first frame in
the data block is the latest acquired frame.
FramePadding. The analyzer adds dummy frames when acquired frames do not
fill BlockSize (block size). Figure 3--120 shows the dummy frames. The
FramePadding parameter is always set to Before in the RSA2200A series.
H
Before. Adds dummy frames before valid frames, but not in the first block.
H
After.
Adds dummy frames after valid frames, but not in the last block.

Band. Shows the frequency band that was set when the analyzer acquired the
data. It is necessary only when the analyzer reloads the data.
MemoryMode. Shows the memory mode that was set when the analyzer
acquired the data. It is necessary only when the analyzer reloads the data.
