Data Storage

Files stored: Autotests, tilt, channel plans, scan and forward sweep.

Also reverse sweep and reverse amp alignment on SDA-5000 with

OPT 1 and/or 2. Spectrum mode (regular with max hold and

CSO/CTB). Allocated on demand. The storage capability is simulta-

neous- more of one file type can be "traded" for less of another. All

files stored as database, not as screen picture. Typical mix of files

for 78-channel plan 8 channel plans, 16 sweep references 80

sweep traces; 40 scan files 20 spectrum displays; 20 autotests
