Making a backup disk
Hewlett-Packard
1
recommends that you make a backup or extra copy of the
disk data, label it properly, and make sure it is only used with the source or
receiver that its data describes.
If you need to make a backup copy of a LIF-formatted disk, you must have an
HP controller (computer). This includes all 200 and 300-series HP 9000 con-
trollers such as, HP 9836, 9826, 310, 320, etc. In addition, the disk drive must
be an HP CS80 disk drive, such as an HP 9122C/D dual-sided model.
Refer to the computer’s User’s Guide for instructions on how to make back-up
copies or copy files.
How labeled coefficients are used
The labeled coefficient data consists of nine coefficients that are used in a
polynomial curve to describe the magnitude and phase modulation response
of the source or receiver. The curve terms (A through I) are derived from the
same data points that are on the disk.
A typical label, as shown in Figure 2-3 on page 2-9 , has a
CAL DATA #
which
describes the data.
