Disc Functions
ASCII and Binary File Types
The receiver can save some le types in binary le format, and others in ASCII format. The
format used for each type of data cannot be changed by the user , and are listed in T able 15-2 .
All other types of data are saved as shown in T able 15-2 .
Binary data les require less disc space and the le transfer is faster . If the cal set le is to be
read by a computer , use ASCII format.
T able 15-2 shows the information you can store to internal or external disc drives , and the data
format the receiver uses when saving it (ASCII or binary).

The ASCII data is saved in the CITIle ASCII format. CITIle adds informative headers to the
information in the le , and allows data to be exchanged with the Hewlett-P ackard Microwave
Design System. Complete information on the CITIle format is provided at the end of this
chapter .
Changing between DOS and LIF Discs
When you insert a formatted disc , the receiver can automatically tell whether it is LIF or DOS
format. The only time you must choose between LIF and DOS is when you initialize discs .
Initializing Discs
