Memory Cards
Memory Card Storage Space
Procedures use 12-16 records each. A Library uses 20-35 records. A single library
must be included on the card. A record is 256 bytes. Approximately 11 kilobytes
of overhead is required on each card.
Use the following formula to estimate the storage space needed:
Storage Space(in kilobytes) = (Number of Procedures × 4.1) + 20
For example, if you want to save ten different procedures, you will need 61
kilobytes of memory. The 64 kilobyte or 128 kilobyte card is sufficient.
The storage space you need for data collection depends on the number of test
results that are saved. You will need approximately 4 kilobytes per page of test
results that you save. A page of test results is about 57 lines of CRT or printer
output.
The storage space of smaller SRAM cards can be quickly used. If you are
collecting large quantities of data, data collection using a PC or printer may be
preferable.
Initializing a Memory Card
Initializing HP 11807A cards (Smart Cards) using the TESTS Save/Delete
Procedure
screen automatically defaults to LIF format. Initializing HP 11807E
cards (PCMCIA) using the TESTS
Save/Delete Procedure screen
automatically defaults to DOS format. However, initializing cards from the
Save/Delete Procedure screen is only available on HP 8920B or HP
8920A,D test sets with firmware above revision A.14.00. If these settings do not
match your needs, or you have firmware below revision A.14.00, there is another
method described below in which you may select the format.
• Press TESTS.
• Select Save/Delete Procedure from the CUSTOMIZE TEST PROCEDURE
list.
• Insert the SRAM card in the slot on the front panel. (Make sure the switch on the card
is not in the write-protected position).
•Press k3 (Init Card).
• Press Yes if you want to continue.
