SRAM Memory Cards 
A Static Random Access Memory (SRAM) Card can be used to store test results 
and procedures you make. The following parts can be used. 
SRAM memory cards use a lithium battery (For 11807A: part number CR 2016 or 
HP part number 1420-0383. For 11807E: part number CR 2025 or HP part 
number 1420-0509). Programs and data will be retained for over one year if the 
memory card is stored at 25
° C. The memory card is powered by the test set while 
it is inserted. Replace the battery while the memory card is inserted into a 
powered-up test set. To retain data and programs, it should be replaced annually. 
See the HP 8920A User’s Guide. The write-protect switch on an SRAM memory 
card will write protect the card when it is set toward the outside of the card.
