Setting the Write-Protect Switch

The SRAM memory card’s write-protect switch lets you secure its contents from being accidentally overwritten or erased. The switch has two positions as illustrated in Figure 8-8 on page 8-23:

•Read-write– The memory-card contents can be changed or erased, and new files may written on the card.

•Read-only– The memory-card contents can be read by the Agilent 8922M/S, but cannot be changed or erased.

Backing Up the Memory-Card Programs

SRAM memory cards contain a battery to preserve its contents when the Agilent 8922M/S is turned off or when the card is removed. Memory-card contents may be backed up using the following procedure:

Procedure for Backing Up a Memory Card

The program COPY_PL on Agilent 8922M/S ROM backs up Test Procedure and Test Library files onto a SRAM memory card. The program COPY_PL also lets you to initialize the SRAM memory card. (Code files should reside on OTP memory cards; an external “device programmer” is required to download code files into an OTP memory card.)
