Appendix 2 Updating the M9300A FPGA
Reserving the Reference for a Configuration
Appendix 2 Updating the M9300A FPGA
FPGA updates are not allowed on a Keysight M9300A PXIe
Frequency Reference while it is being shared. To perform M9300A
FPGA updates, reserve the Reference.
Reserving the Reference for a Configuration
If you are running a test in the background with a certain M9300A setting and then
connect a hardware configuration that also contains the same M9300A, you may alter
the test setup that is already running.
If you would prefer to be keep the reference control with the first instance of the
hardware configuration so that a subsequent instance will not take control of the
reference module unintentionally:
1. On the SFP Connect to Instrument screen, click the Advanced control to open
the Options: dialog.
2. Type the following string: ShareReferenceVisaSession=0
This configuration will retain control of the M9300A if you try to open a
new configuration. If you connect a new configuration, that includes the
same M9300A, you will see the following error:
If an existing instance of the SFP is connected to the reference
module in a shared (default) mode, and you try to connect a
second instance of the SFP to the same reference with
ShareReferenceVisaSession=0 Advanced Option, you will get the
resource locked error shown above.
