How to Set Up the 9611B for Operation
Use the following procedure containing the individual commands detailed above from the command
line interface:
1. impedance [<50|1000>] (set the value of impedance to either 50Ω or 1000Ω).
2. frequency [<1-15>] (set the value of frequency/time duration between valid signals).
3. voltage [<1-5>] (set the reference threshold for inputs A and B)
4. switch A (select input A ).
5.

6. switch B (select input B ).
7. finput <B> <disable|[enable <low|high>]> (set enable and high/low logic for input B).
8. switch A (select input A ).
9. switch A auto (set input A as armed).
How to Upgrade Software
The 9611B has a single partition into which the FPGAprogram image can be loaded. For the DSP
program image, there is a choice of two partitions into which the image can be loaded, partition A or
partition B.
It is important to realize that the DSP and FPGA images are created as a matched pair. It is therefore
most important to upgrade both the FPGA and DSP images at the same time. The upgraded version
of the FPGA image should be loaded into the single FPGApartition. The “upgfpga” command
installs the FPGA image into the single FPGA partition, overwriting the prior image.
The upgraded version of the DSP image should be loaded into either DSP partition A or DSP par-
tition B. An argument to the “upgdsp” command selects whether the DSP image is written to the A
or B partition.
The “setpart” command tells the 9611B which DSP image to use at boot time: A or B.
The idea of the A and B partitions is to provide a place for the last known working DSP image and
another for an upgrade image.
When the 9611B is received, the factory image will be in partition A.
The first upgrade should therefore be loaded into B. The 2nd upgrade into A, and so forth.
The setpart command will also need to be set to the same partition the DSP image was loaded into.
Whenever the DSP starts, it loads its program image into RAM from either flash partition A or B,
depending on the current position of an internal pointer. The system then boots up from the selected
partition.Next, the system loads the FPGA with an image that resides in the single FPGA partition.
When upgrading the firmware, the customer uses the 9611B Boot loader CLI to install new FPGA
and DSP images separately as follows.
