Step 7: Check M9195B Licensing (Optional)
Step 7: Check M9195B Licensing (Optional)
Upgrade Options
There are four optional licenses enabling special features on the M9195B. These
are:
– Speed —The M9195B comes standard supporting 125 MHz (SR1)
operation. The M9195B-SR2 license option enables the maximum clock
rate of 250 MHz.
– Memory — Standard M9195B operation, M9195B-M01, includes memory
support of 6 million vectors (Mvectors) of pattern memory per channel. The
M9195B-M06 and M9195B-M12 license options enable 64 and 125
Mvectors of pattern memory per channel respectively.
– Multi-Site Operation — Standard operation, M9195B-S01, allows
single-site configuration of the DSR as 16 synchronized channels, while
with the multi-site license (M9195B-S04) the module can be configured
with 4 sets of 4 synchronized channels. In multi-site mode, each site has
its own independent Stimulus Data Sequencer. This enables site
independent clock operation for simultaneous testing. The multi-site
capability simplifies test development. Instead of forcing the test engineer
to create a single test that encompasses all for sites simultaneously, the
user only needs to focus on a single device. The single device test can be
easily replicated for the remaining test sites. In addition to the digital pins,
each site has a high voltage drive channel and an open drain control
channel for relay control.
– Multi-Module Operation — Multiple modules are combined and
programmed together into a single multi-module instrument. This option
includes a SMB to SMB cable which allows multi-module front panels to
be daisy-chained together. With the option license (M9195B-MMS), up to
12 modules can be combined to build systems up to 192 channels
(requires the MMS option for each module plus the appropriate sync cable,
either Y1250A or Y1251A). When modules are combined, they operate in
single-site mode and all channels are synchronized to a single Stimulus
Data Sequencer. It can include all available IO channels in the installation.
There can be multiple PPMU or simple DC level (Static) sites made up of
any channels that aren't used in the pattern site. 
Typical channel-to-channel skew (including across modules) is ±300 ps.
The licensing status of a module can be checked by selecting it through the
Software Front Panel (SFP) and then going to the About Box in the Help
drop-down menus. In the About Box, installed options will be listed after
