circuitry to synchronize the internal clock to an incoming asynchronous
bit stream up to 2 Mb/s.
Each of the two serial channels in the 6810 is connected to a set of
transceiver modules that accepts many common signal levels and that
can be programmed for custom signal levels, if necessary. You can use
the instrument driver to select all signal levels. The transceivers
available to each 6810 serial channel are listed below:
•
RS-485 differential transceivers
•
RS-232 transceivers
•
Programmable transceivers that adjust to any voltage range
within ±10 V to a resolution of 40 mV, including such common
signal levels as 5 V TTL, 3.3 V, and ECL
The 6810 device also includes eight digital I/O signals for
general-purpose input and output. You can use those I/O signals to
control test signals on a device. These digital I/O signals normally
operate with 5 V TTL characteristics, but they can also operate with an
alternate power supply, for special low-voltage applications.
National Instruments provides many cabling options for the
6810 device to integrate it with your existing test systems. To assist you
with building manufacturing test systems, National Instruments
provides an application note that explains all the cable and connector
options for the 6810 device, Application Note 105, Connector Options
for the 6810 Serial Data Analyzer. Please contact the office nearest you,
or call National Instruments for more information on obtaining this
