Using earlier versions
of software with your
80A01 module
The 80A01 prescaled trigger amplifier was designed to be used with software
release versions 1.1.0 and later of the 8000 series sampling oscilloscope
application. If your instrument is running a release prior to version 1.1.0,
Tektronix recommends that you upgrade your instrument to the latest version.
To determine the software version running on your CSA8000 or TDS8000, select
About TDS/CSA in the Help menu from the user interface. This command
displays the About TDS/CSA dialog which lists the current software version
number.
If you find that you are running an older version of software, please visit the
Tektronix website at http://www.tektronix.com to find out how to get an upgrade
version mailed to you. When you visit the Tektronix website, select the Oscillo-
scopes page. You will find upgrade information there.
While the 80A01 was designed to be used with software release 1.1.0 or later, it
can be used with earlier versions of the software with the following limitations
and non-standard behavior:
1. If the 80A01 is inserted in the left-most small slot (labeled CH1 / CH2) of
the TDS/CSA8000 and at least one optical module is present, the 80A01 will
behave normally.
2. If the 80A01 is inserted in any other slot or there are no optical modules
present, the following behavior will be seen:
a. The instrument will behave as if the odd-numbered channel for the slot
in which the 80A01 is inserted is available for acquisition. Thus if the
module is inserted in the right-most small slot, the TDS/CSA8000 will
believe that it can acquire data on Channel 7. Turning on acquisition on
this "pseudo-channel" will result in a waveform being acquired from a
floating input. This pseudo-waveform will appear as a DC level with all
points having amplitude approximately equal to zero.
b. The System Properties dialog (accessed by selecting System Properties
from the Utilities menu in the user interface) may contain incorrect
information.
In either scenario (1. or 2.), the actual performance of the 80A01 in amplifying
RF signals is not degraded.
