• For CMC 56 test devices with serial-no < DAxxxx:
If the CMC test system is configured for its internal amplifiers:
Do not connect the CMA 56 (with connected test object) to the CMC 56
or leave it connected!
The control signals are always present at the Lemo connector at the
rear of the CMC 56. When the internal amplifiers are configured, these
signals are not calibrated and are therefore invalid.
(For serial-no DAxxxx, the signals at the rear connector of the CMC 56
are suppressed if the internal amplifiers are used.)
• For the position of the sliding switch on the rear panel of the device see
the instructions in section 4.2.2.
• Please check that your OMICRON software shows the name and serial
number of the CMA 56
(e.g. CMA 56 AJ123N).
Instructions:
If the amplifier is connected to the CMC test device through the interface
"Gen. out 7-12", then the CMC reads this, and all other information
about the amplifier, automatically through this interface.
For older test devices this interface is not standard, only the "Gen. Out
1-6" (or "ext. Ampl.") interface. If the amplifier is connected to this
interface, then the information about the amplifier must be read from an
AMP-file. The AMP-file defines the most important parameters of an
amplifier (name, current or voltage amplifier, amplification factor, etc.)
and is described in Chapter 3 of the CMC DOS Software Handbook.
