TCA75 Impedance Conversion Adapter Instructions
Connecting the TCA75 Adapter to the Host Instrument
The output of the TCA75 adapter connects directly to the TekConnect interface
on Tektronix TDS6000, TDS7000, and CSA7000 Series oscilloscopes, as shown
in Figure 2. The TCA75 is not compatible with oscilloscopes that do not have
the TekConnect interface. The shell of the input on all oscilloscopes must
connect to earth ground.
The TCA75 adapter connects to the host instrument through the TekConnect
interface. The TekConnect interface features a spring-loaded latch that indicates a
reliable connection has been made to the TekConnect host instrument. Slide the
TCA75 adapter into the TekConnect receptacle on the host instrument. The unit
snaps into the host instrument when fully engaged.
NOTE
. After connecting the adapter to the oscilloscope, run the
Probe Calibra-
tion Routine
described on page 11 to ensure accurate measurements.
To release the TCA75 adapter from the host instrument, grasp the adapter,
depress the latch button, and pull it out of the TekConnect receptacle.
