Interface Adapter
TPA-BNC
TekVPI Interface Adapter
TPA-BNC Adapter enables existing
TekProbe interface products (active, differ-
ential, high voltage, current and optical
probes) to be used with Tektronix’ newest
generation of DPO7000 and DPO4000
Series Oscilloscopes, which feature the
new TekVPI probe interface architecture.
Existing TekProbe-BNC probe types
simply plug into the TPA-BNC adapter
which is then plugged directly into any
TekVPI probe channel of the DPO7000
and DPO4000 Series oscilloscopes. The
TPA-BNC adapter recognizes and supplies
the necessary power and serial communi-
cation and offset control as used by the
connected TekProbe product accessory.
Note:
Tektronix probe types using a BNC
connection, or a BNC connection with a
single analog encoding pin for attenuation
factor detection, connect directly to the
oscilloscope’s TekVPI probe interface
and do not require a TPA-BNC adapter.
TekProbe Interface
TekProbe is a probe interface architecture
introduced in 1986, and used on many
earlier models of Tektronix oscilloscopes
including the TDS300, TDS400, TDS500,
TDS600, TDS700, TDS3000B, TDS5000B
and TDS7000 Series. In addition to
coupling the signal from the probe to the
oscilloscope, the TekProbe interface
provides power and offset control to
active probes. It also allows the oscillo-
scope to sense the probe’s attenuation
scale factor and/or probe type.
