Probe and Signal Interfaces
Overview
Teledyne LeCroy oscilloscopes are equipped with a variety of connection
interfaces to allow connection of cables directly to the oscilloscope
channels, or to allow probe connections to the oscilloscope. When probes
are connected, a probe interface is used to power the probe (as necessary),
to recognize the probe type and its characteristics, and to communicate to
and from the probe to completely integrate the probe with the oscilloscope
channel in a number of ways. For instance, active single-ended and
differential voltage probes and current probes use these interfaces upload
gain and offset correction factors from the probe EEPROM's and, in some
cases, automatically compensates responses to achieve fully-calibrated
measurements.
Some oscilloscope product series support multiple probe and connection
interfaces. This can be an advantage when the highest speed signal on a
design requires the use of a high-bandwidth oscilloscope, yet it is also
highly desired to view other low-speed signals in conjunction with the
highest-speed signals so as to debug or analyze a complicated embedded
design. An example would be a high-speed serial data interface, such as
PCIe, that may interoperate with low-speed signals, such as I
2 C or power
supply lines. In this case, the multiple connection interfaces in a single high-
bandwidth oscilloscope would allow connection of passive voltage probes,
current probes, and high-bandwidth differential probes without the use of
additional adapters that cost extra money and may be easily lost or
misplaced. Multiple probe and connection interfaces also provide users the
ability to connect two probes to the circuit on a single channel and switch
between them without disconnecting and re-connecting probes from the
circuit. This function is remotely programmable allowing the interface to
operate like a switch, and the ability to select four out of eight inputs
provides unheard of connection flexibility.
Note: AUX INPUT and AUX OUTPUT connections are typically located on
the Front of the oscilloscope.
