The TDP7700 Series probes are designed to probe high-frequency, low-voltage
circuits. Before probing a circuit, take into account the limits for the operating
voltages discussed in this section.
■ Max non-destruct input voltage
■ Input signal dynamic range
■ Offset voltage
■ Operating voltage window
Figure 7: TekFlex probe tip inputs
The maximum input voltage is the maximum voltage to ground that the inputs
can withstand without damaging the probe input circuitry. The TekFlex active
probe tips include some over-voltage protection circuitry at the probe tip signal
inputs. (See Figure 7: TekFlex probe tip inputs
suppression diodes, Da and Db, provide bidirectional voltage clamping of signals
applied to the probe tip inputs. These TVS diodes limit potential ESD damage as
well as signal over-voltage damage to the active tip buffer amplifier device.
CAUTION. To avoid damaging the inputs of the probe, do not apply more than
±15 V (DC + peak AC) between either probe input and ground.
