Abstract

Claims (30)

1. A method for probing a circuit under test and transmitting a signal therefrom to a circuit under test signal measuring apparatus, comprising the steps of:

(a) selecting a probe tip module from among a plurality of probe tip modules each said probe tip module comprising a probe tip, an amplifier having an input solidly connected to the respective said probe tip, an identification circuit suitable for providing identification data signals regarding the probe tip module in which the identification circuit is positioned, and an output connected to a respective output connector;

(b) providing a distinct probe body having a controller suitable for communicating with said identification circuit, said probe body adapted to receive the output connectors of said plurality of probe tip modules;

(c) connecting the selected probe tip module and said probe body together at said output connector;

(d) receiving the circuit under test signal at said input of said amplifier;

(e) amplifying the circuit under test signal and providing the amplified circuit under test signal to said probe body through said output connector; and

(f) transmitting the amplified circuit under test signal from said probe body to the signal measuring apparatus.

2. The method of claim 1 , further comprising compensating for selected electrical characteristics of the selected probe tip in said probe tip module.

3. The method of claim 1 , wherein the circuit under test is remote from the signal measuring apparatus, and wherein said step of transmitting is conducted over an elongate, flexible cable to facilitate accessing the circuit under test from the signal measuring apparatus.

4. The method of claim 1 , further comprising the step of compensating for selected electrical characteristics of the selected probe tip in said probe tip module based on said identification data signals.

5. The method of claim 1 , further comprising the step of providing a compensation box functionally interconnected with said probe body, said compensation box having a compensation box connection scheme adapted to mate with an associated signal measuring apparatus connection scheme such that said compensation box is configured to mate with an associated signal measuring apparatus.

6. The method of claim 5 , wherein said step of providing a compensation box further comprises the step of providing a compensation box having a compensation box connection scheme, said compensation box connection scheme may be selected from a group consisting of:

(a) BNC;

(b) BMA;

(c) SMP;

(d) SMA;

(e) N-connector; and

(f) future developed connection schemes.

7. The method of claim 1 , further comprising the step of programming said controller to provide information, said information selected from the group consisting of:

(a) information about said probe body;

(b) information about a compensation box functionally interconnected with said probe body; and

(c) information about a cable between said probe body and said compensation box.

8. The method of claim 1 , wherein said step of selecting a probe tip module from among a plurality of probe tip modules further comprises the step of selecting a probe tip module from among a plurality of probe tip modules, the plurality of probe tip modules including at least two probe tip modules selected from a group consisting of:

(a) active testing probe tip module;

(b) passive testing probe tip module;

(c) voltage testing probe tip module;

(d) current testing probe tip module;

(e) optic testing probe tip module;

(f) wireless testing probe tip module; and

(g) future developed connection scheme probe tip module.
