Signal probe with remote control function

Signal probe apparatus for use with and for controlling a signal measuring device operable to perform a plurality of functions, said apparatus comprising:

• a plurality of signal lines connectable to said signal measuring device;
• means for supplying a signal to be measured to one of said signal lines;
• a plurality of resistors, each being connectable across a number of said signal lines;
• and
• switch means selectively connecting respective ones of said resistors across said number of signal lines to produce a respective predetermined resistance value thereacross which represents a respective one of said functions so as to provide an indication for said signal measuring device to activate the respective function, thereby controlling said signal measuring device.

Signal probe apparatus for use with a signal measuring device operable to perform a plurality of functions, said apparatus comprising:

• a plurality of signal lines including ground and sense lines connectable to said signal measuring device;
• means for supplying a signal to be measured to one of said signal lines;
• attenuation means for attenuating said signal to be measured by a predetermined attenuation amount;
• switching means including a sensor resistor connected across said ground and sense lines and having a resistance representing said attenuation amount, and a plurality of additional resistors each being individually connectable in parallel with said sense resistor for selectively producing different predetermined effective resistance values across said ground and sense lines, each predetermined effective resistance value representing a respective one of said functions to be performed by said signal measuring device, the effective resistance value nevertheless being within a predetermined range of resistance values so as to identify said attenuation amount to said signal measuring device;
• and
• activate means connected to said switching means to provide an indication to said signal measuring device to activate the function represented by the selectively produced predetermined effective resistance value.
