Probe Type:
|

|
| |
Your choices are...
|
|
|
| |
Voltage
|
|
A probe that is used to measure voltage. Normally it is connected to an oscilloscope.
|
| |
Current
|
|
A probe used to measure current.
|
| |
Oscilloscope
|
|
Oscilloscope probes have a specified operating bandwidth and in some cases have switchable attenuators built in.
|
| |
Differential
|
|
Differential probes are used to measure differential signals (signals that are referenced to each other instead of ground). Single-ended probes, on the other hand, are probes that measure signals referenced to ground.
|
| |
Logic
|
|
A probe used to measure logic levels in digital circuits.
|
| |
Semiconductor / High Density
|
|
Fine point, spring loaded probes, which are usually mounted in a test jig. They are used to test semiconductor interconnects and high-density circuit boards.
|
| |
Coaxial
|
|
A spring loaded, signal-conducting probe insulated from its shell or shielding tube by a dielectric material. It also has a rated nominal impedance similar to a coaxial cable.
|
| |
Polarity
|
|
Automatically determines the polarity of the circuit under test.
|
| |
Continuity
|
|
A probe that is used to test circuit conditions for continuous connection. It is usually accompanied with a continuity tester.
|
| |
High Frequency
|
|
A probe used to measure high frequency signals.
|
| |
High Voltage
|
|
A probe used to measure high voltage signals.
|
| |
Magnetic
|
|
Magnetic probes sense magnetic fields in solenoid operated devices, stepper switches, relays, valves & coils.
|
| |
Optical
|
|
Optical probes convert optical signals into electrical signals for convenient analysis of oscilloscopes and other devices.
|
| |
Other
|
|
Other unlisted, specialized or proprietary probes.

|
|
| |
Attenuation Factor:
|
|
The attenuation factor is the amount by which the probe reduces the amplitude of the signal being measured. This allows the range of the measuring meter (oscilloscope, for example) to be extended. For instance, a 10X probes reduces the measured signal to 0.1 of its amplitude. This allows the measuring instrument to measure signals ten times larger than what its maximum range allows.
|
| |
Your choices are...
|
|
|
| |
1X
|
|
The probe does not provide any attenuation.
|
| |
10X
|
|
The probe reduces signal amplitude to 0.1 of its value.
|
| |
100X
|
|
The probe reduces signal amplitude to 0.01 of its value.
|
| |
500X
|
|
The probe reduces signal amplitude to 0.002 of its value.
|
| |
1000X
|
|
The probe reduces signal amplitude to 0.001 of its value.
|
| |
Other
|
|
Other unlisted, specialized or proprietary attenuation factors.

Probe Configuration
|
|
|
| |
Your choices are...
|
|
|
| |
Alligator Clip
|
|
A spring-loaded jaw with serrated teeth that hold fast to the point being measured.
|
| |
Bent Metal
|
|
Bent metal contacts (metal spring clips) are relatively fine pieces of metal formed into a curvilinear shape in order to provide a cantilever effect that grants them compliance. These contacts are normally then insert-molded or stuffed into a nonconductive carrier of some sort. A portion of the contact protrudes beneath the carrier for attachment to the PCB by surface mount or through-hole interconnection.
|
| |
Computer / IC
|
|
A specialized probe tip that is used to look at signals on circuit boards and IC chips.
|
| |
Conductive Elastomer
|
|
Conductive elastomers consist of embedded conductive components within a compliant medium. This may be carbon or silver, for example, where it is desired for the entire conductive sheet or column to be common. Alternately, it is possible to make "z-axis only" conductive elastomer, which typically has beryllium copper wires suspended vertically in the compliant matrix. The wires are separated from each other by the insulative compliant compound, and buckle when compressed.
|
| |
Extended - Fine Tip
|
|
A specialized tip that extends the reach of the test probe. It has a fine point on its tip.
|
| |
Flat Blade
|
|
Flat blades are used in power outlets. They are shaped to insure good contact.
|
| |
Hook
|
|
A retractable probe that has a hook shaped tip. It is used to grasp onto a test point.
|
| |
Pin and Socket
|
|
Pin-and-socket is perhaps the oldest and most basic type of connector technology. This generic term refers to any connector scheme wherein a male plug is inserted into a female receptacle or jack.
|
| |
Pincher
|
|
Pincher points are fine, retractable probes that are used to grasp onto test points on circuit boards.
|
| |
Probe Card
|
|
Probe cards are flat cards with many pins used to test semiconductor devices.
|
| |
Spade Lug
|
|
A specialized spade connector that is screwed down to an electrical terminal. The test probe is designed to fit inside the spade lug.
|
| |
Spring Loaded
|
|
Spring contact probes are telescopic electromechanical interconnects. They typically consist of one or more contact members (often referred to as the "plunger(s)") and a helical coil spring, housed within a conductive tube (normally termed a "barrel").
|
| |
Wireless
|
|
Wireless test probes are used to test more advanced board layouts. The conventional wireless fixture makes use of double-ended probes and substitutes a PCB for the fixture's wiring.
|
| |
Other
|
|
Other unlisted, specialized or proprietary probe tips.
