Logic analyzer probes
There are many logic analyzer probes of varying quality and price on the market (see photo for a small subset).
Low-end probes
There are various simple and cheap logic analyzer probes available from various sources. Some logic analyzers are also shipped with this kind of probes out of the box.
They're generally not recommended, if you can avoid them. They're usually of low quality, break/bend/fail relatively quickly, and cannot be easily used to probe finer-pitch devices/pins. Probes 1 and 2 (see photos) also have the additional disadvantage that they're hardwired/soldered directly to a custom logic analyzer cable, which means they cannot be easily replaced, swapped, or removed and used for other purposes (which is possible with the other probes). See below for better alternatives.
Sometimes you can also replace the probes shipped with your device by a better-quality cable/probe set, e.g. in the case of the RockyLogic Ant8 probe cable (see photos).
Quality probes
The better-quality (and minimum recommended, in our opinion) probe type is the EZ-Hook. This type of probe is of sufficient quality, doesn't break too easily, and the grabber is small enough to probe most fine-pitch devices one usually encounters in day-to-day probing.
The Agilent probes (shipped with some Agilent oscilloscopes with integrated logic analyzer) seem to be exactly the same as the EZ-Hooks. They're probably merely rebranded for Agilent (just a guess).
The Tektronix probes are different, but of similarly good quality as the EZ-Hooks.
The ZEROPLUS probes seem to be custom-made by/for ZEROPLUS and are of similarly good quality, too (only one pin where you can attach, though; most other probe types usually have two).
Saleae used to deliver EZ-Hooks with the Logic; currently at least the Logic16 comes with a cheaper copy. The Link Instruments MSO-19 comes with the same probes (in different colors).
High-end probes
There are of course also various higher-end, special-purpose probes which are much more expensive. They allow for probing much smaller pitch devices, for example.
Products / where to buy:
- Electro-PJP 6800: Micro pincer clip w/ 0.8 mm (0.031") (male) pin
- Reichelt: Electro-PJP CLIP 6800 RT "Challenger-clip" (one probe, red)
- Electro-PJP 6800-6: Kit, 6 clips + 3 holding rods + 6 leads
- Reichelt: Electro-PJP MS 6800-6 (set of 6 probes)
Oscilloscope probes
Low-end probes
There are various cheap oscilloscope probes which are shipped with many PC/USB oscilloscopes and also some standalone bench scopes.
The two major manufacturers seem to be:
- Globaltone
- Models: P6020, P6040, P6060, P6100, P6200, ...
- Globaltone AliExpress.com store
- Protek (TODO: URL?)
