Micsig 700V 100MHz High Voltage Differential Probe kit 3.5ns Rise Time 10X/100X Attenuation Rate Oscilloscope Probe Kit Accessory DP10007

I use this with my Siglent SDS2204X Plus oscilloscope to measure a voltage with a different reference than the other 3 channels. I do not generally use it to measure higher voltage ranges, keeping it at 10x for most measurements. Recently, I was measuring 100BASE-TX Ethernet signals effectively. The bandwidth is sufficient for this application. As with any differential voltage probe with "DMM-style" leads, twist the leads together to improve the performance (noise rejection and high-frequency attenuation). The set comes with the probe itself as well as a USB cord (for power). It does not come with a USB power adapter but will work with any, even the 5V USB on your oscilloscope. The probe connects to the oscilloscope via a BNC cable. Unlike the expensive Tektronix probes I use at work, this uses a 1 Mohm input impedance, not 50 Ohm. This was surprising to me, but the performance does not seem to suffer due to mismatched coaxial cable impedance. The kit also comes with two sets of gigantic test clips, obviously more suitable to high-voltage than small-signal work. The silicone leads attach to these clips or to any DMM probes. I fabricated an adapter to allow me to use mini-grabber clips, which are much more suitable for small-signal work. Simply use a BNC to shrouded banana jack adapter for this purpose, then attach a banana to mini-grabber adapter.

I got this a while back and it is different than the picture, the old style white color unit, but similar specs. I like the 10X and 100X version. Plenty of YouTube reviews to watch. Performance is as expected. Good build quality, size, accessories, and packing/protection. Does not exactly meet its spec'ed CMRR (according to online reviews), but that does not bother me and it works well for my purposes. Decent value for the money.

The MicSig Diff Probe set is exactly what the casual user of O'Scopes needs to protect his instrumentation from High-V oversight. In fact, I think everyone who purchases a new level of O'Scope should include a set of Diff Probes at purchase. There should be no attaching scope probes to live circuits that see AC anywhere without first relying on the Diff Probe firewall. It is not because the circuit under test might be live, but what about a probe slip-up? There are many various probe sets MicSig offers. Start out with the simple set and work upwards. If you've spent hundreds on an O'Scope it becomes very worthwhile and MicSig is a very trustworthy name. I wish I could afford a high-end MicSig probe set right now, as there would be an order in place.

I build a custom line of tube hi fi amps and also service McIntosh Dynaco and Marantz tube amps. Sometimes a differential probe is needed . This is a well made entry level probe, and it is accurate enough for my needs.

If you are working on computers and Arduino circuits, you do not need this and will affect the precision of your measurements. When dealing with high voltages and power supplies, a differential probe provides an added layer of safety by isolating the oscilloscope from the circuit under test. This helps protect your expensive oscilloscope and may save your life from potential electrical hazards. This probe is accurate, and I had to buy two for my use cases.

It works quite well with my Siglent SDS1104X-E scope. Accuracy seems good. I was not satisfied with the 2 pincer clips (too big) and there were no hook clips provided (supposed to be included per the description) which I prefer for tight working spaces. I did purchase Mueller Electric CO / BU-P4723 hook clips.

A definite asset when you need to float the ground connection.

Crazy good value. The bandwidth is as advertised. Checked against my Rigol stock probes on the test output waveform provided on the scope. The waveform exactly matched my Rigol probe when it was set to 10x attenuation. The LED indicators are great as well. Would recommend to hobbyists and professionals.
