I did a review of an OWON SPM6103 60V, 10A programmable power supply and 20,000 counts DMM all-in-one switching power supply, the review and teardown video is linked below. In this blog post, let’s take a look at some of…
The FNIRSI DPOX180H is a digital phosphor dual channel handheld oscilloscope with a builtin function generator. It boasts a single channel bandwidth of 180 MHz. I was at first very skeptical of its bandwidth claim, but upon further verification, the…
I reviewed a NanoVNA-F V2 vector network analyzer a while ago. V2 has a frequency range from 50 kHz to 4.4 GHz (with the latest firmware). As an update to the V2, SYSJOINT recently released an upgraded NanoVNA-F V3 which…
I did a review and teardown of a Miniware TS1C cordless soldering station. This soldering station is rather unique in that the soldering iron is powered by a supercapacitor instead of a traditional battery. While supercapacitors have limited capacities, they…
A process meter is mainly used in industrial settings and typically for loop calibrations. It can do basic DMM measurements and has many unique features such as the ability to source and sink current up to 20 mA. These features…
The tinySA Ultra is quite a capable spectrum analyzer. In this blog posting, we will take a look how to add a tracking generator to the tinySA with the help of an external mixer. I made a detailed video on…
tinySA Ultra is an affordable spectrum analyzer geared towards HAM radio operators, RF enthusiasts and electronic hobbyists. With the Ultra mode enabled, it boasts a calibrated frequency range up to 6 GHz and can observe signals up to 12 GHz.…
MUSTOOL ET5410A+ is a single channel programmable electronic load and battery tester. It is capable of sinking up to 40A of current and can dissipate up to 400W. The ET5410A+ can also be controlled remotely via PC. I did an…
I got my hands on a recently released Zotek ZOYI ZT-702S handheld digital oscilloscope. It is a combination of a 10 MHz bandwidth single channel oscilloscope and a 9,999 count digital multimeter packed in a single device. Compared to the…
Early last year when I reviewed OWON’s HDS2102S, I was impressed as the performance of OWON’s then top of the line HDS200 series 100 MHz 3-in-1 handheld oscilloscope. It had some quite noticeable improvements compared to the HDS272S 70 MHz…
A couple of years ago, I reviewed a Kaiweets HT118A multimeter. The HT118A is a 6,000 counts multimeter and this time around I got an E version of the HT118. The HT118E in comparison is a 20,000 counts DMM. A…
Over the last year, I have done teardowns of a few handheld scopemeters including a Hantek 2D72, an Owon HDS272S and an Owon HDS2102S. This time around let us take a look at this ToolTop ET829 3-in-1 handheld meter that…
I did a thorough review of a Micsig STO1004 DSO last week. It is a powerful four channel scope taking the form of a tablet computer. This time, we will open it up and take a look inside.
A dedicated LCR meter is a luxury for many electronics hobbyists, but it is extremely useful when dealing with analog circuitry where the component values need to be known precisely under the given frequency conditions. I have an Agilent 1731B…
I received yet another NanoVNA for review. This time it is a S-A-A-2 (NanoVNA V2) with N connectors instead of SMA connectors found on the other NanoVNAs I reviewed before. This NanoVNA is based on a fully open-sourced design, with…
