Meters on my workbench

FeelElec FY6900 60 MHz Arbitrary DDS Signal Generator, with 2 channel signal output, and 1 channel counter / Frequency meter that woks between 0.01 Hz and 100MHz. It can be controlled via USB and has an API available - Review.


As an replacement for my vintage Phillips PH 3217 50 MHz Oscilloscope, my struggle with settings, was not worth it, so I ended up with an Hantek DSO4204B Oscilloscope, 4Ch 200Mhz 1GS/s Sample Rate, I find it convenient with the auto-scale button. At my hobby use, it has all the functions I can imagen I could need, including FTT and the ability to decode data traffic - Review of the DSO4xx4C the version with build in Signal Generator.

I was surprised, I would have bought the 80MHz version since a simple hack, can change it to a 200MHz Oscilloscope, but if I calculated the combined cost with the 4 additional 200MHz probes, it would have been more expensive, then just buying the 200MHz version.

Be aware when you are measuring at main voltage. If phase and neutral not is connected in the same side of the plug, it could change in some extension cables. Neutral and ground has the same electrical potential, and the BNC plug is grounded. It will end up in a fried channel. You can prevent this, if the device you are testing, is supplied from an insolating transformer.


East Tester ET4402 a Desktop LCR-meter for measuring Capacitance, Resistance, Impedance, Capacitance, Inductance and ESR. I selected the ET4402 version that measures components with frequency between 10 Hz ~ 100 KHZ bandwidth, with kelvin probes - Review.


East Tester ET3240 a 4.5 Digit benchtop multimeter. It can messure voltage down to 0.001mV and current down to 0.001μA. Review.


East Tester ET5410 Programmable DC Electrical Load, 150V, 40A, 400W. With the basic measurement modes of CC, CV, CR, CP, CC+CV, CR+CV and Dynamic test mode are provided. With an option for control via USB - Review.


TinySA Spectrum Analyzer or signal generator, with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz or Signal Generator with two output, sinus output for 0.1MHz - 350MHz and square wave output for 240MHz-960MHz when not used as Spectrum Analyzer, maximum input id +10dBm, so I have collected parts for an RF Attenuator - Review.

NanoVNA a very tiny handheld Vector Network Analyzer (VNA), that works on frequencies from 50KHz to 900MHz - Review.

TinySA and NanoVNA

My USB logic analyzer is a clone of a logic analyzer from I have a bad conscience about Saleae being cheated for there use of there software, but when the original costs 329 USD, and a clone only costs around 7 USD, then there must be weighty arguments before I can recommend the original. Both <25 MHz versions, When I do not have experienced issues with the clone - Review.

I have a couple of Transistor Tester lying around, of different ages. they are good at testing / identify components and verify their specifications - Review.

MiniWare DT71 Tweezer with LCR-meter. I do not use it for soldering, but to verify values of resistors, capacitors, small inductors and help me position diodes in the right direction - Review.

In addition to the instruments on my work table, I have several handheld measuring instruments.

Safety first: Be aware of the qualification of measuring instruments, at a category that is too low, you risk the instrument exploding, in the event of short circuits or transients.
CAT I: Electronic devices, everything from a small circuit board to a larger unit with high voltage but low energy
CAT II: Single-phase AC loads, cars, appliances or portable tools.
CAT III: Electrical House installations.
CAT IV: Switchboards, outdoor and other installations, with high energy and risk of transients.
