To better handle the power supply needs (3.3V, 5V, 12V, 24V, etc.) of the diverse hardware I work with I replaced my old 3 channel Hameg power supply with a new Rohde&Schwarz HMP4040.
New 4/16 channel Oscilloscope
Since almost every project I did the last decades all use something like I2C, SPI, CAN, RS458, etc. I replaced my old Tek scope with a new Rohde&Schwarz RTM3004 that can do decoding of those protocols, so I don't have to manually count bits anymore.
BK Precision 9206
New 150VDC Power Supply
Since I have several projects for public transportation information systems, where the use of 110VDC is common, I added a BK Precision 150VDC power supply to my lineup of equipment.
New bench multimeter
To be able to better measure things like ADC inputs, DAC outputs, I extended my equipment lineup with a Rigol DM3068 bench multimeter.
