  • Measuring current with the ADALM1000

    •  Analog Employees 
    The ADALM1000 is actually a Source/Measure Unit (SMU) at it's heart not a separate oscilloscope and function generator This can be confusing to some users who are maybe not so familiar with a SMU. We haven’t made it all that easy at times either in...

  • DC voltage divider for the ADALM1000

    •  Analog Employees 
    The ADALM1000 can do one thing very well - convert an analog voltage to a digital representation. The 16 bit Analog-to-Digital Converter (ADC) in the ALM1000 signal chain has been designed and optimized for a single voltage range, 0 to +5V. So how ...
