Key Features Dual-polarity design supports both positive and negative supplies from a single instrument. High-resolution 10 mV voltage and 1 mA current metering enables precise circuit characterization. Auto-tracking simplifies biasing networks by maintaining symmetric voltage pairs with 1% tracking accuracy. Low ripple and noise (< 350 µV RMS) suits sensitive analog and RF applications. Output current derates 3.3% per °C above 40°C.
