Description
A supply that also measures well can replace a separate source and meter on the same bench. The Keithley 2280S-32-6 power supply delivers up to 32 V and 6 A, which is 192 W, and lists current measurement resolution down to 10 nA. Lost in HCM lists it for rental and sale.
Why measurement resolution matters
Battery-powered products spend most of their life asleep, drawing tiny currents. A source that resolves small steps lets an engineer see that standby draw while the device is powered. The listing says resolution reaches down to 10 nA. Because that figure is a best case, ask Lost in HCM which current range delivers it.

| Output noise | Less than 1 mV RMS |
A quiet output for sensitive circuits
The listing gives output noise below 1 mV RMS for this model. That matters for analog front ends, sensor boards and reference circuits, where supply noise shows up in the result. Compare the figure with your own noise budget before you commit.
Reading the accuracy line
Voltage programming accuracy is 0.02% plus an offset that depends on the model. The offset is not in the listing, so read the Keithley datasheet for this exact model before you write a tolerance into a test plan. Then record the figure with your results.
On the bench or in a script
The product photo shows a color display, a rotary knob, a numeric keypad, a front USB port and three output terminals. For automation, the listing names USB, GPIB and LAN. As a result, the same unit works for hands-on debugging in the morning and a scripted run at night. In short, the Keithley 2280S-32-6 power supply covers both roles.
Rent or buy the Keithley 2280S-32-6 power supply
Rent when a design review or a short qualification needs measurement-grade power. Buy when the unit will anchor a permanent station. Then request a quote from Lost in HCM and list your dates, site, leads and software. For other options, see more power supply listings, visit Tektronix, or contact SMK Vietnam.
2280S-32-6 questions
How small a current can it resolve?
The listing says current measurement resolution reaches down to 10 nA. Ask which range gives that figure.
What does the accuracy line mean?
Voltage programming accuracy is 0.02% plus an offset that depends on the model. Check the datasheet for the offset.
Which ports can I use for automation?
USB, GPIB and LAN, according to the listing.
