The Tektronix 2302 is a portable battery simulator that emulates battery performance and monitors power consumption in battery-operated electronic devices. It delivers a single-channel output with variable voltage capable of simulating discharged rechargeable batteries, programmable source compliance accurate to ±(0.16% + 5 mA), and ultrafast transient response to load current shifts. The instrument measures DC currents as low as 100 nA and captures peak and average pulse currents spanning 60 µs to 833 ms, with long integration mode extending measurements to 60 seconds for pulse trains exceeding 850 ms period.
