This unit
The Keithley 2604B is a dual-channel, 4-quadrant source-measure unit (SMU) that combines power supply, current source, digital multimeter, arbitrary waveform generator, pulse generator, and electronic load functionality into a single benchtop instrument. With 6½-digit resolution and Test Script Processing (TSP) technology, it executes embedded test programs directly on the device for high-throughput precision testing. The 2604B sources and measures across ±100 mV to ±40 V and ±100 nA to ±10 A (pulse), delivering up to 200 W total output power.
It interfaces via USB 2.0, LXI-C (LAN), GPIB, and RS-232, and is compatible with Keithley's IVy mobile app for I/V characterization on Android platforms.

Keithley 2604B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keithley 2604B. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Keithley 2604B faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.
