This unit
The Keithley 2790-HH SourceMeter Switch System combines high-voltage sourcing, precision measurement, and multi-channel switching in a compact modular instrument. Engineered for automated functional testing, it delivers programmable voltage (50V to 500V) and current (0 to 50mA) sourcing with integrated DMM capability and switching matrices supporting up to 40 channels. Ideal for automotive ignition systems, connector validation, and complex harness characterization where simultaneous source and measure operations are required.

Keithley 2790-HH J — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keithley 2790-HH J. 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 2790-HH J 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.
