This unit
The Ametek/Elgar 4643V is a dual-range manual oscillator module that delivers stable, precise frequency output for integration with Elgar AC power sources. This Series 400 plug-in unIt has decade-dial and range-switch control over frequency selection, enabling low-distortion sine wave generation across 45 Hz to 5 kHz. Manual frequency adjustment combines with optional external programming via analog voltage (6-10 VDC) or external resistance to meet diverse test and calibration requirements.
Calibration accuracy of ±0.001% of set value and a front-panel frequency-limit LED ensure reliable operation within specified bounds. The module accepts single, dual, or three-phase configurations and integrates directly into Elgar power sources via captive-screw front-panel mounting and terminal connector interface.

Ametek/Elgar 4643V — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Ametek/Elgar 4643V. Calibration covers output frequency accuracy, output amplitude accuracy at 50 ohm and Hi-Z load, DC offset accuracy, symmetry and duty cycle accuracy, and arbitrary waveform sample rate accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Ametek/Elgar 4643V faults: BNC output connector wear, output amplifier failure from short-circuit drive, display and keypad membrane switch wear, DDS or DAC failure on 33250A. HP 33120A and Agilent 33220A most common fault is BNC output connector wear from repeated cable insertions. Output amplifier failure on the HP 33120A typically results from sustained short-circuit drive. Agilent 33250A DDS and high-speed DAC failures are rare but require component-level repair and post-repair amplitude verification across the full 80 MHz range.
