9.6.1 Introduction
This section contains information on the installation and operation of the OMNI (Output Matching
Network Impedance) impedance network to be used with the California Instruments
i-or iX-series of power sources.
9.6.2 General Description
The OMNI impedance network adds inductive and resistive impedance to California Instruments
i-or iX-series power sources. This additional impedance brings the combined system impedance
up to the levels required of the power source for IEC 555-3 and IEC 1000-3-3 (flicker) testing.

NOTE: To prevent damage to the OMNI unit , the BYPASS mode must be
selected when the power source is operated on low output voltage range
or if currents in excess of OMNI ratings will be drawn.
