The Input / Output Impedance Measuring Set enables the engineer to perform input impedance, output impedance, and audio susceptibility measurements on systems while the systems are under operational power. The Measuring Set is used in conjunction with Venable Frequency Response Analyzer Systems hardware and software (see Products page).
The Measuring Set consists of a power amplifier, step down isolation transformer, and interconnecting cables. The power amplifier has one manual gain adjustment but does not require calibration.
The set extends the Frequency Response Analyzer oscillator drive to include high current / low impedance applications. All Venable System features are fully operational including servo. All precision control and measurement is performed by the automatic Venable System. The amplifier utilizes rugged self-protection circuits for routine overloads.
The isolation transformer enables direct injection of test signals into the customer's systems while under full power and loading. The transformer is designed to carry substantial DC without core saturation for undistorted drive. Measurement Sets are optionally available in the 50 amp (IOZ-50) and 100 amp (IOZ-100) ratings, depending on the current requirements of the system under test.
- Output Power — 293 Watts into 4 ohms( 1 channel driven).
- Output Voltage (Power Amplifier) — 34.2 VRMS into 4 ohms.
- Output Voltage (Secondary of Transformer) 16.5 VRMS into 1 ohm.
- Direct Current through transformer without core saturation:
- IOZ-50 — 50 amps
- IOZ-100 — 100 amps
- Power Requirements 115 VAC 60 Hz 15-20 amps. Other voltages are available by special order.
