TIA Series Comparison

The TIA-525, 527 and 952 units have BNC outputs for direct connection to your oscilloscope or digitizer. The TIA-525 and TIA-527 have selectable AC/DC coupling while the TIA-952 is AC coupled. The TIA-525 and 527 have dual power capability, with battery and external universal power supply and offer a bandwidth of DC to 125MHz while the TIA-952 has a bandwidth of 3KHz to 800MHz. The TIA-527 is a matched InGaAs system. The TIA-525 is available in a free space configuration.


The TIA-1200, 2000 and 3000 use a type K SMA female output connector. The TIA-1200 and TIA-2000 have bandwidths of DC to 12GHz and 20GHz respectively, and are DC coupled. The TIA-3000 is AC coupled with a bandwidth of 100KHz to 11GHz. Patch cords and adapters can be supplied to mate with various fiber optic connectors and systems.
